Blockade: An Imperfect Strategy

By LT Jason Lancaster, USN

Introduction

Throughout history, maritime nations have used naval blockades to wreck the economies of their adversaries and bend them to their will. However, the impact of blockade in history has been overstated. Throughout history, blockade has been a part of military success, but it has never been the primary key to victory. Most successful blockades enabled land campaigns to succeed but would not have won wars on their own. Blockades are a politico-economic form of warfare that can quite often have unexpected political results. Modern calls to defeat China solely through an “easy and bloodless” naval blockade understate the physical difficulties and political challenges of a successful blockade, ignore that successful blockades support events ashore, and that blockades have not been successful as standalone campaigns.

Legal Definitions of Blockade

The San Remo Manual on International Law applicable to Armed Conflicts at Sea includes the requirements for a blockade. It must be announced, and all neutral and belligerent states should be notified of the blockade. It must be effectively maintained by a force as close as is required to be effective. It must not bar access to the ports and coast of a neutral state. It must be applied impartially to vessels of all states.

A blockade is not lawful if it has the sole purpose of starving the civilian population or denying it objects essential for survival, or the damage to the civilian population outweighs the military advantage of the blockade. The blockading belligerent shall allow the passage of medical supplies for the civilian population or for sick and wounded members of the armed forces.1 These requirements are designed to allow maritime states to conduct operations while minimizing the suffering of the civilian population of belligerents.

Quarantine is not a blockade. According to the Navy Commander’s Handbook on Operational Law, “the goal of quarantine is de-escalation and a return to the status quo ante.” The goal of a blockade is “denial and degradation of an enemy’s capability.”2

The British Blockade of Napoleonic and Revolutionary France

While some have argued that British blockades were the reason for victory over Napoleon, the blockades were not the root of victory. Even though they caused economic hardship it was not severe enough to force France to make a lasting peace. 20 years of blockade took its toll on cities like Bordeaux that relied on foreign trade and industries set up around imports like refining sugar, but the loss of such trade did not cause France to surrender. 20 years of bloody war from the Russian Steppes to the coast of Portugal caused the French empire to collapse after repeated military defeats ashore.  

From 1793 until 1802 and between 1804 and 1814, Great Britain conducted a close naval blockade of France and her allies. Throughout the wars of the 18th century Britain had refined the techniques and logistics of supporting a fleet on a hostile shore for sustained periods of time. Despite the idea that the primary purpose of the blockade was to strangle French commerce, the real purpose of the blockade was to prevent the French from invading Britain or Ireland. Despite the arduous blockade, the French twice managed to land forces in Britain and Ireland during the war. The blockade did limit the size and effectiveness of the landings. Humorously, the French invaders that landed at Fishguard, Wales surrendered to the local women who had come to look at the strange invaders.

Throughout the war, the close blockade of Brest was hotly debated. Was it better for ships to be beaten and battered off the stormy Biscay coast, or to maintain the fleet in port in expectation for the French to come out? Ships were lost in wrecks or damaged sufficiently to be sent back to British dockyards for repairs. These losses impacted the overall strength of the blockading force if the French did come out.3 Parallels can be drawn between the surface fleet today and the Royal Navy of 1805. The dockyards were full of ships desperately needing refit after years at sea, but the number of qualified dockyard workers had dwindled in both private and public dockyards. Shortages of skilled dockyard workers meant that new construction took longer than expected. HMS Royal Sovereign, Admiral Collingwood’s flagship at Trafalgar, was still in construction after 12 years, almost 3 years longer than normal for a first rate ship of the line.4    

The British blockade had an economic impact on Europe, but in some industries the impact was to preserve the traditional production method and delay the introduction of the new mechanized production methods used in Great Britain. The British blockade and the French Berlin Decrees banning trade between the continent and Great Britain certainly affected trade, but only seldom did it cause production to cease entirely. There were shortages of raw materials like cotton, but the cotton mills only went idle for a few months in 1808. The price was sometimes 2-4 times as high as that paid in Britain. From 1790 until 1810, French cotton consumption increased threefold while in Britain consumption increased fourfold.5

The blockade had unexpected political repercussions for Great Britain. The British blockade of France and her allies helped cause a war with Denmark in 1801 and the United States in 1812. Many ships from occupied places like the Netherlands ended up registering their vessels in neutral nations like Denmark and Sweden to continue trading. According to international law goods that were not contraband in neutral vessels could not be impeded. However, neutral goods such as hemp, pitch, tar, and pine logs were used to build and support naval vessels. Wheat was a neutral good but its dual use could make bread for the average French citizen or the citizen soldier. Britain argued that when the entire nation was in arms, was there a difference? Annoyed at British interference in their trade, Denmark, Sweden, Prussia, and Russia re-created the League of Armed Neutrality. Britain sent a fleet to Copenhagen, where Admiral Nelson fought a bloody battle with the Danes and persuaded them to surrender the remainder of the fleet. This combined with the death of Tsar Paul ended the League and its threat to the blockade.

In 1812, the United States declared war on Great Britain over the issues of free trade and Sailors’ rights. Many American citizens had either moved from Great Britain or could have been considered British subjects because of when they were born in America. The Royal Navy, perennially short of Sailors, impressed them from merchant ships. To a nation fighting for its life, often times alone, the nationality of a Sailor might matter little, especially since the British government believed that subjects could not change their nationality and had “an inalienable right to their service.”6 In 1807, the HMS Leopard stopped and searched the warship USS Chesapeake, a U.S. naval vessel for deserters, took four and hung one of them. It was a step too far. President Thomas Jefferson stated of the affair, “Never since the Battle of Lexington have I seen this country in such a state of exasperation as at present, and even that did not produce such unanimity.” While this incident did not cause the United States to go to war, it played a role following continued British harassment of American merchant ships.

From 1805-1813 the U.S. and Britain negotiated over the meaning of neutral shipping. Despite these negotiations, by 1806 120 U.S.-flagged vessels had been seized by the Royal Navy. The British position insisted that American vessels must carry non-American goods to an American port, unload them, pay duties, reload them, and then they were free to transship them to any country. The U.S. position was that as a neutral nation they had the right to ship any goods anywhere.7

In 1806, the U.S. also challenged British ideas of what constituted a blockaded port. American diplomats challenged the idea that the entire coastline could be blockaded by proclamation, but rather that warships had to create, “an evident danger in entering.”8 The U.S. Congress responded to British and French declarations of blockade against each other with an embargo on some British manufactured goods in the expectation that economic policy might force the British to accede to American demands.9 The twin wounds to trade and national honor through impressment eventually meant that the U.S. preferred to fight than continue to submit to such injustices.       

The British blockade hampered but never destroyed French trade. It made enemies of neutral nations, and did not expedite victory. Despite continued victory at sea, the Napoleonic Wars demonstrated that while a maritime power may contain a continental power, in total war a continental power must be defeated ashore.

Union Blockade of the Confederate States

Interestingly, if Britain would have acquiesced to American policy on blockade, then the Union blockade of the Confederacy may never have been legal. Despite the Union blockading the ports of the South, the Confederacy maintained open ports through almost the entire war. While the South suffered ever increasing shortages, blockade runners continued to supply the Confederate States and only the dominance of the northern armies compelled the South to capitulate.

The Union Navy began the war with 90 ships, including 40 steam vessels and 50 sailing ships. Not all of those ships were ready for war. Some were in the naval dockyards, some were stationed across the globe in California, the Mediterranean, Asia, and Brazil to protect tradeVessels stationed overseas would take up to six months to return to the U.S.10 At the outbreak of war, there were only three vessels ready for war on the Atlantic coast. It would take time for the Union Navy to marshal the forces required to conduct an effective blockade of a 3,500 mile coastline.

The Confederate and British governments did not believe that the Union Navy could successfully blockade the entire Confederate coast. However, the Union Blockade Strategy Board looked at the problem differently. Instead of worrying about the entire coastline, the Strategy Board broke the required blockade down to major ports with transport connections to the rest of the country. This drastically reduced the amount of coastline that required blockading. The Strategy Board utilized the United States Coast Survey’s records to examine the inlets, waterways, and ports of the South and decided that the primary ports of entry to blockade were Richmond, Norfolk, Wilmington, Charleston, Savannah, Mobile, New Orleans, and Galveston. The James and Elizabeth River channels leading to Richmond and Norfolk were blocked by Fortress Monroe and began the war well-blockaded. The remainder of the ports required blockading squadrons.

The initial organization of the Union blockading squadron consisted of one squadron blockading the Confederate coast from the Virginia Capes to Key West. This was later divided into North and South Atlantic Blockading Squadrons. The North Atlantic Blockading Squadron was responsible for the blockade between the Virginia Capes and the border between North and South Carolina. The South Atlantic Blockading Squadron was responsible for the blockade from the North and South Carolina border to Key West. In the Gulf of Mexico there was the Gulf Blockading Squadron which was also subdivided between east and west; the Eastern Blockading squadron watching the port of Mobile and the Western blockading squadron watching the port of Galveston and the Texas coast.

The Union blockade of Confederate states. (Mark A. Moore)

Ironically, the rights that the U.S. had gone to war with Great Britain over during the Napoleonic Wars were abandoned when the northern states declared their blockade of Confederate ports. The Trent affair almost brought Great Britain into the war against the north. In November 1861, two Confederate diplomats were traveling to London aboard a British flagged mail packet, the Trent. The ship was then forcibly stopped and searched by a Union frigate. Despite the protestations of the Trent’s captain, the two Confederate diplomats were taken into custody by the North and detained at Fort Warren, Massachusetts. The British government and press were outraged by the insult to their flag and international law. The two officials were released because the British government demanded their return and began some military preparations.11 

While the blockade grew ever more effective, it was never entirely effective. Throughout the second half of 1864 the port of Wilmington received 3.5 million pounds of meat, 1.5 million pounds of lead, 2 million pounds of saltpeter, 500,000 pairs of shoes, 300,000 blankets, 50,000 rifles, and 43 cannon. The Army of Northern Virginia and the Army of Tennessee received new uniforms and equipment.12 This does not mean that the blockade did not cause shortages amongst the population or the army, but that as an offensive strategy blockade alone would never defeat the South.

The only effective way the North closed Confederate ports was by physically capturing the port or destroying the fortifications and ships defending the port and occupying inland waters. Savannah was not captured until December 1864 when General Sherman took the city from the landward side. The South Atlantic Blockading Squadron had supported the northern army as it bombarded Fort Pulaski into submission. With the mouth of the Savannah River closed, Savannah lost its appeal as a blockade running destination. Likewise, the port of Mobile was not captured by Admiral Farragut; however his capture of Fort Morgan and the CSS Tennessee meant that blockade runners could not reach Mobile. Oftentimes, northern efforts to close a port simply shifted blockade running to another port. The Union offensive against Charleston in 1863 shifted blockade running to the port of Wilmington which because of the geography was even more difficult for the northern fleet to blockade than Charleston.

Blockading China

A blockade of China would be an immense undertaking. Chokepoints like the Malacca, Sunda, and Lombok Straits would all have to be guarded. However, the Law of the Sea recognizes a 200 NM Economic Exclusion Zone (EEZ). Neutral nations’ EEZ must be respected by combatant nations. To effectively police the chokepoints of maritime Asia, Malaysia and Indonesia would have to support the U.S. position. But neither of them are U.S. treaty allies and it is a major planning assumption that they would automatically support the U.S. side in a conflict. China would certainly exert great amounts of pressure on those states to remain neutral.

An average of 52 oil tankers transit the Malacca Strait a day, and the sheer number of possible boardings and prize crews could rapidly overwhelm the combat forces enforcing the blockade.13 A more effective means of blockading China would be a massive mining campaign. During World War II the British flew 20,000 minelaying sorties in the Atlantic Theater. These sorties sank 683 Axis ships while losing 450 aircraft. Only 150 Axis ships were sank by British surface and subsurface vessels. In 1945, the U.S. Army Air Corps helped isolate Japan from the rest of the world, starving Japan of resources.14 Despite the historical successes, the U.S. has not kept pace with the rapid technological changes in mine technology. Today, the bulk of U.S. mines are air-dropped, but the U.S. would have difficulty sewing air-dropped minefields in the face of the PLAAF and Chinese air defenses.

Conclusion

Throughout history blockade has been used as a strategy to deny adversaries foreign trade and prevent enemy warships from going to sea. However, neither blockade mentioned solely won the war. Troops ashore decisively defeated enemy armies and seized territory to win those wars. A “bloodless distant blockade” is not a magical panacea to bend China to U.S. will. A blockade of either country will stress U.S. resources to the limit and carries unknown diplomatic risks. It has not worked in the past, and will continue to fail as a standalone strategy in the future. It is an effective aid to victory, but no secret weapon.

Battle Force Missiles: The Measure of a Fleet

By Keith “Powder” Patton, CDR, USN

Calculating the power of a fleet is a daunting and imprecise task. In the Washington Naval Treaty, tonnage and gun caliber were used as metrics to set the ratio of capital ships between leading world navies. Capital ships were seen as the supreme arbiters of a naval conflict. The London Naval Treaty established similar rules for tonnage and gun caliber for smaller combatants. The United States Navy counts battle force ships, which includes combat logistics forces, toward its end strength. The battle force ship metric is simple hull count, with T-AKE, PC, LCS, DDG and CVN classes all being counted as equals, despite vastly different mission, size, manning, and capabilities. By a simple measure of hull count from 2018-2019 Jane’s Fighting Ships, the USN has 10 percent fewer warships than Russia, and is half the size of China’s fleet.

2019 Fleet total hull count by country.

However, when tonnage is used as the metric, the picture changes dramatically:

2019 Fleet total tonnage by country.

This change is unsurprising. The nature of the fleets are significantly different. The USN tends to operate much larger ships optimized for long range power projection. China and Russia have many missile-armed patrol boats and corvettes compared to the relatively few U.S. Cyclone class PC and corvette-like LCSs.

However, does the metric of tonnage truly measure the power of a fleet? The interwar period treaties considered both tonnage and caliber of guns. These two metrics were related, in that larger guns required a larger vessel to carry them. In general, there also was a direct correlation between the caliber of the gun and its destructive power.  Tonnage also affected how much armor could be carried to protect against gun hits. Another metric used to compare warship power was broadside throw weight. This was the total mass of shells a ship could deliver in a broadside against an adversary. A heavier broadside could be expected to triumph against less armed opponents. However, in the modern era, guns have been eclipsed by missiles as the primary weapon of naval combat. While battleships carried far more powerful weapons and were relatively immune to the deck guns of small combatants, the same is not true of missiles today.  Very similar if not identical anti-ship missiles are carried by small patrol combatants and mounted on the largest combatants, sometimes in identical quantities (eight being a popular number). While the defensive and damage control capabilities of larger vessels may be greater, it still seems likely that a few missile hits will knock most ships out of action, if not sink them. If missiles are the true measure of a fleet’s combat power, then neither tonnage nor hull count is an appropriate metric, because neither is directly related to a ship’s missile capabilities.

For the sake of this analysis, we will borrow Robert O. Work’s concept of battle force missiles (BFM) from his “To Take and Keep the Lead” monograph. BFMs are missiles that “contribute to battle force missions such as area and local air defense, anti-surface warfare, and anti-submarine warfare. Terminal defense SAMs, which protect only the host ship, are not considered a battle force missile.” Thus, weapons like RAM, ESSM, SA-N-9, Mistral, and HHQ-10 point defense SAMs would not count toward the tally of BFM. ASROC, Harpoon, Tomahawk, Standard Missiles and non-U.S. equivalents do count. Generally speaking, BFMs cannot be reloaded at sea, unlike shorter-range defensive missiles. They are too large and unwieldy. As such, they also serve as a cap on the offensive or defensive power a ship can provide. When BFMs are exhausted, the ship must return to a secure friendly port to rearm.

The ship numbers and missile capacity considered below were taken from Jane’s Fighting Ships 2018-2019 as a standard reference. In some cases, there are issues with overlap. For example, some U.S. Mk 41 VLS cells can carry a BFM, or quad-packed ESSM, which would not count. Russian vessels are able to fire SS-N-16 Starfish anti-submarine missiles from their torpedo tubes. While SS-N-16 (like ASROC) would count as a BFM, Jane’s did not have a magazine capacity of how many were carried by Russian warships. So, this BFM-launched via surface ship torpedo tube was ignored. Submarine heavy weight torpedoes were counted. While they may not be missiles, they are a primary anti-surface warfare weapon and, in some subs, are interchangeable with BFMs for strike or anti-ship missions. Finally, there was not complete data for all classes (e.g. number of torpedoes carried), so data was extrapolated from similar designs. The results of this BFM count are in the chart below.

2019 Battle force missile total by country.

This accounting of fleet firepower shows the USN has more than twice the BFM of the Chinese PLAN. The gap is even larger if the contribution of carrier-born aircraft is considered. The U.S. has an almost twenty-fold advantage in fixed-wing aircraft operating from ships. Carrier-born aircraft, especially from CATOBAR carriers, can carry multiple BFM and can reload aboard the carrier. In addition, the carrier can have its magazines reloaded at sea, something other ships cannot do with their BFMs. However, it is worth noting that China’s BFM count gained over 1000 missiles since 2017, and the U.S. number has been relatively static.

Using BFM as a fleet metric also allows for different ship sizes. A U.S. Flight IIA Burke class DDG with 96 VLS tubes provides the same BFM capacity as 12 patrol boats with 8 missiles each. Who would win in such an engagement would probably hinge on who had better intelligence, surveillance, and reconnaissance (ISR) support to target the other first. However, twelve patrol boats also have the advantage of being able to be in multiple places at once and needing at least 12 hits to defeat far more than the Burke could likely endure.  Continuing with Robert Work’s characterization, we can classify ships by their BFM count. Currently, warships have classifications of cruiser, destroyer, frigate, corvette or similar based more on politics than clear distinctions. What Work recommended was similar to the old system of classifying ships by guns. In this case, missiles instead of guns. First-rate warships (>100 BFM), second-rate (90-100 BFM), third-rate (60-89), and on down to unrated warships with negligible missile capability. For this analysis, the author augmented Work’s lower ratings with fourth-rate (40-59 BFM), fifth-rate (20-39 BFM), sixth-rate (6-19 BFM), and unrated as < 6 BFM. This reclassification produces the following fresh perspective:

2019 Warships by rating.

There is a clear USN preference for heavily armed surface combatants compared to potential adversaries. The one Russian Kirov is rated as a first-rate warship, but is barely a blip compared to the U.S. Ticonderoga-class cruisers. The Chinese Type 055 arriving into service will provide China with first-rate warships as well, but still a fraction of the number the USN has. The two U.S. Zumwalt DDGs in 2019 are third-rate ships-of-the-line, but have scores of better armed compatriots compared to the Chinese third-rate vessels. None have a fifth rate combatant (6-20 BFM) unless it is a submarine.

The chart above could spark concern at the rough parity in attack submarines between the U.S., Russia, and China. However, when broken down by type of submarine, the picture changes. The USN relies exclusively on nuclear-powered submarines to provide longer range, greater speed, and more submerged endurance compared to diesel or air-independent propulsion (AIP) submarines. This is because the U.S. plans an “away game” with submarines deployed far from U.S. shores, while Russia and China expect to be using their larger conventional submarine fleets close to home.

2019 Number of submarines by type per country.

When the metric of BFMs (including torpedoes) is applied, the U.S. is also shown to have a significant lead in subsurface firepower. While the U.S. has fewer SSGNs than Russia, they carry far more missiles per submarine. The three Seawolf SSNs also have an extra-large torpedo load, as do Los Angeles and Virginia class SSNs fitted with vertical launch tubes, to give them more weapons than other subs their size. This allows them to stay in the fight longer before returning to reload. Newer Virginia class submarines will have the Virginia Payload Module (VPM) installed, further increasing their firepower.

2019 Number of submarine weapons by country.

Of course, any single metric will fail to capture the power of a fleet. Informed opinions will differ on the correct offensive and defensive load mix for a warship, or the qualities of a Harpoon ASCM compared to a P-270 Moskit, 3M-54 Club, or YJ-18. Some of these issues are discussed by Alan Cummings in his 2016 Naval War College Review article on Chinese ASCMs in competitive control. In that article, he shows that for anti-ship firepower, U.S. surface vessels are severely over-matched. However, after 2016, VLS options for surface strike (SM-6 and Maritime Strike Tomahawk) have become feasible. Since the mixture of weapons in a VLS tube battery is variable, the number of cells may now provide a better metric than calculations assuming weapons loads. In addition, one must consider crew quality, training, and readiness as components of fleet power. National character and experience as a sea power also come into play. However, all of these qualities are hard to ascribe metrics to, and arms control treaties and analysts focus on measurable and verifiable metrics.

Conclusion

In the end, a fleet must be measured against what it is expected to do. For power projection abroad, a large number of BFMs (or carriers supporting strikes) would be more capable of performing the mission. Close to home, vessels can more easily return to friendly ports to rearm BFMs, so the total at sea may be less important. Even at equal numbers of BFMs, a fleet concentrating them on a smaller number of high-capacity platforms would be less able to control sea-space than a fleet that spread the same number of missiles over a half-dozen combatants. The more distributed fleet would also be more tolerant of losses. Currently, the USN has its power concentrated in high-end warships, be they carriers, large surface combatants, or nuclear submarines. However, this also makes the USN susceptible to major losses, especially if defenses don’t work as well as expected.

The U.S. has a significant lead in BFMs, but also has global commitments which may drastically reduce how many BFMs can be committed to a particular theater. In the western Pacific, the PLAN is rapidly narrowing this lead. As the United States builds towards a 355-ship Navy, it will need to carefully consider the missions required and, in wartime, the firepower required, to accomplish them.

A Bomber for the Navy

This article originally featured on Over The Horizon and is republished with permission. Read it in its original form here.

By Will Spears and Ross Hobbs

Abstract: Rather than sending the B-1 Lancer into early retirement, the Department of Defense could transfer it to the Navy for duty as a land-based ship-killer. Considering its speed, range, payload, and flexibility to employ the new Long-Range Anti-Ship Missile (LRASM), the B-1 is an ideal candidate for rebirth as a Sea Control Bomber.  

For better than a decade, the United States’ defense establishment has agonized over China’s aggressive military modernization. A growing arsenal of land-based anti-ship missiles abets an increasingly capable and assertive Chinese navy, threatening to quietly transform the East and South China Seas into de-facto Chinese territory if not forcefully challenged. The military aspects of this competition demand an ability to fight in the contested environment, prompting the development of concepts like the former Air-Sea Battle and its successor, JAM-GC, as well as a steady drumbeat of calls from senior leaders for disruptive thinking and creative solutions.

It was in this spirit of disruptive thinking that, at a CNAS-hosted panel discussion titled “A New American Way of War,” former Deputy Secretary of Defense Robert Work casually offered up a fascinating bit of heresy:

“If the Air Force is getting rid of the B-1 bomber, I’d say ‘You are out of maritime strike.’ We’re going to give the B-1 to the Navy, we’re going to load up with 3,000 LRASMs, and we’re going to base them in Guam and all over the place, and in the first 72 hours [of a conflict] they are going to go out and hunt down and kill every ship in sight.”

Amateurs gush disruptive ideas all the time, but when an industry heavyweight like Robert Work speaks out, it’s prudent to explore his opinions. Work’s conjecture was nested in a broader discussion, beginning around the 53-minute mark, lamenting the self-imposed limitations of “jointness” in driving procurement decisions. Rather than treating land-based strike as a proprietary mission of the Air Force, Work suggests that the Navy revive its concept of the Patrol Bombing (VPB) Squadron, which employed land-based aircraft to sink enemy ships in WWII. A force of LRASM-equipped naval patrol bombers, Work contends, could destroy an adversary’s fleet from the air without tangling with its anti-ship missile systems.

“In other words,” Work continued, “give the whole Chinese anti-access / area denial network no targets to shoot at.”

Secretary Work is not the only defense expert to propose that the Navy get into the bomber business. Analyst Robert Haddick devoted several pages of his influential book Fire on the Water to the idea. Unlike Work, Haddick proposed that the Navy acquire its own fleet of the next-generation Long Range Strike Bomber (or what has become the B-21), in a joint arrangement with the Air Force. To pay for it, Haddick suggested that the Navy scale back on purchases of the Gerald R. Ford-class aircraft carriers, F-35C Joint Strike Fighters, and DDG-51 Arleigh Burke-class destroyers, which he argued would be of limited usefulness in a missile-contested environment. Haddick wrote:

“With these stealthy bombers instead, the Navy would have maritime airpower that would actually be useful against China’s navy under way in the heavily defended Near Seas and against the PLA’s naval bases and ‘anti-navy’ forces—missions too dangerous for the Navy’s aircraft carriers and destroyers.”

Work and Haddick both recognized that a Navy-operated bomber runs against contemporary notions of “jointness,” notions which Work characterized as a “monolithic cudgel.” They both emphasized the importance of mission effectiveness, or “what can get the job done,” over parochial service interests or respect for swim lanes. For Haddick, specifically, it’s all about who is responsible to achieve control of a contested sea—a perennial Navy mission. If the Navy will be held accountable to control the sea, Haddick argued, then it should have the tools necessary to do it. That, to Haddick, means bombers. He continued:

“Under the theories of Air-Sea Battle and joint operational access, it shouldn’t matter which service, or combination of services, actually does the work. But in practice, the Navy will have the most intense interest both in maritime challenges, such as land-based “anti-navy” forces, and in development of the capabilities and doctrine necessary to cope with such challenges. Top-level policymakers interested in making sure the “anti-navy” problem is fixed will have a strong reason to assign the problem—and the resources—to the Navy.”

Fire on the Water was published in 2014, and while it has become required reading in war colleges for its depiction of China’s military expansion, Haddick’s call for a naval variant of the Long-Range Strike Bomber never garnered much attention. Concern over the high-end fight has only grown, though, and Work’s recent conjecture is a case in point which reframes Haddick’s argument. A rigorous testing program has determined the B-1 could fly through 2040 without a major life extension, but the Air Force has decided to retire it early to make room for the B-21 Raider. What if, instead of going to the boneyard, the B-1 were reassigned to the Navy?

The B-1 as a Sea Control Bomber

The Rockwell B-1 has had an interesting ride as a program of record. Designed to replace the 1960s-era B-52 as the Air Force’s primary nuclear bomber, the first B-1A flew in 1974. It was canceled by the Carter administration before entering production but then revived as the B-1B Lancer under Reagan. The B-1B featured improved avionics and greater payload than its predecessor, as well as an 85 percent reduction in radar cross-section at a slight penalty to speed. 100 were built; 63 remain in service today. It was divested of the nuclear mission in 1994, its enormous bomb bays repurposed to a variety of conventional attack munitions.

A classic example of Cold War-era design for lethality, the B-1 offers a combination of speed, flexibility, payload, and range that remains unmatched in its class. Capable of traveling for hours at near supersonic speeds, it can surge across vast oceans faster and with less refueling support than any current US or allied nation aircraft. It is also more maneuverable than other bombers and far more flexible. B-1 crews train at both high and low altitudes to perform a variety of mission sets, including large-scale standoff weapon attacks, large-scale Joint Direct Attack Munition (JDAM) attacks, Close Air Support (CAS), Strike Coordination and Reconnaissance (SCAR), Non-traditional Intelligence, Surveillance, and Reconnaissance (NTISR), and Air Operations in Maritime Surface Warfare (AOMSW) which includes Counter Fast Attack Craft (FAC)/Fast Inshore Attack Craft (FIAC), Aerial Mine Laying, and War at Sea against surface vessels.

The Navy’s primary use for the B-1 would be for the delivery of standoff weapons like LRASM or the Joint Air-to-Surface Standoff Missile (JASSM) against peer adversaries. These could destroy high-end warships and coastal cruise missile systems on short notice and from a comfortable distance, creating multiple avenues of approach for distributed naval forces. In scenarios short of war, they provide a powerful deterrent to maritime aggression, demonstrating both the capability and the resolve to project power into a contested environment. In asymmetric or low-intensity conflicts the B-1 would continue to deliver the same versatile combat power that it has for decades, only it would be administered by the Navy instead of the Air Force.

This versatility is probably the B-1’s most compelling feature. Of all bombers in service, the B-1 doesn’t just carry the largest payload (75,000 pounds; the B-52 and B-2 carry 70,000 and 40,000 pounds respectively), but its repertoire of supported weapons and combat systems is among the most elaborate fielded by any aircraft today. Included are the aforementioned long-range standoff weapons (LRASM and JASSM), as well as GPS- and laser-guided JDAMs (GBU-31, 38, 54), unguided bombs and sea mines (Mk-82, 84, 62, 65), and a multitude of sensors including the Sniper targeting pod and a Synthetic Aperture Radar. It also features a powerful defensive avionics suite, capable of providing electronic countermeasures against advanced threat systems.

Some examples of potential Navy combat loadouts and mission sets are below. B-1 squadrons normally train to a minimum of two aircraft for a given mission, so the ordnance brought to bear would probably reflect some multiple of the following:

  • Sea Denial: 24 LRASM
  • A2/AD Rollback: 8 LRASM & 16 JASSM
  • Strategic Attack: 24 JASSM
  • Aerial Mine Laying: 84 Mk-62 or 12 Mk-65
  • Counter FAC/FIAC: 10 CBU-105D/B and 6 GBU-54
  • CAS for SOF/USMC: 8x GBU-31, 6x GBU-38, 6x GBU-54

In addition to firepower, versatility is also a function of range. Without aerial refueling, the B-1 can fly for over 8 hours, or approximately 3,500 nautical miles. To put this in perspective, it can fly from Hawaii to Guam without refueling, or perhaps more pertinently, from Guam to the Taiwan Strait and back. With refueling, B-1 missions have exceeded 24 hours. A notional Concept of Operations could distribute the B-1 fleet between CONUS naval air stations and established overseas airbases like Andersen (Guam), Hickam (Hawaii) and Al Udeid (Qatar). Like they are today, these would remain on-call 24/7 for immediate response to emergent tasking with or without aerial refueling. Deployed in concert with missile-bearing attack submarines, and empowered by flexible refueling options like carrier-based unmanned tankers, a distributed force of Sea Control Bombers would present a complex and risk-prohibitive planning dilemma to any would-be maritime aggressor.

Many critics would argue that any new aircraft acquisitions should be unmanned. That may be true, provided that we ignore the unresolved issues with autonomous targeting in a communications-denied environment. At any rate, the B-1 is not a new acquisition; it is a thoroughly established system. In this sense it can serve as a proof-of-concept, buying time for an autonomous replacement to achieve Initial Operational Capability (IOC).

Costs

For navalists intrigued by the B-1’s superlative capabilities, excitement should be tempered with respect for its costs. Unsurprisingly, the B-1 is a labor-intensive beast, demanding 74 maintenance man-hours per flying hour (MMH/FH) with an estimated cost per flying hour of $70K (to be fair, the B-52 also costs about $70K per flying hour, while the B-2 costs between $110K and $150K). These are Air Force estimates and may not be perfectly fungible with the Navy’s models for aircraft ownership costs, but their implications are clear. Even if the B-1 fleet were reassigned to the Navy “free of charge,” there is little doubt that manning and maintaining it would be expensive.

Then there’s the matter of age. Due to factors like fatigue and diminishing manufacturing sources, aircraft tend to become more expensive to keep airworthy as they get older. While various modernization efforts have prevented the B-1 from falling into obsolescence, the airframe is clearly in the “aging” phase of its life cycle, as Congressional Budget Office analysts found that the B-1’s cost per flying hour grew by a real rate (i.e., independent of inflation) of 2.9% between 1999 and 2016.

Some of the B-1’s ownership costs will be reduced through modernizations as moving parts are eliminated and high-failure electronics are replaced with solid-state circuitry. Some of these modernization efforts are in progress today; others were shelved with the decision to retire the B-1 but could be revived. Additional savings could be gleaned by accepting sacrifices in performance, as might be prudent upon reassignment of the B-1 to a different mission. For instance, if the Sea Control mission set does not require supersonic speeds, the B-1 could be outfitted with engines that are less powerful but more reliable and fuel-efficient. Any such modifications would demand an initial injection of funding, though, as would the necessary modernizations to keep the airframe flying through 2040 or beyond.

Heresy

When viewing B-1’s costs against the anticipated price of the B-21 Raider program, it’s little surprise that the Air Force is ready to retire it. It is hardly efficient to support four different classes of bomber simultaneously. Their decision raises the question, though: If the B-1 is too expensive for the Air Force, whose primary mission is long-range strike, then how could it be affordable to the Navy, whose primary mission is not long-range strike? If the B-1 were reassigned to the Navy without additional funding to man and maintain it, then it could easily turn into a financial albatross, diverting resources from core Navy priorities (e.g., warships) to essentially duplicate the capabilities of a sister service.

The heresy of a Navy-operated, land-based long-range bomber crosses service lines. For the Air Force, it would represent an intrusion upon what has long been its operational territory as well as the original rationale for its existence as an independent armed service. From a more practical standpoint, rather than turn over a fully furnished weapons system to another service, Air Force leadership would almost certainly prefer to gut the B-1 and its associated logistics tail, keeping the useful parts inside the Air Force.

For the Navy, practical concerns could be difficult to distinguish from emotional resistance, because taking on the B-1 would probably demand sacrifices in some programs more traditionally recognizable as “Navy.” In theory, being land-based should have no bearing on the B-1’s legitimacy as a naval instrument, because the Navy has long relied upon land-based aircraft. Platforms like the P-8 Poseidon and the MQ-4C Triton are critical elements of today’s balanced fleet. In reality, though, a heavy bomber like the B-1 would upset the balance, instantly becoming one of the Navy’s most exquisite and potent offensive weapons. It would give credence to the charge, which the Navy denies carefully, that major surface combatants and aircraft carriers are too vulnerable to fight under threat of weapons like the DF-21D.

At issue is the Navy’s sense of identity, and whether it is derived from what a navy is (ships and aircraft… but principally ships) or what a navy does (control the maritime domain). Indeed, many of the Navy’s traditional missions would receive no value from the B-1. It cannot pull into a new ally’s port for a courtesy visit, nor can it board and search a vessel suspected of trafficking weapons. It cannot destroy a midcourse ballistic missile, nor can it hunt and kill enemy submarines. What the B-1 can do is sink ships, a lot of them, and quickly. It can do this on short notice across vast distances, and it can do it without engaging “A2/AD” missile systems. That the Navy could use a weapon like that is beyond dispute; whether it should, depends on what the Navy would give up and the relative importance of the Sea Control mission. It is worthy of analysis.

Ultimately, it may not be about what either service wants, but what Congress wants. The B-1 fleet is a major investment of national treasure, and Congress could decide that it should be kept airworthy through the entirety of its service life as a matter of good stewardship. Some representatives, ostensibly concerned about peer adversaries and a relative decline in US military power, may prefer to keep the B-1 flying in whatever capacity could be justified. Under this scenario, it would certainly be simpler and cheaper to keep it under the Air Force, unless Congress was persuaded that the Navy would make better use of it.

Closing Thoughts

The B-21 is expected to reach IOC in the mid- to late- 2020s, with the phase-out of B-1 beginning in 2030. Air Force Global Strike Command has already begun to shift focus away from the B-1, having announced intentions to extend the B-52 through 2050. Once the B-21 starts flying, support for B-1 will almost certainly stop. Considering these timelines, if B-1 were to be reassigned to the Navy, the ideal time for transition would be sometime between 2028 and 2030.

The B-21, similar to the B-2 in its design concept and stealth features, is not capable of replacing the B-1’s speed, flexibility, or payload. The early retirement of the B-1 will represent a decline in flexible US striking power across all Unified Combatant Commands at a time when it is needed most. Ideas for keeping that power at the ready, however unorthodox, should be explored thoroughly. This article’s purpose has not been to advocate for the B-1’s reassignment to the Navy, but to advocate for its consideration by a third party independent of service biases. Without thorough and professional analysis, there are too many variables at play to comment on whether this idea would be good or bad for the Navy, the Air Force, or the nation. This much is certain though: The B-1’s continued service would be bad for the PLA Navy.
