Woodford will cease to exist when the final MRA4 PA12 leaves production. If an order for a replacement is not done soon then there will be no MRA4/R1 replacement, not to say it will be another type though.
They cannot use the first 3 production a/c as PA03 has been dismantled and as far as im aware it looks like PA01 and PA02 will be disposed of at Kinloss although I cannot confirm 100% on that.
Tbh I think its too late in the game now to refit an MRA4, lack of funds the RAF were lucky to get 9 frames. 30 mins I believe the defense minister came to chopping the MRA4 earlier this year. Swift talking by seniors of 2 services saved the project..
