Hs 293

Hs 293. The Henschel Hs 293 was a pioneering German anti-ship missile developed and deployed during World War II. Designed by Professor Herbert A. Wagner and manufactured by Henschel & Son, it was one of the world's first operational guided missiles, representing a significant technological leap in stand-off weaponry. Primarily launched from medium bombers like the Dornier Do 217 and Heinkel He 177, it was used extensively against Allied shipping in the Mediterranean Sea and the Atlantic Ocean.

Development and design

The development of the Hs 293 stemmed from pre-war research into glide bombs, with the project initiated at Henschel & Son under the leadership of Herbert A. Wagner. The design evolved from the earlier unpowered Henschel Hs 294, integrating a Walter HWK 109-507 liquid-fuel rocket motor to extend its range and maintain airspeed after release. Guidance was achieved through a MCLOS (manual command to line of sight) system, where an operator in the launch aircraft used a Kehl-Straßburg radio command link to steer the weapon by visually tracking its flare. The airframe consisted of a standard SC 500 bomb body fitted with wings, a tail assembly, and the underslung rocket motor, creating a distinctive cruciform shape.

Operational history

The Hs 293 entered operational service with the Luftwaffe in mid-1943, achieving its first major success on August 25, 1943, by severely damaging the British sloop HMS Bideford and sinking the corvette HMS Egret during an attack in the Bay of Biscay. It saw extensive use in the Mediterranean Sea, where units like II. Gruppe, Kampfgeschwader 100 launched attacks against Allied invasion forces during the Allied invasion of Sicily and the Allied invasion of Italy. Notable engagements included the sinking of the troopship HMT Rohna in November 1943 and attacks on warships during the Battle of Anzio. Despite these successes, increasing Allied electronic warfare countermeasures, particularly jamming of the Kehl-Straßburg radio frequencies by systems like American Naval Research Laboratory's "Foxer", along with effective fighter cover from the Royal Air Force and United States Army Air Forces, significantly degraded its effectiveness by late 1944.

Technical specifications

The Hs 293 had a launch weight of approximately 1,045 kg, with a 295 kg TNT warhead derived from the SC 500 bomb. Its overall length was 3.82 meters, with a wingspan of 3.10 meters. Propulsion was provided by a single Walter HWK 109-507 rocket engine, generating 5.9 kN of thrust for about 10 seconds, enabling a maximum speed of roughly 260 m/s. Operational range was up to 12 kilometers when launched from an altitude of 1,400 meters. The guidance system relied on the Kehl-Straßburg radio command link operating on the FuG 203 and FuG 230 units, with the operator using a Joystick to transmit steering commands.

Variants

Several variants of the Hs 293 were developed to improve performance or test new guidance methods. The Hs 293A-1 was the initial production model, while the Hs 293B was proposed with wire guidance to counter radio jamming. The Hs 293C featured a modified warhead for underwater explosion, and the Hs 293D was an experimental model intended for television guidance. The Hs 293F was a tailless, wing-only design, and the Hs 293H was a concept for an air-to-air variant. Further developments included the larger Henschel Hs 294, designed for underwater travel, and the Fritz X, a different armor-piercing, unpowered guided bomb used by the same units.

Operators

The sole operational operator of the Hs 293 was the air force of Nazi Germany, the Luftwaffe. It was primarily deployed by specialized anti-shipping squadrons, most notably Kampfgeschwader 100 and elements of Kampfgeschwader 40 and Kampfgeschwader 26. These units operated from bases in occupied France, Norway, and the Mediterranean region, launching the weapon from modified medium bombers such as the Dornier Do 217, Heinkel He 111, Heinkel He 177, and the Focke-Wulf Fw 200 Condor. No other nation used the Hs 293 operationally during the war, though captured examples were studied extensively by the United States and the Soviet Union in the post-war period.
