It is true that the US and any major military is constantly updating her weapons systems. However, given the current political climate, it is curious that such weapons are being produced at this time:
The U.S. Army roughly awarded a roughly $205,2 million order to Raytheon Co. Missile Systems for Phalanx Gatling guns.
According to a statement, announced Friday by the U.S. Department of Defense, Raytheon Missile Systems has been awarded a $205,2 million U.S. Army contract for the counter-rocket artillery mortar weapon system, called the Phalanx.
Work locations and funding will be determined with each order, with an estimated completion date of Dec. 27, 2023.
A Phalanx Gatling gun, most often used by naval ships to defend against incoming missiles and rockets, is a self-contained counter-rocket artillery mortar weapon system.
According to Raytheon, the Phalanx weapon system automatically carries out functions usually performed by multiple systems: search, detection, threat evaluation, tracking, engagement and kill assessment.
Phalanx can be interfaced with a multitude of sensors and systems designed to provide an overarching protection umbrella of sites on the ground.
Phalanx uses six optimized gun barrels along with an integrated forward-looking infrared (FLIR) sensor suite. More stringent firing schedules are provided for by securing the six barrels at the muzzle, mid-barrel and breech, for more accuracy and a concentrated shot dispersion pattern. (source, source)
