I-31 (Comet Trail) Class VII Armed Freighter

«Last Updated – December 15, 2020»

Romulan-I31

design by Morgan Donivan

Known Sphere Of Operation:  Empire-wide use
Data Reliability:  C
Major Data Source:  Romulan Sector Intelligence

NOTES:
The I-31 is as unpopular with officer and crew alike as nearly all other Klingon ships purchased during the technology exchanges, and yet is undeniably one of the more capable vessels fielded.

Unlike most Romulan freighters, the I-31 is heavily armed and easily able to defend it self during combat. Its smaller cargo capacity belies it’s sustainable speed and long range capability. The I-31 also has some of the heaviest weapons available to the Empire. When first scanned, it was believed that the I-31 was possibly a Romulan “Q” ship, but no other variant has been detected. It is known that the Romulan requested that the KIE impulse drive be included.

Because of it’s heavy firepower, the I-31 is often used as a support freighter during major combat operations. When not part of fleet deployment, the I-31 is only observed in the company of other I-31s and heavy escort ships. This may indicate that the I-31 is used primarily to transport high-value cargoes.

Intelligence reports that only 35 of these ships were traded and refit. It is unknown if the Romulans requested more Klingon G-11s, but the unpopularity of that vessel may indicate that the Klingons traded more hulls before the technological exchange fell apart.

This I-31 is named for a large bird that has a massive long flight tail that resembles a comets tail in flight.
