The SIGMA class is a Dutch-built family of modular naval vessels, of either corvette or frigate size, designed by Damen Group.
SIGMA stands for Ship Integrated Geometrical Modularity Approach.[4] The basic design of the SIGMA Patrol Series can vary as the hull segments are designed as components. Ships can vary in the number of hull segments and in the order in which they are placed. The ship's dimensions of length and beam lead to the individual SIGMA type names: the SIGMA 9113 is 91 m (298 ft 7 in) long with a beam of 13 m (42 ft 8 in), the SIGMA 10513 is 105 m (344 ft 6 in) in length again with a beam of 13 m (42 ft 8 in)
The design was derived from the earlier High Speed Displacement hull form by Marin Teknikk AS in the 1970s.[citation needed]
