The Stryker FSV is based on the Stryker ICV and is externally almost identical to the Stryker RV. The Stryker FSV features the power-assisted commander's cupola which is usually armed with the .50cal MG. Also attached to the cupola were the AN/TAS-4 and AN/TVQ-2 Ground/Vehicle Laser Locator Designator (G/VLLD), but these were replaced in production with the Fire Support Sensor System Mission Equipment Package with its own Laser Designator Module. Both systems are equipped with both daylight and forward-looking infrared (FLIR) sensors and allow the Stryker FSV to provide laser and GPS designation to various homing ordnance. The FS3 can be dismounted from the vehicle by using a manual crane that is stowed on the roof behind the commander's station.

The hull bottom was modified into a double-V shape beginning in 2010 in order to help mitigate the blast effect of mines and improvised explosive devices. The double-V hull (DVH) improvements also featured enhancements to the suspension system, wider tires, a height management system, and blast-resistant seating for the infantry squad. Further upgrades--including a 450hp engine; 60,000lb (27,000kg) suspension; 910-amp alternator; and an in-vehicle network--produced the Stryker A1 variant.
