Almost identical to the Alta class, the only differences are the equipment on the aft deck and aft 1. deck, the sonars (two instead of one), and the length of the superstructure on 1. deck. The minehunters carry two ROV's, and when in active service a few highly trained divers, with competence in mine clearing. While the minesweepers have only one rigid inflatable boat, the Oksøy-class carries two, one for the divers and one for other purposes.
