The Su-75 Checkmate Proves 1 Thing: There is no such thing as a ‘cheap’ stealth fighter. The Russian attempt to create a low-cost, single-engine, fifth-generation stealth fighter for the export market has so far produced little of substance. When developing the aircraft, Sukhoi emphasized its intention was to build a fifth-generation stealth aircraft at a significantly lower cost. The main selling point in Dubai is that the per-hour cost of flying the Su-75 would be seven times cheaper than the U.S. F-35 stealth fighter. “Work is in progress on the design documentation for the light fighter,” Rostec stated at that time.
