Which facility is noted for sustainment (depot) level maintenance?

The Corpus Christi Army Depot (CCAD) is specifically recognized for sustainment level maintenance, which involves comprehensive overhaul and maintenance of aircraft and their components. This level of maintenance is typically performed at depot facilities, where specialized equipment and skilled personnel work on complex systems that require extensive repairs, upgrades, and modifications.

CCAD plays a crucial role in the lifecycle management of military aviation assets, handling tasks that go beyond the capabilities of lower-level maintenance facilities. Such tasks include major repairs and upgrades to helicopters and their parts, ensuring they meet operational readiness standards.

In contrast, the other facilities listed do not primarily focus on sustainment level maintenance. For instance, Fort Hood Army Depot and Rock Island Arsenal have different missions that may include logistics and supply chain operations or military equipment maintenance, but they are not specifically known for sustainment level maintenance of aircraft. Joint Base Andrews is primarily an air base utilized for various military aviation operations rather than a dedicated maintenance facility.
