Airspeed AS.51 Horsa — Military Transport Glider / Airborne Assault / Troop Transport
Open in interactive gallery →

The Airspeed AS.51 Horsa was the principal British WWII assault glider — a wood-and-fabric troops-carrying glider built to deliver airborne soldiers and light vehicles directly to drop zones behind enemy lines. Airspeed and several subcontractors built 3,799 Horsas between 1941 and August 1945. The Horsa flew major British and Allied airborne operations: D-Day Pegasus Bridge capture (the first Allied troops on French soil on 6 June 1944), Operation Tonga (Normandy paratroop drop), Operation Market Garden (Arnhem, September 1944), and Operation Varsity (Rhine crossing, March 1945).

The Horsa was an all-wood high-wing glider with twin tail fins. The aircraft had no engine; it was towed aloft by a tug aircraft (typically Halifax, Albemarle, Stirling, or Dakota) at 100-130 mph. Maximum towing speed 150 mph; gliding speed 80-85 mph. Crew: 2 pilots. Capacity: 25 fully-equipped troops or a combination of vehicles + troops (light truck + 14 troops, or one universal carrier + 13 troops, or one 6-pounder anti-tank gun + 7 crew). Wingspan 88 ft; gross weight 15,500 lb. The aircraft had a single hinged door on the port side; some Mk II Horsas added a hinged nose for direct vehicle drive-out.

The Horsa's most-celebrated mission was Pegasus Bridge — six Horsas of 6th Airborne Division landed near the Caen Canal bridge between 0016 and 0020 hours on 6 June 1944, capturing the bridge intact 5 hours before the seaborne D-Day landings. The Horsa was also the principal British glider at Arnhem (Operation Market Garden, 17-26 September 1944), where about 320 Horsas delivered 1st Airborne Division troops to landing zones west of Arnhem. The operation became famous after the controversial "bridge too far" defeat. About 600 Horsas were lost in WWII operations — about 16% of total production.

Production ended in August 1945. About 1 Horsa airframe survives in 2026 — a partial composite reconstruction at the Imperial War Museum Duxford. No Horsa is airworthy. The Horsa is one of the most-iconic WWII assault gliders despite (or perhaps because of) its losses; the type's wood-and-fabric construction did not survive post-war scrapping campaigns.

For Kids — a shorter, friendlier version

The Airspeed Horsa was a British glider used in World War Two. It had no engine at all. A tug plane would tow it into the sky, then release it. The pilots would glide it down to land troops right where they were needed.

The Horsa was made mostly of wood and fabric. It had a high wing and twin tail fins. Two pilots flew it from the front. It could carry up to 25 fully-equipped soldiers. That is a lot of people for a plane with no engine!

The Horsa was bigger than a school bus in wingspan. Its wings stretched 88 feet wide. It could also carry light vehicles, like small trucks or anti-tank guns. Some Horsas had a hinged nose so vehicles could drive straight out after landing.

The Horsa took part in some very important missions. On D-Day in 1944, Horsas helped capture Pegasus Bridge in France. They also flew in Operation Market Garden near Arnhem and the Rhine crossing in 1945. These missions helped Allied troops move fast and by surprise.

Almost 3,800 Horsas were built between 1941 and 1945. Many different factories worked together to build them all. The Horsa played a big part in helping Allied forces win key battles in Europe.

Fun Facts

  • The Horsa had no engine — it was towed into the sky like a giant kite!
  • Its wings were 88 feet wide, bigger than many powered planes of its time.
  • Nearly 3,800 Horsas were built during World War Two.
  • The Horsa could carry a small truck and 14 soldiers all at once.
  • It was made mostly of wood, like a flying shed!
  • Horsa pilots could only land once — the glider was not built to take off again on its own.
  • On D-Day, Horsa gliders landed troops to capture Pegasus Bridge before dawn.
  • The top towing speed was 150 miles per hour, faster than most cars on a highway today.

Kids’ Questions

How did the Horsa get into the air with no engine?

A tug plane, like a Halifax or Dakota, would pull the Horsa into the sky with a long tow rope. Once the glider reached the right place, the rope was released. The pilots then glided it down to land.

What could the Horsa carry inside?

The Horsa could carry up to 25 fully-equipped soldiers. It could also carry light vehicles like small trucks or anti-tank guns with their crews. Some had a hinged nose so vehicles could drive straight out after landing.

Why were gliders used instead of regular planes?

Gliders were quiet and could land in small fields far behind enemy lines. They could drop off lots of soldiers and equipment right where they were needed. This gave Allied forces the element of surprise.

What famous mission did the Horsa fly on D-Day?

On June 6, 1944, Horsas carried British soldiers to capture Pegasus Bridge in France. These troops were among the very first Allied soldiers to land in France that day. It was a very important mission early on D-Day.

Variants

Horsa Mk I
Standard production. About 3,650 built. Single hinged port-side door for troop exit.
Horsa Mk II
Improved variant with hinged nose for direct vehicle drive-out. About 149 built. Used in late-WWII operations including Operation Varsity.

Notable Operators

Royal Air Force / Glider Pilot Regiment
Primary user. RAF towed the Horsas; Glider Pilot Regiment army personnel flew them. Principal operations: Pegasus Bridge (June 1944), Arnhem (September 1944), Rhine crossings (March 1945).
U.S. Army Air Forces
About 350 Horsas operated by the U.S. 9th Troop Carrier Command alongside Waco CG-4A gliders for D-Day and Arnhem operations.

Frequently Asked Questions

What was Pegasus Bridge?

The Caen Canal bridge captured by British 6th Airborne Division gliders on 6 June 1944 — the first Allied troops on French soil on D-Day. Six Horsas landed near the bridge between 0016 and 0020 hours and captured it intact 5 hours before the seaborne landings began. The mission is depicted in The Longest Day (1962) and is one of the most-celebrated airborne operations of WWII.

How many troops did a Horsa carry?

25 fully-equipped troops, or a combination of vehicles + troops: light truck + 14 troops, or one universal carrier + 13 troops, or one 6-pounder anti-tank gun + 7 crew. The Mk II hinged-nose variant could direct-drive a Jeep or other small vehicle out of the front of the glider after landing.

What aircraft towed the Horsa?

Halifax, Albemarle, Stirling, and Dakota (C-47) tug aircraft were all used. Tow speed was typically 100-130 mph; the Horsa would release at the target area altitude (typically 2,000-4,000 ft) and glide silently to the landing zone.

How many Horsas were built?

3,799 airframes between 1941 and August 1945. Production was at Airspeed (Portsmouth) and a network of subcontractors (Harris Lebus, Austin Motors, etc.). The all-wood construction simplified production by using furniture-industry workers and small workshops.
