Ships of 2245-2271

Ships in service to the Starfleet from 2245-2271.

## Constellation

* Timeframe: 2268-2270
* Built: 4
* Type: Cruiser

The Constellation Class was made in a limited test-basis in 2268 to test the feasibility of a four-nacelle design. Engineers sought to trial the ability of a ship to balance a warp field by alternating between four nacelles. The design came in at the end of a design era, and the shift in the direction of the 'Constitution Refit' meant that this ship class was delayed in production until 2275. The first ship was refit into the new design language, while the other three were deemed not worth the cost of refit and sold to private citizens. The USS Constellation, NX-1974 was rechristened in 2275, when the Stargazer, Newton, Herschel, and Eddington were christened and released. The ships were more powerful, but had issues balancing the intermix ratios for the first few hundred light years.

## Constitution

* Timeframe: 2245-2269 (in this configuration); -2395 (in newer configurations)
* Built: 13 (Mark 1, 2245-2269); 28 (Mark 2, 2259); 6 (Mark 3, 2269)
* Type: Cruiser
* Crew: 230 (Mark 1); 420 (Mark 2, 3)

One of the most widely known and widely sought after ship postings, the Constitution class had some of the latest and most advanced systems when launched in 2245. The first thirteen ships went on to participate in some of the most challenging missions, resulting in a class-wide refit being officially ordered starting in 2259, with a new set of engines, a new bridge module, and several new systems, including new phaser, torpedo, and shield systems. The Enterprise finally got its refit at the end of Captain Pike's second five-year mission, before the ship was transferred to the command of Captain Kirk. Initial testing of the systems went well, though after a particularly trying mission, the Enterprise had several updates out-of-order with other ships (the bridge, deflector dish, and warp nacelles).

## Derf

* Timeframe: 2243-2268
* Built: 545
* Type: Tender

## Hermes

* Timeframe 2231-2265
* Built: 419
* Type: Scout

The Hermes Class is very similar to that of the Sheridan Class, with the difference of equipment layout. It has a crew of 180, 4 shuttle, a top speed of warp 8, with 4 phaser banks, and 3 torpedo tubes (2f/1a).

## Kelvin

* Timeframe: 2232-2267
* Built: 22
* Type: Scout

## Kiev

* Timeframe: 2264-2270
* Built: 14
* Type: Frigate
* Armament
	+ Phasers: 6 banks of 2 turrets dorsal and ventral fore, port, and starboard
	+ Torpedoes: 2 fore, 1 aft

## Loknar

* Timeframe: 2233-2269
* Built: 99
* Type: Frigate
* Length: 290 m
* Beam: 127.1 m
* Draft: 56 m

The Loknar Class starship is an Andorian-inspired starship, and for a good while was nearly entirely crewed by Andorians. They were popular ships that saw action during the Axanar War an in a number of border disputes with the Klingons and other nearby species.

## Miranda

* Timeframe: 2235-2270
* Built: 39
* Type: Science Cruiser

## Nelson

* Timeframe: 2236-2265
* Built: 104
* Type: Destroyer

## Nimitz

* Timeframe: 2255-2269
* Built: 89
* Type: Shuttle Carrier

The Nimitz Class carrier filled a gapa in Starfleet's forces by providing a shuttle carrier for capable shuttle-fighter-based combat. Fighting in the Triangle against the Daltari, the USS Nimitz and USS Eisenhower proved themselves capable with against several Daltari battleships. The shuttle fighters had smaller power-banks for their phasers, but they successfully drained enough power from the shields to allow the carrier itself to overwhelm and destroy four of the 7 ships, leading to a Daltari withdrawal. While not as maneuverable, the ship makes up for it in its potential combat ability.

## Ptolemy

* Timeframe: 2232-2268
* Built: 288
* Type: Cargo Carrier / Transport

The Ptolemy Class ship is a transport ship, and is one of the most commonly seen ships across the Federation. It is often used in transporting colonists to new worlds, as well as bringing materials to new systems for base construction.

## Sheridan

* Timeframe: 2231-2262
* Built: 51
* Type: Destroyer

The Sheridan-Class destroyer has a crew of 195, and a speed up to warp 8 in emergencies, with two dorsal and two ventral phaser banks on the saucer, and one aft single turret on the warp pylon, and dual forward and one aft photon torpedo tube. It was named for General Sheridan, with other ships of the class being named for other US cavalry officers.

## Stuart

* Timeframe: 2236-2266
* Built: 40
* Type: Destroyer

The Stuart Class was named for General J.E.B. Stuart, and one of a series of ships with a highly modular design, allowing Starfleet to expand rapidly in the first half of the 23rd century with the highly modular designs, despite criticism of the very visually similar ships being produced across the Federation. This ship had a crew of 200 over the life of the design, with a maximum speed of Warp 9.
