Sigma-class Corvette

The Sigma-class corvette is a Dutch-built family of modular naval vessels, of corvette size. 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. Sigma stands for Ship Integrated Geometrical Modularity Approach. The ship's main dimensions are named in the types itself, SIGMA 9113 stands for 91 metres (298 ft 7 in) long and with a beam of 13 metres (42 ft 8 in). Likewise, the SIGMA 10513, is 105 metres (344 ft 6 in) in length with a beam of 13 meters.

The design was derived from the earlier High Speed Displacement hull form by MARIN Teknikk AS in the 1970s.
