Delays with the J79-GE-8 engines meant that the first production aircraft were fitted with J79-GE-2 and −2A engines, each having 16,100 lbf (71.8 kN) of afterburning thrust. Source: Internet
Coolant injection (pre-compressor cooling) has been used, together with afterburning, to increase thrust at supersonic speeds. Source: Internet
