An unknown number of the missiles are also planned for deployment for non-strategic roles with 10 kT warheads. Each submarine can carry 16 missiles and are equipped with UK warheads believed to be similar to the W76 100 kT US warheads. In 1994, the United Kingdom began equipping the Trident D5 aboard its four Vanguard-class missile submarines. The Navy plans to deploy 12 Columbia-class submarines, each carrying 16 Trident D5 missiles in four “quad packs.” 13 The Navy’s forthcoming Columbia-class submarine will equip the Trident D5 as it enters service in the early 2030s. A 2016 report notes that nine Ohio-class submarines are deployed in the Pacific and five in the Atlantic. Each of these SSBNs carries 20 Trident D5s for a total arsenal of 240 SLBMs.
The United States maintains 14 Ohio-class submarines, with two in repair at any time. The Navy deployed a number of W76-2s by February 2020. 10 Congress appropriated $65 million in FY2019 and $10 million in FY2020 to fund the new warhead, which was designated the W76-2. The 2018 Nuclear Posture Review highlighted the need for a new low-yield Trident missile to deter adversary use of similarly low-yield nuclear weapons. It is three-staged and uses solid-propellant. The missile measures 13.42 m in length, 2.11 m in diameter, and weighs 59,090 kg at launch. The system uses an inertial navigation system combined with a stellar reference system that provides an accuracy of 90 m CEP. submarine-based missile capable of destroying hardened targets. This firepower makes the Trident D5 the first U.S. These RVs can be either the Mk 4 with a W76 100 kT yield warhead or the Mk 5, which has a W88 475 kT yield warhead. Its payload carries a Post-Boost Vehicle (PBV) which can carry up to 12 Reentry Vehicles (RVs), though New START limits the number to eight. The Trident D5 has a range of 12,000 km and can carry a payload as large as 2,800 kg. Navy has successfully conducted over 160 missile test launches. Since the Trident’s design completion in 1989, the U.S. 6 The second life extension program seeks to increase the Trident D5’s lifespan for another 60 years to deploy through the 1980s.

In January 2021, VADM Johnny Wolfe announced the Navy would start the Trident D5 Extension Life II upgrade this year. In June 2002, the Navy initiated the D5 Life Extension to replace aging missile parts and extend missile life from 30 to 44 years. However, Congress rejected funding for this program.
In the mid-2000s, the Defense Department requested to deploy conventionally-armed Trident D5 missiles to satisfy requirements for its Conventional Prompt Global Strike capability. An extensive upgrade for 300 missiles is planned in 2020 in order to upgrade them to the Trident D-5A or D-5LE versions with improved capabilities and an extended service life to 2042. New third-stage propellant motors were developed and tested and will likely be included in future versions. Improved air-burst fuses were considered for the Mk 4 RV in 1998. More accurate GPS systems have been tested on Trident missiles since 1993 and an earth penetrator version was considered in 1994 to attack underground facilities. The Trident D5 has undergone extensive improvement programs. However, the Navy eventually shifted its emphasis from increasing range to improving accuracy as the Trident D5’s counterforce mission became a focal design point. The Trident D5 was originally intended to significantly increase range compared to the first-generation Trident I C4. The first test launch took place in January 1987 and the first sea trial, which was unsuccessful, occurred in March 1989. The Navy began developing the Trident D5 in March 1980. These programs, categorized as US Fleet Ballistic Missile technologies, began in the mid-1950s. It improved upon earlier SLBMs including the Polaris, Poseidon, and Trident I C4.
