7, 8. FLEET Ballistic Missiles

Lockheed Missiles & Space Company (LMSC) began development of the first Navy Fleet Ballistic Missile (FBM) Polaris A1 in 1956 and has managed lie program through three succeeding models, the Polaris A2 and A3 and the Poseidon C3 (pictured). Polaris, a two-stage solid propellant missile with a nuclear warhead, was the first global peace keeper to go on station. Polaris A1 was 28.5 feet long, weighed 30,000 lbs., had 1200 nautical mile range. A2 was 30 inches longer, weighed more, but increased range to 1500 n.m. Polaris A3 is 1 ft. longer than A2, weighs 35,000 lbs., and has 2500 n.m. range. Poseidon, 34 ft. long and 6ft. in diameter compared to 4½ft., weighs more than twice as much as its A1 ancestor and has about the same range as the A3 - plus MIRV, multiple independently targeted reentry vehicles.

Each nuclear powered FBM submarine carries 16 missiles.

Trident I will have the same dimensions as Poseidon but will have greater range. This is important not only for the number of targets it will be able to reach, but also because it allows the submarine to stand off a greater distance from targets, reducing the probability it will be detected and attacked. Submarines carrying Trident I can be on station while cruising an ocean area several times greater than if they were carrying Polaris or Poseidon. Trident I is scheduled to be operational along with the new Trident submarine in late 1970s.
