Ruhrstahl X-7

The Ruhrstahl X-7, nicknamed Rotkaeppchen (Little Red Riding Hood) and also called the Kramer X-7 or Ruhrstahl-Kramer RK 347, was a German wire-guided anti-tank guided missile with manual command guidance, developed during World War II. Ruhrstahl AG began work in 1943 under Max Otto Kramer after the Waffenamt placed an urgent order, because weapons such as the Panzerfaust and Panzerschreck were only effective at very short range. It was essentially a smaller, solid-fuel version of the X-4 air-to-air missile, with two solid rocket stages, a 2.5 kilogram hollow-charge warhead and a range of roughly 1,000 to 1,200 metres. Seven were test-fired at the Sennelager Training Area on 21 September 1944. A few hundred were built, mostly for testing, and a few may have been used on the Eastern Front in 1945, though the article lists it as never deployed. It pioneered postwar anti-tank missiles, and France built an improved version in 1955 as the SS.10.
