The Nebulon-B2 frigate, sometimes referred to as the modified frigate, was a relative of the Nebulon-B escort frigate. Though it shared a similar profile with its predecessor, the Nebulon-B2 differed in some key ways. The forward pod split into an inverted-V shape which allowed for greater surface area to mount weaponry; furthermore the connecting spar was heavier, rendering it less vulnerable to being split open by heavy fire, and the ship was about 50 meters shorter overall.
