The Fer-de-lance-class destroyer escort consists of four blocks. In the bow block, a control bridge and living compartments are arranged. Behind it is a central hull block with cargo hold, a hangar, a jump drive and fuel tanks. On both sides, there are drive blocks with maneuver drives and powerplants installed. Six laser turrets are arranged to concentrate firepower in the bow direction. After Block III, an armored hull was adopted, and the bow block was changed from a spherical shape to a more constructable polygonal shape.
