Class
Information
D7 class
SKIN UNLOCK: Free The D7 class is a prime example of the classic Klingon cruiser design, having its warp nacelles on fixed pylons with a feather pattern, and a large spheroid forward section on a long neck.
The old, worn out Type 3 ship material is immediately available on any K't'inga variant, while the classic clean look (Type3a) is unlocked by acquiring the D7 Temporal Battlecruiser.
K't'inga class
SKIN UNLOCK: Free The K't'inga class was first introduced in the early 2270s, but despite the vessel's age its popularity among Klingon Defense Force officers remains strong. When compared to its predecessor, the K't'inga has a less bulbous forward section, more extensive external hull plating and differently-designed warp nacelles.
K't'inga class (Refit)
SKIN UNLOCK: Free The aging K't'inga class was refitted near the turn of the 25th century, updating a classic design to more modern requirements. It features a standard Klingon design with fixed wings that lead to the nacelles at the aft section of the ship, a neck stem connected to the main hull and the bridge located towards the front.
Koro't'inga class
SKIN UNLOCK: Koro't'inga Battlecruiser, 37,500 The Koro't'inga class is based on the original K't'inga class design and features a thinner neck with braces. The hull is also thinned out which is dissimilar to typical Klingon rugged designs.
The Koro't'inga is clearly based on the unused D4 design that would have featured in early episodes of Star Trek: Enterprise.
D7 class (DSC)
SKIN UNLOCK: Only with D7 Miracle Worker Flight Deck Carrier This D7-class variant is representative of the vessel as seen in Season Two of Star Trek: Discovery. The Discovery-era D7 mainly takes after the contemporary Movie-era version of the ship, the K't'inga class, with vastly different nacelles and extra detailing.
D7 class (Kelvin Timeline)
SKIN UNLOCK: Free Designated as a Warbird in the Kelvin Timeline, this version of the D7 resembles the contemporary refit version of the design, the K't'inga. It is heavily armored and outfitted with protruding port and starboard disruptor cannons.
