USS Des Moines, as the lead ship of the Des Moines class, has an armour layout which is based off the Baltimore class heavy cruisers. The main benefit for the main armour belt was to provide protection for the forward magazines, increasing the protection underneath the forward turrets from 0.75 inches to 5.8 inches of armour. The main armour belt is slightly thinner as the Baltimore class has a 6-inch belt, but the extra coverage which the extended belt provides is very welcome. The fore and aft of the citadel are protected by 4.8 inches of bulkhead armour, and thin 0.75-inch bulkheads interspersed throughout the citadel. The decks above the citadel are protected by 1-inch of anti-fragmentation armour just like the destroyers in the US tree. Lower in the ship is a 3.4-inch deck armour plate to deal with incoming fire from long ranges as well; this can deal with other cruisers and lower, however battlecruisers and battleships will easily penetrate this.

Des Moines has excellent armour on the turrets, with 8 inches of armour on the turret face, angled at 34 degrees to provide extra protection. This renders the turret face essentially impervious to any cruiser or destroyer fire, so long as it is facing towards the enemy. The turret sides, with only 3.75 inches of armour, can be penetrated by all cruiser calibre and many destroyer calibre guns at close range. The roof is better protected to defeat plunging fire, with 4 inches of armour. The barbettes have less armour, with 6.1 inches of protection. These will be knocked out regularly by other heavy cruisers and every battleship. These lead into the magazines, and the second turret magazine in particular. It is placed in an exposed position above the waterline unlike the Baltimores, so every precaution should be taken to avoid taking fire to this section. When fighting the Des Moines, this is the recommended area to hit.

Similar to other American cruisers, she lacks torpedo bulges, instead relying on fuel tanks along the hull. These cover the entirety of the hull between the turrets, and can absorb some smaller torpedoes, though most will easily punch through. Captains should watch out for torpedo attacks at all times. If taking a hit is inevitable, manoeuvre the ship so that it takes the hit as close to the front of bow as possible, as the bow is mostly empty space and Des Moines can survive a hit here with just some flooding. Any hits below the turrets, especially the second, should be avoided at all costs.

Mobility

Speedforward / back

AB71 / 29 km/h

RB61 / 25 km/h

Possessing a flank speed of 33 kn, USS Des Moines has the same top speed as other American heavy cruisers such as the USS New Orleans or the Baltimore-class, and slightly faster than the Brooklyn class. This speed allows Des Moines to make it to capture zones and other key locations at a reasonable pace, though not quite as some other cruisers such as Voroshilov. This speed drops to 23 kn in a turn, which although leaving her as an easier target, is still faster than any of the American battleships' flank speeds.

The rudder takes roughly 2 seconds to cause the ship to begin a turn, and while USS Des Moinse is responsive, at essentially 21 tons displacement there is a limit to just how quickly she can turn. Des Moines is agile for a heavy cruiser, but captains will need to be wary when traversing narrow passages as she is unable to make many of the turns that a destroyer or light cruiser could make.

Some ships are fitted with weapons of various calibres. Secondary armaments are defined as weapons chosen with the control Select secondary weapon. Evaluate the secondary armaments and give advice on how to use them. Describe the ammunition available for the secondary armament. Provide recommendations on how to use them and which ammunition to choose. Remember that any anti-air armament, even heavy calibre weapons, belong in the next section. If there is no secondary armament, remove this section.
