Y-wing scout bomber

The Y-wing scout bomber was a prototype starfighter that shared similarities with the BTL-A4 Y-wing assault starfighter/bomber used by the Alliance to Restore the Republic. The scout bomber was a small one pilot fighter that supported the presence of an astromech droid in a astromech socket. As the name suggests, the Y-wing was roughly oriented in the shape of a 'Y,' with a forward facing cockpit with two engines attached to the rear of it on either side. The starfighter boasted four laser cannons: two forward facing guns next to the cockpit, and a rear pair of guns attached to the astromech socket. The starfighter also featured a bomb bay so it could function as a bomber.

Prior to or during the standard year 3 BBY the Jedi Knight Kanan Jarrus and the astromech droid C1-10P flew a scout bomber and discharged its weapons. This particular scout bomber had an off-white colored hull with yellow markings. The crest of Phoenix Squadron, a facet of the rebellion, was painted on the rear of the cockpit.

Behind the scenes
The Y-wing scout bomber was an original creation of Hasbro Inc. that first appeared in their Star Wars: The Clone Wars toy line, which existed within the Star Wars Legends continuity. The Y-wing scout bomber was canonized when Hasbro repainted and re-released the toy as a part of the Star Wars: The Force Awakens toy line, although little of its original backstory was retained.
