Fritz X – an unpowered air-launched, MCLOS-guided anti-ship missile using the FuG 203/230 Kehl-Straßurg control system, the pioneering wartime example of a gravity-type PGM, used from September 1943 through 1944.

Credit: Michael.katzmann at English Wikipedia This guided anti-ship glide munition (see main image at the top) was one of Hitler’s most secret bombs. And it’s not hard to see why. Not only was it the first precision-guided bomb to ever be deployed in combat, but on 9 September 1943 it also became the first such bomb to sink a ship in combat – the Italian battleship Roma. Neufeld, Michael (13 April 2020). "The Myth of the German "Wonder-Weapons" ". Smithsonian National Air and Space Museum . Retrieved 19 April 2020.As the war situation worsened for Germany from 1942, claims about the development of revolutionary new weapons which could turn the tide became an increasingly prominent part of the propaganda directed at Germans by their government. [2] In reality, the advanced weapons under development generally required lengthy periods of design work and testing, and there was no realistic prospect of the German military being able to field them before the end of the war. When some advanced designs, such as the Panther tank and Type XXI submarine, were rushed into production, their performance proved disappointing to the German military and leadership due to inadequate pre-production testing or poorly planned construction processes. [3] Historian Michael J. Neufeld has noted that "the net result of all these weapons, deployed or otherwise, was that the Reich wasted a lot of money and technical expertise (and killed a lot of forced and slave laborers) in developing and producing exotic devices that yielded little or no tactical and strategic advantage". [4] However, a few weapons proved to be successful and have had a large influence in post-war designs.

Landkreuzer P. 1500 " Monster" – a proposed super-heavy self-propelled gun, weighing 1500 metric tons and armed with the 800mm Schwerer Gustav/Dora gun. Panzerkampfwagen E-100 –A planned super-heavy tank (the heaviest of a series of "E-tanks") weighing 140 tonnes and armed with either 128 or 150mm cannon, one prototype hull nearly completed, the hull was later captured and evaluated by the British before being scrapped in the 1950s. Fritz X, a guided anti-ship glide bomb, the world's first precision guided weapon ever deployed in combat. Henschel Hs 293 – a pioneering MCLOS-guided, launch-boosted air-to-ship missile using the Kehl-Straßurg radio link as with the Fritz X, used in combat from 1943 to 1944.
