Warhammer, from Gothic Fleet to Azur Lane

The Imperial Navy has always been a thing with little presence in Warhammer 40k.

GW: The big event of Warhammer 40k has begun. The Astropath died suddenly, the Warp Storm hit, the main force of the fleet was intercepted outside the system, and the remaining fleet fought desperately to defeat the enemy, forcing the opponent to fight a decisive battle on the ground. The Astra Militarum and the Astartes fought side by side and won a tactical victory after suffering heavy casualties.

Salmin: You are right, but the Emperor’s Vision is a brand-new command aircraft carrier independently developed by the Mechanicus. I forgot the middle and the end.
