Aloha and welcome to the United States (U.S.) Navy’s Medium Landing Ship (LSM) Homeporting in Hawaiʻi environmental planning website.
This website is a resource for information on the preparation of the LSM Homeporting Environmental Impact Statement (EIS). The U.S. Department of the Navy is preparing an EIS to assess the potential environmental effects associated with the proposed homeporting of LSM-class ships at Joint Base Pearl Harbor-Hickam (JBPHH), Hawaiʻi. The LSM-class ship is a specialized vessel designed to transport troops, vehicles, and equipment directly to shore. The LSM-class ship, formerly known as Light Amphibious Warship, will be introduced in 2031. The Navy’s Proposed Action is to home port up to nine LSM-class ships at JBPHH, including the demolition of the existing wharf and construction of a dedicated berthing wharf along Ford Island and Roll-on/Roll-off facilities required to support the LSM-class ships. The U.S. Army Corps of Engineers has been invited to be a cooperating agency in the preparation of the EIS due to its
jurisdiction by law or special expertise concerning impacts on
waters of the United States.
Homeporting is the act of assigning a particular naval base or port as the location where a ship and its crew will primarily be based, maintained, and supported. Home ports provide a central location for ships to undergo routine maintenance, resupply, support training, and obtain administrative support when not deployed at sea. Home ports also serve as a staging area for deployments and a return point after completion of missions.
