The Henschel Hs 294 was a guided air-to-sea missile developed by Henschel Flugzeug-Werke in Germany during World War II.

History and development:

Spoiler

The Henschel Hs 294 was a German guided anti‑ship missile project during World War II. It originated as a development of the Hs 293 glide bomb, with the goal of creating a weapon that could dive into the water and strike below a ship’s waterline. Work began around 1941 under Henschel Flugzeug‑Werke AG, led by Dr. Herbert Wagner.

The missile was about 6 meters long with a wingspan of 4 meters. It carried a warhead of roughly 630 kilograms and was powered by short‑burn rocket engines, usually the Walter HWK 109‑507. Guidance was radio‑controlled through the Kehl‑Straßburg system, and later experiments included television guidance. The design allowed the wings and rear fuselage to break away when the missile hit the water, letting the forward section continue underwater like a torpedo before detonating.

Testing took place between 1943 and 1944, with about 120 to 170 prototypes built in several variants. Contracts initially called for over a thousand units, but production was cut back as Germany’s war situation worsened. Trials showed promise but also revealed problems with propulsion reliability, guidance accuracy, and the difficult transition from air to water.

The Hs 294 never reached operational service. By late 1944, Germany lacked the resources and air superiority to deploy such advanced weapons. After the war, captured examples and documentation influenced Allied guided weapon programs, including the American BAT missile.

Could have two versions TV and non. Would be nice to see in naval.

As much as i think “funny wunderwaffen”, you wouldnt be able to balance it. Either it catapults the carrier platform to like 9.3, or you wont have proper GRB counter.

USA had tv gliding bombs in WW2.

Yeah yea, ya, super cool

I think it could be balanced around 7.0 by giving it a very bad camera, you would see basically something resembling an early black and white tv with quality getting reduced, stuttering and static as the distance from launching bomber increases

This Wunderwaffel will only work in Naval and Gaijin could balance it by giving Anti-Air AI the ability to try to intercept missile weapons like this.

The timeline for this is not correct. ASM-N-2 was developed from 1941 to 1944 and saw limited use in 1945. It is not possible for the USN to have operation paperclip scientists assist with development when the weapon was operational before V-E day.

And you would be pixel hunting for the enemy with the low resolution TV screen. On top of which, only broadcasted in green because it was a fed through a 7-inch green phosphor cathode ray tube. It would look similar to this playthrough of Minecraft, but at a way lower resolution.

+1 but how would it perform against tanks? Also how many of them could an He-177/Do-217 carry? It would be so fun to delete an IS-2 with a potato TV guided missile

I have a pdf of a book about the TV system that was planned for the HS 293D TV variant, test images included look like this:

If Gaijin can simulate the bad quality and signal related distortions well enough, i think hitting tanks from stand-off distances would indeed be pretty difficult since you wouldn’t know what you are looking at until you get too close to maneuver

Don’t forget the Allies where not sitting still they knew Germany had this tech and developed early EW tech to jam there signals and did deploy them on ships such as Battleship Texas. Some Warships would be immune from day one and could support near by friendly ships with a EW bubble. However the system would be turned off sometimes because it could mess up friendly equipment its not a get out of jail free card and it could be damaged.

The Germans also had basic ECCM on the Kehl–Straßburg system used for the HS-293 and Fritz-X, things like 20 different frequencies the receiver could cycle through if it lost signal and antenna designs that favored signals coming from above (bomber) rather than below (jamming ship). Germans also used deceptive “useless” signal bands that controlled nothing to make finding the right weapon control band and jamming it more difficult. So early jamming was never an “immunity”, just greatly decreased percentage of bombs that hit.

And finally the Hs 293B was developed which was wire guided, so immune to any jamming, although the Germans lost air superiority way before they could use this variant in combat, but it was successfully tested.

True jamming is not a magic get out of jail free card but its a balancer and Gaijin when they go into EW should not forget the early era. Also the Hs 294 is not a magic bullet with zero way to stop it and its use in ground battles would not be a issue because its a pure sea weapon would just shatter on impact.

Yeah I was referencing the American system for the GB4 which uses the RCA 1846 4.5 Iconoscope.

B variants do not have the TV camera, and the D variant that did was easily jammed because it broadcasted its TV camera on a 400MHz channel.

Yeah i wasn’t talking about the TV guided variant, just referencing anti jamming methods the Germans used and that finally wire guidance was developed. But who knows maybe they did consider wire guidance for the TV variant as well, someone needs to dig up the German archives lol

They could consider it all they want. There was no hardware available at the time to send the video feed back through a cable like the B variant. Fiber-optics did not become a thing til the late 70’s.

At worse

Here is the Iconoscope for the 294 and the 293D. FERNSEH GmbH Superikonoskop Type IS9 mm/12 . Interesting that both the GB4 and HS293/4’s Iconoscopes were used for regular TV broadcasting after the war.

I did some quick searching and apparently they had TV coax cables since 1927, and the Germans did consider cable guidance for the 293D but tests showed the thin cable used for guiding the B variant distorted the TV signal too much (a thicker cable would have worked, but would not be viable for mid-air reeling), and the war ended before more development could be made
