Deepwater Yard

The Deepwater Yard is the third level of the Naval Yard: everything the Advanced Naval Yard builds, plus the Sovereign Battleship, the Kraken, the Moray and the Aircraft Carrier. Upgrading to it needs a Radar Station standing, and the line builds nothing for the 48 seconds the upgrade takes.

How to use

The Kraken and Moray are submarines for doing things unseen: shelling a shore from water nobody is watching, and landing a squad on a coast nobody is guarding. Neither can fight a ship, so the surface fleet the Advanced Naval Yard already builds is still the fleet; these boats handle the covert side of naval warfare. The Sovereign adds long-range heavy guns for bombarding the shore. Upgrade it on an island map, where the ore is out in the water and the enemy's coast is long, and keep an Aegis or a Cormorant of your own about, because the enemy's answer to your submarines is the same as yours to theirs. The Aircraft Carrier brings a flight deck and ammunition supply to the fleet, with 10 cargo capacity for aircraft. Its light defenses need Aegis escorts. Lose the radar and these four units leave the build menu until it stands again.

With your completed Headquarters Lv.2 standing, Engineers can also build this line directly at Lv.3 for 1,750 metal, taking 96 seconds. The Radar Station and a free production slot are still required. A line already founded keeps building if that HQ is lost.

Trivia

• The Deepwater Yard gained the Aircraft Carrier on October 1, 2026. Its strategic roster then included both a submerged missile launcher and a floating airbase.
