Penance

From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide

Penance is an agro container under the ownership of Lord Baltar in 7346.

Baltar allows its use to trojan horse both Apollo and Starbuck's Viper aboard the Aerian Administration Hub, allowing Apollo to rescue Starbuck from Osiris's clutches.

The Warriors blast away Penance's hull plates, escaping from the Hub in their Vipers (Battlestar Galactica: Starbuck 3).
