What does 'Sustainability' mean in the context of Army Acquisition?

In the context of Army Acquisition, 'Sustainability' refers to the ability of a system to be maintained and supported over its entire lifecycle. This includes not only physical maintenance and operational support but also considerations for logistics, training, and supply chain management to ensure that the system can continue to function effectively in diverse environments.

A system that is sustainable is designed with an understanding that it will need ongoing support. This encompasses ensuring that spare parts are available, personnel are trained to perform necessary repairs, and that the system can adapt to changes in technology or mission requirements over time. This concept is crucial because it directly impacts the long-term effectiveness and readiness of military capabilities.

While durability during deployment, cost-effectiveness, and environmental impact are important factors, they are more specific aspects of overall system performance or considerations that inform sustainability rather than defining it. Sustainability encompasses a broader spectrum of maintenance and support activities essential for keeping military systems operational over time.
