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.
The UGM-73 Poseidon missile was the second US Navy nuclear-armed submarine-launched ballistic missile (SLBM) system, powered by a two-stage solid-fuel rocket.It succeeded the UGM-27 Polaris beginning in 1972, bringing major advances in warheads and accuracy.
Yasen-class submarines, also known as Project 885M, are nuclear-powered cruise missile submarines, built to replace Soviet-era nuclear attack submarines as part of a programme to modernise the ...
While stationed about 6,000 kilometres (3,700 mi) southwest of Los Angeles, the American submarine USS Ethan Allen fired a Polaris-A2 missile at an open ocean target point 920 kilometres (570 mi) short of the then British Kiritimati (Christmas Island), south of Hawaii. [5] The missile traveled a distance of 1,020 nmi (1,890 km; 1,170 mi).
