The P- designation system starts with P530 as, legend states, the engineers were working "off the clock" after work, and couldn't register the design in the normal N- sequence, so labelled their drawings "P530" for the time they started work (5.30pm).

P530 N-300 Cobra
P600 N-321 Twin engine LWF/ACF submission (YF-17)
P610 N-322 Single engine LWF/ACF submission
P630 Navalised F-17 (Northrop-only design to VFAX)
P700 N-310 Advanced Tactical Fighter, F-X Program, (1968) also N347 N/D-102 (1980s)
P800 N-341 Advanced Fighter
P900 N353 Mission Adaptive Fighter
P1000 Generic Fighter Technology / N360 Baseline Advanced Fighter / N364 Advanced Supersonic Cruise Fighter

It appears to me that the P- series are private venture fighter designs, not to a specific contract but done "off the books", to explore various configurations. When there's an actual contract involved, an official N- number is usually assigned in addition. Some P- numbers spanned multiple N- numbers as the same designs got reused in different study contracts and evolved over the years.

This entry seems a little odd to me. Was the phrase "Advanced Tactical Fighter" already in use in 1968?
And why would a 1968 program be included within a 1982 program?
Otherwise cool summary of the P- series of designs, thanks.
