Like the K'T'inga Class Cruiser, the Vas'Kalabam is an effort to update the D7 Battlecruiser to modern technology. The Romulan refit is at best a half-hearted upgrade. The main design change involves improved sensors and the exchange of outdated torpedo technology in favour an expanded suite of plasma mortars.

The increased demand on already ancient reactors required the removal of several smaller weapons; however, as the ship was falling into a fleet support role, the decrease in short range firepower was found to be acceptable. Shield technology was replaced with modern units but any gain lay in the availibility of replacement parts; the new shields not providing increased protection. Because of the limited number of hulls originally purchased from the Klingons and subsequent losses, the Vas'Kalabam is a rare sight at best.
