Just for some perspective, here's the specs on the 80 year old piston engine Mosquito from WW-II:
Max Speed: 668 km/h (comp. 700km/h)
Range: 2100 km (comp. 700km)
Bomb Load: 1800kg (comp. 50kg)
True, the range goes down significantly with a full bomb load, but the numbers are so dominating that a pretty healthy adjustment could be made.
I'll go with the Oreshnik, thank you very much.
