The Hawaii-California Training and Testing Study Area consists primarily of the Hawaii Operating Area and Temporary Operating Area, the California Operating Area, and the transit corridor connecting the two.

The Study Area plays a vital role in meeting the naval readiness mandate. It has unique attributes, including its location, proximity to nearby installations, environment, infrastructure, and size, that make it an ideal setting for training military personnel and testing equipment and systems. 

Service member retention is also key to our nations readiness. Training and testing in areas close to a Sailor's homeport or an aviator's home base minimizes time away from their home and families.
