The aircraft that mastered the art of the vertical strike

In short: The Harrier II redefined aerial warfare by mastering vertical and short takeoff capabilities. It allowed the Royal Air Force and Royal Navy to project power from aircraft carriers and austere land bases alike, becoming a cornerstone of British combat operations in Kosovo, Iraq, and Afghanistan for decades.

Developed as a successor to the first-generation Harrier, the Harrier II was a joint US-UK effort that began in 1973. While the British government initially had modest requirements, the project evolved into a sophisticated platform. By 1982, the UK committed US$280 million to ensure the aircraft met specific British needs, including a unique wing design with leading-edge root extensions. The aircraft eventually entered service in July 1987, featuring a composite fuselage for weight reduction and a one-piece wing that provided 14 per cent more area than its predecessors.

The Harrier II was distinguished by its specialized role in air interdiction and close air support. Unlike its American counterpart, the British version never carried a radar, a decision made by the Ministry of Defence who deemed the cost of transferring a radar from the Sea Harrier to be too high—estimated at over £600 million.

Instead, it relied on advanced avionics like the ZEUS Electronic Countermeasure system, which cost approximately $1.7 million per set, and a suite of day and night operability tools including a head-up display and multi-purpose color displays. Its operational legacy is defined by high-precision warfare. During the 1999 Kosovo campaign, the Harrier achieved a reported 80% direct hit rate over 870 sorties. In Iraq, it famously deployed the AGM-65 Maverick missile, launching 38 during the 2003 campaign to strike fuel depots and Scud launchers. Despite its retirement in 2010 due to budgetary pressures, the Harrier II served as a vital pilot scheme for the joint operations that eventually led to the F-35B Lightning II.
