It was developed and manufactured by Airspeed Limited, alongside various subcontractors; the type was named after Horsa, the legendary 5th-century conqueror of southern Britain.
Having been greatly impressed by the effective use of airborne operations by Germany during the early stages of the Second World War, such as during the Battle of France, the Allied powers sought to establish capable counterpart forces of their own.
The British War Office, determining that the role of gliders would be an essential component of such airborne forces, proceeded to examine available options.
In the early stages of the Second World War, the German military demonstrated its role as a pioneer in the deployment of airborne operations.
[4] On 22 June 1940, the British airborne establishment was formally initiated when the Prime Minister, Winston Churchill, directed the War Office in a memorandum to investigate the possibility of creating a corps of 5,000 parachute troops.
It was believed that airborne troops should be landed in larger groups than the eight that the Hotspur could carry, and that the number of towplanes required would prove to be impractical.
Even the controls in the cockpit were masterpieces of the woodworker's skill.Airspeed assembled a team headed by aircraft designer Hessell Tiltman[13][14] whose efforts began at the de Havilland technical school at Hatfield, Hertfordshire, before relocating to Salisbury Hall, London Colney.
"[citation needed] The initial 695 gliders were manufactured at Airspeed's factory in Christchurch, Hampshire;[17] production of the remainder was performed by an assortment of subcontractors.
The Horsa Mk II had been specifically designed for the carriage of vehicles, featuring a reinforced floor and a hinged nose section in order to accommodate such use.
Other changes included the adoption of a twin nosewheel arrangement, a modified tow attachment and an increased all-up weight of 15,750 lb (7,140 kg).
As a consequence of the majority of subcontractors not having available airfields from which to deliver the gliders, they sent the sub-assemblies to RAF Maintenance Units (MUs), who would perform final assembly themselves; this process has been attributed as being responsible for the widely varying production numbers recorded of the type.
It was capable of transporting a maximum of 30 seated fully equipped troops; it also had the flexibility to carry a Jeep or an Ordnance QF 6-pounder anti-tank gun.
[25] The fuselage joint at the rear end of the main section could be broken on landing to facilitate the rapid unloading of troops and equipment, for which ramps were provided.
On operational flights, the main gear could be jettisoned and landing was then made on the castoring nose wheel and a sprung skid set on the underside of the fuselage.
[13] Initially, the cockpit would be outfitted with internal telephone systems that allowed for communication between the pilots of the glider and tug aircraft while connected; however, this was replaced on later-built models by radio sets instead, which had the advantage of being able to maintain contact after detaching.
[citation needed] During March 1942, the Airborne Forces Experimental Establishment and 1st Airlanding Brigade commenced loading trials using several of the prototypes, but immediately ran into problems.
The two Horsa gliders, each carrying 15 sappers, and one of the Halifax tug aircraft crashed in Norway due to bad weather.
[17] In preparation for further operational deployment, 30 Horsa gliders were air-towed by Halifax bombers from bases in Great Britain to North Africa; three of these aircraft were lost in transit.
The first unit to land in France during the battle was a British coup-de-main force, carried by six Horsas, that captured the Caen canal and Orne river bridges.
[28] The United States Army Air Forces (USAAF) acquired approximately 400 Horsas in a form of reverse Lend-Lease.
[20] A small number of Horsa Mk IIs were obtained by the Royal Canadian Air Force (RCAF) and participated in evaluation trials which were held at CFB Gimli, Manitoba.
Ten replicas were built for the 1977 film A Bridge Too Far, mainly for static display and set-dressing, although one Horsa was modified to make a brief "hop" towed behind a Dakota at Deelen, the Netherlands.
[38] A fuselage section displayed at the Traces of War museum at Wolfheze, Netherlands, was retrieved from Cholsey, Oxfordshire, where it had served as a dwelling for over 50 years.
BAPC.232 Horsa I/II Composite – Nose & Fuselage sections is on display in the Walter Goldsmith Hangar at the de Havilland Aircraft Museum.
