Krenim warship
The Krenim warship was a type of warship utilized by the Krenim during the 24th century. These vessels were larger and more powerful than an  starship, due to, in part, their complement of chroniton torpedoes.

History
In an alternate timeline experienced by Kes while she was living her life in reverse, the  encounted a Krenim warship in the first engagement of the "Year of Hell", and suffered significant damage because of its initial inability to compensate for the temporal variance of the Krenim torpedoes. Thanks to Kes' assistance, as a result of her time shifts, Voyager was able to counter the temporal variance and disable the Krenim warship's torpedo launcher. ()

Voyager later encountered a Krenim warship in 2374, after the Krenim weapon ship destroyed the Zahl homeworld. They would continue to be hounded by these vessels throughout the year, to the point of nearly destroying Voyager, before Seven of Nine devised a temporal shield to protect the ship. This class of vessel was erased from the timeline – along with a large area of the Krenim Imperium – following the destruction of the Garenor homeworld by the weapon-ship, and was replaced by the Krenim patrol ship.

Following the destruction of the weapon-ship, the restored timeline saw the Krenim using this vessel. ()

31st century temporal agent  had the schematics of the Krenim warship in his database that he brought to the 22nd century. Captain Jonathan Archer scrolled past the schematics in 2152. ()

Background information 
The studio model for the "Krenim Warship" was designed by Rick Sternbach. Sternbach's direction for designing the Krenim warship was simply a "retro, deco style." After "a few pages of loose doodles" looking to find a shape that was different than others firmly established, he colored the design with a bronze and reddish-pink hue. (Star Trek: The Official Starships Collection, Issue 149, pp. 10-11) 

Specifics about the vessel revealed that its length was approximately 500 meters, and it had a maximum speed of warp 6. (Star Trek: The Official Starships Collection, Issue 149, p. 2) , suggested the Krenim warship had a crew of about 30.
