The vessels will be used by SMIT International to train military aircrew in marine survival techniques and to provide firing range safety services.

Delivery is to be within 16 months, a demanding schedule which will see construction split between Babcock BES' Rosyth dockyard and the FBMA Babcock Marine yard in the Philippines. Design and project management is being undertaken from FBM Babcock Marine's Southampton head office.

The vessels are an adaptation of FBM Babcock Marine's 27m patrol vessel, with accommodation and layout modifications to fulfil SMIT International's operational requirements. The design includes an aft docking well for a RIB or for torpedo recovery, a full width stern training platform and clear deck areas for helicopter winching drills. Additional removable equipment profiles will be supplied to allow the simulation of a variety of typical helicopter winching conditions.

Both hull and superstructure are of aluminium alloy construction.

An unusual propulsion arrangement sees two diesel engines driving propellers while a third, centre-line diesel, will power a waterjet. The addition of the waterjet allows the vessels to operate economically at slow speed for long periods of time and also provides enhanced manoeuvrability. Full power will take the Lloyds Register classed vessels to a top speed of 22 knots. Accommodation is provided for six crew.
