I think it does. I think it is the logical replacement for the SR-71. The Blackbird, for all it's cool stuff is basically 1960's technology. The SR-71 would not have been discarded by the USAF/CIA unless they had another manned, quick response, strategic recce system in operation to replace it. Recce satellites are very good but they are (1) predictable and (2) somewhat restricted in their flight paths and (3) few in number and slow to respond to emergent tasking.
There are known incidences of certain civilian and military sensors tracking an unidentified flying object over the Pacific Ocean and SoCal at speeds of over Mach Six...or nearly 4500mph. The SR-71 won't match that.
The unique exhaust trails have been sighted. I think now that the planes always try to fly at night to mask this tattletale.
Imagine this for a mission profile:
2230 takeoff from isolated field in Nevada. Climb out to 35,000 to meet tanker. Top off fuel. Climb to operational altitude of over 100,000ft and accelerate to operational speed of M7+ TAS. Decelerate and descend for tanking vic Wake Is. Arrive at target in about two hours from launch, make two passes over target using all EO/IR/RF sensors, linking data to ground station via satellite comlinks. Make WIDE turn to begin return flight. Over southwest pacific again, slow to standard air-breather speed and descend to meet tanker. Tank again vic Guam...accelerate and climb to operational speed for final run home. Arrive at home base approximately 6-8 hours after departing, and before sunup. Target for this flight...Sydney, Australia, approx. 7500 miles from LaLa Land and about 8000 from base. Target could just as easily be Kandahar, Bagdad, Kosovo...or Beijing. Neat huh?
The engine propulsion technology has been around for a number of years. It was first postulated many years ago for the NASA space plane...but the basic designs and the raw technology suddenly was declared TS (codeword) by the government and disappeared into the Black.
The annual DoD/Intel budget listed in the Congressional Record accidently included a weird notation some years ago for a lot of IR&D funds for a strange project that had no obvious sponsors...yet the project got all of its money. The listing mistake was never repeated. (Pity that poor bureaucrat who made that boo-boo!)
BTW, I think the new spook base is at Tonopah, Nevada...although Area 51 remains in limited operation. It may take years to clean it up, since they have been using highly toxic exotic materials for years.
(Shhhhh...they're listening!) [8D]
