No, the Trident II is a missile carried by Ohio class subs.

Guidance: Inertial. Range: (Trident C4) 4,400 miles (7,100km), (D5) 6,800 miles (11,000km). Flight speed: Similar to Minuteman (Which is over 15,000mph (24,000km/h) at burnout, as given in the Minuteman entry) Warhead: Eight MK 4 (100kT each) MIRVs, with possibility of using Mk 500 Evader MARV (manoeuvring RV) later; (D5) not known And from Modern Submarine Warfare by David Miller and John Jordan; Military Press 1987. The Ohio class entry on page 138, under Armament: Armament: The Trident I C-4 missile has a length of 34ft (10.4m) and a diameter of 6ft 2in (1.9m). It comprises a three-stage solid-fuel rocket carrying eight 100kT MIRVed nuclear warheads. Since 1980 some missiles have had an alternative payload comprising eight Mk 500 Evader MaRvs (Manoeuvrable Reentry Vehicles) developed by Lockheed. Towards the end of the decade the Trident I C-4 will be superseded by the Trident II D-5 missile currently under development. The D-5 is a much larger missile than the C-4, with a length of 45ft 6in (13.9m) and a diameter of 6ft 11in (2.1m). Range will be a massive 6,000nm (11,100km) and a CEP of only 400ft (120m) is projected. The D-5 will carry up to 14 MIRVs of 150kT each, with an alternative payload of seven 300kT MaRVs. The four Mk 68 21in (533mm) torpedo tubes, which are located directly beneath ehe diminutive fin, fire the Mk 48 high-performance torpedo. As with the Los Angeles class, the torpedo transfer system is fully automated. Just thought I would include the whole entry. Modern Submarine Combat is part of a series with Naval, Land, Air books. And Modern Fighting Helicopters.
