Few questions if you don't mind checking and/or answering: 1. Rate of Climb should be depended on payload. So that >320m/s RoC, is it when no payload is included and w/ max fuel? 2. Why 800 KM at ground level? Couldn't it be longer than that? 3. A gun w/ only 110 rounds? It must be insanely accurate and/or extremely long range-self guided shells?!!!
1. The rate of climb always means max rate of climb) So it is with minimum fuel and w/out of payload) Mig-29 now has the rate of 330 m/s and it is maximum for a combat aircraft. So i decided that it will be ok for a single engine fighter
2. fuel consumption on the ground level always is very high. This is one of the reasons airliners fly that high
3. It will be ok for a highly accurate future gun. 4-5 shells are enought for GSh-30 to destroy a fighter plane
