Assault destroyer

The destroyers were medium sized marine vessels of the Allied Forces in the Great World War II and the Great World War III and formed the backbone of the Allied navy. They were designed to be endurant yet maneuverable and versatile against many kinds of targets.

GWWII
The Arleigh Burke class guided missile destroyers were medium sized marine vessels of the Allied Forces in the Great World War II and formed the backbone of the Allied navy. Relatively fast by naval standards, they were also fairly resiliant. Additionally, they were capable of engaging any sort of target, thanks to their weaponry. Destroyers were outfitted with multiple Stinger rocket launchers on their bows, which launched medium-range heat-seeking warheads capable of damaging aircraft, structures, or vehicles. While not as long ranged or effective against surface targets as the Cruiser's batteries, the missile's versatility and accuracy made them capable of limited bombardment. Destroyers were also equipped with sonar equipment and depth charges to attack submarines. The launchers on the Destroyer could launch more depth charges than the Gunboats, allowing them to severely damage enemy subs rapidly.

GWWIII
The Destroyer was substantially redesigned prior to the Great World War III, limiting its role somewhat. Instead of depth charge launchers mounted on the ship, these new Destroyers sported a helipad for launching the Osprey, a VTOL aircraft armed with torpedos designed to hit submarines and Giant Squids. Replacing the stinger launchers, the Destroyers had deck guns, capable of taking out minor ground targets and other surface ships. However, without the missiles, it lost it's anti-aircraft capabilities making it reliant on an Aegis Cruiser escort to defend it from airborne threats.

The use of Osprey VTOLs as a means of anti-submarine warfare could also be considered a weakness compared to the earlier class of Destroyers. Against enemy Sea Scorpion-class ships, Ospreys were helpless and easily destroyed; which meant that Destroyers were only reliable against submarines or squids when no AA was present.

WWIII:Assault Destroyer
A new class of destroyer by Gerhardt-Giraud Shipworks, the Assault Destroyer is one of the most powerful direct combat elements in the Allied Navy. Fully amphibious, it is capable of traversing land and sea with equal speed and mobility; and its armour and weapon vastly surpasses any tank currently fielded by the Allies.

While extremely slow and cumbersome on land like a slow heavy tank, the Assault Destroyer is capable of simply driving over lesser units, and its sheer power rivals even that of the Soviet Apocalypse.

Allied planners have noted its survivability; and have chosen the Assault Destroyer as a mount for Blackhole Armour. This is a powerful defensive system that causes all incoming enemy fire to hit the destroyer, whose own durability is increased while the armour is active. This safeguards less durable units from enemy attacks. Its highly accurate and powerful Reugart-GX cannon can even strike at submerged Akulas.
