My take on this, a bit of devil's advocate
Joint Helicopter Command (or whatever it's title these days is) has two MOB for each of the services, plus Netheravon and Aldergrove as satellites, expect at least half of Benson / Odiham / Middle Wallop / Culdrose and Yeovilton to go.
A consolidation of JHC bases has been on the cards for some time, with proposals to move a lot of helicopters to Boscombe Down, its not clear if anything has come of this, but will probably feature in the review. Benson would certainly be an attract sell off in terms of land values in Oxfordshire, same with Odiham, but cannot see Yeovilton or Culdrose going. I'd argue Netheravon doesn't really figure in the plans, its pretty dilapidated infrastrcuture up there these days.
C130 fleet has been drastically reduced, wouldn't be surprised to see the remaining airframes retired.
I am struggling to see a complete retirement of the C-130J fleet, still heavily utilised by SF and given the issues with A400M, there is a shortage of tactical transport.
48 F35Bs might be the total order. Highly unlikely that the MOD will ever get anywhere near the projected 138.
Agreed, Tempest will have a part to play in this too, will be buying less from the US in the future given the volatile, emerging market standard pound that we now have since Brexit.
Leeming to close and 100 sqn's role to be privatised? All Hawks T1s removed from service, 736 NAS to stand down.
Leeming is more than just 100 Sqn and an airfield, lots of interesting RAF units based there, and its a strategically useful airfield.
Withdrawal of the remaining Tranche 1 Typhoons, therefore reversing the decision of the last SDR.
Can't see this, unless the UK opts for additional Tranche 3/4 jets, which is unlikely too. Too many demands on the fleet. But never say never.
Red Arrows to disband? Hugely unpopular decision, but the Hawk T1's OSD brought forward will force the issue.
Red Arrows, never until they have to replace the Hawk, a political black hole for any party that does it, and not much of a financial saving all in all.
