Fleet Solid Support (FSS)

The Royal Fleet Auxiliary’s Fleet Solid Support (FSS) ships are essential to sustaining the UK Royal Navy’s Carrier Strike Group at sea. These vessels are designed to deliver vital munitions, supplies, and provisions during operations — enabling extended deployments without returning to port.

Led by prime contractor Navantia UK, BMT Engineers and naval architects developed an advanced design for three 216m FSS
ships, enhancing the Royal Navy’s operational capability and logistical support and contributing to the Royal Navy’s Net Zero 2050 goals.
