Imagine This: A Mach 6 SR-71 Blackbird (That Has Strike Capabilities)
Could this come to pass?
by Harold C. Hutchison
According to a report by Popular Mechanics, the SR-72 will also have a strike mission.
The Lockheed SR-71 Blackbird is rightly viewed as a legend. Best known as a recon plane that nobody could hit , it even was considered as the basis for a fighter and was the second-fastest manned plane in history.
It served with the United States military from 1964-1998, and with NASA until 1999. The SR-71 had been developed from the A-12 OXCART (no relation to the A-12 Avenger ), a single-seat plane capable of making high-speed recon runs as well.
