The Hawker Siddeley Harrier is the first generation - version and is also known as the AV - 8A Harrier; it was used by multiple air forces, including the Royal Air Force (RAF) and the United States Marine Corps (USMC). The Sea Harrier is a naval strike / air defence fighter derived from the Hawker Siddeley Harrier; it was operated by both the Royal Navy and the Indian Navy. During the 1980s, a second generation Harrier emerged; manufactured in the United States as the AV - 8B and in Britain as the British Aerospace Harrier II respectively. By the start of the 21st century, the majority of the first generation Harriers had been withdrawn, many operators having chosen to procure the second generation as a replacement. In the long term, several operators have announced their intention to supplement or replace their Harrier fleets with the STOVL variant of the F - 35 Lightning II, designated as the F - 35B.
