  • the UAV/payload is not permitted to be returned to a friendly location (e.g. the base). This tends to be the case even if the payload on the UAV has not been armed or activated.
  • the return of the payload is not permitted because the risk of the payload having a detrimental effect on the location it is returned to is deemed to be too high.

  • the UAV 2 is in effect, deliberately crashed in a relatively isolated region.
  • An advantage provided by the above described system and methods is if it is decided that the payload 6 is not to be delivered to the target 10, and hence the payload 6 is not armed, then it tends to be possible to return the UAV 2 to the ground base 8.
  • the UAV 2 and/or payload 6 may then be reused. This tends to preserve resources (e.g. UAVs, munitions, etc.) until they are needed, i.e. until it is desired that the payload 6 is delivered to a target 10. Moreover, costs tend to be reduced.
  • a further advantage is that a risk to the ground base 8 when returning the payload 6 to the ground base 8 tends to be advantageously reduced.
  • positive confirmation that the payload 6 has not been armed is provided from the UAV 2 to the ground base 8 throughout the UAV's return to the ground base 8. This positive confirmation is provided by the payload arming system 4 which iteratively checks that the payload 6 is unarmed. If no such positive confirmation can be provided by the UAV 2, then the UAV 2 is prevented from returning to the ground base 8.
  • a further advantage is that if it is decided that the payload 6 is not to be delivered to a target (or no target is identified for the payload 6), it tends to be possible to avoid having to deliver the payload 6 to a relatively remote location. This tends to be in contrast to conventional methods in which payloads are effectively abandoned in relatively remote locations instead of being returned. Thus, the risks of detrimentally effecting third parties (e.g. civilians) when abandoning a payload, tend to be reduced or eliminated. Moreover, the risks of unarmed payloads being retrieved by third parties (or an enemy) tend to be reduced or eliminated.
  • third parties e.g. civilians
  • a further advantage of the provided system and method is that the disadvantages of launching the UAV 2 with onboard payload 6 with no specific target identified (e.g. in anticipation of a target being identified) tend to be advantageously reduced.
  • a UAV 2 can be launched without a specific target being identified, and if no such target is identified, the UAV and unarmed payload can advantageously be returned.
  • This tends to be in contrast to the conventional approach in which if no target is identified, the payload is delivered to a relatively remote location.
  • This advantageously tends to reduce response time for a UAV, i.e. the time taken for a UAV to deliver a payload advantageously tends to be reduced because the UAV may already be airborne.
  • Apparatus including the payload arming system 4, for implementing the above arrangement, and performing the method steps described above, may be provided by configuring or adapting any suitable apparatus, for example one or more computers or other processing apparatus or processors, and/or providing additional modules.
  • the apparatus may comprise a computer, a network of computers, or one or more processors, for implementing instructions and using data, including instructions and data in the form of a computer program or plurality of computer programs stored in or on a machine readable storage medium such as computer memory, a computer disk, ROM, PROM etc. , or any combination of these or other storage media.
