That I cannot say. What I can say is that the US and France plus other countries are looking at the Brimstone Missile with a view to purchase. In one instance the missile took out a sniper in a wall around a building and only knocked down 20ft of the wall. The building and the rest of the wall was untouched. Its basically a major development of the Helfire Missile.
Its precision, small warhead, light weight (approx 110lb) and relative low cost makes it a very effective weapon.
Its also a good example of why the UK were adamant about getting access to the core code for the F35. Without it we would not be able to integrate UK missiles into the F35.
