The Department faces significant challenges replenishing its stocks and delivering new capabilities to meet the threats of a more volatile world. The Department has begun replacing stocks gifted to Ukraine, either on a like-for-like basis or with an equivalent where gifted capabilities are no longer in production or the Department now has different requirements.57 However, we are concerned that replacement is not occurring quickly enough, with, for example, the Department confirming that it will take at least two years to replace NLAW anti-tank weapons gifted to Ukraine.58
