Chief of Naval Operations Admiral Arleigh Burke appointed Rear Admiral W. F. "Red" Raborn as head of a Special Project Office to develop Jupiter for the Navy in late 1955 ...
The short range of the early SLBMs dictated basing and deployment locations. By the late 1960s the Polaris A-3 was deployed on all US SSBNs with a range of 4,600 kilometres (2,500 nmi), a great improvement on the 1,900 kilometres (1,000 nmi) range of Polaris A-1. The A-3 also had three warheads that landed in a pattern around a single target.
The short range of the early SLBMs dictated basing and deployment locations. By the late 1960s the UGM-27 Polaris A-3 missile was deployed on all US and UK ballistic missile submarines. Its range of 4,600 kilometres (2,500 nmi) was a great improvement on the 1,900-kilometre (1,000 nmi) range of Polaris A-1.
The missile only flew 30 km (19 mi) and fell short of the expected minimum range of 300 km (190 mi). [ 28 ] [ 29 ] [ 30 ] However, North Korean state media claimed success. According to North Korea, the missile was launched from its maximum underwater depth, and the " cold launch " ejection mechanism, solid-fueled rocket engine, the flight ...
The C3 was the only version of the missile produced, and it was also given the designation UGM-73A. [3] Slightly longer and considerably wider and heavier than Polaris A3, Poseidon had the same 4,600 kilometres (2,500 nmi) range, greater payload capacity, improved accuracy, and multiple independently targetable reentry vehicle (MIRV
Its principal finding was that the Americans had developed a new version of the Polaris missile, the A-3. With a range of 2,500 nautical miles (4,600 km), it had a new weapons bay housing three re-entry vehicles (REBs or Re-Entry Bodies in US Navy parlance) and a new 200-kilotonne-of-TNT (840 TJ) W58 warhead expected to become available around ...

The ship was assigned to the 10th Submarine Squadron (United Kingdom) where it operated as the first of the UKs new Polaris based nuclear deterrent. [2]Her Polaris system was updated in 1984 with the Chevaline IFE (Improved Front End) that included two new warheads and re-entry bodies and penaids, super-hardened to resist ABM attack, replacing the original three ET.317 warheads.
