Des Moines — U.S.A. Tech Tree Tier X Cruiser.

The heavy cruisers designed during World War II became the epitome of their class, making them the most formidable and powerful U.S. heavy cruisers in history. After the development of a 152 mm automatic gun, the U.S. Navy High Command placed an order for a similar gun but with a caliber of 203 mm. New cruisers were to be equipped with triple-gun turrets featuring the aforementioned 203 mm guns and fitted with a thick armored deck for protection against aerial bomb attacks. USS Des Moines conducted various diplomatic and representative missions. She was also used for training cadets and in naval exercises.

Pros

Excellent main battery firepower: 9 rapidly reloading 203mm guns, AP with improved angles before autobounce and heavier shells with increased penetration, very high DPM for a heavy cruiser
Good consumable suite: Versatile utility, like the other high-tier US heavy cruisers
Comfortable ergonomics: Decent concealment, forward-concentrated firepower, allowing for powerful engagement control

Cons

Lower main battery shell velocity: The heavier shells have higher arcs, and her range is limited
Limited armour protection: Her citadel armour thickness is good, but by Tier X the simple armour scheme of the US heavy cruiser line feels vulnerable to overmatch or sustained fire
