This paper model is a Sovereign Class starship, introduced in the late 24th century, showcasing some of Starfleet's most recent technological advances, based on the Star Trek series, the papercraft was created by MTK.
The Sovereign-class was introduced during the early 2370s, and was, at the time, the most advanced starship design in the fleet. The Sovereign-class USS Enterprise-E was built at the San Francisco Fleet Yards and was launched from that facility on stardate 49827.5.
The Sovereign class' first major engagements came in 2373, when the USS Enterprise saw action in the Borg incursion into Sector 001, and was instrumental in the destruction of the attacking cube.
While the Sovereign-class was not a key player in the Dominion War, such vessels as the Enterprise-E spent time during the war putting out diplomatic "brush fires" and extending the occasional olive branch, as the Federation Diplomatic Corps were busy attempting to put an end to the war.
Sometime after the Enterprise's mission in the Briar Patch and before the engagement with the Reman warship Scimitar, a refitting of the Enterprise-E took place. The major changes included 5 additional torpedo tubes and 4 additional phaser arrays. A slight change in the warp nacelle pylons was also implemented. The Enterprise was able to deploy these new systems in 2379, prior to its mission to Romulus.
Sovereign-class starships were quite adaptable to different missions, whether they be scientific, defensive, or diplomatic. These ships have 29 numbered decks. Two shuttlebays, one on the far aft of the secondary hull, similar to the hangar of the older Constitution and Ambassador-class ships, and another bay on the aft part of deck 7 were built in to the class. The Sovereign vessels were also fitted with a captain's yacht which launched from the underside of the saucer section. The class had 6 standard personnel transporters, 8 cargo transporters and 6 emergency transporters.
The class featured a warp drive modified not to have damaging effects on subspace, without the necessity of the Intrepid-class's continuum-safe variable geometry warp nacelles. The Sovereign-class had a maximum speed of Warp 9.975+.
The Sovereign-class incorporated bioneural gel packs into its computer systems. The bioneural gel in them was obtained from the Kropaslin and was designed by Doctor Delasat Vantimor.
In terms of weapons the Sovereign-class starship was fitted with a phaser array, should it be nonoperational then there was an auxiliary pulse phaser cannon that emerged from the hull. This cannon was capable of being manually operated and fired two pulse blasts along with a powered shot.
Originally, the Sovereign-class was outfitted with 12 phaser arrays and 5 torpedo tubes. Sometime between 2375 and 2379, the Sovereign-class was refitted with 4 extra phaser arrays mounted on the nacelle pylons and 5 more torpedo tubes. The USS Sovereign was outfitted with 20 phased plasma torpedoes.
The Sovereign-class could ordinarily transport up to 6500 passengers in an emergency scenario. During the evacuation of the iy'Dewra'ni refugee camp in 2381, the crew of the USS Enterprise-E were able to increase this number to over 9800.
