Yes they do....the United States...
"On 13 October 1973, Pilot Jim Shelton and RSO Gary Coleman in #979, departed Griffiss AFB on the first of a series of flights to the Middle East. After 11.13 hours of flight time involving 6 refuelings and more than five hours of flight above Mach 3.0, Jim Shelton landed SR #979 back at Griffiss AFB, NY. The "Photo Take" was highly successful and provided Defense Analysts and the President of the United States with information about the actual Syrian military situation. On 25 October 1973, Pilot Al Joersz and RSO John Fuller flew SR #979 on another 11.13 hour non-stop round robin sortie to assess the ground situation around the Sinai and Galilee. On 02 November 1973, Pilot Bob Helt and RSO Larry Elliott in SR #979,flew a similar Trans-Atlantic sortie to the Yom Kippur War zone in 11.22 hours of flight. The last flight from Griffiss AFB was 11 November 1973. Blackbird #964 was flown by Pilot Jim Wilson and RSO Bruce Douglass and landed at Seymour Johnson AFB, North Carolina. This sortie lasted 10.49 hours. As snow fell in Rome New York, Colonel Pat Halloran opted for a warmer climate and moved operations to Seymour Johnson AFB, NC. These SR-71 Reconnaissance flights were instrumental in defusing the war and provided positive intelligence photos to the deeply distrusting Israelis and Arabs."
"Though the Americans provided the Israeli military with weaponry, they also provided Israel with something far more important – intelligence. Documents relating to the American spy-plane, the ‘SR-71 Blackbird’, show that the Israelis knew where major concentrations of Arab forces were as they were supplied with this information as a result of a SR-71 flying over the war zone. With such knowledge, the Israelis knew where to deploy their forces for maximum effect. What appeared to be intuitive devastating counter-attacks by the Israelis, were based on very detailed information gained from American intelligence. Basically, the Israelis knew where their enemy was and could co-ordinate an attack accordingly."
