Q Branch - Lockheed Martin-Boeing
TierIII Minus Low-Observable UAV DarkStar
In
late 1995 Lockheed Martin and Boeing revealed details of their highly secret UAV
(Unmanned Aerial Vehicle) codenamed 'DarkStar'. It made its public debut
at Lockheed's 'Skunk Works' at Palmdale, Cal. on 1 June, 1996. Ham radio
enthusiasts, meanwhile, had tuned to a frequency used by an AWACS E-3 aircraft
in 1992 and identified callsigns 'Dark Star Mike' and 'November', possibly used
in a Dark Star test.
DarkStar is a high-altitude, low-observable endurance UAV optimized for
reconnaissance in highly defended areas. The UAV is capable of travelling 500
miles to an operational point, and operating for over 8 hours at 45,000 feet.
It is powered by a 1,900 lb. thrust Rolls Royce F129 (FJ44) turbofan in a graphite-based
structure. It is capable of independent takeoff, cruise and landing procedures.
In
September 1995 the first DarkStar was ready to move to NASA-Dryden at Edwards
AFB, Cal. for tests. The prototype crashed in 1996 and a second version was ready
to operate in 1997. It made its first successful flight in June 1998. This marked
the the restart of a test program to evaluate basic system performance, including
the high-resolution synthetic aperture radar (SAR) and electro-optical (EO) payloads.
Designed to be fully autonomous, the DarkStar can take off, fly to the
target area, operate its sensors, transmit its sensor imagery, return to base
and land without human intervention. The DarkStar can operate in all weather
and has stealth properties making detection difficult. It uses a digital link
to transmit images directly to the ground station or to satellites. It can send
close-up images to battlefield commanders, and work in conjunction with the longer
endurance Global Hawk
UAV, the E-3 AWACS and E-8 JSTARS.
