When the Shepherd Initiative first arrived in the Azur World, they had a major problem: the loss of Solium had cost them most of their vehicle schematics. As a consequence, they were forced to begin designing their own aircraft from scratch. After the assimilation of the Blackout Assembly and the reformation into the Shepherd Remnant, access to Blackout-controlled manufacturing plants allowed these designs to enter mass production to combat both Azur Lane and the Crimson Axis in their attempt to conquer this new world.

The latest fighter from the Shepherd Remnant's assembly lines. The SEF-23 (Single Engine Fighter, Model 23) is what the Remnant was looking for; a jet fighter to stand up to Ironblood's ME-262s and dance all over everything else in a high-priority scenario. The 23 is armed with dual miniguns, two bombs, and ten pylons loaded with 4 rockets and 6 guided missiles, and can move at an alarming speed thanks to its large engine. Because of its nature compared to both its kin and competition, the 23 is relegated to being used only by the Remnant's elite pilots, whom are generally only sortied when the situation absolutely requires both a fast response and a lot of firepower.
