Northrop P-610 single-engine variant of the YF-17 Cobra (later F/A-18 Hornet)
At the time of the USAF’s ‘Light Weight Fighter’ (LWF) Request for Proposal, Northrop attempted to cover its bases, by submitting both a single-engine design, the P-610, and the twin-engine design, the P-600
Both the USAF and Northrop went with the P-600, which would be developed into the YF-17 Cobra, and later further developed into the larger and heavier F/A-18 Hornet for the US Navy.
But it is the P-610 that I am interested in
The P-610 design was very similar in layout to that of its two-engine P-600 design submission. But it was thought by some to not be as a refined as its twin-engine cousin. Although Lt. Gen Stewart would state that the P-610 looked as good or better than the twin-engine P-600 design. Northrop understood the single-engine F100 turbofan design would also make sense to the USAF, as it used this engine in its premier fighter, the McDonnell Douglas F-15 Eagle.
But the status of the P-610 designs completion would soon be sealed with the death of its designer, Northrop Engineer Bill Roth, and with his death the P-610 would never be finished.
Does anyone have pictures, drawings (including 3-view drawing) and technical data / specifications for the single-engine P-610?
