A Joint Urgent Operational Need (JUON) identifies and subsequently gains Joint Staff validation and resourcing of a solution desired within days or weeks, to meet a specific high-priority need. It’s identified by a combatant commander and the scope is limited to addressing urgent operational needs that:
- Fall outside of the established Service processes and
- Will seriously endangered personnel or pose a major threat to ongoing operations.
The JUON doesn’t involve the development of a new technology or capability; however, the acceleration of an Advanced Concept Technology Demonstration (ACTD) or minor modification of an existing system to adapt to a new or similar mission is within the scope of the JUON validation and resourcing process.
Joint Urgent Operational Need are posted on the SIPRNET.
Urgent Operational Need (UON)
Capability requirements identified by a DoD Component as impacting an ongoing or anticipated contingency operation. If left unfulfilled, UONs result in capability gaps potentially resulting in loss of life or critical mission failure. DoD Components, in their own terminology, may use a different name for a UON.
Joint Emergent Operational Need (JEON)
UONs that are identified by a Combatant Command as inherently joint and impacting an anticipated or pending contingency operation.
Immediate Warfighter Need (IWN)
A subset of Joint Urgent Operational Needs (JUONs), so designated as IWNs by the Joint Rapid Acquisition Cell (JRAC), and has a materiel or logistics solution that must be resolved within 120 days or less.
