Nimrod British Aerospace
Nimrod
Maritime Patrol/
Anti-Submarine Plane

DESCRIPTION:
The Nimrod is a highly capable maritime reconnaissance platform that served with distinction in the Falkland Islands War with Argentina. The airframe is based on that of the de Havilland Comet airliner but with new engines and an enlarged lower fuselage containing a weapons bay. The most recent model is the MRA.4 equipped with much more capable radar, faster computers, and other avionics.

Unfortunately, the program has been hampered by serious safety concerns due to the age of the basic airframe and a high profile crash during operations in Afghanistan.

KNOWN VARIANTS:
HS 801 Prototype built by Hawker Siddley before its acquisition by British Aerospace, modified from Comet 4C airframes with a shorter fuselage, enlarged underfuselage, stronger landing gear, and other structural improvements; 2 built
MR.1 First production model built for electronic intelligence only; 46 built
R.1 Similar to the Nimrod MR.1 but with different underwing pods for special electronic reconnaissance missions; 3 built
MR.2 Maritime patrol plane with a new search radar, inertial navigation system, upgraded data processors, new navigation and acoustics analysis computers, and new comunications equipment; 35 MR.1 models upgraded to the MR.2 standard
