American naval ballistic systems

The development of submarine-launched ballistic missile (SLBM) systems was a critical aspect of the Cold War arms race between the United States and the Soviet Union. These systems, deployed on nuclear-powered submarines (SSBNs), were at the forefront of technological competition between the two superpowers, driving advancements in both military and civilian technologies, including space exploration. The rivalry shaped the design, automation, and operational tactics of these systems, reflecting the distinct economic, scientific, political, ideological, and cultural characteristics of each nation. While both countries pursued similar strategic goals, their approaches to SLBM development diverged significantly, with each responding to the other's technological advancements.

Technologically, the United States favored solid-fuel rocket engines for their SLBMs. The United States Navy emphasized human control, particularly over nuclear reactors, prioritizing stealth through noise reduction. The nation achieved significant innovations, occasionally gaining advantages in specific technical areas. SLBM systems were the most effective means of strategic nuclear deterrence, forming a cornerstone of their respective nuclear triads, alongside land-based missiles and strategic bombers, except during the early Cold War period.

The concept of submarine-launched ballistic missiles is related to the German V-2 rocket program during World War II. In 1944, Klaus Riedel, a member of the Peenemünde research team, proposed launching V-2 rockets from the North Sea against Great Britain, using submarines to tow launch containers. These containers, approximately 32 meters long, 5.7 meters in diameter, and with a displacement of 500 tons, housed a single V-2 missile, crew quarters, a control center, and fuel and ballast tanks. A single submarine could tow up to three containers. Plans also included towing containers across the Atlantic to target New York City. The crew would travel aboard the submarine, transfer to the container for fueling, and launch the missile. The project, developed at the AG Vulcan Stettin shipyard in Szczecin, reached 65–70% completion for three containers by the war's end, with a prototype tested near Peenemünde.

After the war, many German V-2 scientists, including Wernher von Braun, were recruited by the United States to bolster its ballistic missile program under the United States Army. In October 1946, the NKVD arrested approximately 5,000 German specialists, relocating them to the Soviet Union to advance Soviet ballistic missile development. As a result, the German V-2 designers made a significant contribution to both the American and Soviet ballistic missile programs.

Starting in October 1945, the United Kingdom, the United States, and the Soviet Union began a series of tests on captured or assembled V-2 missiles. On 6 September 1947, an "American" V-2 was launched from the deck of the aircraft carrier USS Midway (CV-41), marking the first-ever launch of a ballistic missile from a mobile platform. From that point on, guided missile ships – vessels capable of carrying and launching rockets – became a priority for the United States Navy. The first such vessels were to be multi-role aircraft carriers, capable of both carrying ballistic weapons and fulfilling the usual functions of this class, as well as the unfinished battleship USS Kentucky (BB-66) and the large cruiser USS Hawaii (CB-3). The United States was aware of the German concept of underwater missile launchers, but showed little interest in this idea at the time, placing greater hopes in sea-launched cruise missiles for long-range strikes. The newly formed Air Force (United States Air Force) conducted research in ballistic technology, competing with the United States Army's program led by von Braun.

After launching a V-2 rocket from the aircraft carrier Midway in 1947, the United States Navy paid little attention to ballistic missiles, focusing instead on other types of new weaponry – particularly those related to aircraft carriers. One of the few instances of interest from the United States Navy in ballistic missile weaponry during this period came in 1950, when Commander Francis D. Boyle – a World War II submarine commander – proposed adapting existing submarines into guided missile submarines. This innovative idea included, among other things, vertical launch tubes and replacing traditional propeller-based propulsion with pump-jets. However, no ballistic missile program was undertaken by the United States Navy at that time.

The idea gained momentum only after the Soviet Union conducted a hydrogen bomb test on 12 August 1953. Fear of Soviet advancements in strategic missile technology pushed the United States Department of Defense to order the Navy to join the United States Army's IRBM (Intermediate-Range Ballistic Missile) program. In the Navy's case, the missile would be launched from surface ships. Naval leadership, however, was highly skeptical of joining the Army's program, which involved the liquid-fueled Jupiter missile. This fuel was considered too hazardous for handling at sea. The missile itself, measuring 18.3 metres, was also thought to be too unwieldy even aboard a surface vessel.

At the time, the Navy had two additional unofficial reasons for its reluctance to pursue a ballistic missile program. First, since the late 1940s, the Bureau of Aeronautics and the Bureau of Ordnance had each been independently developing cruise missile programs (for submarines) intended for land-attack missions. Neither bureau was willing to divert its scientific and engineering resources to a ballistic missile initiative. The second unofficial reason stemmed from the Navy's bitter loss in a high-profile inter-service rivalry with the Air Force over the B-36 bomber versus the United States-class aircraft carriers. This defeat cost the Navy significant prestige and led to the cancellation of the United States carrier program, an episode known as the "Revolt of the Admirals". As a result, Navy leadership wanted to avoid another inter-branch conflict – this time over ballistic missiles. A further and more tangible reason for resistance was concern over the financial burden of developing a new class of weapons outside the Navy's regular budget. Tensions reached a point where Admiral Robert Carney, Chief of Naval Operations from 1953 to 1955, imposed restrictions on naval officers who supported the ballistic missile program.
