UGM-133 Trident II D-5 is an American three-stage SLBM solid-fuel ballistic missile with an operating range of 2500 to 11,000 km. This missile is currently the only SLBM type to be equipped with U-boats. Passed by Ohio and British Vanguard D-5 missiles, the in-flight Astronauts are guided by in-flight tracking systems that provide them with a CEP error margin of 90-120 meters. Although Trident II can carry up to fourteen heads, they currently only carry up to eight MIRVs with 100 or 475-tonne thermonuclear loads.

Genesis Strat-X The origins of the Trident rocket system date back to the early 1960s, when, according to US assessments, the development of Soviet offensive and defensive capabilities stymied US chances of surviving the first nuclear strike and the ability to make an effective response. These assessments were influenced both by the development of Soviet anti-ballistic missile defense (ABM) and by the forces of submarine warfare (ZOP), as well as the Soviet technological advances in ballistic missile guidance systems and multi-head technology. Secretary of Defense Robert McNamara

At the same time, the US Navy developed the SLBM Poseidon C-3 missile system's scientific research program, and the US Air Force promoted the ICBM program of the WS-120A. However, there was a lack of coordination between the various armed forces in the development of strategic weapons. In order to deal with all these issues, Secretary of Defense Robert McNamara ordered Strat-X studies in 1966 to identify possible alternatives to counteract the Soviet ABM system and increase the viability of the Soviet first nuclear strike by the United States. Strat-X participated in United States Navy and United States Air Force officers and civilian scientists and engineers. Strat-X focused on considering about 125 alternative rocket designs, with only two being based on marine systems. In this latter area, both the transfer of ballistic missiles by surface ships and the new type of submarine - described as suboption - were considered. The alternative was based on the new Poseidon missiles, carried by 31 existing Polaris ships and 20 to 25 new types. In the final conclusions of Strat-X, four new missile systems were proposed:

In response to a request from the Secretary of Defense, Strat-X proposed instead of the best strategic system a set of land and sea options. Ultimately, the only possible solution to this problem was ULMS. Within the Strat-X, a missile of 15.2 m in length and 2 m in diameter was considered - significantly larger than the current Poseidon missile. The concept of using such a large projectile led to the initial vision of the ULMS ship displacement at 8240 m and 135 m in length. Twenty-four projectiles were supposed to be horizontal (rather than vertical) in protective capsules outside the rigid hull, which could be released from the ship at any time. its speed and depth of immersion. In order to avoid revelation of the position of the ship by the reconstructed trajectory of the projectile, the firing was delayed, which greatly increased the survival chances of the ship. The ULMS was supposed to have a nuclear propulsion system with a relatively low speed of 25 knots. Speed ​​limitation was due to the assumption that higher speed would increase
