The LCS Survivability Debate

There has been a lot of discussion lately about the survivability of the LCS and smaller combatants in general. A recent US Naval Institute News opinion piece contends,

“Small warships are historically unsurvivable in combat. They have a shorter floodable length, reduced reserve buoyancy and are more likely to be affected by fire and smoke damage than larger combatants. In both World Wars, losses in ships below 3000 tons in displacement far exceeded those of larger vessels.

“In World War II, for example, the U.S. lost a total of 71 destroyers and 11 destroyer escorts — all under 3400 tons displacement and less than 400 feet in length.

“By comparison, only 23 larger ships were lost. Part of that figure is undoubtedly due to their operational employment, but in simple terms of engineering and physics, larger ships are inherently more survivable than their smaller counterparts.”

In the Coast Guard we once had a saying, “In our obscurity is our security.” I think that should be kept in mind when we consider the survivability of small surface combatants. No, they cannot take as much damage as major surface combatants, but the enemy gets a vote, and he will be less “excited” by the presence of smaller vessels, while he will normally choose to put more effort into destroying larger, more threatening ships. As in land warfare, tanks are more survivable than infantrymen, but they don’t necessarily last longer.

To look at how this factor might influence survivability, I looked at how many of the ships that were in commission at the beginning of World War II were sunk as a result of enemy action. My source is the Summary of War Damage to U.S. Battleships, Carriers, Cruisers, Destroyers, and Destroyer Escorts which is accessible here. The figures there do not correspond to those quoted above, rather they report 58 destroyers and 9 destroyer escorts sunk, along with 26 larger surface combatants, all listed by name. (The USNI post may have included constructive losses that were not actually sunk or losses to other than enemy action, and does not include the three battleships salvaged although they were out of action most of the war.)

If we look only at the US fleet at the beginning of the war, it included 233 major surface combatants of which 46 or 19.7% were sunk by enemy action during the course of the war. If we break it down by class it looks like this:

Type: Number in Commission, Dec. 7, 1941/Number sunk/% lost to enemy action
Aircraft Carriers (CV): 7/4/57.1%
Escort Carrier (CVE): 1/0/0%
Battleships (BB): 17/5/29.4% (of the 5 sunk, all were at Pearl Harbor, 3 were salvaged)
Heavy Cruisers (CA): 18/7/38.9%
Light Cruisers (CL): 19/1/5.3%
Destroyers (DD): 171/29/17%

(There were no Destroyer Escorts in commission at the beginning of the war.)

If we lump  all the cruisers together, 8 of 37 were lost or 21.6%

If we lump the lone escort carrier together with the fleet carriers then four of eight were sunk or 50%

Additionally three destroyers were lost to weather in a hurricane. They were not ballasted properly, because of the exigencies of impending combat operations.

Clearly, at least looking at the World War II experience, the US Navy did not lose a higher percentage of smaller ships. If anything it appears the opposite is true. A smaller percentage of smaller ships were lost (17% vs 27.4%). More small ships were lost simply because there were many more of them. Undoubtedly some of the DDs and DEs that were sunk, would have survived the damage they received, if they had been bigger, but presumably there would also have been fewer of them. If the decision criteria were an equal chance of being sunk, then probably taking greater risk with smaller ships is both reasonable and unavoidable.

I will note that the probability of personnel loss on small ships is probably higher because they are more likely to sink quickly and catastrophically, while larger ships are more likely to sink slowly.

I will add a bit of anecdotal evidence. As part of Operation Overlord, the Normandy Invasion, 60 US Coast Guard 83 foot patrol boats were assigned to rescue those unlucky enough to find themselves in the water or sinking. 30 went to the American beachheads and 30 went to the British and Canadian beachheads. Being wooden hulled and gasoline powered, they certainly would not have been considered “survivable.”

Apparently they were in the thick of it, because they rescued 1438 men from the water and sinking craft. In spite of all the fire from shore, not a single boat was sunk and not a single crewmen was killed. Apparently the German gunners were too busy with the landing craft hitting the beach and the warships that were shelling them. They simply were not a priority target.

To Safeguard the Seas

The United States Navy is the most preeminent naval force in the world.  Following Alfred Mahan dictum that “a truly powerful nation must have thriving international trade, a merchant fleet to carry these goods and a strong navy to protect its sea lanes,” the U.S. Navy has provided stability, tranquility and maintained the global order since the end of World War II.   However, in this age of austerity, the ability of our aging fleet to secure our interests, protect our allies and confront our adversaries is being sorely tested.

As we paused in remembrance of the 73rd anniversary of the surprise attack on Pearl Harbor, Hawaii, by the Imperial forces of Japan, we again see a rising power in Asia bent on changing the status quo, increasing pressure on our allies and challenging America’s preeminence in the Pacific.

China’s assertiveness in the South China Sea over the past few years is significant as it “directly challenges America’s position as the primary maritime power in Asia and as the guardian of the old regional order,” said Hugh White.  As Ronald O’Rouke, specialist in Naval Affairs at the Congressional Research Service testified before Congress, he expects China “to continue putting pressure on its neighbors’ short of war in the East China and South China Seas to get its way in the region.”

It is clear our Navy is facing ever-increasing operational challenges, including not only air and sub-surface threats but also supersonic cruise missiles and ballistic missiles (both anti-ship and surface to surface).   Individually, these threats are difficult enough to combat, however, when encountered simultaneously; these threats severely challenge the current capabilities of our Navy.  With a rapidly expanding Chinese Navy, coupled with the increased pace of Russia’s ship building efforts, the pressure to do more with less compels us to develop new technologies to maintain the advantage if or when confrontations occur.

For the last 70 years, radar has played a key role in maintaining technological superiority over our adversaries.  Over the last decade, however, our radar capabilities have proved to be increasingly incapable of addressing existing and emerging threats.  This, in turn, directly impacts the Navy’s ability to assure maritime security and freedom of the seas.

Fortunately, the Pentagon has taken positive steps to rectify the situation by making investments in the next generation of radars.  The Air and Missile Defense S-Band Radar (AMDR) is an excellent example of advanced radar technology that will fill critical capability gaps and ensure our sailors can meet the ever changing demands of today’s global threat environment.

Designed to replace the ageing Aegis combat system currently employed in the fleet the AMDR is constructed as a self-contained radar that is scalable for any platform for any mission, with the ability to exponentially increase radar sensitivity.  Not only will the AMDR more accurately detect missile threats, but it will also help ships run more efficiently.  This new system reduces space, weight, power, and cooling demands of naval vessels, thereby maximizing the service life of the ships that incorporate this new technology.   These long-term cost savings make AMDR a wise use of limited taxpayer dollars in today’s austere budget environment.

With the ability to confront multiple threats simultaneously — even in the presence of heavy land, sea, and rain clutter — the technological advancement of the AMDR is truly remarkable. Scheduled to begin installation on the Arleigh Burke class destroyers’ starting in 2016 the AMDR is the technologically advanced, low-risk, cost-effective radar solution to combat today and tomorrow’s threats.

Tasked with the daunting challenge of maintaining freedom of the seas, deterring international aggression, and playing pivotal roles in times of war the U.S. Navy has earned naval supremacy, not only because of the skill of our sailors, but also because it has invested great effort and money to provide the finest technology in modern warfare.  This trend must continue with essential defense programs so that we may stay one step ahead of evolving threats.  Doing so will protect our national interests and ensure the safety of our sailors and war fighters. John F. Kennedy said it best, “Control of the seas means security. Control of the seas means peace. Control of the seas can mean victory. The United States must control the sea if it is to protect our security.”

Innovation Collaboration in Sunny San Diego

logoOn January 28th, the Athena Project and the U.S. Navy’s Space and Naval Warfare (SPAWAR) Systems Command Pacific (SSC PAC) [ed. Who doesn’t love nested acronyms?] will host the first-ever athenaTHINK event.  The day will include a design-thinking workshop to encourage collaboration between Sailors and scientists and teach structured brainstorming tools.  Open to all Sailors, you can sign up here. Over at our Athena Project site, Dr. Benjamin Migliori, a Navy researcher at SSC PAC, has more on the event:

Last year, we hosted warfighters from the USS Benfold at SSC PAC to foster better innovation, more inspired projects, and a better interface between Sailors and Scientists.  [Thursday], we’ll be doing that again.  Our purpose is to give warfighters and technologists a chance to work together in a design-thinking framework, and to open up the possibility of meaningful collaboration.

We’ll be giving Sailors an opportunity to see some of the bleeding edge work that we do here at SSC PAC, and giving the scientists a chance to hear real concerns from actual warfighters, rather than simply reading about them in briefs and training manuals.  We’ll be introducing the ideas of design-thinking for military applications, and showing that the civilian entrepreneurs don’t get to have all the fun.  We’ll be competing for a best project award – which could turn into much more and be the seed for a new initiative.

The Athena Project is an innovation-fueled initiative focused on providing a platform for Sailors to connect their great ideas with the scientists, engineers and academics that can help turn their visions into reality. Founded aboard USS BENFOLD (DDG 65) in early 2013, The Athena Project has hosted six Waterfront events in the San Diego area, as well as events in the Hampton Roads area and the Pacific Northwest. The basic premise is simple: Idea generation.  Sailors take a day off from their traditional duties to develop ideas to make the Navy or their command better – to scratch the creative itch and make solutions to their everyday challenges.

athenanw2On pitch day, Sailors are given have five minutes to present their concepts to an audience of their peers as well as innovation leaders in industry, government and academia. Following each presentation and question-and-answer session, the crowd votes on projects based on idea quality, actionability and presentation. At the end, the Admiral Sims Award for Intellectual Courage is presented to the highest score and the winner is granted command backing for a small functional team to develop their idea over the next quarter.  Previous winners have ranged anywhere from high-tech creative systems to low-tech solutions to common problems to innovative programs to make the Navy better.

The environment is casual and open, and sometimes takes the feeling of Shark Tank-meets-TED Talks, focused on building the creative confidence of the Fleet’s leaders of tomorrow. The vision of the project has always been to build a generation of Sailors that think differently, solve problems in unique ways and have the intellectual courage to stand up and do something about it.

As for the next pitch event, Waterfront Athena Seven? Well, that’ll be coming to a venue in San Diego in Late February. If you’re interested in presenting your big idea, connect with The Athena Project on Facebook or Twitter (@AthenaNavy) or just send an e-mail to athenanavy@gmail.com. If you’re interested in bringing an Athena Project event to your area, connect with the team!

The Brazilian Navy: Green Water or Blue?

Although much attention has been directed toward the uncertain fate of the Mistral-class amphibious assault ships that were being built in Saint-Nazaire, France for export to Russia, there has been considerably less reporting on Brazil’s quiet naval expansion. The Brazilian Navy has frequently been dubbed a ‘green-water’ force to distinguish it from conventional ‘blue-water’ or ‘brown-water’ navies. Whereas a blue-water navy is concerned with operations on the high seas and engaging in far-ranging expeditions, brown-water navies are geared toward patrolling the shallow waters of the coastline or riverine warfare. Green-water navies, however, mix both capabilities, focusing mainly on securing a country’s littorals but also retaining the ability to venture out into the deep waters of the oceans.

For several decades, this green-water label has been accurate to the Brazilian Navy. Although possessing a vast array of inland patrol ships and river troop transports to exert sovereignty over Brazil’s many rivers and drainage basins, the Brazilian Navy also boasts the BNS Sao Paulo, a Clemenceau-class aircraft carrier purchased from France in 2000. But there has recently been a shift in Brazil’s maritime priorities, suggesting that it may soon be more accurate to regard the Brazilian Navy as a blue-water force with some lingering vestiges of brown-water capabilities. Begun under Luiz Inacio Lula da Silva, President of Brazil from 2003 until 2011, and intensified under the Dilma Rouseff’s current government, Brazil has been on a shopping spree for military hardware. Although this has included procuring 36 Gripen NG multirole fighter aircraft from Saab for use by the Brazilian Air Force, much of the recent contracts have pertained to the purchase of vessels intended to modernize the Brazilian Navy. Brazil’s five Type 209 diesel-electric attack submarines, acquired from Howaldtswerke-Deutsche Werft, will be joined by four Scorpène-class diesel-electric attack submarines to be built domestically with completion of the first vessel expected in 2017.

In March 2013, Brazil’s President Dilma Rousseff inaugurated a domestic shipyard at which Brazil’s first nuclear-powered submarine – the fittingly named BNS Alvaro Alberto – will be built with French support. Delivery of the completed vessel is not expected until 2025 but the success of the project would bring Brazil into a very small club of countries with operational nuclear-powered submarines: the United States, United Kingdom, France, Russia, India, and China.S34 Tikuna

The Barroso-class corvette commissioned in late 2008 also seems to have inspired a new series of ships for the Brazilian Navy. The domestic shipbuilder Arsenal de Marinha do Rio de Janeiro has been contracted to build four vessels based on the design of the Barroso-class but with “stealth capabilities” and which will possess both anti-ship and anti-air armaments. Delivery of the first of these new stealth corvettes is expected in 2019 and as such many specific details about the design are currently unknown. Furthermore, delivery of two new Macaé-class offshore patrol vessels is expected in 2015, while an additional two will be delivered in 2016-2017, bringing Brazil’s fleet of these patrol vessels to seven in total.

But why is there this rapid buildup in maritime forces for Brazil? To some degree, these new procurement projects are intended to offset the Brazilian Navy’s diminished capabilities following the retirement of 21 vessels between 1996 and 2005. This would not explain the focus on vessels with longer-range expeditionary capabilities, though. Some observers may attribute the acquisition of ships with capabilities clearly not intended for the patrol of inland waterways, such as the new “stealth-capable” Barroso-class corvettes, to the threat posed by Guinea-Bissau’s instability. That Lusophone West African country, which has been dubbed a “narco-state”, has been a major hub in the international drug trade; Colombian cocaine often makes its way to Guinea-Bissau from the Brazilian coast, only to then be exported onward to Europe. But President José Mário Vaz, who was elected by a decisive margin to lead Guinea-Bissau in May 2014, has quickly moved to crackdown on corruption in the Bissau-Guinean military and seems set to make counter-trafficking a priority during his term in office. Even if Brazilian policymakers believe it may be necessary to exert a stronger presence in the South Atlantic to discourage narcotics trafficking, a nuclear-powered attack submarine is not at all the right tool for the task.

Rather, it seems most likely that there are two principal factors motivating Brazil’s naval procurement projects. With regard to BNS Alvaro Alberto and the potential acquisition of a second aircraft carrier, Brazil craves the prestige of at least appearing to be the leading maritime power in the Southern Hemisphere. Participation in major international maritime exercises, such as the IBSAMAR series conducted jointly with Indian and South African forces, are intended to promote a view of Brazil as a power that ought to be respected and consulted, particularly as Brazilian policymakers continue to pursue a permanent seat for their country on the United Nations Security Council. More importantly, however, the shipbuilding projects on which Brazil has embarked are intended to build up domestic industry and contribute to economic growth.

Brazil is already attracting considerable interest as a shipbuilder. In September 2014, the Angolan Navy placed an order for seven Macaé-class offshore patrol vessels, with four to be built at Brazilian shipyards. Over the past several years, Brazil has exported various vessels and equipment for use by the Namibian Navy. Equatorial Guinea has expressed its intent to acquire a Barroso-class corvette from Brazil for counter-piracy purposes. The A-29 Super Tucano, a turboprop aircraft intended for close air support and aerial reconnaissance, is produced by Brazilian manufacturer Embraer and has been exported for use in roughly a dozen national air forces. If Brazilian industry is successful in producing submarines and stealth corvettes, demand for Brazilian military hardware will only grow, generating impressive revenue and creating many jobs.

 Of concern, however, are Brazil’s long-term intentions with regard to the construction of BNS Alvaro Alberto. There are few navies in the world with the infrastructure and know-how necessary to successfully operate one or more aircraft carriers; after all, the club of those countries with aircraft carriers in service is limited to just nine. But the export of nuclear-powered attack submarines would undermine the international community’s non-proliferation treaty and could potentially harm international peace and stability. The Islamic Republic of Iran has been rumored to occasionally entertain plans to obtain a nuclear-powered submarine, while the Democratic People’s Republic of Korea has allegedly expressed a private interest in obtaining Soviet-era nuclear-powered submarines from the Russian Federation. This is not to say that Brazilian authorities would consider exporting such vessels to Iran, North Korea or other such regimes, but there is certainly a market for future submarines modelled on BNS Alvaro Alberto. It will be necessary to keep a very close eye on the Brazilian shipbuilding and nuclear industries in the 2030s, especially as domestic demand for this class of vessel is satisfied. 

To obtain a deeper understanding of Brazil’s long-term strategic goals and to perhaps exert some degree of influence over Brazilian arms exports, it would be advisable for NATO to seek a partnership with the country. In August 2013, a partnership was established between NATO and Colombia, demonstrating that the Alliance certainly is interested in security affairs in the South Atlantic. Brazil could also contribute much know-how to NATO members, especially as the Alliance attempts to find its place post-Afghanistan. Clearly, there is much work to be done in the area of trust-building if such a partnership is to be found prior to the expected completion of BNS Alvaro Alberto: as Colombian officials visited with NATO counterparts to discuss the partnership, Brazilian policymakers were among those Latin American figures who condemned Colombia for the initiative.

Partnering with Brazil will be very challenging diplomatically, but it is an effort that must be made. This rising power will soon find itself with a blue-water navy and, as such, military vessels flying the Brazilian ensign will become an increasingly frequent sight in the South Atlantic.
