It was designed as a Royal Air Force maritime patrol aircraft, the Nimrod MR1/MR2, its major role being anti-submarine warfare (ASW), although it also had secondary roles in maritime surveillance and anti-surface warfare. It served from the early 1970s until March 2010. The current Nimrod series was due to be replaced by the now cancelled Nimrod MRA4.
The Nimrod MRA4 was intended to replace the capability provided by the MR2. It was essentially a new aircraft, with current-generation Rolls-Royce BR710 turbofan engines, a new larger wing, and fully refurbished fuselage. However the project was subject to delays, cost over-runs, and contract re-negotiations. It was cancelled in 2010 as a result of the Strategic Defence and Security Review at which point it was £789 million over-budget and nine years late. The prototype aircraft, produced at a cost of over £1bn each, have been scrapped.
