8 cze 2018 · Today the D-21 rides on the back of a Lockheed M-21, a specialized variant of the SR-71 Blackbird, the famous Mach 3+ high altitude spy plane.
15 wrz 2021 · The result was the supersonic D-21, capable of flying at more than 2,200 mph, with a 90,000-foot flight ceiling. It bore a close resemblance to the A-12 Oxcart reconnaissance aircraft, also developed by Lockheed.
29 mar 2019 · The D-21 technology developed in the 1962-1971 timeframe and the borrowed technology from the U2, A12, and SR71 reconnaissance aircrafts created a drone that the world had never seen. These advances in drone technology laid the ground work for the drone of the future.
20 mar 2019 · The drone’s incredible performance owed to the Marquardt Ramjet engine, but by choosing this means of propulsion, Lockheed was forcing the need to mount the D-21 on and launch from its Mach 3-capable A-12, which was just beginning testing in 1962.
The Lockheed D-21 was a highly-advanced, remotely piloted aircraft (RPA) designed to carry out high-speed, high-altitude strategic reconnaissance missions over hostile territory. Developed by the famed Lockheed "Skunk Works” in the 1960s, the D-21 used,
