The British Aerospace Sea Harrier was a VTOL fighter-bomber based on the successful Harrier GR.3. It entered service with the Royal Navy in April 1980 as the Sea Harrier FRS.1. This aircraft was equipped with a single Rolls-Royce Pegasus turbofan engine, as well as a Ferranti Blue Fox radar. The early service variant of the FRS.1 included a bubble canopy that would characterize later variants of the Sea Harrier, it also featured AIM-9L AAMs for self defence, later variants of the Sea Harrier introduced modifications to the pylons, to be able to carry more AIM-9L sidewinders, as well as Sea Eagle anti-ship missiles after the Falklands War.

It was introduced in Update "Sons of Attila". The Sea Harrier FRS.1 (e) is not very different from many other Harriers in-game in terms of gameplay. It has very good acceleration, meaning that it is one of the first to take off from the runway, while also having access to a decent radar and 2 x AIM-9L Sidewinders. Like all Harriers, it features VTOL. It lacks any sort of guided ordnance for ground battles, but its 5 x 1,000 lb bombs are enough to destroy a base in air battles, or a couple of ground targets if used properly, though for this task more specialized attackers like the Jaguar are more recommended.
