NASP final congiguration/iteration drawings

Scott, I have seen that stuff with boat tale and pronounced aerospike block between twin tails (and wings are delta vs. double delta at X-30 final pics) - there are some papers online and one wind tunnel photo on Langley site, but I always thought that it was post-X-30 design for NASA's advanced TSTO first stage - at least all the sources have images of common-shape vehicle. |

At worst - well, what bad things could happen from releasing NASP technology? Such a release might acutely embarass certain NASP advocates by making it clear that they had no grasp of the magnitude of the technological leap required to make something like NASP work. Jim Davis |

Some guys (say Sweetman) suppose that NASP was a cover program for something
that became operational: "The fact that cover is extensively used to protect black programs adds weight to the theory that some white-world projects may, in fact, be intended as cover. One example is the X-30 National Aerospaceplane (NASP) project, which was launched in 1986, cut back in 1992 and terminated in 1994. In retrospect, the stated goal of NASP - to develop a single-stage-to-orbit vehicle based on air-breathing scramjet technology - seems ambitious and unrealistic. Considered as a cover for a black-world hypersonic program, however, NASP was ideal. NASP provided a credible reason for developing new technologies - such as high-temperature materials and slush hydrogen - building and improving large test facilities, and even setting up production facilities for some materials. These activities would have been hard to conceal directly, and would have pointed directly to a classified hypersonic program without a cover story. " Ok, I'm not another Aurora believer...but Boeing Bird of Prey unveiling makes me think that someone still have good habit of keeping secrets tight. I'm not sure for North Korea bombers, but AFAIK Russian hypersonic strike platform program is pretty on the way...rather it's pretty well classified...or RIP because of lack of funds. It just remembers me situation when papers regarding military use of atomic energy dissapeared before WWII - as well, all public mentioning of all that crazy AYAKS and NEVA concepts are dissapeared...and every MAKS airshow I see IGLA/GLL/GELA hypersonic testbeds that means that something moves...somewhere. At least Rosaviacosmos heads stated several times that hypersonic plane studies are underway. Regards, Gregory "Allen Thomson" ???????/???????? ? ???????? ?????????: m...

I'm not sure that the real configuration was ever declassified. If (dim) memory serves, that flat-nosed configuration was supposed to be generally representative of current thinking, nothing more -- something to show in publicity material. Which does raise the question of why technology developed in a somewhat long-ago failed program should still be classified. If released, at best, it might help current CATS efforts (though I doubt it). At worst - well, what bad things could happen from releasing NASP technology? North Korean hypersonic bombers swooping on Los Angeles? |

Such people are relatively few, and the effort takes time and money. That's a nice theory, but it isn't the way that most of the millions of pages that get declassified each year get declassified. Substantitive experts are rarely used for declassification -- at most, they may help write guidelines for fairly low-level declassification clerks. In addition, bulk declassification is certainly possible if a decision is made that a general topic is no longer sensitive. |
