Avenger class (battlecruiser)

The Avenger class was a type of battle cruiser that was developed by Starfleet in the 25th century.

They were developed following the war with the Klingon Empire where Starfleet engineers began designing a vessel that could wage war yet still be used for exploration missions. The product of the program was the Avenger class battle cruisers that was made to be a combat vessel. It was smaller than standard cruisers as it was created to be more agile yet still be able to take damage. These starships were made to be gunships with a more aggressive style compared to traditional vessels from the United Federation of Planets. (STO website: Avenger Class Battle Cruiser)
