These are the cover artworks for Neuromancer, Count Zero, and Mona Lisa Overdrive by Josan Gonzalez (Deathburger). The covers were used for the Brazilian reprints.
Deathburger makes a bunch of cyberpunk art in this style and he posts a lot of it to his Instagram page.
They don’t usually directly. I think they are just stylized ships and platforms to evoke the feeling of space battles.
