As the sole supplier of surface combatants to the Royal Netherlands Navy (RNLN), Damen Schelde Naval Shipbuilding has the experience of over 50 years of continuous combatant development. Seven generations of Frigates have been built up to now.

In order to fulfill the world markets demand of today and the next decades for reliable, multifunctional, high quality state of the art combat vessels with a short lead time and attractive price, a new concept has been developed. The result of this development is the Ship Integrated Geometric Modular Design Approach, called SIGMA.
