The W58 was an American thermonuclear warhead used on the Polaris A-3 submarine-launched ballistic missile. Three W58 warheads were fitted as multiple warheads on each Polaris A-3 missile.[2]
The W58 was 15.6 inches (400 mm) in diameter and 40.3 inches (1,020 mm) long, and weighed 257 pounds (117 kg). The yield was 200 kilotonnes of TNT (840 TJ).[1] The warhead used the Kinglet primary, which it shared with the W55 and W47 warheads.[3]
The W58 design entered service in 1964 and the last models were retired in 1982 with the last Polaris missiles.[1]
