BAE Systems selects Sagem’s Sigma 30 inertial reference unit for Archer artillery systems to be deployed by Norway and Sweden

Paris, February 4, 2011

Sagem (Safran group) has won a BAE Systems contract, against an international field of competitors, to provide Sigma 30 pointing and navigation units for 48 new FH77 L52 Archer(*) artillery systems to be deployed by the Norwegian and Swedish armies. Service entry is slated for late 2011 with the Nordic Battalion.

Based on digital laser digital gyro technology, Sagem's Sigma 30 is the basis of a very-high-performance land navigation and artillery pointing system, designed to operate even under the most demanding conditions.

The Sigma 30 inertial units will be mounted directly on the 155 mm barrel. Because of their precision measurements, these units further enhance the high-level automation of the Archer artillery system, which is designed to lay down very accurate fire on short notice and at a high rate. Integrated in the artillery command and coordination systems, Sigma 30 will also enable Archer a wide range of firing options, in particular simultaneous strikes against a single target.

Sagem's Sigma 30 inertial reference unit equips some of today's leading artillery systems, including Caesar 155 mm truck-mounted howitzer, MLRS multiple launch rocket systems deployed by NATO countries, and the 2R2M 120 mm mobile mortar.

Sagem's artillery solutions, already deployed by armies in more than 20 countries, cover all designation and pointing requirements, including forward observation systems, networked optronic sensors, navigation and pointing systems, fire control, computers and digital mapping.

(*)Developed by BAE Systems, Archer is a self-propelled, fully automated, latest-generation artillery system. Equipped with a 155 mm / 52 caliber gun, Archer is capable of high rates of fire, with three-shot salvos in 13 seconds, to a range of 40 km.
