General Dynamics Land Systems was awarded last week $258 million contract modification to upgrade 116 Stryker flat-bottom vehicles to the Stryker A1 configuration. The upgrade includes the installation of Double-V Hull (DVH), improving the vehicle’s survivability against mines and improvised explosive devices (IED). In addition to the DVH survivability, the Stryker A1 provides a 450-horsepower engine, 60,000-pound suspension, 910-amp alternator and in-vehicle network. All vehicles will be delivered by March 31, 2020. The company already received several orders as part of an acquisition to equip the 4th Stryker Brigade with some 330 modernized vehicles by 2020.
