EF76 Nebulon-B escort frigate/Legends

Nebulon-B escort frigate "Just once, I'd like to destroy a starship that we didn't pay for!"

- Imperial Admiral Hurkk at the Battle of Oovo IV

The EF76 Nebulon-B escort frigate was a 300-meter-long warship that was built by Kuat Drive Yards for use by the Imperial Navy, to protect convoys from Rebel starfighter actions. It was, however, used more famously by the Rebellion.

Characteristics
The standard Nebulon-B frigate was armed with twelve turbolaser batteries, twelve laser cannons, and two tractor beam projectors. It was designed to carry twenty-four TIE series starfighters.

Escort frigates were often used to support larger capital ships, such as Imperial-class Star Destroyers and Rebel Mon Calamari Star Cruisers. The frigate was known and respected for its efficiency against fighters and bombers, and both sides preferred to use the Nebulon-B frigates in anti-fighter assignments.

The Nebulon-B was originally designed to protect Imperial convoys against Rebel starfighters. However, the Rebels were able to find other uses for the ships which took advantage of their sophisticated sensors and deep-space multifrequency antennas. Escort frigates were used as long-range scouts, search and rescue ships, or to relay information to command ships during battle. In small, shorthanded Rebel task forces, Nebulon-B frigates often served as the command ship.

History


The EF76 was used extensively by both sides in the Galactic Civil War, as the Rebel Alliance also acquired a number of these ships through defection, capturing them in battle, or by outright theft.

The Rebels were not the only ones beyond the Empire to acquire Nebulon-B frigates. It was rumored that Kuat Drive Yards would sell the frigates to interested third parties through secret fronts so as not to upset the Imperial Starfleet. The sale price was 194,000,000 credits, cited as a twentieth the cost of an Imperial-class Star Destroyer.

In 3 ABY, it was onboard the EF76 frigate Redemption that Luke Skywalker received a mechanical hand after he had lost his natural one while dueling with Darth Vader on Bespin. There and then, Lando Calrissian and Chewbacca departed aboard the Millennium Falcon to commence his quest for the abducted and carbonite-frozen Han Solo.

All available Nebulon-B frigates were deployed at the Battle of Endor, where they took pivotal part in neutralizing incoming Imperial starfighters.

Variants


The Rebels converted some of their Nebulon-B frigates into medical vessels, which served as mobile hospitals. Weaponry and hangar space was sacrificed to make room for treatment facilities, bacta tanks, and hospital suites. These ships could not carry any fighters, and they were only armed with 6 turbolasers and 8 laser cannons. The most famous medical frigate was the Redemption.

Kuat Drive Yards eventually produced an improved version of the Nebulon-B, the Nebulon-B2. They were similar in performance, but had higher sublight speed and improved shields and hull armor.

Following the Battle of Endor, Kuat Drive Yards followed up on its successful Nebulon-B design with a new starship class, the 275 meter-long Corona-class frigate. Corona-class frigates were produced solely for the New Republic. Due to the fact that Corona frigates were not part of the New Republic's New Class modernization program, orders for the ships remained modest. A number of them served in the Corellian Defense Force during the Confederation-Galactic Alliance War.

Behind the scenes

 * The shape of the Nebulon-B, designed by Nilo Rodis-Jamero, was inspired by an outboard motor.




 * There is some dispute among fans on the claimed fighter capacity of the Nebulon-B. Computer games and the deck-plans in The Far Orbit Project show a hangar in the forward hull, with a launch aperture in the starboard flank, but there seems to be no such opening on the model used in the movies, and the ship lacks the internal volume to carry 24 TIE fighters without hollowing out nearly the entire forward section. Other depictions in the computer games show starfighters docking and launching via an opening in the thin connection between the superstructure and drive bay. However, the Rebel Alliance Sourcebook, seemingly the source which first introduced the Nebulon-B's starfighter capability, makes no mention of internal hangars. The text simply says that: "The escort frigate has the capacity to carry up to two squadrons of starfighters into battle. In addition, the ship has docking fixtures to accommodate ships of up to medium freighter size" (p. 60). Since The Empire Strikes Back shows the "docking fixtures" to be external hardpoints on the spar between the prow superstructure and engines, it is possible that the fighters could also be carried on a rack along the spar, in the manner of Carrack-class cruisers, assault frigates, and FarStar.


 * Additionally, some fans have speculated that some Nebulon-Bs could have been equipped with an enclosed hangar bay fitted under the spar, filling the space between the forward keel and the engine block. Perhaps added as aftermarket additions, such hangars would enable them to carry fighters like X-wings more comfortably, and Kalla's Stanchion, a ship that could belong to this subtype of the class, has appeared in Rebel Alliance hands in an issue of Star Wars: Empire. Although scaling extrapolations when compared with snubfighters shown in the same panels would suggest a size significantly larger than the 300m-long Nebulon-B, the two designs corresponds closely in appearance, and the size discrepancy may simply be a result of artistic license in the comic-book art.
