Located in the heart of the Pacific Northwest’s Puget Sound region, Joint Base Lewis-McChord is the Defense Department’s premier military installation on the West Coast. Joint Base Lewis-McCord is a training and mobilization center for all services and is the only Army power-projection platform west of the Rockies. Its key geographic loca- tion provides rapid access to the deep-water ports of Tacoma, Olympia and Seattle for deploying equipment. Units can be deployed from McChord Field, and individuals and small groups can also use nearby Sea-Tac Airport.
The strategic location of the base provides Air Force units with the ability to conduct combat and humanitarian airlifts to any location in the world with the C-17A Globemaster III, the newest, most flexible cargo aircraft in the airlift force.
