The Canonicus (ACM-12) was a concrete-hulled ship that served as a mobile training platform during World War II. Commissioned in 1944, the Canonicus was used to train crews in anti-submarine warfare tactics and techniques. The ship was equipped with various weapons and sonar systems to simulate real combat situations for training purposes. After the war, the Canonicus was decommissioned in 1946 and placed in the reserve fleet. In 1950, the ship was reactivated for the Korean War and used as a training vessel until 1958. The Canonicus was eventually sold for scrap in 1970, marking the end of its service. The ship's unique concrete hull design was experimental and aimed to address steel shortages during the war. Despite its short service life, the Canonicus played a significant role in training naval personnel during a crucial period in U.S. military history.
