The Krenim warship was a Krenim starship class, a tier 6 warship in service to the Krenim Imperium from the 24th century. In the early 25th century, it became the warship for the multi-species Krenim Coalition. The Krenim warship was armed with temporal weaponry and systems. (VOY episodes: "Before and After", "Year of Hell", STO video game: The Iconian War [Year of Hell Lockbox])

History and specifications


The Krenim warship was a large ship, equaling or dwarfing significant starships like the Federation Intrepid-class science vessel, the Zahl heavy cruiser or the Nihydron destroyer. It was smaller than the Krenim temporal weapon ship. (VOY episode: "Year of Hell", STO video game: The Iconian War [Year of Hell Lockbox])

Weapons and systems

In the 2370s decade, the warship's primary weapon were chroniton torpedoes. Because they were phased weapons the torpedoes could bypass deflector shields except for temporal shields. (VOY episodes: "Before and After", "Year of Hell")

In the 2410s, additional weapons were part of the complement: The Krenim warship featured five forward facing and three rear weapon slots. These slots could be equipped with blue standard energy weapons, cannons and torpedo launchers.

Additional systems included the timeline analysis sensor grid and the potentiality starship trait. The sensor grid was a universal console, meaning it could be equipped in place of any engineering, science or tactical console on the ship. The sensor grid would perform a timeline analysis on enemy targets to gain a tactical advantage by adversely affecting causality within the target, effectively decreasing the combatant's defenses. As a side effect, the sensor grid console improved the accuracy of cannon weapons. The console could be removed from the warship and equipped on any other Krenim Coalition starship.

During its service period, the crew's mastery of the ship would improve by level and enable the potentiality starship trait upon reaching level 5. This trait allowed to utilize potential energies unleashed by alternate timelines where different choices were made by the crew. These potential energies temporarily increased the weapon damage output.

Krenim warships were slower and less maneuverable than destroyers and escorts but featured stronger deflector shields and a more durable hull. (STO video game: The Iconian War [Year of Hell Lockbox])


A Krenim warship had a crew of 300 officers. Through the Lobi Crystal Consortium, the Krenim warship was made available for commanding officers from the Alpha Quadrant Alliance. The minimum rank for an eligible officer was rear admiral (Starfleet), brigadier general (Klingon Defense Force) or subadmiral (Romulan Republican Force).

The ship was commanded from a bridge equipped with the following stations: 1 tactical officer with the rank of commander, 1 lieutenant commander as science officer, 1 lieutenant commander of any department who was also a pilot, 1 lieutenant tactical/intelligence officer, and one ensign engineer. (STO video game: The Iconian War [Year of Hell Lockbox])


In the 2370s decade, Krenim warships patrolled the territory of the declining Krenim Imperium to ward off the Krenim's enemies. In the year 2374, one such ship made first contact with the United Federation of Planets, represented by the starship USS Voyager. The warship's commandant advised Voyager's captain to avoid this area of space, spatial grid 005, because it was in dispute. Voyager heeded the advice. (VOY episode: "Year of Hell")

In 2410, the small Krenim Imperium was no match for the eradication campaign of the Vaadwaur Supremacy. (STO - The Iconian War mission: "Time in a Bottle")

Krenim warships returned from hiding when the Krenim allied themselves with the Alpha Quadrant Alliance to fight their common enemy, the Iconian Empire and its servitor races. When the Krenim Imperium became a founding member of the Krenim Coalition, the Krenim warship became its most powerful starship class. (STO video game: The Iconian War [Year of Hell Lockbox])

When the scientist Noye defected from the Delta Alliance, Krenim officers loyal to him followed, and he controlled a fleet that included Krenim ships. Led by the Annorax-class dreadnought KIS Annorax, Krenim warships followed Noye into another time. (STO - Future Proof mission: "Time and Tide")

Across a timeline possibility range of 79.57-100%, the Imperium decommissioned the warship in 2436 due to advances in subspace field generators rendering the warship's propulsion systems obsolete, and too costly to refit. (Adventures RPG module: Delta Quadrant Sourcebook)

In the 26th century, Krenim warships were part of the combined Sphere Builder and Temporal Liberation Front that stood against the Federation fleet led by the USS Enterprise-J in the Battle of Procyon V. Despite multiple temporal changes, the Federation won the engagement. (STO - Future Proof missions: "Ragnarok", "The Battle of Procyon V")

In 2769, Noye arrived with his fleet at New Khitomer during the signing ceremony of the Temporal Accord and announced the formation of the Temporal Liberation Front (TLF). Noye's fleet engaging the Galactic Union included Krenim warships. (STO - Future Proof mission: "Time and Tide")

Alternate timelines

Affected by a temporal incursion

In an alternate timeline were Kes jumped backwards in time from 2379, warships of this class were used by the Krenim Imperium to defend its expansive empire from all invaders. These ships use chroniton based torpedoes that are capable of penetrating Starfleet shields as they were out of phase with the rest of the spacetime continuum. The USS Voyager was eventually able to develop a defense against these weapons but not before losing a majority of the ship. (VOY episode: "Before and After")

In an alternate timeline were the Krenim temporal scientist Annorax built the Krenim temporal weapon ship Kyana Prime and launched it in the 22nd century, Krenim warships were used by various iterations of the Krenim Imperium affected by the Kyana Prime's temporal incursions. After the Krenim temporal weapon ship was destroyed and the timeline restored, the Imperium continued to use the warship. (VOY episode: "Year of Hell")
