GPS has been used on some test flights but is assumed not to be available for a real mission. The fire control system was designed and continues to be maintained by General Dynamics Mission Systems. Once the star-sighting has been completed, the "bus" section of the missile maneuvers to achieve the various velocity vectors that will send the deployed multiple independent reentry vehicles to their individual targets. The downrange and crossrange dispersion of the targets remains classified.

When the third-stage motor fires, within two minutes of launch, the missile is traveling faster than 20,000 ft/s (6,000 m/s), or 13,600 mph (21,600 km/h) Mach 18.

In 2002, the United States Navy announced plans to extend the life of the submarines and the D5 missiles to the year 2040. This requires a D5 Life
Extension Program (D5LEP), which is currently underway. The main aim is to replace obsolete components at minimal cost by using commercial off the shelf

In 2009, the United States upgraded the warheads carried by
American D5 missiles with an arming, fuzing and firing (AF&F) system called the "super-fuze" that allows them to time their detonation to target silos and bunkers more accurately, greatly increasing their effectiveness against hardened

In 1971, the US Navy began studies of an advanced
Undersea Long-range Missile System (ULMS). A Decision Coordinating Paper (DCP) for the ULMS was approved on 14 September 1971. ULMS program outlined a long-term modernization plan, which proposed the development of a longer-range missile termed ULMS

The primary drawback of using conventionally armed ballistic missiles is that to missile warning systems, they are virtually indistinguishable from nuclear armed missiles. This leaves open the likelihood that other nuclear-armed countries might mistake it for a nuclear launch which could provoke a

Trident was built in two variants: the I (C4) UGM-96A and II (D5) UGM-133A; however, these two missiles have little in common. While the C4, formerly known as EXPO (Extended Range Poseidon), is just an improved version of the Poseidon C-3 missile, the Trident II D-5 has a completely new design

The launch from the submarine occurs below the sea surface. The missiles are ejected from their tubes by igniting an explosive charge in a separate container. The energy from the blast is directed to a water tank, where the water is flash-vaporized to steam. The subsequent pressure spike is strong

US Navy Vice
Admiral Johnny Wolfe, in charge of overall submarine weapons systems procurement, indicated in 2020 that he had initiated trade studies to apply lessons from the D5LE program to extend the Trident II's lifespan to 2084. Wolfe said he expected the first D5LE2 missiles to be deployed

In May 1972, the term ULMS II was replaced with
