Intrepid class

The Intrepid-class was a type of Federation starship in service to Starfleet in the late 24th century. This class starship is a cruiser as well as a science ship. It is still in use in the 25th century. (Star Trek: Voyager,Star Trek Online)

Specifications
The Intrepid-class was introduced in the early 2370s and was Starfleet's answer to their growing need for a versatile and quick class of starships which were capable of excellent maneuvering at both impulse and warp speed. With their variable geometry warp nacelles, the Intrepid's had a greater control of their warp field, with the added bonus of not damaging the subspace layer. ( manual)

As well as being designed to be quick and maneuverable in combat, the Intrepid's were primarily designed to perform exploration, survey, and courier missions. The Intrepid's advanced sensors made them an excellent exploratory vessel. 

The Intrepid-class was also one of the first Federation starship classes to be equipped to make a routine planetfall and be able to take off again with ease. 

The Intrepid's were also equipped with some of the most advanced computer systems of the time, with bio-neural circuitry replacing most of the isolinear circuitry that had been prevalent on previous starship classes. The bio-neural circuitry sped up the computer's data functions and improved overall performance. 

Service history
Initially the construction of four vessels were approved by Starfleet Command: the prototype USS Intrepid (NCC-74600), USS Voyager (NCC-74656), USS Stargazer (Intrepid class), and the USS Pathfinder (NCC-74562). 

The first two ships to be constructed, the Intrepid and Voyager, were launched from the Utopia Planitia Fleet Yards at the end of 2370 and the beginning of 2371 (stardate 48038) respectively. 

By late 2377, there were dozens of Intrepid-class starships in operation, and many were involved in operations against the Borg in that year.
