As far as I know are there still two SR-71 two seaters in the service of the NASA for high speed research mission and material testing. No SR-71 is by my knowledge in use by the regular forces.

according to the air force website the last sr71 was retired just a few years after being brought back in 1997. and according to the nasa website their last flight was 10/9/99. the nasa aircraft were given to museums in 2002.

S-71 isn't practical enoph in todays warfare. Because Russia and China got Mi-31's and all other anti american counties got mig-25's. Mig-25's isn't fast enough but they still got long range aams. It's will be easier for russians and chinese, they got mig-31's with zaslon and more powerfull long range aams.

I don't think it will be still in servise

there a great aircraft but high maitnence and fuel cost and they leak fuel all the time (when not flying) but no way they be in serviers unless some little terriost act got there hands on one then thats another question

people please stop being stupid--thanks

question 1--how would some little terrorist get their hands on one?
question 2--where would they fly it out of?
question 3--how would they maintain it?
question 4--where would they get the fuel?
question 5--would they also steal a kc135 so they could refuel it in midair as required due to the leaking fuel on the ground (an issue due to the heating of the skin)

answer 1--it would be next to impossible. they wouldn't want one as it can't drop bombs. oh and i am sure though that they have some sort of pilot training program under way.
answer 2--it needs an very long runway and i don't think there are any just out in the middle of nowhere that aren't being used that could accomadate this unusual aircraft.
answer 3--parts are hard to come by as it is so they had better steal 2 so one can be kept in flying condition.
answer 4--the fuel isn't made anymore as it was a special blend just for the sr71. the flashpoint for it was so high that it was piped through the leading edges of the plane to help absorb some of the heat generated by friction. (you could drop a lit cigarette into a barrel of the stuff and the cigarette would go out)
answer 5--this will probably be easier to do that to steal the sr71 but still exceptionally hard.

ANSWER for this subject :No
Too expansive
Not practical in 21 centuary.

question do u have a sence of humor


answer NO!!!!

the terriosts could hide some of the things down the pants the fuel just pop down to the servo and pic up some high octane fuel *oh and u can drop a match in to a can of unleaded fuel and the match will go out* um who said anthing about a runway just use the desert it will do, bombs arnt an issue come one U GET INA PLANE U RAM IT INTO BUILDING, people u need to start and wake up to life and what really happens in this world, ok i said if some terriosts would get there hands on one i think it was a joke hang on ill check............ yes it was a joke like HA HA HA

You are funny guy
