U.S. Navy 5″/54 caliber artillery projectile, AMS 90 F shell fitted with a W.R.C. Mk 4 Mod 0 shell cap

This is an original U.S. Navy 5″/54 caliber artillery projectile, identified as an AMS 90 F shell, fitted with a W.R.C. Mk 4 Mod 0 shell cap. Projectiles of this type were developed for high-velocity naval guns intended for advanced anti-aircraft and surface engagement roles, reflecting the continued evolution of U.S. naval ordnance during and immediately following the Second World War.

The 5″/54 caliber configuration offered a longer barrel and higher muzzle velocity than the more common 5″/38 system, providing improved range, flatter trajectory, and enhanced effectiveness against fast, high-altitude aircraft. Shells of the Mark 90 family were engineered to meet these demanding performance requirements, incorporating refined ballistic profiles and specialized caps to improve flight characteristics and fuze compatibility.

The W.R.C. Mk 4 Mod 0 shell cap represents an early standardized cap design, intended to protect the projectile nose during handling and firing while optimizing aerodynamic efficiency. Such caps were critical components in naval ammunition design, contributing directly to accuracy, consistency, and operational reliability under combat conditions.

Manufactured to strict U.S. Navy specifications, this projectile exemplifies the industrial precision and scale of American naval weapons production in the mid-20th century. Examples of 5″/54 ammunition are notably less common than 5″/38 rounds, as fewer ships were equipped with the longer-barreled guns and production runs were more limited.

This shell is an excellent reference and display piece, suitable for advanced naval ordnance collections, museum exhibits, or educational settings focused on U.S. Navy gunnery, anti-aircraft warfare, and the technological progression of naval artillery.
