Starfleet Modernization Program

The Starfleet Modernization Program was a standardization project by the Starfleet, implemented in the early 2370s. The project was implemeted as a result of the increasing number of wars the Federation was fighting and the increasing need for more warships designs in Starfleet, rather than explorer designs. The project was critisised by many Starfleet officials for its supposed "militarization" of Starfleet. The name also referred to starships developed as a part of the project.

Origins
Starfleet consisted mainly of small frigates built mainly for exploration. As conflicts with other factions increased in the mid-to-late 24rd century, such as the Cardassians, Borg, and the Dominion, the need for mainly warship designs became clear.

Defiant class
The Defiant-class starship, officially an escort, began development around 2367 as a small, highly-powered, heavily-armed warship intended to defend the United Federation of Planets against the Borg.

The Defiant prototype was pulled out of storage in 2371 when the Dominion threat emerged. After several upgrades by Deep Space 9 Chief of Operations Miles O'Brien, the ship was deemed worthy of use and more ships of the class were constructed. This class was the first of four classes in the Starfleet Modernization Program.

Sovereign class
The Sovereign-class starship was introduced in the late 24th century, showcasing some of Starfleet's most recent technological advances. As of 2387, there were 87 starships of this class in service.

Titanic class
The Titanic class was a class of Federation deep space starship in service to Starfleet in the late 24th century. The first Titanic class ship was commissioned in the year 2378. As of 2387, ten Titanic class ships had been built.

Vesta class
The Vesta-class was type of Federation Starfleet starship in service from 2380. The class was designated a multi-mission explorer and was test-bed for a number of experimental technologies, including quantum slipstream drive. As of February 2381 there were seven vessels of the class in service.

Daedalus class
The Daedalus-class, also known as the 304 or Daedalus class warship, is a class of deep space carrier built by the Federation in 2379. As of 2387, eleven Daedalus-class warships had been built. These 304s are the Daedalus, Odyssey, Korolev, Apollo, Sun Tzu, Orion, Fraiser, Aurora, Tria, Phoenix and the George Hammond. As of 2387 eleven Daedalus class starships are known to be in active service. One 304 the Sojourner was destroyed in 2387 during the Battle of Capella IV by the Narada.
