American submarine-launched ballistic missile. SLBM, 2 stages, inertial guided, nuclear MIRV warhead, range that of twice Polaris A-3.

AKA: Mk.300;Poseidon;Poseidon C-3;UGM-73;UGM-73A;W68. Status: Retired 1990. First Launch: 1968-08-16. Last Launch: 1990-04-30. Number: 268 . Payload: 1,630 kg (3,590 lb). Gross mass: 29,475 kg (64,981 lb). Height: 10.36 m (33.98 ft). Diameter: 1.88 m (6.16 ft). Span: 1.88 m (6.16 ft). Apogee: 500 km (310 mi).

In November 1963 the US Navy began studying a missile that would have the maximum possible capability within the confines of the existing Polaris submarine launch tubes. Diameter would be increased by deleting the spacers between the tube walls and the missile. Motor lengths would be shortened by use of nozzles submerged in the propellant load. Near-intercontinental range was expected, allowing the missiles to be fired from anywhere in the world's oceans rather than identifiable zones closer to Soviet coasts. After Air Force objections range was traded off for carriage of more payload – up to 14 Multiple Independent Reentry Vehicle warheads. The missile's name was changed from Polaris B3 to Poseidon C3 in 1965 – a move the Department of Defense bitterly regretted, since it targeted the missile with Congress as a ‘new' missile subject to intense scrutiny, rather than a ‘modification' of an existing design. First test launch was in August 1968, first submerged launch in August 1970, and the missile went on its first operational cruise in March 1971. Reliability problems with early production missiles and dud warhead issues were solved by 1974. During submarine overhauls, Polaris missiles would be replaced by Poseidon, and by 1981 Poseidon had replaced Polaris in the fleet. Poseidon in turn was replaced by the Trident C4 in 1979-1992.

Poseidon's accuracy was only 10% better than Polaris, the result of an intentional decision by the Department of Defense not to develop precision stellar-inertial guidance for the missile. The official position was that the Navy's SLBM's were to be a retaliation weapon against Soviet cities, without the capability of making a first strike against military targets.

Development Cost $: 1,092.600 million. Recurring Price $: 3.957 million in 1973 dollars. Flyaway Unit Cost 1985$: 2.483 million in 1973 dollars. Maximum range: 4,650 km (2,880 mi). Number Standard Warheads: 14. Standard RV: Mk.300. Standard warhead: W68. Warhead yield: 50 KT. CEP: 0.53 km (0.32 mi). Boost Propulsion: Solid rocket. Initial Operational Capability: 1971. Total Number Built: 640. Total Development Built: 21. Total Production Built: 619.
