I read an unpublished interview of Bill Park (second pilot to fly the A-12) in which he didn't say the fastest or highest flights. He regarded the question as irrelevant. He said it was hard enough to get the aircraft to fly at the specified speed and altitude, do a 180° turn, and come back, so that Lockheed would have met the terms of the contract and could get paid.JimK said:FighterJock said:So what was faster in terms of overall speed? A-12 or SR-71A? I have heard many stories over the years that the SR-71A was faster than the A-12, could someone clear this up for me. :-\

I would interpret the equality of Mach numbers listed as a propulsion system limitation.
Thanks for that JimK, good information that has gone on to help me with my initial problem. B)
The aircraft went through a patch of exceptionally cold air, which is a boon to attaining higher speed. It accelerated to (based on what I was told) Mach 3.47 and perhaps an altitude of greater than 93,000 feet. (It may have been as much as 95 or 96K, but the person who was telling me this couldn't remember exactly.)
On that book,It seems to be called B-71,but I didn't find the same but clearer picture in this Web forumsI look it from a old book that is from the library.
From RAINBOW to GUSTO:……(The text was damaged)Hi Resister1976,
what was this book ?,and do you mean it was a bomber version ?.
thanks,and I find the second half of the pictureFrom Crowood's book,by Steve Pace.
At last,I wish you have a good healthFrom Crowood's book,by Steve Pace.
Or four SRAMs with 500 mile range.Not the worst idea I've ever heard, actually thought about it a few times myself. Payload is obviously going to be extremely limited, the A-12 would have carried three AIM-47 Falcons at around ~800lbs each in individual bays...that fits the size and weight of a B61 pretty well. So three dial-a-yield gravity bombs with settings up to 400Kt or so each, on a Mach 3+ airframe. Really feels like that should be useful for something, but I'm drawing a blank on what.
I think the concept of using the SR as a maritime strike platform with a KE weapon comes purely from a few paragraphs in Kelly's own autobiography rather than any on-paper proposal:But there was no conventional version of SRAM and its inertial guidance wasn't really suitable for conventional strike, especially against maritime targets.
Why... yes. Yes there are.Folks,
Are there any artists' impressions or three-views that show what an operational F-12B would have looked like? I'd love to built it in 1/72 one day.
Can someone mention the LASRE tests carried out by the SR-71?
Thanks my friend.Can someone mention the LASRE tests carried out by the SR-71?
There is a lot of information online. You might wish to start with the basics:
Linear Aerospike SR-71 Experiment (LASRE)
The NASA/Lockheed Martin Linear Aerospike SR-71 Experiment (LASRE) concluded its flight operations phase in November 1998.www.nasa.gov
Essentially, the Blackbird acted as a "flying wind tunnel" by carrying a dorsally mounted, subscale, half-span X-33 model. Plans called for aerodynamic studies, cold flow tests, and finally a hot-fire. Unfortunately, due to safety concerns, the hot fire never took place.
One of my fondest memories is of standing off to one side and slightly behind the SR-71 during engine start prior to a LASRE test mission in October 1997. Those V8 start carts were super loud, and the green flash of TEB was awesome. Good times.
Not very clear, best I have.I am a modeller and wish to find a clear photo of the rear part of the canoe where the exhaust pipes lie, as the shape there is not very clear.

I remember (vaguely) reading something somewhere a long time ago about Kelly Johnson saying that a penetrator shape made from hardened tool steel with a guidance nose could be used to take out missile silos. Again a long time ago but I recall him mentioning in the article how many feet of reinforced it concrete it would go through vaporizing much in its path and obviously destroying the missile without using a nuke to do so.Madoc said:Wow. Interesting to see what applications Kelly Johnson and crew would come up with for their CIA special. I recall one proposal for the A-12/SR-71 was to use the thing in an anti-ship capacity. The rounds for the task simply being big rods of titanium with some guidance equipment attached. The reasoning being that the kinetic energy imparted unto the target vessel by a few thousand pound projectile after it'd been fired/dropped by the Blackbird going at Mach 3+ would suffice to vaporize a goodly chunk of the enemy ship.
I can't see that working - titanium is very low density for a penetrator (tungsten would be much better) and it would lose velocity after launch, and mach 3 is not that fast by the standard of naval projectiles. It would be like getting hit by a dud 16" naval round at worst. Something like a Harpoon missile would be far more deadly.

He confirmed late that it was Photoshop- the contrails just didn't match the engine spacing imhoTwitter...
Photoshop is a hell of a drug.
