USS Warrior (MCM-10) is an Avenger-class mine countermeasures ship of the United States Navy. The Avenger-class ships were designed to have very low acoustic and magnetic signatures to avoid detonating mines. While most modern warships have steel hulls, the Avengers have wooden hulls with an external coating of fiberglass. They are equipped with sophisticated minehunting and classification sonar as well as remotely-operated mine neutralization and disposal systems.
