US Special Forces lost a helicopter in their mission to take down Osama bin Laden. And while previous reports - and a peek at the tail - have so far indicated that it was a Black Hawk MH-60, the latest speculation is that this wasn't just your average berzerker chopper.
It was a secret stealth edition. No wonder they burned that sucker to the ground.
According to Bill Sweetman at Aviation Week:
It was a secretly developed stealth helicopter, probably a highly modified version of an H-60 Blackhawk. Photos published in the Daily Mail and on the Secret Projects board show that the helicopter's tail features stealth-configured shapes on the boom and tip fairings, swept stabilizers and a "dishpan" cover over a non-standard five-or-six-blade tail rotor. It has a silver-loaded infra-red suppression finish similar to that seen on some V-22s.
The modifications Sweetman mentions include aerodynamic and flight control adjustments that allow for a reduced rotor speed (and, subsequently, less noise), radar cross-section reduction to improve jamming, and I'm sure other top-secret goodies.
Sweetman also mentioned that the highly sensitive technologies aboard the stealth Black Hawk indicate just how important this mission was to the US; allowing that bag of tricks to fall into Pakistani - or any other - hands would have been a sizable breach of defence intelligence. Fortunately, it appears that SEAL Team 6 succeeded in destroying the critical tech before the flew back to safety. [Aviation Week via PopSci]
