That's good enough for me
skytrain, as far as I can tell, it was known as the Lockheed Atlas (I can't find any other designation), and I was hoping that the various takeovers in the US Satellite Launcher field might confuse the searches.
The Lockheed Entry had Low IR and Visual Signatures, Gun: 25mm GAU-12/U Gatling, Redundant Controls, Tough, Prototype Flown in 1989; Privately Financed
GE Unducted Fan Engine and GAU-13 (4 barrel 30mm or 25mm) Gun Rate of Turn>25 deg/sec; Low SFC (long loiter), Low IR Signature, Low Vulnerability.
I notice that no mention is made of the row made by the "whirling Bananas", the enemy would have heard it coming for miles !!
Well done mate, you have Control
