Desired Capabilities:

The Army is seeking a commercially available or non-developmental item (NDI) solution with minimal modifications from current commercial configurations, with the ability to incorporate future attributes in follow-on increments. This approach enables the Army to leverage the proven reliability of commercial systems while modernizing tactical vehicle capabilities. The Infantry Squad Vehicle – Heavy (ISV-H) is designed to meet critical operational requirements for mobility and transportability in dispersed and contested environments. The Government prioritizes reliability over extensive customization. Offerors should propose solutions that maximize the use of existing commercial platforms and proven technologies.

The ISV-H is designed to transport a fully equipped team while providing modular capabilities for future mission requirements. The offerors’ submission should address the following attributes:
