Breen Frigate

The Breen Frigate is known to Starfleet primarily from USS Courageous' engagement against a Breen task force near the Romulan border and intelligence reports on the conflict with the Romulans. The Breen Frigate is optimized for scouting and skirmish duties, combining a strong science suite with middling mobility, but relatively fragile as demonstrated by two of them dying under the guns of Courageous before she was crippled. The Romulans also targeted these ships heavily during their war against the Breen to reduce the Breen advantage at scouting.
