When you look at the Lockheed F-104 Starfighter, this is a plane that looks like it could be a rocket from some sci-fi movie or show from the old days. In some ways, it was. According to MilitaryFactory.com, the F-104 had a top speed of 1,320 miles per hour. This was about 173 percent of the speed of sound. But there was one minor hiccup. The F-104 needed a lot of runway to take off, mostly because its wings were small. Okay, on the puny side.
This causes a quandry. One big concern was that the Soviet Union would be able to get control of the air by hitting the runways on the airbases. The United States began testing Zero-Length Launches (ZeLL) with the F-100 Super Sabre. According to The Aviationist, West Germany also was looking into this concept. They had a good reason to do so. They were likely to be on the front lines, and airfields were not only threatened by bombers, but also by fighters and missiles.
ZeLL was accomplished by use of a big, powerful rocket that was installed on the plane. The F-104 was a natural as it was intended to be a point-defense interceptor. West Germany had bought a lot of these planes as multi-role fighters (which resulted in a big investigation as the F-104's manufacturer had… well, let's just say some money changed hands).
Germany had used rocket-powered interceptors, like the Me-163 Komet in World War II. The planes hadn't worked well. Still, the Germans gave the ZeLL-equipped F-104 a shot. By 1966, though, the West Germans, as America had earlier, gave up on the idea. But the United Kingdom would solve the problem by developing the V/STOL jet known as the Harrier. That plane would later prove to be a decisive factor in the British winning the Falklands War. And it all started with using rockets to throw fighters into the air.
