There are dev statements to the effect that the Abyss ships are sunken ships from both sides that reincarnated because of lingering grudges and so on. Essentially they're yuurei. However, those ships all use imperial measurements, and the Fall 2013 event was designed as a homage to the battle of Guadalcanal. Some of the regular maps are also inspired by IJN campaigns; world 4 is a thinly veiled tribute to the Indian Ocean Raid, and world 5 is influenced by Guadalcanal (again).

Despite what they're saying, it's safe to assume that the Abyss ships are representative of the US Navy.
