September 10, 2005 Mine warfare ships USS Defender (MCM 2), USS Gladiator, USS Scout (MCM 8), and USS Falcon (MHC 59) are currently working off the coast of Louisiana with the U.S. Coast Guard, U.S. Army Corps of Engineers and National Oceanic and Atmospheric Administration, helping to clear waterways that may be clogged by debris. The ships are identifying obstructions so that U.S. Navy and Coast Guard divers can recover them to ensure safe passage.

September 29, Mine warfare ships based in Ingleside, Texas, are prepared to deploy in support of Hurricane Rita disaster recovery efforts. MCM 1, MCM 11 and MCM 9 are conducting unit level training and sonar calibration operations in the Gulf of Mexico. These ships are on standby to conduct survey operations of the Galveston and Houston safety fairways to help determine if they are free of any storm-related debris and to ensure the safety of deep-draft traffic transit.

December 7, 2006 USS Gladiator departed from Naval Station Ingleside, Texas, after being loaded aboard Military Sealift Command (MSC)-chartered heavy lift ship Condock V (6763/84). MSC chartered the ship in September after receiving a request to transport the Gladiator from Texas to Bahrain. Moving the mine countermeasures ship in this manner prevents the wear and tear of an open-ocean voyage. MCM 11 will replace one of two coastal mine hunters (MHC) being decommissioned and sold to Egypt. A second mine countermeasures ship will be transferred via heavy-lift on another Condock ship later this year.
