The low-observable program started with

special operations attack helicopters in the 1980s, said the aviator. During the 1990s U.S. Special Operations Command worked with the Lockheed-Martin Skunk Works division, which also designed the

awarded a contract to Boeing to modify several MH-60s to the low-observable design "in the '99 to 2000 timeframe," he said.Initial plans called for the low-observable Black Hawks to be formed into a new unit commanded by a lieutenant colonel and located at a military facility in Nevada, the retired special operations aviator said. "The intent was always to move it out west where it could be kept in a covered capability," he said.

planned to assign about 35 to 50 personnel to the unit, the retired special operations aviator said. "There were going to be four [low-observable] aircraft, they were going to have a couple of 'slick' unmodified Black Hawks, and that was going to be their job was to fly the low-observables."SOCOM canceled those plans "within the last two years," but not before at least some of the low-observable helicopters had been delivered to the Nevada facility, the retired aviator said.

variant known as the Direct Action Penetrator, which is equipped with stub wings upon which can be fitted a variety of armaments.The early versions of the low-observable Black Hawks were not fitted with air-to-air refueling probes, the retired special operations aviator said.
