The Stryker ESV is based on the Stryker ICV, and is modified to better mount and carry engineer equipment. On the lower front hull, the Jettison Fitting Kit (JFK) is mounted to allow attachment of various mine rollers, mine plows, and obstacle blades. Control over the attachments is provided by the Mission Equipment Control Unit (MECU) mounted in the driver's position, and the vehicle's headlights are moved to the end of extensions to clear the attachments. On each side of the hull rear can be mounted a Lane Marking System (LMS) that shoots marker poles into the ground with 100psi (7kg/cm²) of air pressure. Each of the dispenser units can hold 50 poles, and the control box for the LMS is situated to the right of the squad leader's position. The ESV has a rack above the rear ramp for a stowage box which, along with two stowage boxes along the hull sides, provides space for engineering supplies and equipment such as charges, fuses, detonator cord, blasting caps, etc.
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.
