Beyond MSC and Amphibs: Unconventional Sealift

Strategic Sealift Topic Week

By Benjamin DiDonato

As the Department of the Navy implements the Marine Corps’ Expeditionary Advanced Base Operations (EABO) and the Navy’s Distributed Maritime Operations (DMO) concepts, sealift and logistics plans must also adapt to support them. This process is already well underway with the development of the Light Amphibious Warship (LAW) and a range of drone efforts to deploy and sustain small, forward deployed units.

Unfortunately, the ability to support the numerous small positions, as envisioned by EABO, is limited more by the number of deployable hulls than the capacity of those hulls. Thus, while the new platforms will help, it will take time for them to arrive, and they will almost certainly not be enough to satisfy the demand for distributed sealift when they do.

This paper proposes a complementary solution which could be implemented immediately and continue to operate in parallel with these new platforms to further increase sealift capacity and flexibility. Simply put, warships can provide sealift support for EABO forces. This would naturally have to fit in with other tasking for these ships, so it generally won’t provide predictable resupply, especially when using high-demand assets, but it would still provide additional sealift capacity at essentially no cost.

The implementation details are naturally dependent on tactical, operational, and strategic plans which cannot be publicly discussed in full, and which will inevitably be further refined by experiments and wargames. That said, it should be readily apparent that supplies can come from shore facilities or large sealift ships operating farther back for safety, with fresh water being particularly relevant to this discussion since it can be generated aboard ships and transported ashore in collapsible bladders to minimize its impact on the ship. It’s also worth noting that keeping large sealift ships further from the front puts them closer to friendly shores, reducing their transit time and allowing them to deliver supplies at a higher rate.

With these basics established, we can move on to a brief overview of the opportunities each ship type presents.


Perhaps the most familiar combat platform in this discussion is the submarine. The special forces community is very familiar with operating from submarines, and submarines are likewise familiar with hosting special forces. Therefore, it would be simple to task special forces with EABO-type missions using this deployment method. Naturally, the robust joint special operations community could easily use its existing pipeline to train Marines to deploy from submarines as well, so this offers an extremely covert and survivable, albeit low-capacity, sealift option.

It’s also relatively easy to improve the ability of submarines to support EABO forces by developing self-propelled cargo pods to bring supplies ashore. Such a pod might be as simple as a cargo tube with a motor and compass that drives in a pre-programmed direction until it beaches itself, and could be strapped to the side of the sub or carried in the new Virginia Payload Module (VPM) in addition to existing deployment options.

Finally, it may be worth revisiting the old amphibious warfare submarine concept in the future Large Payload Submarine to further enhance these resupply capabilities and split the underwater missile carrier role onto a drone.

Carrier Strike Groups and Traditional Surface Combatants

Aircraft carriers and traditional surface combatants merit discussion under the same heading because aircraft carriers are always escorted, relatively few traditional surface combatants operate independently, and yet escort vessels operating independently offer relatively similar opportunities to full carrier groups, just at a smaller scale.

Note that this section’s “traditional surface combatants” includes Ticonderoga-class cruisers, Arleigh Burke-class destroyers, Zumwalt-class destroyers, and future Constellation-class frigates because all these ships offer relatively similar opportunities at this level of discussion.

While aircraft carriers and, to a lesser extent, their escorts, are obviously not designed for amphibious warfare, there are clear similarities to amphibious warships. Most critically, they operate helicopters, and now the CMV-22B Osprey Carrier Onboard Delivery Aircraft, so they could easily utilize established amphibious warfare techniques to deploy personnel, supplies, and heavy equipment over long distances. Marines and smaller supplies could be distributed across the strike group, while heavy equipment could potentially be stored on the carrier’s hangar deck if space is available.

Alternatively, any version of the V-22 could be flown to the carrier for refueling, and then sent on its way to provide rapid, long-range deployment with no impact on the carrier’s air wing. This would protect vulnerable sealift ships through the relative safety of distance while still letting their aircraft reach their destinations, and could also facilitate staging from still more distant (and less vulnerable) shore facilities.

Finally, while it would probably be too risky to bring an aircraft carrier into boat range of the shore, supplies and personnel could be transferred to a smaller platform like LAW, an Unmanned Surface Vessel (USV), a patrol ship, a Coast Guard cutter, a commercial vessel, etc. which do have the range to act as surface connectors for the carrier.

Independent surface combatants have a wider variety of options for unconventional sealift, although this flexibility is offset by the variety of missions they may be assigned and their more limited resources. For example, while they could stage V-22s or perform organic airlift with their H-60-family helicopters, this could conflict with ASW operations, especially if the ships’ aircraft are used. Alternatively, delivery ashore could be done by boat since these ships can afford to get closer to the coast than a carrier, especially if they are called on to provide fire support for EABO Marines. Nevertheless, the range and payload of a RHIB is still a limitation. The most attractive option is transferring cargo to a larger delivery platform as discussed above, but this may be difficult to accomplish in practice since these surface combatants weren’t designed to offload heavy cargo or personnel to a smaller vessel. Still, in spite of these limitations, the number of destroyers currently in service and future frigate plans makes surface combatants an important option for nontraditional logistics. Consequently, these platforms will probably offer the greatest return on investment as the Navy explores ways to implement this concept.


The misnamed Littoral Combat Ships would be particularly useful for nontraditional sealift. Since these ships are better described as drone carriers, they have the internal volume and launch capacity to deploy substantial equipment or carry specialist facilities to support other units in theater. Their high speed will also be useful for rapid forays into dangerous waters, and the reduced demand for other missions means they can more easily be tasked with these support roles.

On the specialist facilities front, the modular nature of these ships means it would be easy to build very capable medical, repair, C2, or intelligence facilities into their mission bays. This would provide much greater mobility and survivability for these support activities than island-based EABO installations, especially if additional air and missile defense capabilities like a Mk 56 lightweight vertical launch system for the RIM-162 ESSM are also added.

Lightly Manned Autonomous Combat Capability (LMACC)

While it’s easy to see the future LMACC as a simple corvette since it mounts heavyweight anti-ship missiles on a 600-ton hull, sealift is a core part of its design. Its survivability is greatly enhanced by blending into littoral clutter and it is intended to shoot targets spotted by other forces. This means it will preferentially operate in conjunction with EABO Marines so virtually every combat mission will be ideally tailored to provide sealift support for the Marines. Its very long range also provides operational flexibility to perform secondary lift between islands and act as a connector for larger vessels operating further back. The only major limitation is that its 11m RHIB can’t carry heavy equipment, but its very shallow draft and navigation sonar will let it get close enough to shore for Marines to swim if required.

Furthermore, LMACC is heavily armed for land attack and well equipped for missile defense, especially using electronic warfare, so it is uniquely suited to high-risk missions. When islands are contested and too dangerous for most platforms to approach, LMACC can reinforce or extract embattled Marines, provide fire support, and sink hostile warships. This means LMACC not only increases total sealift capacity, but provides unique capabilities not available anywhere else in the fleet.


In summary, the Navy’s existing fleet of warships offer opportunities to expand sealift capacity, and future platforms promise unprecedented new capability at minimal cost. These new distributed operating concepts synergize well with the numerous hulls but limited cargo capacity of these nontraditional sealift platforms to expand the reach of the American combat logistics system. Since these hulls already exist, the Department of the Navy can rapidly test and implement these concepts and continue them in parallel with current sealift expansion and recapitalization plans to improve overall capacity.

The use of warships as nontraditional connectors can also reduce risk to the logistics fleet by keeping these large, vulnerable ships further from the enemy. This obviously isn’t a silver bullet that will solve every problem, but it could be a useful piece of a future logistics system and help the Joint Force affordably meet overall needs.

Solutions to Revitalizing America’s Strategic Sealift

Strategic Sealift Topic Week

By Todd M. Hiller, P.E.

“. . . without their skill and devotion to duty our men and materiel could not have been delivered. . . “President Franklin D. Roosevelt

The U.S. flag commercial fleet and government owned vessels serve a crucial capability to successfully execute and accomplish USTRANSCOM’s (USTC) worldwide operations by sea. Ongoing issues occurring in the global commons have pressured USTC reliance on the U.S. Merchant Marine through the Military Sealift Command (MSC) and the Maritime Administration’s (MARAD) Ready Reserve Force (RRF).1

Enduring commitment to historic naval functions of deterrence, sea control, power projection and maritime security remains essential to American national strategy; however, the security conditions have become more sophisticated and uncertain, forcing the Department of Defense to change how it conducts sustainment operations. Through a distinguished history of sacrifice, valor and courage, the U.S. Merchant Marine has proven its tenacity in support of a common calling to serve the nation.

Today, threats continue to compel the United States’ need for strategic sealift. Considering the nation’s dependency on imported products, it is timely to reconsider just how dependent the international supply chain is on the primary conveyance for cargoes coming to and from the United States. Over 90 percent by volume or weight comes by sea, but American flagged carriers account for less than 2 percent of these cargoes. American dependency on foreign-flag vessels will inevitably become more problematic with the continuation of stop-gap measures to meet national security requirements.

With a bi-polar hegemonic world, the U.S. needs to take an immediate and serious deep dive into guaranteeing commercial cargoes for U.S.-flag carriers. This is not a new idea, but one worth revisiting. This proposal, if enforced by treaty or legislation, would have negligible impact on shippers while significantly improving the capacity and number of both the U.S.-flag fleet and U.S.-mariners.

Domestic Shipbuilding Capacity

The United States’ sealift fleet has received limited Congressional attention over decades of continued use. New construction and conversion of Maritime Prepositioning Ships and the development of large medium speed roll-on/roll-off vessels achieved successful results, but the alignment of sealift ships under a 30-year shipbuilding plan has never materialized. Most recently, the Navy’s 30- year shipbuilding plan and the SECNAV’s Sealift that the Nation Needs (STNN) report to Congress (2018) considered sealift vessels or auxiliary vessels.

However, its vessel proposals are not in sufficient numbers and the timeline described to achieve increased readiness and availability is not effective. Sealift vessels generally fall into 10-15 year shipbuilding periods, with long lapses between programs that can exceed 10 or even 20-years. These aging vessels are often managed with decreasing levels of resourcing over time, despite the increasing need. The greatest shortfall in plans for a viable sealift fleet involves short-term programs of 20-25 years or less, for a fleet intended to last 50 or even 60-years.

The sealift fleet includes both commercially-operated vessels, in-service, as well as organic sealift vessels, many of which were former commercial vessels or built to rigorous commercial classification society standards. Both the United States government and the shipbuilding industry would benefit from a shipbuilding plan that identifies ship construction opportunities over a 20–30-year timeframe.

  • The Navy’s existing Long-range (30-year) Shipbuilding Plan narrowly focuses on Combatant and Auxiliary vessels; leaving sealift vessels for ad-hoc recapitalization strategies.

Acquisition and modernization of ships for defense agencies has been successfully executed since 1976. Capital improvements were executed through the modernization of Joint Logistics over the Shore (JLOTS), Offshore Petroleum Discharge System (OPDS), and an intentional shift from breakbulk cargo to roll-on/roll-off vessels. Staying current with modern technology, MARAD was forced to continually upgrade the organic fleet to deliver increased sealift capacity to meet the demand signal from USTC. Today, the STNN report outlines a path that provides limited resourcing of ships on a progressive, but low-accession rate. Newer ships, ships built today and those available for procurement do not match ships built 30-40 years ago in terms of structural arrangement (scantlings) or suitability for laid-up status – both of which are important considerations for strategic sealift.

Shipbuilding Plan

MARAD has proposed development of a long-term, planned sealift shipbuilding initiative that focuses on commercially-developed but militarily useful ships. The greatest gap in shipbuilding is the difficulty in constructing ships usable for commercial purposes that could also be useful as naval auxiliaries in time of war or national emergency. By developing a shipbuilding plan, MARAD seeks to coordinate with commercial ship owners, whereby the government invests a reasonable or an agreed upon portion of the cost at new construction for any vessel, and after operation for a period of ten years commercial service, accepts the vessel into the organic sealift fleet for an additional 20-25 years. By offsetting the initial, up-front costs for ship owners, and including national defense features in construction, MARAD would recapture a stake in the efficient construction and operation of a U.S. flag vessel. Participation would come with conditions including periodic inspection, equipment validation, modernization upgrades, and other program involvement as well as full Voluntary Intermodal Sealift Agreement (VISA)/Maritime Security Program (MSP) enrollment. This initiative works in conjunction with all other sealift programs to ensure a continuing supply of modern, U.S.-built ships for procurement for defense needs.

At scale, this plan could include the construction of four ships per year for ten years, for acceptance by the Government after ten years. The 4/10/20 plan involves initial investment by the Government, paired with industry financing to build U.S. flag ships in domestic shipyards. This accession rate exceeds the rate of the STNN report, decreases the average age of the commercial / organic sealift fleets, and reduces a reliance on foreign-built ships for defense purposes. Most importantly, this plan provides a predictable timeline of ship construction options at a rate of four ships per year. Because the government pays their share up front, concerns of subsidies can be avoided, and it combines both government funding and private financing for greater effect in the shipyard industrial base.

MARAD’s key focus areas for domestic shipbuilding capacity include:

  • Continuation and expansion with reduced barriers of application and award of the Title XI financing.
  • Development of a sealift plan that parallels Navy’s 30-year Shipbuilding Plan and provides insight to optioned ships (4/10/20 Plan)
  • Continued effort to align all non-combatant, national shipbuilding needs through the Government Shipbuilders Council (GSC-V)
  • Revision of the National Defense Features and Sealift Enhancement Features catalogues for outfitting on any U.S. flag ship
  • Availability of other sealift programs, including procurement for NDRF, Ship Disposal Programs, etc.

Single Sealift Manager

The nation’s sealift capacity exists in multiple organizations with potential shortfalls as these ships age and competition for resources does not match organizational objectives. Through multiple ship repair contracts of existing ships, both the MARAD and Military Sealift Command (MSC) compete for available dry-docks in an increasingly difficult regulatory environment. With ship repair availabilities taking longer, ships and their programs must choose to prioritize based upon the urgency of the ship’s required performance, e.g. prepositioning, and the regulatory requirements of American Bureau of Shipping and the U.S. Coast Guard. Aligning sealift capacity to one single manager could alleviate congestion and give greater insight to shipyards seeking work on up to 61 ships.

Reroute Ad Valorem Tax Funds

Domestic shipyard availability, increasingly longer and more complex repairs, and skilled worker shortfalls means that repairs in foreign shipyards may be more desirable or simply necessary due to availability and skilled labor pools that combine to meet an approved ship repair availability timeline. Today, MSC ships and even MARAD’s RRF ships still face 50% Ad Valorem taxes for repairs made overseas.2 The benefit of this tax is not gained by the industry, as the intent of the tax is meant, because it reverts only to the Department of the Treasury. Moving into a period of necessary ship construction revitalization, MARAD has proposed that the Ad Valorem tax be revised to fund activities that directly benefit domestic shipyards, through funds applied for increased infrastructure improvements, cybersecurity and industrial security, sill dredging, and skilled worker recruitment and training. By applying Ad Valorem funds directly, this initiative could be executed like the Small Shipyard Grant Program, through a validation process recorded and assessed by MARAD.

MARAD’s key focus areas for redirecting Ad Valorem funds to domestic shipyards include:

  • Select infrastructure improvements and modernization
  • Cybersecurity and industrial security measures
  • “Last mile” graving dock and floating dry-dock area sill dredging
  • Skilled worker recruitment, training, and apprenticeship programs

There are many factors to take into consideration in the rapid decline of the shipbuilding industry, including global oversupply, recessions and changing economic fundamentals, but one policy decision clearly stands out. For decades, countries around the world have subsidized their national shipbuilding industries. Up until 1981, the U.S. followed suite through the payments of construction differential subsides (CDS). As soon as foreign shipbuilding companies gained the advantage of subsidization from their governments, subsidization for U.S. shipbuilding went in the opposite direction leaving the U.S. industries at a disadvantage and unable to compete for business.

Currently, the U.S. ranks 19th in the world for commercial shipbuilding, accounting for approximately 0.35% of global new construction, which is a mere one-third of one percent of new commercial shipbuilding occurs in the United States, despite having the world’s largest economy.3 In the absence of any U.S government action to enforce fair market participation, the commercial shipbuilding industry almost immediately began to suffer a steady decline and struggled to remain competitive against foreign subsidization. The impact of these trends is evidently clear. South Korea has 37% of global shipbuilding, Japan has 27% and China has 21%.4 South Korea alone is building more than 100 times the number of ships as the United States.

Maritime Security Program

Military, congressional, and other government leaders noted that while MARAD’s RRF offered an effective and rapid source of ships for strategic deployment, even the RRF and the sealift capabilities of Military Sealift Command together could not sustain a serious and prolonged U.S. military deployment overseas. Additional support from a commercial U.S.-flag merchant marine is essential for strategic sealift requirements, as was proven in all American wars of the twentieth century, including Operations DESERT SHIELD and DESERT STORM. Accordingly, in 1996, Congress passed and the president signed the Maritime Security Act of 1996 (MSA), which established the Maritime Security Program (MSP).

The Maritime Security Program (MSP) maintains a fleet of 60 modern, privately-owned U.S.-flag ships, active in international commercial trade, yet available on-call to meet U.S. Department of Defense (DOD) contingency requirements during war and national emergencies. The MSP ensures a minimal but vital role for the U.S. in global sea trade, while employing some 2,400 of the trained, skilled U.S.-citizen Merchant Mariners needed to man the Government-owned surge fleet in times of crisis.

The current MSP fleet includes 23 container ships, 11 geared container ships, 18 roll-on/roll-off (RO/RO) vessels, six multi-purpose/heavy-lift ships, and two tankers. The cargo capacity of the MSP fleet, now exceeding 3.4 million sq. ft., is at the highest level in the program’s history, including some 117,000 TEUs, 3.16M sq.ft. of RO/RO capacity, 335,659 sq.ft. of heavy-lift capacity, and nearly 667,000 bbl. of fuel transport capacity.

Cargo Preference

Cargo preference statutes are crucial to U.S.-flag vessels and American commercial sealift. Currently, DoD cargoes are contracted through USTC, either by Surface Deployment & Distribution Command (SDDC) or MSC for full ship charters. However, a large portion of other government cargoes are shipped by various other agencies. Centralizing the contracting of all government impelled cargoes under USTC could effectively and efficiently reduce cost, increase visibility, increase cargo preference adherence, and strengthen national strategic sealift capability. USTC has the robust transportation in place to support this centralization.5

Sealift Recapitalization

In an effort to increase the RO/RO capacity through the MSP, scenario comparisons were made to show a generic time line and cost to reach USTC requirement for sealift square footage. To start, data of the notional Army unit types was used to calculate the number of vessels of each class to carry a full complement, Table 1.

Next, three scenarios were created, with assumed variables, how much it would cost and how long it would take to bring American strategic sealift within mission readiness standards set by USTC.

Scenario #1: Emphasis on a new construction program with new Commercial off the Shelf (COTS) RO/RO vessels replacing Large Medium Speed RO/RO (LMSR)’s currently in the afloat prepositioning fleet, and shifting to surge. Estimated time to meet USTC mission readiness is 12 years.

Scenario #2: Double the commercial MSP fleet of RO/RO vessels and limiting the number of new COTS RO/RO vessels to analyze the commercial increase option. Fewer new vessels will be constructed leaving funding for purchasing used commercial RO/RO’s in the open market. Estimated time to meet USTC mission readiness is 7 years.

Scenario #3: Same as Scenario #1 with the exception of restricting the time limit met in Scenario #2 of 7 years. This scenario fails the square footage requirement to meet USTC mission readiness.

Scenario 1 Summary

Case maintains a status quo of 18 MSP RO/RO vessels in the fleet with 50 U.S. new construction incorporating commercial build specifications with national defense features and complying with the Jones Act. The time to meet the TRANSCOM requirement of 19.6 million sq.ft. is 12 years at $3.0B per year for a total cost of $37.0B. Factors in the estimate include an average attrition of 17% for shipyard availability, general repairs and maintenance. Average cost for a new U.S. built COTS vessel is estimated at $280M per ship with 4 new vessels planned per year. Purchasing used foreign RO/RO’s is estimated at $84M per ship with approval to purchase up to 9 off the open global market. Estimates do not include rate of which ships are removed from service and either scrapped or placed into the NDRF.

Scenario 2: 36 MSP RO/RO Vessels w/ 29 New Build & 9 Used Foreign (7-year period)

Scenario 2 Summary

Case doubles the MSP RO/RO fleet to 36 vessels in the fleet with 29 U.S. new construction incorporating commercial build specifications with national defense features and complying with the Jones Act. The time to meet the TRANSCOM requirement of 19.6 million sq.ft. is 7 years at $3.0B per year for a total cost of $22.2B. Factors in the estimate include average attrition of 17% for shipyard availability, general repairs and maintenance. Average cost for a new U.S. built COTS vessel is estimated at $280M per ship with 4 new vessels planned per year. Purchasing used foreign RO/RO’s is estimated at $84M per ship with approval to purchase up to 9 off the open global market. Estimates do not include rate of which ships are removed from service and either scrapped or placed into the NDRF.

*** Notable savings with Scenario #2. Fleet restored to 85% mission readiness, which includes a 17% attrition, 40% of the time and 41% savings. ***

Scenario 3: 18 MSP RO/RO Vessels w/ 28 New Build & 9 Used Foreign (7-year period)

(Click to Expand)

Scenario 3 Summary

Case maintains a status quo of 18 MSP RO/RO vessels in the fleet with 28 U.S. new construction incorporating commercial build specifications with national defense features and complying with the Jones Act. This scenario fails to meet the TRANSCOM requirement of 19.6 million sq.ft. at the 7-year mark with a delta of 16.8%. With 17% attrition for shipyard availability, general repairs and maintenance, mission readiness fails to meet at 83%. All variables and assumptions were the same applied to Scenario 1 and 2.

Potentially increasing the MSP fleet size, MARAD’s selection criteria for new ships entering the current MSP fleet reflect DoD’s stated priority preferences by vessel type. With the priority emphasized on RO/RO’s, replacements are already under an MSP Operating Agreement tend to be the same types as those being replaced. Two key benefits of increasing the MSP RO/RO fleet, they are instantly mission capable and operationally ready for service.

There are inherit risks to increasing the MSP. Some of these capabilities can never be fully replaced without construction or modifications. However, vessels of the U.S. flag commercial fleet can be purchased and modified to replace some Ready Reserve Force/MSC assets, as provided for in the U.S. Navy’s current surge fleet recapitalization planning. For political or economic reasons, the U.S. military could find itself in a situation in which foreign-flag shipping is not an option to support U.S. military operations.

For instance, due to prior circumstances of particular conflicts, flag states may refuse to permit their vessels to enter a war zone so as not to offend an ally or related business interest or operators do not wish to charter vessels to the U.S. military because they could potentially lose market share from their regular, existing customer base and trade routes. From a foreign operator’s perspective, carrying U.S. military cargoes, even at premium rates, may be a poor business decision in the long term, which may discourage foreign-flag owners and operators from even considering such an option.

New Cargo to Maintain the Commercial Sealift Fleet

In the 1970s the United States negotiated a bilateral agreement with Brazil reserving 40% of each country’s exports for the merchant fleet of each trading partner and the remaining 20% was available for third country fleets. Shortly thereafter the United States negotiated a similar bilateral agreement with Argentina. These agreements gained the interest of many developing nations and thus the “40/40/20” became a new standard adopted by the United Nations Conference on Trade and Development (UNCTAD) Code of Conduct for Liner Conferences. The UNCTAD Code came into force on October 6, 1983, six months after its ratification. However, the United States never ratified the Code even though the U.S.-carriers and the U.S.-maritime unions were supportive. The UNCTAD 40/40/20 was designed around the ocean shipping conferences that dominated ocean liner trade in the 1970s. Subsequently over the following decades, due to changing political environments, conferences have become unlawful in some parts of the world and are now practically non-existent. However, during this same period, carriers have developed operational conferences or cooperation in the form of vessel sharing agreements (VSAs), also referred to as liner consortia.6

Strategic Sealift Officers

Strategic sealift is essential to the U.S. Navy’s ability to carry out its sea control, power projection, and maritime security missions—and essential to strategic sealift is a cadre of Navy Reserve officers who provide emergency crewing and shore-side support for the Military Sealift Command’s Surge Sealift Fleet and the Ready Reserve Force in times of national defense or emergency.

Strategic sealift officers (SSOs) today have two priority missions: to provide strategic depth as tactically trained, experienced, and credentialed licensed mariners; and to deploy operational capability through their subject matter expertise in marine engineering, operations, and logistics and ties with the maritime ecosystem.

This diverse maritime expertise is a force multiplier. The broad educational backgrounds, world- wide employment and specialties in work experience enable these dedicated mariners to apply critical skills and non-traditional methods to overcome current and future obstacles. Members will use their unique maritime industry understanding, training, and proficiencies in support of U.S. Navy and national-level requirements.

Years of specialized training and education are required to earn and maintain the U.S. Coast Guard Merchant Marine license and associated additional credentialing by the International Maritime Organization (IMO). The U.S. Merchant Marine must continue to attract, retain, and promote top talent from the nation’s maritime academies. This workforce is the key enabler to accomplish a vital mission.

Concepts of Maritime Solutions

Strengthen the Maritime Industrial and Innovation Base. Reinvigorate and promote a competitive modern maritime industrial and innovation base. Leverage commercial leading-edge suppliers to provide a strong and sustained competitive advantage within the global maritime commons.

Sustain the Forces. The Maritime Services should generate resilient and adaptable logistics to sustain forces globally in contested environments. Successful mission execution demands the planning, prioritization and modernization of U.S. flag strategic sealift capabilities, maritime prepositioning network forces, prepositioned forward munition stocks, warfighter provisioning, allied and coalition partner support coupled with distributed and agile logistics. Logistics investments needed include the Next Generation Logistics Ship – which could be a commercial-of-the-shelf (COTS) RO/RO vessel with NDRF capabilities, utilized to sustain afloat and ashore littoral forces and strategic sealift assets within the Ready Reserve Fleet – the Maritime Security Program, and a Tanker Security Program.

Develop Integrated Maritime Forces with fiscal resources allocated to the U.S. Navy, Marine Corps, Coast Guard and Merchant Marine by the U.S. Congress. Consistent and sufficient funding will support the strong maritime defense industrial base needed to deliver future naval and strategic sealift ships, aircraft, munitions and supplies. Steady resourcing will allow the Maritime Services to invest efficiently, provide accountability, preserve military advantages and enable consistent strategy execution in contested environments.

Address the Strategic Sealift Gap and Restore the U.S. Merchant Marine. Both a robust maritime industry and the policies that aim to support it are increasingly important in an era of great power competition (GPC). DoD mobilization requirements depend heavily on the U.S. flag commercial maritime industry. However, with now fewer than 90 vessels, this industry continues to face mounting pressures ranging from fragmented and ineffective policies to highly subsidized foreign maritime assets that undermine its long-term viability, its ability to innovate, and its capacity to support future military operations. To effectively compete, the U.S. must break with a long-standing approach that assumes the commercial and military requirements of the maritime industry are the largely distinct. Instead, the U.S. must adopt an integrated approach that recognizes the inherent interdependence between the two and foster a healthier commercial maritime industry that can effectively support DoD force mobilizations. In just one example, American shipyards require modernization through capital improvements, infusion of more efficient processes and a skilled workforce to fully realize increased capacity and capability. To address this, the development of a long-term, planned shipbuilding and repair initiative that focuses on commercially-developed, but militarily useful ships would inevitability help close the gap in shipbuilding. Without a “leveling” of the playing field for commercial shipyards through some form of construction subsidy, tax incentives, or long- term government shipbuilding program, U.S. shipyards will be unable to construct large commercial vessels at a cost more competitive with heavily-subsidized foreign (primarily Asian) shipyards.

This plan would provide insight and predictability to shipbuilders and an opportunity to construct ships for U.S. flag carriers. MARAD would provide stability where boom-and-bust cycles of episodic sealift shipbuilding has been the norm by supporting a shipbuilding plan in coordination with commercial ship owners, whereby the government invests a significant portion of the cost at new construction for any vessel and after operation for a period of ten years commercial service, accepts the vessel into the organic sealift fleet for an additional 20-25 years.

By offsetting initial, up-front costs for ship owners and by including National Defense features in the construction, MARAD would reclaim stake in the efficient construction and operation of U.S. flag sealift vessels. Participation could come with conditions, including periodic inspections, equipment validation, modernization upgrades and other program involvement as well as full MSP/VISA enrollment. While not excluding Jones Act ships, this initiative would work in conjunction with all other sealift programs to ensure a continuing supply of modern, U.S. built ships in support of an effective military mobilization.


The United States is already emerging from a period of strategic atrophy. American competitive military advantage is rapidly waning. With increased global disorder characterized by the decline in international order, the global security environment is becoming far more complex and volatile than any of us have experienced in recent memory.7 The time is now to recognize and commit to a new and comprehensive National Maritime/Defense Strategy to rebuild America’s merchant marine.

The commercial U.S. shipbuilding and repair industry today exists solely on work provided by government contracts and Jones Act construction and repair work. Absent the Jones Act, virtually all remaining large shipyards would be forced out of business, with a negative ripple effect on the supporting supply chain. U.S. shipyards need some combination of subsidies, stimulus, and predictable demand to compete with foreign shipyards that enjoy all of those advantages. American yards require modernization through capital improvements, infusion of more efficient processes, and a skilled workforce to fully realize increased capacity and capability. Those investments are not likely without external assistance.

Ways of promoting the U.S. Merchant Marine and substantially increasing the number of U.S.-flag ships in international trade are available. First, negotiate bilateral agreements with the major United States trading partners like the Brazilian bilateral agreement of the 1970s construct. The agreements may be constructed around the new Vessel Sharing Agreements and with higher levels of third country participation. Bilateral agreements may be prioritized with other countries based on data as a trading partner with the United States. As opposed to 40/40/20 the agreements could be more reasonably negotiated as 10/10/80 agreements. This should increase U.S.-flag participation in U.S.-trade twofold from the current 2% to 4% and beyond in support of American national security and economic prosperity.8 Second, provide additional tax incentives to U.S. carriers, perhaps along with shipper tax incentives. Existing laws and regulations that discourage operators from flagging their ships in the United States could be revised. None of these efforts would require additional appropriations. As far as tax incentives are concerned, the U.S. Treasury is not currently benefiting from foreign-flag operators paying taxes, so having similar tax breaks for a larger number of U.S.-flag operators would have no significant impact on tax revenues.9 First and foremost, the United States should focus on meeting the requirement for strategic sealift capacity.

Leveraging the commercial employment of SSO members the Navy will strengthen strategic relationships with the maritime industry. Industry partners provide complementary capabilities, unique perspectives and information that improves collective understanding of the operating environment and expands options. Correspondingly, strategic sealift officer experiences within the maritime ecosystem enable rapid identification and development opportunities to apply commercial best practices to more efficiently use resources and optimize operations. Mutually beneficial partnerships within the maritime ecosystem are crucial to national strategy. By being an integral part of the maritime ecosystem and the Navy, the SSO force supports successful naval operations and helps strengthen the preeminence of America as a maritime nation.

The Merchant Marine through Strategic Sealift provides the Nation’s “fourth arm of defense” and has historically organized, trained, and equipped to perform three essential functions: sea control, power projection, and maritime security. Curiously, it was an American, Alfred T. Mahan, who dramatically energized global powers, including, eventually, the United States, about the critical importance of commercial flag-state merchant shipping and accompanying naval power.

Contrary to the term that “size matters”, sealift forces do not need another fleet of 250,000 square-foot capacity LMSR’s. They do need ships that are commercially viable for Jones Act and international trade and that have national defense capabilities incorporated in the early stages of construction and built to commercial off-the-shelf (COTS) specifications. Naval warship design technology is not applicable with strategic sealift vessels. Stick to the basics with the USTC 24-10 specification Appendix A for strategic sealift, not what the Navy assumes it needs for strategic sealift. Coincidently, RO/RO’s are built with similar USTC 24-10 specifications incorporated into the construction with ample deck strength on the permanent decks and clear overhead heights complying with basic sealift requirements.

U.S. strategic sealift needs to be both commercially and military viable, to serve dual purposes for the economic and national security interests. The fleet of strategic sealift vessels will serve no purpose sitting pier side in the U.S. waiting for the next conflict to arise. Ships need to be underway, making way and earning money for companies that have employed those vessels and U.S. merchant mariners.

Since World War II, the U.S. fleet has matured and withered to the laws of supply and demand due to the strength of foreign competition. As a nation, the United States have never let the fleet get too small without performing ambitious analyses in recapitalization or through creative means of subsidies and exclusive contracts.10 Through persuasive realignment of U.S. government policy and legislation that incentivizes the U.S. fleet to become globally competitive would be the fundamental basic principles of reviving a viable Strategic Sealift for the United States and allowing USTRANSCOM to successfully execute and accomplish worldwide operations that strengthen national security and directly contribute to achieving the nation’s objectives.

The logistical side to the US Pivot to the Pacific. One of the aspects not often discussed of the US “Pivot to the Pacific” is that it is not just combat forces (US Army, US Air Force, US Navy and US Marine Corps) moving, but also the Military Sealift Command, which constitutes the cornerstone of logistical support for US operations all over the world. Just to get an idea of its size, if this command’s ships belonged to another nation they would be the fourth-largest navy in the world. As a consequence, NATO European members must reinforce their logistical capabilities.

The best-prepared naval forces to achieve this are the Royal Navy (the Royal Fleet Auxiliary, to be more precise) and France’s Marine Nationale. Germany is beginning to boost her global-scale force projection capabilities, limited to date due to well-known historical reasons. Now, the economic crisis and ensuing budget cuts are providing added impetus to the development of shared capabilities. While there is a growing pressing to achieve this, it is nothing new. For example, we can mention the United Kingdom and the Netherlands as a model of force integration, with their UK/NL Landing Force. By the way, there is a Catalan angle to this. Anglo-Dutch cooperation in amphibious operations dates back to the 1704 landing in Gibraltar, where a 350-strong Catalan battalion under General Bassett also took part. Therefore, should a future Catalan contingent join the UK/NL Landing Force, they would just be coming back home. Another significant example are the three Baltic Republics, which combine their naval forces in the BALTRON (Baltic Naval Squadron).

Barcelona and Tarragona Harbours: two key dual-use infrastructurs in the Western Mediterranean. When we talk logistics, one of its key elements are ports. It is precisely when countries are pondering how to cut costs that the concept of dual-use infrastructures comes to the fore. In this area, the ports of Barcelona and Tarragona can make a much greater contribution that they do at present. Right now, other than the occasional port visit by the US and other Allied navies, they are not the permanent home of any Spanish Navy unit. Furthermore, despite healthy growth in terms of tonnage, much of their necessary connecting infrastructure remains incomplete. In particular, a European gauge connection to the French railway network. However, in addition to featuring in plans for a future Catalan Navy, they could also become an strategic asset for NATO, being home to a portion of the Atlantic Alliance’s logistical units in the Mediterranean Theatre.

It is not just a matter of size. Both infrastructures are located in areas sporting a concentration of industry and transportation links. These links must certainly be improved, in line with the EU’s 2013 decision to confirm the “Mediterranean Corridor” as a key element of the Old Continent’s transportation networks. This label refers to a railroad transportation axis connecting cities and ports along the Spanish southern and eastern seaboards to France. Since most EU member states also belong to NATO, there is no reason to expect any discrepancy between the two organizations when it comes to the logistical map of Europe.

The benefits on the civilian economic front of completing this infrastructure have already been explained at length by myriad economists, such as for example Ramon Tremosa, currently serving as member of the European Parliament, who has written extensively on the project and worked hard as a lawmaker to see it come to fruition. This explains the support of the French Government and the European Commission, which have rejected alternative proposals to drill a tunnel in the Central Pyrenees, connecting Spain and France through the Aragon region. From a naval logistics perspective, this alternative plan would not have benefited NATO and allied navies to the same extent, since it would have meant bypassing Tarragona and Barcelona. The benefits of the “Mediterranean Corridor”, on the other hand, also extend to the field of defense. For example, should NATO’s Response Force (NRF) need to project one of its battle groups in a crisis scenario, we may ask ourselves whether Toulon, Marseilles, and Naples harbors would suffice. While it would not be impossible, it may make it harder to label it a rapid-reaction force.

Tarragona Harbor

The Pivot to the Pacific rests on a strong NATO and a secure Mediterranean. The US Pivot to the Pacific, and more widely the growing coordination among the maritime democracies in the Indian-Pacific Ocean Region, are based on the assumption that the Mediterranean will be secured by NATO. Thus, any move reinforcing security in this body of water has a direct, positive, impact on the struggle for the rule of law at sea in the Indian-Pacific Region. A struggle, let us be realistic about it, that is surely to be bitterly tested in the future ahead. As a historical reminder of the connection between the two regions, we may mention the failed British strategy to defend Singapore. Built at a time of scarce resources, the naval base was supposed to provide the necessary facilities for a strong naval and air force to be moved in the event of a crisis, without the expense involved in a permanent presence. However, the need to protect home waters, the Atlantic, and the Mediterranean, meant that all that London could send were HMS Prince of Wales and HMS Repulse, sunk by Japanese land-based naval aircraft in the South China Sea in the opening days of the Second World War in the Pacific.

Conclusions. Barcelona and Tarragona are key dual-use facilities in the Western Mediterranean, whose naval logistical potential to date has not been fully exploited. Their worth will multiply once the “Mediterranean Corridor”, backed by Paris and Brussels, is completed. Their potential contribution to NATO is growing as pressure on defense budgets forces countries to get as much bang for the buck as possible, and as moves to reinforce the Indian-Pacific Ocean Region make it imperative to fully secure the Mediterranean.
