OBJECTIVE: AFSOC Mission Area Plans identify signature deficiencies for current transport aircraft. Next generation transports will require reduced observables across the threat spectrum to satisfy SOF mission requirements. However, there is no precedence for installation of efficient large fan propulsion units into advanced low observable air vehicles. Due to recent fighter/attack aircraft development efforts, technology readiness for some air induction components is considered medium to high, and promising technologies for exhaust nozzle components are beginning to evolve. This effort will determine propulsion sensitivities by integrating air induction components, fan propulsion units, and exhaust nozzle components into conceptual low observable transport configurations. High payoff technologies will be identified for inclusion in follow-on full scale development. Operability problems with fan propulsion units installed in low observable configurations will also be identified. Key factors considered are balanced low observables (IR, RF, acoustic), and propulsion system integration with powered high lift devices for STOL. SOF infil/exfil is expected to have the most demanding requirements, but technology derived from this effort will also be applicable to other medium size transport missions (tankers, gunships, airborne command and control, anti-submarine warfare, reconnaissance, etc.) This effort is coordinated with current air vehicle configuration development and advanced transport structures development.
TECHNICAL APPROACH: Trade studies of candidate propulsion components will be conducted via comparison of estimated system performance with these components integrated into a low observable airframe. Performance estimates will be obtained from empirical databases or advanced computational analyses. Promising candidates will be identified by air vehicle performance metrics including cruise range, STOL capability, detectability. Performance estimates and fan unit operability will be verified experimentally by standard subscale aero-propulsion wind tunnel test methods. Signature levels will also be verified by standard subscale RF range tests, IR measurements in conjunction with the wind tunnel tests, and exhaust nozzle acoustic chambers. Trade studies will be completed within the first year (Jun 97). Experimental databases for follow-on design and development will be available during the third year (Sep 98).
I do not think I can discuss senior citizen in any way.

Is there supposed to be some connection between this and the CREST requirements, or does that link point to the wrong doc?

The link is to the correct document.

As an afterthought about the possible connection between SOFTA and Senior Citizen (which has often been hinted/suggested/assumed but never clearly evidenced), here's an excerpt from a message sent by Burt Rutan himself:
I do not think I can discuss senior citizen in any way.
Note that he didn't say: "I don't know what the hell you're talking about"... To me, his reply indicates at least that:
1°) Burt knows full well about Senior Citizen.
2°) If he knows about it, chances are Scaled Composites must have been involved in it.
3°) If Burt didn't feel free to discuss it a couple of years ago then Senior Citizen must have been technologically-sensitive enough a program that it still fell under the veil of secrecy 20 years after the program's entry disappeared from budget lists.
From which we may infer that IF there was an article built at the time, however experimental, it featured technology that is still relevant to current operational articles. Thoughts anyone?
SENIOR CITIZEN was PE code 0401316F, a tactical airlift operational support program. In FY93 this PE code disappeared from the budget.
There has never been any *concrete* link between this program and special operations or R&D. At the time that SENIOR CITIZEN was active there were other, unclassified efforts to develop V/STOL airlift and the connection was inferred by several people.
In 1993 and 1994 test activity that *could* have been V/STOL aircraft were observed in and around the Nevada test ranges. It's now known that in the late 80s/early 90s Lockheed was contracted by DARPA to research new low observable V/STOL approaches for small strike fighters (GHOST HAWK). It is also now known that several contractors were working on V/STOL concepts for special operations applications as part of a series of DoD efforts. It is important to keep in mind that special operations were a much lower national priority at the time than today. It would have been very difficult to fund new fixed wing aircraft development for special operations needs.
The links between the SENIOR CITIZEN program and low observable V/STOL SOF concepts are very tenuous.
0401129F was THEME CASTLE, an airlift operations program. Other airlift operations programs of that period were things like funding for operational C-5 squadrons. THEME CASTLE was active during the same period that SENIOR CITIZEN was, but there has never been any other connection between the two.
Pretty amazing work- Did you works off plans or were there any photographs?I worked at Hughes GSG from 79 to 92 as a prototype model maker and had a secret clearance. I was contracted by Westco Models to make this aircraft for a trade show.

Normally not one to do Tyler Rogoway's job for him, but you should get in contact with him or Joe over at The War Zone. I bet they'd love to do a story about any of the model work you can talk about.I worked at Hughes GSG from 79 to 92 as a prototype model maker and had a secret clearance.
