IRW Aj'rmr

The IRW Aj'rmr was a Romulan heavy warbird in service to the Tal Shiarin the early 25th century. 

History
In 2409, a Starfleet ship in search for the missing USS Nobel (NCC-90380) triggered a satellite in the Pilatus system, alerting Tal Shiar base in the nearby Hadrian system. The Aj'rmr was dispatched to investigate. Before the Aj'rmr cloaked, the hidden Starfleet vessel marked it with a tracker and followed it to the Tal Shiar base, where an away team boarded the station.

The Aj'rmr and other vessels engaged the Starfleet ship when it retrieved its away team. The Aj'rmr was defeated and destroyed.
