Heeresversuchsanstalt Peenemünde
The V-1 flying bomb was the first cruise missile ever built. It was built in the Peenemünde Army Research Center and first tested in 1942. The V-1 was intended to target London and was massively fired, achieving more than one hundred launches a day. The V-1 was launched from a rail system to achieve the speed needed to operate its pulsejet engine and would achieve a 250 kilometers radius, at one point flying at 640 km/h.
