Nimrod (The Mighty Hunter)

The Roy Chadwick Lecture

The use of non-rigid airships (blimps) to search for the presence of submarines in off-shore waters gave birth to the concept of maritime air patrol during the First World War. These missions were then complemented by single-engine biplanes which were used along coast lines at the end of the war. Floatplanes and flying boats entered the scene in the 1920s and World war II saw the introduction of long-range aircraft in the form of H6K/H8K, Fw 200, BV 138, B-24, Catalina, ... etc.

It was the Battle of the Atlantic that gave the impetus to focus on the design of aircraft dedicated for these types of mission and the first purpose-built machine to fly on 17 May 1945 was the Lockheed P-2 Neptune. Others followed in the form of the Grumman S-2 Tracker (04 Dec 1952) for ship-borne operations and the Breguet Br.1150 Atlantic (21 Oct 1961). This talk will concentrate on the development of land-based maritime patrol aircraft.

The Avro Shackleton which was a descendant of the Lincoln and the Tudor, made its maiden flight on 09 March 1949. It took over the duties for the British from the Neptune as the Cold War began but turbojets were attached to both types to boost the take-off and the dash performance capabilities. Whilst the Americans and the Russians replaced their assets with turboprop powered Lockheed P-3 Orion and the Ilyushin Il-38 Dolphin respectively, the re-thinking in the UK led to the first all-jet maritime patrol aircraft based on the De Havilland Comet.

Thus was born the Nimrod which proved to be very competitive and was to see service with the RAF over 42 years. No other military mission involves the fusing together of data flowing in from a bewildering variety of sensor packages required to conduct anti-submarine warfare. The Nimrod also proved to be very effective in performing search & rescue missions. This talk will explain the reasons behind the switch to fanjets, illustrated with simple performance curves and will briefly examine the electronic intelligent gathering and the airborne early warning variants. It will be concluded with a look at the Nimrod replacement, the Boeing P-8 Poseidon and compare it with the Kawasaki P-1 which replaced the ShinMaywa US-2
