There have been eight ships in the British Navy to bear the name. Defender means to keep safe from danger, attack, or harm. To defend implies repelling an attack. Thus, the motto of the U.S. Defender is “Secure the Course!” The hound on the ship crest emphasizes the search and protect roles of the USS Defender in clearing the seaways for safe passage of the sea lanes and littorals.
USS Defender (MCM-2) is the second Avenger-class mine countermeasures ship in the U.S. Navy. The Defender was laid down on 1 December 1983 at Marinette Marine Corp., Marinette, Wisconsin; launched on 4 April 1987; and commissioned on 30 September 1989. The USS Defender has participated in many operations, training exercises, roles and missions in her tenure in the U.S. Navy. Currently forward deployed in Sasebo, Japan, Defender is ready to keep the sea lanes in the Pacific theater safe from danger, attack and harm.
