IHI started development work on the high bypass ratio turbofan engine in 1998, based on the low bypass ratio engine XF5-1.

PFRT was based on the Military Specification MIL-E-5007D and the original standard about the FADEC system.

[2] Take off thrust is 60 kN (13,000 lbf), bypass ratio is 8.2, and SFC is 0.34 kg/h/daN.

[4] Strong alloy materials were selected for high corrosion resistance in salt environments, and a sound absorbing panel is mounted.

[6] P-1's F7-10 is installed thrust reversal with GE's cowl opening systems.
