The helicopters that flew the Navy SEALs on the mission to kill Osama bin Laden were a radar-evading variant of the special operations MH-60 Black Hawk, according to a retired special operations aviator. The helicopter’s low-observable technology is similar to that of the F-117 Stealth Fighter the retired special operations aviator said. “It really didn’t look like a traditional Black Hawk,” he said. It had “hard edges, sort of like an … F-117, you know how they have those distinctive edges and angles — that’s what they had on this one.” In addition, “in order to keep the radar cross-section down, you have to do something to treat the windshield,” he said. If a special coating was applied to the windshield it is “very plausible” that would make the helicopter more difficult to fly for pilots wearing night-vision goggles, he said. Here’s yet another shot of the bird’s tail. <http://images.defensetech.org/wp-content/uploads/2011/05/U.S.-special-forces-assau-01.jpg> According to Naylor’s piece, the modifications made to make the chopper stealthy could have contributed to the crash: That crash landing might have been caused by a phenomenon known as “settling with power,” which occurs when a helicopter descends too quickly because its rotors cannot get the lift required from the turbulent air of their own downwash. “It’s hard to settle with power in a Black Hawk, but then again, if they were using one of these [low-observable helicopters], working at max gross weight, it’s certainly plausible that they could have because they would have been flying so heavy,” the retired special operations aviator said, noting that low-observable modifications added “several hundred pounds” to the weight of the MH-60, which already weighs about 500 to 1000 pounds more than a regular UH-60 Black Hawk. Maybe this is a stealthed out MH-60 but I still think the modification required may hint at a basically new aircraft. More on this later. I want to see a full on bird. Here are some additional details from Naylor’s story: This was to be expected, the retired special operations aviator said. “Certain parts of the fuselage, the nose and the tail had these various almost like snap-on parts to them that gave it the very unique appearance,” he said. He and another source referred to the disc-shaped device that is seen covering the tail rotor in the photographs as a “hubcap.” If the radar-evading technology worked, it “would be a true statement” to say that the use of the low-observable Black Hawks was evidence that the United States gave Pakistani authorities no advance warning of the mission, the retired special operations aviator added. The low-observable program started with AH-6 Little Bird 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 F-117, to refine the radar-evading technology and apply it to the 160th Special Operations Aviation Regiment’s MH-60s, he said. USSOCOM 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. USSOCOM 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. “I don’t know if it was for money or if it was because the technology was not achieving the reduction in the radar cross-section that they were hoping for,” he said. In the meantime, MH-60 Black Hawk crews from the 160th’s 1st Battalion, headquartered at Fort Campbell, Ky., would rotate to Nevada to train on the stealthy aircraft, he said.
