An UON as an Urgent Operational Need of one service. With respect to the Navy, the Defense Science Board states, "The solution strategy for a Navy UON may be a mix of interim and longer-term solutions that include materiel and non-materiel elements. The recommended executive strategy may contain a mix of COTS, government off-the-shelf (GOTS) and non-developmental items (NDIs); products of a rapid deployment capability targeted at slight modifications to materiel with a technology readiness level (TRL) 8 or 9; rapid development and deployment of prototypes, targeted at a TRL of 6 to 7; other research programs; and deliberate, or traditional, capability development processes."[1]
