The article describes a new design for a trimaran escort frigate developed by the UK Ministry of Defence. Survivability and stealth offer significant advances in the trimaran. The cost is less than that of the monohull and its configuration allows a simplified propulsion and electric system. The underwater hull form has been developed from a Type 23 and includes bilge keels and stabilisers, the box length is the same as that of the side hulls, there is flare on all hull surfaces above the waterline including transom and box sides and the waterline separation of the hulls is 4.2m. Each hull has one propellers. Damage cases were run to show that stability after damage far exceeds the monohull requirement. The trimaran also offers the potential to repair damage more effectively.
