Nice. I like the obvious influences from the Albatross, Fokker D.VII, Airco DH.2 and Farman MF.11 in the fighters. The ship itself is pretty reminiscent of the Japanese heavy cruisers, especially the Aoba class, with some details from HMS Hood.
There's kind of a funny story behind the name, but it contained so many plot points that wouldn't make sense without context.
Basically, the Ghost Fleet is the Czarist Russian element of the Martian Punitive Expedition that 'went native' after the revolution. They're something of a wild card, and both the Central and Allied powers have tried to draw them into the broader conflict that happened later.
I'm glad you like it. Things should be better fleshed out in the final work.
