The SR-71 was one of the most groundbreaking military aircrafts of all times. Designed by Kelly Johnson – the legendary aircraft designer for Lockheed who also designed the U2 spy plane, the SR71 was developed to be the ultimate spy plane. It had a cruising speed of over 3.2 Mach – fa...
The SR-72 unmanned aircraft will be powered by two engines. The aircraft will receive thrust from the turbine engine until it reaches a speed of Mach 3, while the dual-mode ramjet will deliver power for the flight at hypersonic speeds. The aircraft will use a single inlet nozzle for both ...
Lockheed Martin’s Skunk Works is proposing to develop a new aircraft for intelligence, surveillance and reconnaissance (ISR) missions that is capable of Mach 6.0 flight, or nearly twice the top speed of the long-retired SR-71 Blackbird.
The SR-72 hypersonic unmanned reconnaissance aircraft is mainly used to replace the SR-71 "Blackbird" high-speed high-altitude reconnaissance aircraft developed in the 1970s, and its maximum flight speed will reach an astonishing Mach 6 (i.e., six times the speed of sound), which is twice ...
Lockheed’s SR-71 Blackbird first flew in 1964 and was decommissioned in 1999. Not known until the mid nineties is that the SR-71 was developed from the top secret Lockheed A-12. The A-12, project Oxcart, was build for the CIA as high speed and high alti
It is a disruptive technology and will enable various platforms to operate at two to three times the speed of the Blackbird... Security classification guidance will only allow us to say the speed is greater than Mach 5." Playback cannot continue. No available working or s...
To reach Mach 6, the SR-72 will use an engine that acts like a normal jet turbine until speeds of Mach 3 are reached but which then operates like a ramjet to accelerate beyond that. "Speed is the next aviationadvancement6to counter emerging threats in the next several decades," said Bra...

The unmanned SR-72 will use an engine that combines a turbine and a ramjet(冲压式喷气发动机)to reach its top speed of Mach 6-about 3,600mph (5,800km/h). Like its predecessor,the SR-72 will be designed for highaltitude surveillance but might also be fitted with weapons to strike targe...
