Invincible-class Aircraft Carrier

The Invincible-class aircraft carriers are a class of four light carriers in the Royal Navy from 1980 through 2018. The vessels were built as aviation-capable anti-submarine warfare (ASW) platforms to counter the Cold War North Atlantic Soviet submarine threat, and initially embarked Sea Harrier aircraft and Sea King HAS.1 anti-submarine helicopters. Originally, the Invincible-class was intended to have a length of 686 feet (209.09 meters) however changes in the design included a 14 feet hull stretch. All four Invincible-class carriers are expected to be decommissioned between 2016 and 2018.
