While Jets may not be top of the list of Priorities they should still be on the list. Our troops need to train with fast aircraft flying over head, they need to know the levels of noise etc that will become part of what they might getting into with the battlegroups. As for not having air thread, we might we don't know. Does the UK have a realistic air threat!!!! I don't think so, same with France , Germany, Sweden, Switzerland etc
We have trainers, that is all to secure the pilots interest and for future generations of recruits they need something to aim for. While they are low on the priority list, do not discount the need for them. But if I had Usd 100m, to spend they would be down the list and second hand that 100m would be taken with Helicopters of which we need more and transport of which we have none.
