Weapon systems employ directional mountings or directors for most of its tasks, to point and follow sensors or weapons towards the target.

Modern electrical motors provide precision, reliability and reduction of maintenance that are reflected in several advantages for these roles.

In those cases where a mounting has hydraulic propulsion, its transformation to electrical traction propagates these advantages to legacy units. DESA has developed these modernization projects in this area which have proven its effectiveness and performance.

Modernization of servosystems may include change to electrical traction as well as an upgrade of control systems, ranging from servoamplifiers, positioning sensors, architecture integration to weapon systems and improvement in failure detection.

Similar upgrades have been applied to several systems like Oto-Melara and Bofors guns, radar antenna pedestals like ELTA EL/M-2221 and optical sights.
