According to this site:

This is the ETPS "fleet"
- Hawk T Mk 1 XX342
- Astra Hawk T Mk 1 - XX341
- BAC 1-11 ZE432
- Andover C Mk 1 - XS606
- Tucano T Mk 1 ZF510 & ZF511
- Bassett VSS XS743
- Gazelle HT Mk3 XZ936 & XZ939
- Sea King HC Mk4 ZB506 & HU Mk 5 XZ575
- Lynx AH Mk7 ZD560 and ZD559
So it looks like it will be the Hawk that's used for jet/swept wing spinning. Just to clarify the first post - the advantage the Hunter had was that it was cleared for
inverted spinning, and that was what the programme was alluding to; the Hawk is of course cleared for erect spins, and used to train these routinely.
