mmmhmmm seems like a fanboy idea to mean, why bring a retired bird design from the 1970s back to the modern era when you can prolly have a F22 with an observation pod doing the same job.
Mach 3.3 and a service ceiling of 26 km does not mean much to a mordern SAMs which can engage up to Mach 8 targets.
Actually, altitude and speed does matter; at such altitudes and speeds that the SR-71 operates at, SAM's have very little energy to maneuver to make an intercept. Very few SAM's have the performance necessary to even attempt an intercept, and even then, it is a crapshoot. Many SAM's don't even have the ability to intercept targets above
according to a japanese newspaper, US is considering bring back SR-71 to pacific as a insurance,uncase US IMINT satelite were destroy or damage by Chinese ASAT.
In 1968, Secretary of Defense Robert McNamara canceled the F-12 interceptor program; the specialized tooling used to manufacture both the YF-12 and the SR-71 was also ordered destroyed. Production of the SR-71 totaled 32 aircraft with 29 SR-71As, 2 SR-71Bs, and the single SR-71C.
Final retirement
The reactivation met much resistance: the Air Force had not budgeted for the aircraft, and UAV developers worried that their programs would suffer if money was shifted to support the SR-71s. Also, with the allocation requiring yearly reaffirmation by Congress, long-term planning for the SR-71 was difficult. In 1996, the Air Force claimed that specific funding had not been authorized, and moved to ground the program. Congress reauthorized the funds, but, in October 1997, President Bill Clinton attempted to use the line-item veto to cancel the $39 million allocated for the SR-71. In June 1998, the Supreme Court of the United States ruled that the line-item veto was unconstitutional. All this left the SR-71's status uncertain until September 1998, when the Air Force called for the funds to be redistributed. The plane was permanently retired in 1998. The Air Force quickly disposed of their SR-71s, leaving NASA with the two last airworthy Blackbirds until 1999. All other Blackbirds have been moved to museums except for the two SR-71s and a few D-21 drones retained by the NASA Dryden Flight Research Center.

The 24th, in mind China to advance not bring it close to their waters the U.S. military the "access denial strategy", a new reconnaissance aircraft that can break through the defenses of the enemy and we need Kohler commander of the U.S. Strategic Command is (Air Chief Marshal) I made it clear idea of. I said in an interview with some media, such as Kyodo news agency.
I declined to mention the concrete specifications of reconnaissance aircraft. U.S. magazine Foreign Policy (electronic version), you are like a supersonic reconnaissance aircraft SR71 that was used in reconnaissance against the Soviet Union during the Cold War, it's remarks with a view to the revival of stealth reconnaissance aircraft capable of long-distance flight . Mr. Kohler stressed that "need to counter the approach denial strategy" he said. It said, "potential threat in space is increasing," and based on the (ASAT) development satellite weapons by the Chinese, it was acknowledged that to prepare for things that will not be able to communicate and reconnaissance by the U.S. military satellite is the essential further .
