Over its passenger compartment, the Stryker ATGM mounted an Elevated TOW System (ETS) twin-tube launcher that was compatible with all TOW missile variants. The ETS mast raised 0.5m (20") above the hull roof to help enable the vehicle to make use of hull down positions. The 1,400kg (3,100lb) ETS incorporated a CCD television daylight sight as well as a second-generation FLIR night sight. The ETS also had four M6 smoke grenade launchers mounted on its right side. Ten missiles were stowed in the vehicle in addition to the 2 in the launcher: a rack to the loader's left held three missiles, a rack to his right stowed six, and a floor rack contained a single missile. Reloading was accomplished through a hatch on the rear hull roof by elevating the ETS to +40°, and could be completed in under 2 minutes. The commander's MG needed to be folded down before the missile launcher was fired. The M1134 served in mobile gun system platoons until the Stryker MGS could be fielded.
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.
