APPARATUS FOR UNMANNED VEHICLES
Apparatus and a method performed by the apparatus, the apparatus being wholly or partially mounted on an unmanned vehicle (e.g. an unmanned air vehicle) and arranged to act upon a payload (e.g. a lethal effector), the payload being mounted on the unmanned vehicle and, under an action of the apparatus, able to be changed from being in a first state to being in a second state, the method comprising: receiving an instruction that the unmanned vehicle, with the payload mounted thereon, is to travel to a location; determining that the payload is in the first state; and responsive to the step of determining that the payload is in the first state: opposing the payload being changed to being in the second state; and providing, for an entity remote from the unmanned vehicle, an indication that the payload is in the first state.
