Viper 8737NC is one of the Viper Mark IIs taken from Galactica's Museum. It was originally piloted by Steady (Miniseries).
Captain Kara Thrace pilots 8737 on a Combat Air Patrol during fleet refueling operations. She pursues what she believes to be a Cylon Heavy Raider in this Viper and both are nearly lost when she dives deep in the gas giant's atmosphere. The Viper is later lost during a later CAP along with Thrace when it is crushed by the intense atmospheric pressure of the planet after Thrace descends below the hard deck (Maelstrom).
