Supposition of the secret stealth Blackhawk which crashed during the Osama Bin Laden raid.
At the moment there are only photos of the tail of the crashed helo and some hypothetical renderings and sketchs (some of this sketches are quite unrealistic).
The possibly aspect of mh60 Stealth has hard edges stealth look as F117, top air intake with diamond shape like Comanche helicopter project, exhaust pipes at the end of tailboom for low thermal signature, high tech carbon fiber surfaces and paint like f22 for radar waves absorbing.
This model is only artistic representation of the subject matter. I made it for a flight magazine illustration.
One of two specially modified MH-60s used in the raid on Osama bin Laden's hideout in Pakistan on 1 May 2011 was damaged in a hard landing, and was subsequently destroyed by US forces. Subsequent reports state that the Blackhawk destroyed was a previously unconfirmed, but rumored, modification of the design with reduced noise signature and stealth technology. The modifications are said to add several hundred pounds to the base helicopter including edge alignment panels, special coatings and anti-radar treatments for the windshields.
