An Urgent Operational Requirement (UOR) is a system used by the British Ministry of Defence (MOD) to obtain urgent equipment for operations. Supplementing the MOD's long term planned equipment programme are Urgent Operational Requirements (UOR), funded by extra Treasury money to provide the fast equipment solutions that ever-changing operations demand.
Urgent Operational Requirements (UORs) arise from the identification of previously unprovisioned and emerging capability gaps as a result of current or imminent operations or where deliveries under existing contracts for equipment or services require accelerating due to an increased urgency to bring the capability they provided into service. These capability shortfalls are addressed by the urgent procurement of either new or additional equipment, enhancing existing capability, within a time scale that cannot be met by the normal acquisition cycle.
