NIMROD MR2/R1 (No Longer in service)


Nimrod M2 in flight

Nimrod was a development of the basic Comet No 4C airframe that dates from the late 1940s.

The Nimrod MR2 and MR4 were scrapped in March 2011.

The MR Mark 2P, which was developed for long-range maritime patrol. The Nimrod MR2 carried out three main roles; Anti-Submarine Warfare (ASW), Anti-Surface Unit Warfare (ASUW) and Search and Rescue (SAR).


Its long ferry range enabled the crew to monitor maritime areas far to the north of Iceland and up to 4,000 km out into the Western Atlantic. With AAR (Air-to-Air Refuelling), its range and endurance was greatly extended.

The MR2 was a very lethal submarine killer carrying the most up to date sensors and data processing equipment linked to the weapon systems. In addition to weapons and sonar-buoys, a searchlight mounted in the starboard wing pod could be used for search and rescue (SAR) operations. Crew members comprised 2 x Pilots and a flight engineer operate the flight deck, 2 x Navigators, an Air Electronics Officer (AEO), the sonobuoy sensor team of 3 x Air Electronic Operators and 4 x Air Electronic Operators to manage a wide range of avionics and weapon systems .

The second version was the R Mark 1, an aircraft specially fitted out for the gathering of electronic intelligence and only three were known to be in service. This was a highly secret aircraft that had been in RAF service since 1971 and about which little was known except that had been spotted on patrol over the Baltic Sea. The Nimrod R1s were externally distinguishable from the maritime reconnaissance version by the absence of the magnetic anomaly detection tail booms and a distinctive pod on the leading edge of the port wing. In-flight refuelling probes were added in 1982.

Nimrod MR4A

Under a 2.2 billion contract in July 1996, the Nimrod upgrade programme involved 21 Nimrod MR2 aircraft to Maritime Reconnaissance Attack 4 (MRA4) standard, together with training and integrated logistics support packages.

Nimrod MR4A was to have a reach extending to some 6,000 miles, compared to the previous MR2 capability of some 3,800 miles. Rolls BR710 engines replaced RR Spey engines. Other capability improvements over MR2 included increased time on station, a major improvement in overall sensor performance and weapon carrying capability. The new digital, integrated mission system features the Searchwater 2000 radar, UYS503/AQS970 sonar, DASS 2000 ECM, and EL/L8300UK ESM. The crew complement was reduced by 25%.

Weapons included torpedoes (Tigerfish), AGM-84 Harpoon anti-ship missiles (range 50 nautical miles) or AIM-9 Sidewinder air-to-air missiles for defence against hostile aircraft.

All the Nimrods were scrapped in March 2011.
