...served as guidelines for R&D investments in the 1965-1975 period. Project Forecast was a technology push and as such necessarily impacted positively projects such as ISINGLASS. Especially after the demise of Aerospaceplane. More on project Forecast here: http://history.nasa.gov/HHR-32/ch12.htm

I suspect that ISINGLASS' demise had more to do with the retirement of General Bernard Schriever. Technical challenges may also have hurt it, but Schriever was apparently the program's patron on the USAF side.

So...it's been a year since we got our first decent look at ISINGLASS. I'm guessing that's all we're getting for now. However, has anything at all similar been released on RHEINBERRY?

Sorry for the delay in posting this document. This is the first 10 pages of the 52 page document entitled Summary Review of ISINGLASS Program. I will post the other pages shortly.

Don't know if anybody has seen this before but the CIA just put up some ISINGLASS docs in the last two weeks.

What is the vehicle on the first page? Just an example of hypersonic strike? It looks like it would be more at home on the Isinglass thread than in this kind of article.

That was my thought, but the odd "boat hull" fuselage in the front is certainly different (as is the planform). I'm left to wonder if this might be an ISINGLASS design or some such.

The rest of the document describes the ISINGLASS program. I'll post more later on this, however it looks as if S-103 and S-104 were studies used to compare manned versus unmanned systems.

An NRO memo to DRNO from Brig. Gen. Jack Ledford, USAF, as of 1965, indicates that the proposed propulsion system for ISINGLASS is the "RL-20 A-1." He also wrote that "P&W has also indicated a growth potential for this engine of about 10 seconds in Isp beyond the values attainable at the time of...

...it's like old "telephone" game where a message starts out one way and gets completely changed by the end of the game. So this mixup of ISINGLASS's maker has become very widespread. In fact, I was just going back through Bill Rose's still outstanding SECRET PROJECTS book on military space...

Noted at the time. From the Isinglass FOIA file on NRO.gov:

For what it's worth: R. LYNCH, GENERAL DYNAMICS CORP., GENERAL DYNAMICS/CONVAIR, SAN DIEGO, CALIF. "The first manned lifting entry vehicle configuration", 3rd Annual Meeting, Annual Meeting, 29 November 1966 - 02 December 1966 http://dx.doi.org/10.2514/6.1966-959...

It would be interesting to know if ISINGLASS has GRM-29's water cooling.

Any thoughts on McDonnell Douglas's GRM-29A?

Moonbat, remember Paul was talking about MOL not ISINGLASS. C-5 didn't first fly until the late 1960's, from what I recall.

Reading again the CIA and NRO sparse documents on ISINGLASS and RHEINBERRY. I've just realized something. Dyna-Soar was Boeing, sure. BUT - ASSET was a miniature Dyna-Soar nose, which contractor was... McDonnell. https://en.wikipedia.org/wiki/ASSET_(spacecraft) Program started in 1960 and first...

...The planform and basic configuration is similar to the GRM-29A (according to the ANSER document). This ties the planform back to the ISINGLASS development time frame. The ISINGLASS vehicle proposal was delivered in 1965 by McAir. My thought is that this is the Model 192 or a close variant of...

So pretty much Aurora's predecessor? Also pretty cool find from the people here, each day I learn something new here.

...SUCCESSOR of the A-12 to try and slain it - and get some kind of revenge against Lockheed ? Note that the (technical) distinction between ISINGLASS and RHEINBERRY was ISINGLASS: Mach 4.5, airbreathing > ramjets - HYPERSONIC RHEINBERRY: XLR-129 with 450 seconds isp and 0.80 mass fraction...

I was a big fan of this article Dwayne, might you be considering an update now that the Isinglass configuration is known??
