Hawker Siddeley Nimrod AEW3&MR2

The Hawker Siddeley Nimrod was a maritime patrol aircraft developed and operated by the United Kingdom. It was an extensive modification of the de Havilland Comet. 

The Nimrod was the first jet-powered maritime patrol aircraft (MPA) to enter service, being powered by the Rolls-Royce Spey turbofan engine

Various new ECMs and electronic support systems were retrofitted onto the Nimrod fleet in response to new challenges and to increase the type's defensive capabilities,additional equipment also provided more effective means of identification and communication. 

A number of modifications were introduced during the 1991 Gulf War, a small number of MR2s were fitted with improved Link 11 datalinks, new defensive ECM equipment including the first operational use of a towed radar decoy, and a forward looking infrared turret under the starboard wing.

 Nimrod AEW3 project 
In the mid-1970s a modified Nimrod was proposed for the Airborne Early Warning (AEW) mission. Eleven existing Nimrod airframes were to be converted by British Aerospace . The Nimrod AEW3 project was plagued by cost over-runs and problems with the GEC 4080M computer used. Eventually, the MoD recognised that the cost of developing the radar system to achieve the required level of performance was prohibitive, and in December 1986 the project was cancelled. The RAF eventually received seven Boeing E-3 Sentry aircraft instead.
