Proposed Action
The Proposed Action is to conduct at-sea military readiness activities, comprised of training, testing, and modernizing and sustaining 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 modernization of underwater ranges in Southern California
- Sustainment of undersea ranges throughout the Study Area
- Deployment of seafloor cables and connected instrumentation in Southern California and Hawaii
- Installation and maintenance of mine warfare and other training areas offshore of Hawaii and Southern California
- Installation and maintenance of underwater platforms in Hawaii and Southern California
The purpose of the Proposed Action is 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.
