The multipurpose and fast Jehu class represents the newest capacity of the Navy. The ships can be used for troop transports, medical and evacuation tasks, landing, sea surveillance and escorting tasks, as well as for battle and battle support missions. The Jehu boats can be used both in the archipelago and coastal areas and on the high seas.

The Jehu class strengthens the capacity of the coastal troops of the Navy. The capacity of the Navy’s warships is good at the moment, but during the next decade a remarkable part of the warship fleet will have to be replaced by new capacities.

Finland has ordered 12 of these fast, maneuverable vessels

Combat Support Service Vessel (CSSV)

The latest vessel developed by Marine Alutech is the Watercat M18 Armored Modular Craft (AMC). This is a new landing craft, which is designed to fulfill all modern requirements for future combat support vessels. It has been recently announced that Marine Alutech will deliver 12 pcs of these Watercat M18 AMC multipurpose high-speed landing crafts to Finnish Navy during 2014-2016. The vessels will be powered by two 660 kW Scania diesel engines and feature Rolls-Royce waterjet propulsion.

The Watercat M18 AMC is suitable for troop transportation, medical and evacuation tasks, landing operations, patrolling and escort tasks, as well as combat and battle support scenarios. The vessel has been specially designed for archipelagic, coastal and offshore conditions with an effective heating and air-conditioning system allowing heat and extreme cold, arid or humid climates.

The Navy secures the territorial integrity of Finland day and night, every day, by keeping at least one warship in constant readiness
