     All 'classic' F-28s are equipped with two Rolls Royce RB-183-2 Spey
Mk-555-15 engines (or various subtypes thereof). This engine is a two-shaft
turbofan engine with a by-pass ratio of 1.
     All Fokker 100s are equipped with two Rolls Royce RB-183-03 Tay
Mk-620-15 or Mk-650-15 engines. This engine is also a two-shaft turbofan,
combining the RB-183-2 core with a new LP system, raising the BPR to 3. The
Fokker 70 variant was only available with the lower-rated Tay Mk-620-15.
     No single-shaft turbojet engines have ever been fitted to an airframe
in the F-28 or F-100/70 series.
