The Proposed Action is to conduct at-sea military readiness activities, comprised of training, testing, and modernization and sustainment of ranges, in the HCTT Study Area.
- Train and test at sea to support Primary Mission Areas:
- Air warfare
- Amphibious warfare
- Anti-submarine warfare
- Electronic warfare
- Expeditionary warfare
- Mine warfare
- Surface warfare
- Modernize and sustain ranges:
- New special use airspace in Southern California
- Installation and maintenance of underwater ranges in Southern California and Hawaii

The purpose of the Proposed Action is to conduct at-sea military readiness activities in the HCTT Study Area to ensure U.S. military services are able to organize, train, and equip service members and personnel to meet their respective national defense missions.
Proposed activities are similar to those analyzed in previous at-sea environmental analyses and are consistent with activities conducted off Hawaii and California for more than 80 years.
