After six months of space trials proved uneventful, an additional five Flight I hulls were approved and allocated to the Fifth Fleet to serve as a proof-of-concept for newly developed carrier warfare doctrine. In, the first production and Flight I model of Hammerhead, UEES Hammerhead was transferred to the UEE Navy. Aegis had built a fast warship nimble enough to properly support a battle group while remaining inexpensive enough to be constructed in large numbers. The result of the prototype program was a highly successful new spacecraft design. Structural development lasted eighteen months, followed by three years of construction on the first of six test-bed articles. Six initial prototypes were built by Aegis, with two of these prototypes being delivered to the UEE Navy for evaluation. Aegis Dynamics was tasked with developing this new warship, then identified as PROJECT MONITOR and began ground-up development that November. In March 2765, High Command issued a request for proposal (RFP) seeking a dedicated anti-fighter platform that could serve as both a key element of the standard fleet screen and as a cost-effective patrol ship to replace the aging Guine-class.
