I-320, FN by A.I.Mikoyan/M.I.Gurevich

Predecessor of the MiG-15. Single engined straight wing aircraft of the MiG-9 line.

Straight wing was forced in by opinion of conservative designers and (short-living) success of the Yak-23. Swept wing was viewed with a suspicion by 'the neighborhood'. Several failures of German designs provided even more doubt. The FN was designed and built during 1946- 1948, but abandoned because since March 1947 bureau started more promising I-310 (S) with same Nene-1 engine.

The first Soviet swept-wing jet fighter (La-160) was flown in Summer 1947, a nd there were no more objective reasons to proceed with conservative straight wing design.

Designation I-320 was reused later for the 'R' project.
