Our 4.5 inch naval ammunition is designed for use with the 4.5 inch Mk8 naval gun. They are fixed rounds and comprise of a shell, fuze and propelling charge.

When the Royal Navy needed a replacement for its current in-service illuminating round, BAE Systems developed an amended shell body design that suits the new fuze, a new driving band and base ejection geometry with an updated payload. The round is available as visible and infrared.

In addition to the new illuminating rounds, BAE Systems continues to manufacture High Explosive Improved Ammunition (IA) and Surface Use Practice (SUP) IA rounds.
