Boost-glide

Subtopics

Saenger Antipodal Bomber German sled-launched intercontinental boost-glide missile. Saenger-Bredt antipodal bomber - sled launched, boosted to suborbital velocity, 'skips' off upper atmosphere to deliver bomb load on target, recovery back at launch site. Fascinated Stalin, led to US Dynasoar project. Post-war, Saenger designed two-stage HTOHL space shuttles in Germany.

A9/A10 German intercontinental boost-glide missile. The A9/A10 was the world's first practical design for a transatlantic ballistic missile. Design of the two stage missile began in 1940 and first flight would have been in 1946. Work on the A9/A10 was prohibited after 1943 when all efforts were to be spent on perfection and production of the A4 as a weapon-in-being. Von Braun managed to continue some development and flight tests of the A9 under the cover name of A4b (i.e. a modification of the A4, and therefore a production-related project). In late 1944 work on the A9/A10 resumed under the code name Projekt Amerika, but no significant hardware development was possible after the last test of the A4b in January 1945.

A-4b German intermediate range boost-glide missile. Winged version of the V-2 missile with over double the range. Two flown at the end of the war, but there was no time to complete development, let alone start production.

Keldysh Bomber Russian intercontinental boost-glide missile. Soviet version of the Saenger antipodal bomber intensely studied on Stalin's direct orders in 1946-1947. The final study concluded that, given the fuel consumption of foreseeable rocket engines, the design would only be feasible using ramjet engines and greatly advanced materials. This meant that development could only begin in the late 1950's, when such technologies were available. By that time the design had been superseded by more advanced concepts.

KR Russian intercontinental boost-glide missile. The KR (winged rocket) was a three-stage unmanned boost-glide missile developed at the Tupolev's OKB-156. Work began in 1957. Two alternates were considered for the first stage: a conventional liquid rocket or a special manned aircraft launcher. The second stage was a conventional rocket. The final winged stage included a propulsion section and nuclear warhead. The glider would cut-off at an altitude of 50 km and a velocity of 20,000 km/hr. Planned-over target speed was 7,000 km/hr at 30 km altitude. Work on the project continued only about a year before it was abandoned in favor of the more conventional Tu-123 supersonic cruise missile. The KR would have had a gross weight of 240 metric tons, and delivered a payload of 3 to 5 metric tons over a range of 9,000 to 12,000 km.

Tu-130 Russian intercontinental boost-glide missile. Three-stage intercontinental boost-glide missile. Studied 1957-1960.

Tu-123 Russian intercontinental boost-glide missile. Exotic design for an intercontinental missile using a gas core fission reactor for cruise propulsion. Studied circa 1957.

UR-200A Russian intercontinental boost-glide missile. Version that would boost the Raketoplan combat re-entry vehicle, which would use aerodynamic horizontal and vertical maneuvering to penetrate enemy space defenses and be practically invulnerable.
