Tranche 1: 37 single seat (36 operational, 1 as test aircraft), 18 two-seat (16 operational, 1 fatigue test, 1 as test aircraft).
Tranche 2: 83 single seat, 6 two-seat.
Looks like the two-stickers will be like rocking horse ****, only 22 operational airframes, probably only 1 per squadron after the OCU take their cut.
Tranche 3 is/was supposed to have 13 two-stickers (75/13). Looks like the balance of tranche 2 will have to be changed if this goes through.
