The U.S. Army might increase the number of these vehicles from 312 to 361.
The Army has approved the deployment of 162 Sergeant Stout systems to support the training and equipping of four battalions, with three units already equipped. According to Brig. Gen. Frank Lozano, program executive officer for missiles and space, the number of systems could increase from 312 to 361 to equip four National Guard battalions.
The Sergeant Stout system, based on the Stryker A1 vehicle, is designed to counter various aerial threats, including unmanned aerial systems and rotary- and fixed-wing aircraft. General Dynamics Land Systems leads the integration, incorporating the mission equipment package from Leonardo DRS, the Reconfigurable Integrated-weapons Platform (RIwP) turret from Moog, and the multi-mission hemispheric radar from Rada USA.
The initial RIwP configuration includes a modified M299 launcher for two Longbow Hellfire missiles, a Raytheon Stinger Vehicle Universal Launcher (SVUL) for four surface-to-air missiles, the Northrop Grumman 30mm Bushmaster XM914 cannon, and a 7.62mm M240 machine gun. This configuration is subject to updates based on soldier feedback and emerging threats, particularly from conflicts in Ukraine and the Middle East.
