This star trek papercraft is the Akira Class Starship, designed by ikenohata. The Akira class was a class of Federation starship that was in service with Starfleet by the early 2370s. Utopia Planitia Fleet Yards was one of the sites this class was constructed at in 2371.
Akira-class starships were featured prominently in the Battle of Sector 001 and the Dominion War. Several Akira-class ships were stationed near Deep Space 9 during the war.
As well, several were involved in most of the major battles of the war. In 2374, they saw action during Operation Return and the First Battle of Chin'toka, where at least two ships of the class were destroyed by orbital weapon platforms. In 2375, they were involved in the Second Battle of Chin'toka and the Battle of Cardassia.
A design sketch of the USS Akira shows the vessel bearing the registry NCC-2497. In an unpublished interview with author Larry Nemecek, designer Jaeger said he simply used the four-digit number of his then-phone extension for that registry; to conform to Starfleet practice, the number "6" was added by Mike Okuda and the film's art department to make "62497," a number then approved by producer Rick Berman. At the same time, Jaeger said, two other ship names and registries were approved as back-ups, if needed, to the USS Thunderchild actually seen on film as NCC-65549: the USS Rabin as NCC-63293, and the USS Spector. The ship scale sheet showing the back-up names and registries can be found on John Eaves' blog.
Neither of the latter ships ever appeared on screen, although the CGI file used for the Akira-class seen in the Voyager episode "Message in a Bottle" was numbered NCC-63549, ostensibly the Spector, and was used by the Star Trek Fact Files. The ship allegedly appeared in one of the battle scenes from the sixth and seventh seasons of Star Trek: Deep Space Nine, but this has not been verified.
