Very good news!
Now you just have to find the personnel to man the fleet properly.
1.5 crews per airframe perhaps? Plus sim staff, OCU staff, Staneval, etc. Probably 200 aircrew. Seedcorn will give you about 30-40. We also don't have a WSO training system any more (do we?), assuming the P-8 actually needs WSOs (which personally I don't think it does). Then there's the groundcrew, ops support staff, etc.
I haven't seen any news of retirements of other aircraft, couple this with a run on of Tornado, extra Typhoon Sqns etc. Presumably there are manning issues here?
