The Proposed Action is to conduct training and testing activities at sea and to modernize and sustain at-sea ranges in the Study Area. At-sea military readiness activities were last analyzed in the 2018 Hawaii-Southern California Training and Testing EIS and the 2022 Point Mugu Sea Range EIS.
In addition to training and testing by the Navy and Marine Corps, the Proposed Action includes activities conducted by the Coast Guard, Army, and Air Force when those activities are similar to Navy and Marine Corps military readiness activities.
The Proposed Action also includes modernizing and sustaining at-sea ranges to support training and testing activities. Proposed actions include:
- New special use airspace in Southern California,
- Installation and maintenance of underwater ranges in Southern California and Hawaii,
- 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, and
- Installation and maintenance of underwater platforms in Hawaii and Southern California.
These actions are crucial for military readiness, personnel safety, and national defense.
