[en] The research group MRN04 has made a study of modernization of frigates of the Belgian Navy. The modernization includes fitting out of a landing area for an 11 tonnes helicopter, modifying the superstructure to solve the problems of cracks and reducing the radar cross section.

The proposal of the group MRN04 consists of widening and stiffness the stern deck in order to permit landing of a helicopter, surrounding the existing superstructure by a new envelop having a better furtivity.

The resistance of the helicopter landing area and the rigidity of the superstructure has been estimated by structural computations by finite elements method, which permits to choose the most adequate structure.

Once the weight of the new elements is known, a new estimation of the weight is established. It permits to calculate the draft and the trim, and serves as the data to calculate the ship resistance. In fact, the speed of the frigate, as a crucial point, should not decrease too much. The ship resistance will be obtained by means of model tests in the towing tank in the University of Liège.

The study shows the possibility to lay out a landing area for a helicopter of 11 tonnes as well as to decrease significantly the radar cross section, without severe reduction of the frigate speed.
