A PDF pieced together from scans found on the Secret Projects forum of Senate testimony on the AIM-95 Agile air-to-air missile. Agile was, as the name might suggest, a close-in “dogfighting” missile, an attempt to incorporate the hard lessons learned by the USAF and USN getting their tails kicked in the skies over Viet Nam by scrappy Russian dogfighters pilots by scrappy Vietnamese pilots. The main advantage that the Agile provided over the Sidewinder was that the infra-red seeker was capable of looking further off boresight… in other words, you didn’t need to point the plane at the enemy before the missile could get a lock-on. While the AIM-95 Agile apparently worked just fine, it was simply cheaper to upgrade the Sidewinder.

The AIM-95 would be steered via vectoring the nozzle rather than aerodynamic control fins. Initial targeting was planned to be done by having a sight integrated into the pilots helmet.. where he looked, the missile looked. The AIM-95 was intended for use by the F-14 and then the F-15 as well, but it never entered service.

The PDF file is HERE.


Much more aerospace stuff is available via the APR Patreon.

The National Air and Space Museum is, at last, working on restoring their Ho 229. The 229 was an interesting flying wing jet fighter built in Germany during WWII; it had great potential, but as with most such things its legend has been blown far out of proportion, with recent years seeing claims that it was designed as a radar-stealthy fighter (it almost certainly wasn’t) and that it was the source of the postwar Flying Saucer mythology (difficult to envision since none seem to have survived the war in flyable condition).

A website has been set up to document the restoration of the Ho 229. The plane needs a lot of work… construction was of welded steel tubing covered with plywood. The years have not been kind to the plywood.

I have made available for APR Patrons the following:

1) “Titan III B-C-D-E Propulsion Handbook,” from Aerojet, explaing and diagramming just about everything you want to know about the Titan III propulsion systems, from the SRMs to the Transstage. I originally got this via ebay.


(This shows just a small portion of the ~300 page handbook)

2) “Aircraft Descriptive Data for Northrop F-89F.” A collection of then-current data on the projected (and unbuilt) F-89F. This was from a collection gathered by Lockheed to keep tabs on their competitors. Has some “Secret” markings on it. I originally got this via ebay.


3) Skylab diagram. This very large format illustration was found in the NASA HQ and photographed piecemeal and painstakingly reassembled, using text scanned from another copy of the illustration (with a far smaller diagram, but good text).


4) An original layout diagram of the XB-70. It took several years to get this diagram into this shape. It seems pretty good to me.

misc-127 XB-70

You can gain access to these by becoming an APR Patron for as little as $1.50 a month. That’s not so very much, is it? Check out the APR Patreon page for more details.

I have been busy with a number of things recently (some good, some bad), which has clearly reduced my Aerospace History blogification substantially. So… here’s a cutaway of the XB-70:


Granted, it’s tiny. However, a far bigger version of this illustration, created Way Back When for “Flight” magazine, is available on the Flight archives, right HERE. From back when such bits of beauty were created by hand.
