    Personal pics? KC-135Q, dont see much of those anymore

    Didn't read the Wiki, but this thing had to have its own fleet of tankers to support it. Couldn't use the regular KC-135/KC-10s that were out there already for its JP-7.


    About JP-7
    JP-7 is a mixture composed primarily of hydrocarbons, including alkanes, cycloalkanes, alkylbenzenes, indanes/tetralins, and naphthalenes, with addition of fluorocarbons to increase its lubricant properties, an oxidizing agent to make it burn better, and a cesium containing compound known as A-50, which aided in disguising the radar signature of the exhaust plume. The Blackbirds used approximately 36,000 - 44,000 pounds of fuel per hour of flight. It's estimated that over 20,000,000,000 (20 billion) pounds of fuel was burned during the life of the program...

    ...The very low volatility and relative unwillingness of JP-7 to be ignited required triethylborane (TEB) to be injected into the engine in order to initiate combustion and allow afterburner operation in flight.
    And a little about the tankers
    To accomplish this, specialized KC-135Q tankers were required to refuel the SR-71. The "Q-model" tanker had a modified "high-speed boom," which would allow refueling of the Blackbird at nearly the tanker's maximum airspeed, with minimum flutter. The Q-model also had a separate fuel system, which kept the tanker's fuel (either JP-4 or later JP-8) isolated from the JP-7 needed by the SR-71. During its operational life, the SR-71 had dedicated KC-135Qs and aircrews sitting on alert, ready to launch within minutes to tank up a Blackbird. Some of these alert birds were located on the east coast (Pease AFB, Loring AFB, Plattsburgh AFB etc.); on the west coast; at Hickham AFB, Hawaii; Mildenhall, England; and Guam.
    I wouldn't mind being a nav on one of those. Not a bad base for any of them

    I'm going with: right out of the muzzle, yes, however it would lose momentum almost too quickly to calculate.

    The SR-71 would smoke the Mig-25.

    I guarantee we have something that services the same roll... Look at the "stealth helicopter" no one even knew it existed, and if it hadn't gone down...

    Satellites are great, but they have to be moved into position. The current fleet of known drones are great if we have the assets in position (slow). If you need eyes on target quickly you need a fast bird like the sr-71. The blackbird really wasn't stealthy, I bet we have something faster and with modern stealth technology out there now.

    But the Blackbirds were always intended to be stealthy, incredibly fast reconnaissance aircraft. They were expensive to maintain and fly. So now that we have spy satellites that can read handwriting, or monitor the movement of house windows to determine what is being discussed inside, we don't have much need for manned reconnaissance aircraft.

    Those fuckers were amazing though... there are new stories coming out all the time.
    Common misconception. Satellites are easy to avoid, they can be timed, and usually they can only photograph one location 1 maybe 2 times a day for a short span. We still have a need for this aircraft, and Sen John Glenn said it's retirement was a travesty for our intelligence. In my opinion, I find this aircraft to be the most impressive ever designed, even more so than the space shuttle. I just hope the Aurora really does exist.

    Here's an excerpt from wikipedia:

    Much speculation exists regarding a replacement for the SR-71, most notably aircraft identified as the Aurora. This is due to limitations of spy satellites, which are governed by the laws of orbital mechanics. It may take 24 hours before a satellite is in proper orbit to photograph a particular target, far longer than a reconnaissance plane. Spy planes can provide the most current intelligence information and collect it when lighting conditions are optimum. The fly-over orbit of spy satellites may also be predicted and can allow the enemy to hide assets when they know the satellite is above, a drawback spy planes lack. These factors have led many to doubt that the US has abandoned the concept of spy planes to complement reconnaissance satellites.[73] Unmanned aerial vehicles (UAVs) are also used for much aerial reconnaissance in the 2000s. They have the advantage of being able to overfly hostile territory without putting human pilots at risk.
    The problem with the SR71 is they never wanted to retrofit the aircraft for live data transmission. The SR-71 still relied on film, which had to return to base, be extracted, developed, and distributed to commanders.

    that or if you need a quick pass somewhere and you dont have satellites in position.

    Didn't watch any of the vids yet, just something I remembered from way back.

    Likely it is replaced by something out of skunkworks, like the Aurora with its SCRAMJET engine. It hasnt ever been confirmed, but there are giant budget "holes" of money and unexplained sonic booms in testing grounds to give you an idea that something is up there.
    I'd bet green money most of that stuff is proof-of-concept work for DARPA and missle research. There's no point in a super-fast jet for recon work anymore.

    makes you wonder if they could build that in 1964 then whats out there now! lol...
    I love the part in one of the articles that said it originally used two Buick Wildcat engines to start it up.
