Lockheed SR-71 Blackbird
The
Lockheed SR-71 "Blackbird"
is a
long-range
,
Mach
3+
strategic
reconnaissance aircraft
that was operated by the
United States Air Force
. It was developed as a
black project
from the
Lockheed A-12
reconnaissance aircraft in the 1960s by
Lockheed
and its
Skunk Works
division. Renowned American aerospace engineer
Clarence "Kelly" Johnson
was responsible for many of the design's innovative concepts. During
aerial reconnaissance
missions, the SR-71 operated at high speeds and altitudes to allow it to outrace threats. If a
surface-to-air missile
launch was detected
, the standard evasive action was simply to accelerate and outfly the missile. The SR-71 was designed to have basic
stealth
characteristics and served as a precursor to future
stealth aircraft
.
