UK to purchase at least 74 F-35 jets
27-04-2022
It was revealed yesterday that the MoD is in negotiations with the F-35 Joint Project Office to buy another tranche of F-35 jets.
This second batch will consist of 26 aircraft, in addition to the 48 already under contract.
Was a rather short flight as during the STOVL transition one of the STOVL doors below the fuselage would not close. Somehow the pilot was able to close the hatch and it landed safely after about 15 min or so.
