Royal IHC and Naval Group have signed their first contract under the Royal Netherlands Navy’s Orka-class submarine programme, covering the design and planned production and installation of onboard accommodation modules.
Signed on 15 September 2026, the agreement is part of the Replacement of the Netherlands Submarine Capability (RNSC) Programme, under which the Netherlands is replacing its existing submarine capability.
Royal IHC to design submarine living quarters
Under the initial contract, Royal IHC will contribute to the design of the living quarters for the new submarines. In a subsequent phase, the company is expected to undertake the production and installation of the accommodation quarters within the relevant modules.
