Polaris A2


American missile. In comparison to the A-1, the Polaris A-2 had a slightly longer first stage and a lighter second-stage motor casing. These features increased range to 2800 km (1500 nm), the performance originally envisioned by the Navy.

The Polaris A2 was a production-standard missile that achieved the range originally specified for the system through use of a longer first stage and a lighter fiberglass second-stage motor casing. Higher-reliability avionics were also fitted. First launch was November 1960, and deployment in June 1962.

Failures: 16. Success Rate: 92.20%. First Fail Date: 1961-02-06. Last Fail Date: 1968-01-15. Standard warhead: 500 kg (1,100 lb). Maximum range: 2,820 km (1,750 mi). Number Standard Warheads: 1. Standard RV: Mk. 20B. Standard warhead: W47. Warhead yield: 800 KT. CEP: 2.90 km (1.80 mi). Boost Propulsion: Solid rocket. Initial Operational Capability: 1962.

Lockheed UGM-27 Polaris A-2

Given the very short development time of Polaris (only four years from development contract to operational deployment), it is not surprising that the A-1 version had room for improvements. The Polaris A-2 had a slightly longer first stage, using the full length of the missile tubes, and a lighter second-stage motor casing made of fiberglass instead of steel. These features increased range to 2800 km (1500 nm), the performance originally envisioned by the Navy. The A-2 also had new electronics for higher reliability. The first A-2 was launched in November 1960, and deployment of this version began in June 1962.

The re-entry vehicle reached the target zone 1890 km away and detonated at 3,300 m. The resulting mushroom cloud was observed by the submarines Carbonero (SS-337) and Medregal (SS-480), both stationed within 25 km of the predicted impact point.
