MDC designs concepts sized for air-to-surface missions. 1977 ATS (Air-To-Surface) studies prior to ATF program.

Some definite points of similarity with those designs and the eventual ATF submission.

A friend (Hi vstol) sent me this artist's impression a few years ago, titled "CTOL Light Attack Aircraft" with Navy insignia and tailhook. Nothing else is known.

Any idea, what could it be?

May I play CSI?? ;D
The airplane has a laser designator in the nose (it is illuminating the interior of what seems a hangar or a shelter and the two bombs (seem dispensers) are homing on the reflection). So this indicates a post 1970 date (laser designator were deployed on pods during the '60s). Sice there are no tropical/jungle hints, it must be post-1975. The airplanes are attaching an airfiled with what seem dirt-covered shelters, The scene has a north-african/Middle east look (what's the building near the upper end of the picture? Seems a mosque with a dome but it is out of contest, could be a radar station with a dielectric dome covering the antenna). Aircraft appareances are distincly post-F-117 era. So I'd bet the project is from the middle of the '80s, when Libya was THE villain. Was there some CTOL light-attack program going on in the US in the middle of the '80s? Perhaps a replacement for A-7s?

I've searched my files, but can't find anything. I've searched my brain, but it's empty too.

Upon closer study, I think it is just a notional airplane that was drawn to advertise the weapons. What is most striking (pardon the pun) to me is the laser designator in the nose, with the two glide bombs that seem to be tracking into the hangar. The near aircraft is banking to show the canisters on the bottom of the fuselage. One is missing, which maybe corresponds to an explosion on the bottom left.

Sorry, that's the best I can do. It is definitely not the MDA Quiet Attack Aircraft.

Mike,

A few mysteries come to stay, otherwise it would be boring ;).

Stop the presses! Mystery solved! I found it (without the tailhook):

It was a 1977 McDonnell design as part of their Air-to-Surface (ATS) study, which was one of the studies that eventually led to the start of the Advanced Tactical Fighter (ATF) program.

It was designated Model No. 252-111B with wing tip Air-to-Air missiles and conformal Air-to-Ground weapons underneath.

They must have pitched a version of it to the Navy, too, since McDonnell was a well-established designer of Navy aircraft.

Cheers,
Mike.

A 1971 USAF project, probably strike oriented, via Mark Nankivil.

Although it was a very high performance vehicle, the Model 252-2BF-3, a typical SX configuration fixed-wing attack aircraft, proved to suffer in the ratings due to lack of firm design and payoff information, Figure 2. Also, the then relatively undefined high-speed performance indicated a wing temperature condition that would require a thermal/structural analysis and materials other than the well characterized epoxy matrix composites

Appears to be a highly supersonic (hypersonic?) attack aircraft design.

This tail and canards design seems to be an ATS related study - ATAMS (Advanced Tactical Attack Manned Systems). Weight was 41,000 lb and payload = 4000 lb.

The McDonnell-Douglas ATAMS weapon system concept shown in Figure 7 resulted from a comprehensive air-to-surface technology and integration study. Study results included a mission definition and a vehicle concept that is affordable, able to penetrate enemy defenses, survive, and destroy important targets in large numbers in both fair and adverse weather conditions. The design mission of the ATAMS is a low altitude interdiction mission for a NATO/Warsaw Pact conflict in central and northern Europe. The ATAMS is powered by two augmented turbofan engines.

Source: AIAA Paper 1981-1503 Progress Toward a Long-Range Propulsion Plan, C.F. Baerst, R.C. Gunness,and S.W. Mitnik, Garrett Turbine Engine Co

The Advanced Tactical Attack Manned System is a tactical fighter having both air-to-air and air-to-ground roles. Mission is the air-to-ground strike mission (Figure 15) in which the aircraft cruises
subsonically to the forward edge of the battle area (FEBA) and dashes at Mach 1.7 to the weapons release point. Since STOL is not a requirement for the ATAMS. the aircraft is somewhat imaller than those being considered for ATF/STOL missions.

Greetings All -

Like the Lockheed Model numbers, the designs at times are all over the place. Here's a few variants that are titled under the 252 series. The RCS Mach 1.8 Penetrator is intriguing...

Enjoy the Day! Mark

Mark - that stealthy concept is very interesting. Some of the other designs look familiar from 70's ATS studies, will try to unite any other information here.

The canard design (Model 252-109A) seems to be the same design featured in the "ATAMS" concept and nearly identical to this artwork.

Model 252-111B seems a lot like this, previously identified as Model 269-F2 ATS study:

Model 269-F2

I believe Model 252 represents Phase 1 of McDonnell-Douglas ATS work and Model 269 Phase 2. Clearly Phase 2 reused and refined configurations from Phase 1.

Model 252 designation was assigned in 1970 with this entry in the McDonnell Project List:

USAF Advanced Tactical Strike Aircraft (SX) (13/02/1970 D. Redden)

Model 269 designation was assigned in 1975

USAF Tactical Fighter "Battlefield superiority fighter tailored to ground attack and reconnaissance roles with alternate capability as air superiority - deep strike - strategic" (13/10/1975 P. Czysz)

Thanks for sharing, now I have at least two more designs for the book I'm putting together.

(A belated) nice find Mark!!

It has a somewhat fixed-wing TFX/F-111 look to it
