Overview
USS Barbican (ACM-5) was a Chimo-class minelayer in the United States Navy. Barbican was later commissioned in U.S. Coast Guard as USCGC Ivy (WLB / WAGL-329). Barbican was constructed as the Army Mine planter USAMP Col. George Armistead (MP-3) by the Marietta Manufacturing Co. at Point Pleasant, West Virginia and delivered to the U.S. Army in December 1942. The ship was acquired by the U.S. Navy from the Army Coast Artillery at Charleston, South Carolina, on 6 January 1945; renamed Barbican and designated an auxiliary minelayer, ACM-5, on 19 January 1945; converted for naval service by the Charleston Navy Yard; and placed in commission there on 24 March 1945.
Composite Risk
Multiple adverse factors, or a hard ship-specific signal, lift this hull above the fleet norm.
A coverage-weighted blend of the single component we could read for this hull; the weights renormalise over only the components present, so a thin read is never inflated and a hull is never credited a “safe 0” for a signal it has no row for. This headline is flagged low-confidence (a thin or structural-only read) and should not be treated as a verdict. Higher means riskier. Derived in-house from government-open port-State-control, flag, sanctions and our own vessel data; weight it by the coverage above.
Commercial
