DAMEN introduced the new "Compact SIGMA" line of corvettes during DSEI 2013
DAMEN Schelde Naval Shipbuilding introduced the new "Compact SIGMA" line during DSEI 2013, the International Defence & Security event in London, United Kingdom. Undoubtedly, one of the major advantages of the Compact SIGMA (Ship Integrated Geometrical Modularity Approach) Series is that all of the good things from a large ship have been recreated in a smaller version, with ship sizes ranging from 600 tonnes to 1500 tonnes displacement and a length over all from 59 m to 87 m.

This smaller size ship can have the same combat systems and capabilities, but with a shorter range and a mission endurance of up to two weeks. Smart design and engineering lead to even higher reliability and availability.

The SIGMA modularity allows potentional customers to select the vessel size, sensor suite and weapons fit that perfectly match their needs,

A modular SIGMA corvette model was on display on DAMEN's stand at DSEI 2013.
In this configuration it shows an Integrated Mast Module, 8x anti-ship missiles, a 76mm main gun, a special mission container at the stern and two RAM launchers.

Advantages of the Compact SIGMA:
» Flexibility from standard commercial up to full implementation of naval platform features, depending on functionality
» High speed, swift manoeuvring
» Smaller size platform, 25% to 30% less power needed and less operational, maintenance and ILS costs
» Lower acquisition cost
» Reduced manning
» Ease of maintenance and docking
» Less complexity compared to large ship
» Ease of handling in confined waters and in ports
» High availability by smart engineering of platform propulsion and auxiliary systems
» Platform systems and components designed for quality working and cost-effectiveness and choice of selection

The new Sigma 9814, future corvette design of the Vietnamese Navy


Picture source: Quôc Phòng Viêt Nam
Based on previously published information and from what can be seen on the model shown at Vietship 2014 the new SIGMA 9814 class will be fitted with:
8x MBDA Exocet MM40 Block 3
12x MBDA MICA VL surface-to-air missiles (in VLS)
1x Oto Melara 76mm main gun
2x Oto Melara MARLIN-WS 30mm gun mounts
The corvette will acomodate one anti-submarine helicopters Ka-28. The corvettes are set to receive the latest generation of electronics and sensors from Thales including TACTICOS combat management system, SMART-S Mk 2 radar and STING EO Mk 2 electro-optical fire control system.

Design wise, the new Sigma 9814 differs quite a lot combared to existing Sigma designs (9813, 10513 or 10514) especially around the bridge area. Likewise, the bow appears to be more angled to possibly provide more stealth.
