SR-71 Blackbird
The SR-71 Blackbird was a Reconnaissance aircraft designed for the CIA to operate at high speeds and high altitudes to avoid enemy air defenses. The blackbird had also seen operations with the Airforce and NASA. It achieved speech of Mach 3.2 and altitudes above 85,000 feet so, with a combination of jamming made it an extremely difficult plane to target with surface-to-air missiles. In total 32 SR-71s were built but not a single one was lost due to enemy air defenses. The SR-71’s role as a surveillance aircraft today has been replaced by satellites and UAVs. The SR-71 program was needed to replace the slow U-2 surveillance aircraft and aimed to fly higher and faster, while also having a lower radar cross-section. Most of the airframe was built of titanium due to the high heat it would face at extreme speeds. Due to such drastic differences in materials from usual aircraft manufacturing, there was special tool...
