Overview
Isuzu (五十鈴) was the second of six vessels in the Nagara class of light cruisers, and like other vessels of her class, she was intended for use as the flagship of a destroyer flotilla. She was named after the Isuzu River, near Ise Shrine in the Chūbu region of Japan. She saw action during World War II in the Battle of Hong Kong and in the Solomon Islands campaign, and the Battle of Leyte Gulf before being sunk by American submarines in the Netherlands East Indies in April 1945.
Live Tracking
Most time stopped at Wakayama-Shimotsu Ko — 5 d across 3 stays.
Derived from the AIS track — runs of near-zero speed (anchored, moored or drifting) snapped to the nearest port. Builds up as we observe the vessel.
Intelligence
AIS-derived from our live feed.
Operational Status
Stopped, anchored or moored on its latest broadcast — parked, not necessarily withdrawn.
Read from the single most-recent AIS broadcast we hold for this hull — we keep no position history, so this is a point-in-time posture, not a dwell inference. Derived in-house from our own AIS feed; weight it by the broadcast age above.
Composite Risk
Multiple adverse factors, or a hard ship-specific signal, lift this hull above the fleet norm.
A coverage-weighted blend of the 2 components 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.
Estimated
Other · summer draught 9.9 m · 30.8 t per cm immersion
Estimate only — modelled from deadweight (hull geometry) using a first-principles hydrostatic model, not measured hydrostatic tables. The design draught it is anchored to is unreliable across the fleet.
