Welcome
Welcome to the United States (U.S.) Department of the Navy's Atlantic Fleet Training and Testing (AFTT) Environmental Planning Website.
The AFTT website is an online resource for information concerning the potential environmental effects of training and testing (military readiness) activities that occur in, over, and on the western Atlantic Ocean along the East Coast of North America, the Gulf of Mexico, and portions of the Caribbean Sea.
This fourth (Phase IV) comprehensive review supplements the previous 2018 Final AFTT EIS/OEIS and incorporates an updated acoustic effects analysis, updated marine mammal density data, and evolving and emergent best available science. It is anticipated that a Final AFTT Supplemental EIS/OEIS will be released in August 2025 to support renewal of current federal regulatory permits and authorizations that expire in November 2025.
