Blue squadron is one of the viper squadrons attached to Battlestar Galactica. Blue Squadron is led by Captain Apollo.
History
Blue squadron sees action during the Battle of Cimtar, engaging the overwhelming numbers of Cylon Raiders. When Galactica disengages from the battle to attempt to protect the Colonies from the basestars, blue squadron is left to fend for itself until Galactica returns.
Elements of blue squadron fend of the Cylon ambush at Carillon, fighting off the Raiders, and even using deception to destroy a basestar (Saga of a Star World).
When most of blue squadron's pilots are infected by a mysterious illness, female shuttle pilots are trained to fly in their place. The shuttle pilots successfully engage and destroy a Cylon outpost, escorting a shuttle with medical personnel aboard in order to try to cure the illness that had affected the Viper pilots (Lost Planet of the Gods, Part I).
The female fighter pilots are able to hold off a Cylon attack over Kobol, and are joined by the male Viper pilots (who had just barely recovered from the illness) in driving off the Raiders (Lost Planet of the Gods, Part II).
Adama refuses to launch blue squadron to intervene when Apollo is isolated by a Raider attack and draws the pursuit away from the Fleet. A small recon patrol later recovers blue squadron's commander (The Lost Warrior).
Some new Viper pilots are being trained on a patrol when blue squadron encounters the Ravishol pulsar. The pulsar kills Shields and Bow, and Cree is forced to the surface of Arcta (The Gun on Ice Planet Zero, Part I). A small commando force destroys the pulsar and rescues the downed pilot (The Gun on Ice Planet Zero, Part II).
