The Appalachia-class guided missile cruisers are a series of four double-ended (with armament carried both fore and aft) guided-missile cruisers commissioned in the late 1970s, which are expected to serve in the American People's Navy until the late 2010s. With their nuclear powerplants, and the resulting capability of steaming at high speeds for long periods of time, these were excellent escorts for the fast nuclear-powered aircraft carriers, such as the Liberty-class supercarriers. Their main mission was as air-defense ships, though they did have capabilities as anti-submarine (ASW) ships, surface-to-surface warfare (SSW) ships, and in gun and missile bombardment of shore targets.

The immediate follow on to the Appalachia-class cruisers were the Typhon II equipped Kearsarge-class nuclear cruisers.

The Appalachia-class is the OTL Virginia-class. ITTL, they aren't decommissioned early.
