[edit] History

The Hs 293 project was started in 1940, based on the "Gustav Schwartz Propellerwerke" pure glide bomb which was designed in 1939. The Schwartz design did not have a terminal guidance system, instead it used an autopilot to maintain it on a straight course. The intention was that it could be launched from a bomber at sufficient distance to be out of range of anti-aircraft fire. Henschel developed it the following year to add a rocket motor underneath it to allow it to be used from lower altitude and to increase the range.

Although designed for use against ships, it was also used in Normandy in early August 1944 to attack bridges over the River See and River Selume. However, only one bridge was slightly damaged but 6 aircraft were lost[1].

[edit] Variants

Hs 293A. The original version.

Hs 293B was wire guided to prevent jamming; it was never put into production, because jamming was never serious enough to prevent the radio-guided version from being effective.

Hs 293C had a detachable warhead (designated when it entered production Hs 293A-2, making the original version Hs 293Ato be changed to Hs 293A-1)

Hs 293D was television-guided. 20 were built and tested. It was never used operationally as the television equipment was unreliable.

Hs 293E an experimental model to test spoiler controls as a replacement to ailerons; never put into series production. This modification was put into the final version of the Hs 293A-2 but by then the Luftwaffe had no aircraft available for anti-shipping operations and it was never deployed.

Hs 293F a tailless variant; never got further than the design phase.

Hs 293H an experimental variant designed to be launched from one aircraft and controlled from another. Abandoned because allied air superiority had reached the point where it was felt that the second aircraft would be unable to remain in the vicinity of the ship for long enough.

Hs 293V6 designed for launch from the Arado Ar 234 jet bomber travelling at 200 metres per second. The main change was reducing the wing span of the missile to allow it to be carried within the aircraft. The missile did not proceed past the design stage.

[edit] Inventory

Over 1000 were built, from 1942 onwards.

[edit] Combat Performance

The Hs 293 was intended to destroy unarmoured ships. (Compare with the Fritz X, which was intended for use against armoured targets).

One drawback of the Hs 293 was that, after the missile was launched, the bomber had to fly in a straight level path, and thus could not manoeuvre to evade anti-aircraft guns.

On August 27, 1943, an Hs 293 was used in the first successful attack by a guided missile, sinking the British sloop HMS Egret. On November 26 of that year an Hs 293 caused the sinking of the HMT Rohna.
