The Westland Lysander was a British army co-operation and liaison aircraft produced by Westland Aircraft. It was used during the Second World War and was renowned for its ability to operate from small, unprepared airstrips. This exceptional short-field performance made possible clandestine missions behind enemy lines that placed or recovered agents, particularly in occupied France. Like other British army air co-operation aircraft, it was given the name of a military leader; in this case, the Spartan general Lysander.

[edit] Design and development

In 1934, the Air Ministry issued the Specification A.39/34 for an army co-operation aircraft to replace the Hawker Hector. Initially, Hawker Aircraft, Avro and Bristol were invited to submit designs, but after some debate within the Ministry, a submission from Westland was invited as well. The Westland design, internally designated P.8, was the work of Arthur Davenport under the direction of W.E.W. (Teddy) Petter. It was Petter's second aircraft design and he spent considerable time interviewing Royal Air Force pilots to find out what they wanted from such an aircraft. The result of Petter's enquiries suggested that field of view, low-speed handling characteristics and STOL performance were the most important requirements.

Davenport and Petter worked to design an aircraft around these features: the result was unconventional and looked, by its 15 June 1936 maiden flight, rather antiquated. The Lysander was powered by a Bristol Mercury air-cooled radial engine, high gull wings and a fixed taildragger landing gear faired inside large, streamlined spats. The spats had mountings for small, removable stub wings that could be used to carry light bombs or supply canisters. In appearance it was not dissimilar to the Polish LWS-3 Mewa.

Despite its appearance, the Lysander was aerodynamically advanced; it was equipped with automatic wing slats, slotted flaps and a variable incidence tailplane. These refinements gave the Lysander a stalling speed of only 65 mph (104 km/h, 56.5 knots)[1]. It also featured the largest Elektron alloy extrusion made at the time: a single piece inside the spats supporting the wheels. The Air Ministry requested two prototypes of the P.8 and the competing Bristol Type 148, quickly selecting the Westland aircraft for production, issuing a contract in September 1936.

The first Lysanders entered service in June 1938 equipping squadrons for army co-operation and were initially used for message-dropping and artillery spotting. When war broke out in Europe, the earlier Mk Is had been largely replaced by Mk.IIs, the older machines heading for the Middle East. Some of these aircraft, now designated type L.1, operated with the Chindits of the British Indian Army in the Burma Campaign of World War II. [2] Four regular squadrons equipped with Lysanders accompanied the British Expeditionary Force to France. These were put into action as spotters and light bombers. In spite of occasional victories against German aircraft, they made very easy targets for the Luftwaffe unless escorted by Hurricanes. Almost half the Lysanders operating in and over France were lost and, with the fall of France, the type was quickly withdrawn from its army co-operation role. Back in England some went to work operating air-sea rescue for RAF pilots in the English Channel. Fourteen squadrons and flights were formed for this work during 1940-41, dropping dinghies to downed pilots.

[edit] Special duties

In August 1941, a new squadron, No. 138 (Special Duties), was formed to undertake missions for the Special Operations Executive to maintain contact with the French Resistance. Among its aircraft were Lysander Mk.IIIs, which would fly over and land in occupied France. While general supply drops could be left to the rest of No. 138's aircraft, the Lysander could insert and remove agents from the continent or retrieve allied aircrew who had been shot down over occupied territory and had escaped capture. For this role, the Mk IIIs were fitted with a fixed entry / exit ladder over the port side to hasten access to the rear cockpit and a large drop tank under the belly. The Lysander proved to be a success in this role and continued to undertake such duties until the liberation of France in 1944.

Flying on moonless nights and without any navigation equipment other than a map and compass, Lysanders would land on short strips of land, such as fields, marked out by 4 or 5 torches. They were only designed to carry one passenger in the rear cockpit, but in case of urgent necessity, two could be carried in extreme discomfort. In this manner, the pilots of No. 138 and, from early 1942, No. 161 Squadron delivered 101 and recovered 128 agents from Nazi occupied Europe.[3] The Lysanders were painted matt black and flew from secret airfields at Newmarket and later Tempsford, but used regular RAF stations to fuel up for the actual crossing, particularly RAF Tangmere.

[edit] Free French

The Lysander also joined the ranks of the Forces Aériennes Françaises Libres (Free French Air Force, FAFL) when Groupe Mixte de Combat (GMC) 1, formed at RAF Odiham on 29 August 1940, was sent to French North-West Africa in order both to persuade the authorities in countries like Gabon, Cameroon and Chad, which were still loyal to Vichy France, to join the Gaullist cause against the Axis powers, and to attack Italian ground forces in Libya. As with all FAFL aircraft, the Lysanders sported the Cross of Lorraine insignia on the fuselage and the wings, as opposed to the tricolor roundel first used in 1914, in order to distinguish their aircraft from those flying for the Vichy French Air Force. The Lysanders were mostly employed on reconnaissance missions but were also used to carry out occasional attacks. A total of 24 Lysanders was used by the FAFL.

[edit] Other duties

The type also filled other, less glamorous roles such as target-towing and communication aircraft. Two aircraft (T1443 and T1739) were transferred to British Overseas Airways Corporation (BOAC) for training and 18 were used by the Fleet Air Arm. All British Lysanders were withdrawn from service in 1946.

Export customers of the type included Finland (Mk I: 4, Mk III: 9), Ireland (Mk II: 6), Turkey (Mk II: 36), Portugal (Mk IIIA: 8), the United States (25), India (22) and Egypt (20). Egyptian Lysanders were the last to see active service, against Israel in the War of Independence in 1948.

A total of 1,786 were built, including 225 Canadian examples that were licence-built during the late 1930s.

A small number are preserved in museums in the UK and Canada and elsewhere. The National Air and Space Museum, Smithsonian Institution, in the Udvar-Hazy Center located in the Chantilly, Virginia, suburb of Washington DC near Dulles International Airport has a Westland Lysander IIIA on display, painted in the markings of No. 138 Squadron RAF (famed for their clandestine missions in wartime Europe).

A number of Lysanders are in museums in Canada including a Mk II (serial no. R9003) at the Canada Aviation Museum in Ottawa, Canada. This example is a composite of three aircraft and was restored by the RCAF as a Centennial project in 1967. A Mk IIIA (serial no. 2361) is in flying condition at the Canadian Warplane Heritage Museum in Ontario. It currently is painted in No. 400 "City of Toronto" RCAF Squadron markings. A Lysander IIIT was also on display at the Commonwealth Air Training Plan Museum, Brandon, Manitoba, Canada until July 2003 when it was disassembled and shipped to a museum in Portugal. Like many of the Lysanders that were retained in Canada as training aircraft, it was resplendent in bright "trainer" yellow.

The world's last airworthy Lysander is part of the Shuttleworth Collection based at Old Warden Airfield, Bedfordshire. It is a regular at several vintage airshows, including the Shuttleworth displays and "Flying Legends" at Duxford.

A Lysander Mk IIIT (serial no. 1589) is a Canadian-built trainer on display at the Indian Air Force Museum (IAFM) at Palam, New Delhi.
