American missile. Two stage vehicle consisting of 1 x A3P + 1 x X-260

The Polaris A3 greatly improved performance over the earlier models through use of constant-diameter rocket motors that completely filled the launch tube. Performance was also increased through use of fiberglass casings and improved propellants in all stages, and a 60% lighter guidance section. The missile delivered three spaced but not independently-guided W-58 warheads of 200 kT each. This created greater destruction than a single higher-yield warhead with the same throw weight. CEP was improved to 600 m (2000 ft). First launch was in August 1962, and the missile was deployed in September 1964. New deployments and replacement of older missiles meant that by 1974 all Polaris missiles in the fleet were the A3 model. The A3 in turn was progressively replaced by the Poseidon, with the last A3 pulled from its launch tube in October 1981.

Lockheed UGM-27 Polaris A-3

The Polaris A-3 was a significantly enhanced missile with all the extensive changes, which weren't incorporated in the A-1-2 because of the very short development time frame. The A-3 saved weight by using fiberglass casings for both stages, and a 60% lighter guidance section. The second stage used a completely new motor by Hercules, with a high-energy propellant and a single nozzle with fluid-injection thrust-vectoring control. These features increased range to 4600 km (2500 nm). The A-3 also had a completely new warhead section with three reentry vehicles, each carrying a 200 kT W-58 warhead. The inertial navigation system was also gradually improved, leading to an accuracy of about 600 m (2000 ft) CEP. The first (partially successful) test of a Polaris A-3 occurred in August 1962, and testing continued through 1964. The A-3 became operational in September 1964 aboard USS Daniel Webster (SSBN-626).

In June 1963, all Polaris missiles were designated in the UGM-27 series as follows:

SLBM Designation New Designation
A-1 UGM-27A
A-2 UGM-27B
A-3 UGM-27C

The UGM-27C eventually replaced all earlier UGM-27A-B missiles, and by 1974, only the Polaris A-3 was still in service. By that time, however, some A-3s had already been replaced by the new UGM-73 Poseidon C-3 SLBM. The final Polaris A-3 was withdrawn from service in October 1981. Between 1959 and 1968, Lockheed had produced about 1150 Polaris missiles of all versions, the majority (640+) being UGM-27Cs.
