2022: RTV-G-4 Bumper Rocket

The RTV-G-4 Bumper coupled a V-2 with a WAC Corporal second stage. The first six initial launches failed with the exception of launch five, which reached an altitude of 393 km. On July 24, 1950 at Launch Complex 3, Bumper 8 became the Cape’s first launch. The Bumper reached the upper atmosphere to meet the initial objective, but the flight was only partially successful as the second stage failed to ignite. Five days later, Bumper 7 launched from the Cape and was successful by reaching 5260 kph. Fragments from the blockhouse/launch control from this launch are on display at the Air Force Space & Missile Museum at Cape Canaveral Space Force Station.
