NOTES:
The T-21, introduced in mid-2277, was intended to be a “middle-ground” design between the T-5 and T-10 class destroyers. The T-21 was similar to the T-10 in that it had both beam and missile weapons. Unlike the T-10, though, the T-21’s primary missile weapon was the powerful RPL-3 plasma torpedo rather than the emerging photon torpedo systems found on the T-10.
The end result was a combat platform that had less overall firepower than the T-5 yet technically more than the T-10. Defensively, the T-21 was superior to it’s counterparts.
Supporters of the T-21 within the Romulan Star Command were considered some of the more aggressive members of the Romulan military. Line commanders assigned to the T-21 soon developed a reputation for being extremely vicious in combat, using the massive firepower of the RPL-3 at point blank ranges to devastate enemy vessels. This tactic and led T-21 commanders to adopt the moniker of “Hhnoiykar-ait”, which was also a reference to the class name taken from a sub-species of hhoiyakar – or Romulan weasel. These rodents were known for a distinct vocalization before attacking their prey; they were also known for being bad tempered.
The Type-2, introduced in 2285, upgraded the primary impulse engines, main computer, weapons and shield system. The additional power from the enlarged impulse drive made the Type-2 even more dangerous.
Both the Type-1 and Type-2 are believed to still be in production. Corril and Romulus seem to be the most likely production centers. Of the 35 vessels believed to be fielded, only one is known to have been destroyed.
