FGM-148 Javelin system to receive electro-optical guidance system
Raytheon Technologies has signed a contract to supply 4,000 units of electro-optical guidance systems for the Javelin ATGM. The customer was the Defense Cooperation Agency, which operates under the US Department of Defense. The guidance systems for anti-tank missiles are intended for the United States and its allies.
At the moment, Javelin missiles are being guided to the target using thermal homing. Simply put, the missile identifies the target by its thermal radiation. According to experts, this method of guidance has a number of drawbacks. In particular, terrain, clouds, or even smoke can interfere with the missile’s accurate targeting.
The electro-optical guidance system consists of two main elements: a sight and a guidance unit. Target detection and acquisition is performed by the operator using the sight mounted on the launcher. The guidance unit is located in the head part of the anti-tank missile. After launching, it is able to track the target designated by the operator independently. Compatibility between the sight and the guidance unit is ensured by the same electro-optical sensors.
In contrast to the thermal guidance system, the electro-optical guidance system uses a laser rangefinder and visible light in addition to the thermal image. It helps the missile better distinguish the target from the background. The cost of producing a missile with an electro-optical guidance system is lower than with a thermal one. At the same time, it has a longer service life.
