Sagem's SIGMA 40 navigation system chosen by Norwegian navy for offshore patrol boats

Sagem (Safran) has won a competitive tender issued by the Royal Norwegian Navy to modernize the navigation system on its three Nordkapp class offshore patrol vessels. These armed, helicopter-carrier patrol boats displace more than 3,300 metric tons, and will be fitted with Sagem's SIGMA 40 laser gyro navigation systems. 

Developed and produced by Sagem, the SIGMA 40 is a laser-gyro inertial system designed to guarantee high-precision navigation even in the harshest environments. A completely standalone unit, the SIGMA 40 contributes to the effectiveness of shipborne systems and also to the success of even the most demanding missions assigned to warships. 

The Royal Norwegian Navy chose Sagem's SIGMA 40 system because of its excellent sustained performance under the country's specific maritime conditions: fjords, inclement weather, ice, etc. Another decisive factor in its selection was the Sigma 40's long-term resistance to shocks. The SIGMA 40 is in fact one of the few shipborne navigation systems that comply with shock resistance specifications in the military standard MIL-S 901 D.

This latest contract further consolidates Sagem's 20-year partnership on navigation systems with the Royal Norwegian Navy, also underpinned by consulting services provided to the navy. Sagem's SIGMA 40 XP system was also selected by the Norwegian navy for the modernization of six ULA class submarines, starting in 2008. 

The SIGMA 40 navigation system is now used on more than 500 surface naval vessels and 75 submarines, especially the latest and most innovative front-line ships, such as the European FREMM and Horizon frigates, the Mistral class amphibious assault ship and the Korean LPX Dokdo amphibious helicopter-carrier. The SIGMA 40XP version of the system was chosen for the conventional Scorpène class submarines built by French naval shipyard DCNS, the modernization of the navigation systems on the Amethyst class nuclear attack submarines, and the upcoming Barracuda class submarines.
