The Army did not ultimately pursue the Advanced Quick Fix system, and the helicopter to go with it, on a widespread basis, a fate that befell many U.S. military programs in development right around the collapse of the Soviet Union in 1991.Based on what we know, it is very plausible that this photograph was taken sometime in the late 1980s or more likely the 1990s. "You wouldn't know that it was coming right at you. Under the fuselage, it appears to have the long, retractable whip antenna found on the EH-60A, versus the more robust antenna system found on the EH-60L. We are constantly on the lookout for more details about the U.S. military's highly elusive stealthy Black Hawk helicopters, one of which famously It is our understanding that the picture in question seen at the top of this story and again below in a slightly enhanced manner, has a relation to Fort Eustis in Virginia. Neighbors of bin Laden in Abbottabad, Pakistan, told ABC News they didn't hear the helicopters the night of the Sunday raid until they were directly overhead. This is not to be confused with EUH-60L helicopters configured as airborne command posts. Pentagon officials could have misconstrued older tests with more basic kits with a far more elaborate configuration used on the raid. "This is a first," he said.

The narrow cockpit causes the pilot and copilot seats to be spaced closer to each other; space for four-across seating in the main cabin is decreased. The EH-60As would eventually replace older EH-1H helicopters equipped with the AN/ALQ-151 and AN/ALQ-151(V)1 Quick Fix suites.A low-quality picture of one of the 10 EH-1Xs built for the Army before work shifted to the EH-60A. How did they do it?One answer, experts believe, is that the special operations team used previously unseen stealth helicopters.The evidence for this comes from images of the wreckage of one of the helicopters, which departing Seals destroyed after it crash landed in the compound.The tail of the top secret aircraft survived, providing a treasure chest of clues for aviation experts.After some detective work, these experts have concluded it was a UH-60 Blackhawk, heavily modified to make it quieter and less visible to radar.They are confident the raid marks the first time that a stealth helicopter has been used operationally.It wouldn't be the first of its kind in existence, however. Later model UH-60As and UH-60Ls, as well as other H-60 variants based on those versions, also have infrared reduction fairings over their exhausts that have an opening at the front that allows cool air to pass through. It describes how cost and risk would be impacted by either construction concept, as well as performance and what developmental pitfalls could potentially impact either choice. Category Archives: Stealth Blackhawk & Bin Laden Raid.

They don't call them the Night Stalkers for nothing!There have also been claims that the stealth Black Hawk was in its second generation when the Bin Laden raid took place, with the older generation being used for the raid out of fear that losing one would compromise far too many technological secrets.

We know things are being played with all the time, but it is impressive to see it put into action. The US forces who raided the safehouse of Osama Bin Laden appear to have caught him ... 'Stealth helicopters' used in Bin Laden raid. Decreases of 7 and 11 knots in maximum cruise speed, 805 and 520 feet in hover ceiling, 248 and 740 feet in OEI service ceiling, and 0.14 and 0.19 hour in endurance were calculated for the LRCS2 aid LRCS3 configurations respectively.Clearly, the more elaborate the stealthy modifications to the baseline H-60 design, the more penalty was paid in drag, overall performance, and especially general instability.
