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
