Description and Notes
The Breen ships are quick vessels, heavily armed cruisers, easily a match for most Starfleet ships. Its EMP Weapon drains all energy of the hit target (50+10d6 per round) making it inoperational within seconds. Starfleet was able to modify its ships' warp cores in a way to render a protection against this weapon.

Note: Although being described as large ships in the Deep Space Nine Core Rulebook, I recognized them only being slightly larger than the Defiant in the series.
