D'dhael Aish'anh class

The D'dhael Aish'anh-class warbird (Federation Standard: War Eagle-class; literal translation "great bird of war") was a class of super-heavy cruiser or dreadnought fielded by the Romulan Star Empire's Grand Fleet beginning in the late 23rd century. It was a predecessor to the of the mid-24th century. 

History
Two D'dhael Aish'anh-class warbirds, ChR and, were fielded by the Grand Fleet as part of a pacification action against the rebellious colony Artaleirh in 2276. During the subsequent Esemar was destroyed by the USS Enterprise (NCC-1701), while Gauntlet was severely damaged by the renegade Grand Fleet vessel. 

At least one member of the class, Gauntlet, survived into the early 25th century as a museum ship in the Artaleirh system. By 2410, however, the Fleet was so short of combat-worthy ships that Gauntlet was refitted with parts cannibalized from two BER warbirds and pressed back into service as a patrol vessel.

Technical data
When built the D'dhael Aish'anh-class warbird was one of the most powerful vessels in the fleet. They were also among the first ships to employ an artificial black hole as the primary power source. They featured four warp nacelles, which were vulnerable to attack as demonstrated at Artaleirh.
