The Nebulon B2 was originally created to make up for the major design flaw in the original EF76 Nebulon-B escort frigate. This flaw was the very thin spire between the front part of the ship and the engine block, which could be bombarded by even fighter-scale ordinance, causing it to snap in half and vent most of the atmosphere, killing virtually the whole crew. The front prow is also split in an inverted V shape, presumably to increase space for mounting weapons, but the real reason remains unknown.
