Adriatic

The Adriatic is a ship of unknown class, but is the first ship other than the Galactica and its Vipers that is known to the audience to have weapons. It is armed with ship-to-ship missiles of a limited range.

This ship, or at least a majority of her crew, were part of Roslin's fleet.

It was in weapon's range of Kara Thrace and her party's stolen Cylon Heavy Raider when it returned from Caprica, though it did not fire. (Home, Part I)
