The US Navy has taken delivery of USNS John L. Canley (ESB 6), an ESB-class ship designed for various military operations such as Airborne Mine Counter Measures, Special Operations Force operations, Crisis Response Sea-basing, Intelligence, Surveillance, and Reconnaissance, and Unmanned Aviation Systems operations. The ESB-class ships have a flight deck capable of supporting MH-53E helicopters, accommodations, workspaces, and ordnance storage for embarked forces, and enhanced command, control, communications, computers, and intelligence. The ship is part of the critical access infrastructure that supports the deployment of forces. The future USS Robert E. Simanek (ESB 7) is currently under construction at the General Dynamics NASSCO shipyard in San Diego.
