BAE Systems’ modernized Nimrod MRA4 program received consideration from the USA as a replacement option for its P-3C Orions, but pressures for standardization with the global civil air fleet and a desire for a “made in America” solution pushed them to adopt the 737-based P-8A instead. A British program was begun in 1996 to rebuild their existing Nimrod Mk2 fleet to the MRA4 standard with new wings, engines, internal systems, and mission systems. Unfortunately, that program faced a series of budget cuts, stalls, and conditions before getting a go-ahead for 12 aircraft in July 2006.
At present, the first Nimrod MRA4 isn’t expected to enter service until around 2010. Given the cutbacks in the modernization program, however, some older Nimrod Mk2 and MR1 airframes might have become available for sale and refurbishment.
