This ship the Avenger was formerly a ship of the Imperial Navy which had decided to go rouge and be a Rebel Privateer. However soon after they started a third Nebulon-B Escort Frigate arrived in the Kharak System. The crews at New Hope would immediately get started on two Alliance Nebulon-B Escort Frigates docked with the shipyard, the Shooting Star and Valiance. The two engineers would after a few days of heavy discussion come up with the new design: the EF78 Nebulon-B2 Heavy Frigate. The team at New Hope would once bring in noted starship designed Walex Blissex along with newcomer Rory Swann a former engineer at Kuat Drive Yards who had led his entire team to defect to the Alliance. This project would be handed over to the now experienced hands of engineers at New Hope Shipyards who had been successful in the design of the Alliance Class Assault Frigates. Like the weakness of the center spar of the ship which is how the Salvation was destroyed during the battle. It would be thanks to this compliment that really allowed the ship serve at the head of any Rebel Fleet.Īfter the disastrous Battle of the Itani Nebula and loss of the Alliance Fleet Flagship Salvation, a Nebulon-B Escort Frigate saw the start of a project to redesign the venerable Escort Frigate to fix some of the weaknesses of the design. This hanger allowed the ship to carry three full fighter squadrons plus supporting shuttles. Unlike the original Nebulon-B Escort Frigate the newer Nebulon-B2 sported a dedicated starfighter hanger bellow the forward hull between the two plyons of the inverted-v section of the ship. Combined this with the heavy JC-671 Type Shield Generator and its lighter backup unit made the Nebulon-B2 Heavy Frigate truly a robust and well armed ship. The ship happened to be exceptionally well armed for its size sporting three medium duel-turbolaser turrets, sixteen light turbolasers, twenty laser cannons, and two concussion missile launchers. It also served as the Fleet's heavy hitter alongside the older Alliance Class Assault Frigate though the Nebulon-B2 was a bit more powerful thanks to its extra weapons.

The Nebulon-B2 was designed to be the centerpiece of any Alliance Fleet, making it normally a command ship of smaller Alliance Fleets. Also the center spar was reinforced and slightly heavier rendering it less vulnerable to being split open by heavy fire which was one of the main weaknesses of the Escort Frigate design.

Most of this noted width was thanks to the inverted-v the forward hull split into which reinforced and secured the forward part of the ship. It measured out as three hundred twenty five meters long, and a hundred forty five meters wide at the front. The design of the Nebulon-B2 Heavy Frigate looked similar to the older Escort Frigate design just a bit larger and far more powerful.
