Indomitable class

The Indomitable-class was a Federation class XII battleship starship in Starfleet service in the 23rd century, becoming active on reference stardate 2/2208. A mark II uprated modification entered service on stardate 2/2303.

The Indomitable was created in the late 23rd century as a battleship modification of technology created for the refit heavy cruiser. Mark I Indomitable-class vessels crewed 580 officers and men, with room for up to 20 passengers, while the uprated mark II required 620 crew. Additionally, the Indomitable could carry 27,500 metric tons of cargo, rated at 550 SCU (standard cargo units). The mark I vessels weighed 182,165 metric tons, and the uprated mark II was 185,945 tons. The Indomitable measured 543.7 meters in length, 224.2 meters in width and 92.2 meters in height. The Indomitable had six standard (6-person) personnel transporters, six 22-person escape transporter stages and three cargo transporters. The control computer of the mark I Indomitable vessels was of the M-7 type, while the mark IIs had M-8 computers.

The Indomitable mark I warp engines were FWG-1 type, while the increased mass of the mark II used FWG-3 units, rated to cruise at warp factor 8 and max out at warp factor 9.9. The Indomitable impulse engines were of the FIG-2 type. The Indomitable weapons consisted of four dual-emitter FH-411 phaser banks, a total of eight phaser emitters, with forward, aft, port and starboard firing arcs. The mark I vessels had four FP-4 photon torpedo launchers with forward, aft, port and starboard firing arcs, while the mark II had an additional two launchers, bringing the total to six. Indomitable was defended by FSP model deflector shields.

The Indomitable-class history began shortly after the USS Enterprise was involved in the V'Ger Incident of 2273, with a successful test of new systems. Starfleet approved plans to build a battleship class based on reports being received from Project Dixie and Project Grey Ghost, with Starfleet Intelligence reporting that the Klingons were aspiring to build a successor to the, and that the Romulans were about to start construction on a new battleship. The approved Indomitable design was an affirmation for Daystrom Data Concepts with the first practical use of the M-7 computer. Construction began on the first four ships at the Earth's shipyards on stardate 2/2012.
