It’s no secret the Russian air force has failed to achieve air superiority in the sky over Ukraine.Hamstrung by inflexible procedures, desperately short of precision weaponry and battered by stiff Ukrainian air defenses, the Russian Vozdushno-kosmicheskiye sily, or VKS, at best is holding its own over Ukraine, despite a 10-to-1 numerical advantage in fighters and attack jets compared with the Ukrainian air force.

But that doesn’t mean the Russians are doing everything wrong. The three regiments flying the VKS’s best interceptor—the twin-engine, two-seat Mikoyan MiG-31BM—are winning where most of the rest of the air force is losing.

Maybe there is some answer to this threat. What if "biolabs" could hatch few squadrons of F-15s?
