Ukushima
On the morning of November 11, the 54 meter long, wooden hull Japanese Maritime Self-Defense Force (MSDF) minesweeper Ukushima (MMSI: 31999662) was lost in Sagami Bay some 2.5 kilometers off Oshima Island, Japan. While conducting a drill, a fire started in the Ukushima engine room. The initial attempt by the crew to contain the blaze failed. As the fire began to engulf the vessel, the crew requested assistance. The Japan Coast Guard dispatch a fire fighting vessel while the MSDF redirected the minesweeper Toyoshima to the scene. After several hours of fire fighting, the fire looked as if it was contained. However, the fire would later flare up again a short time later and spread through out the wooden hull.
Authorities determined the next action was to evacuate the Ukushima crew over to the Toyoshima. When the evacuation was completed, a roll call found that the petty officer on duty in the engine room had been left on board the Ukushima.
Reports state the fire continued to engulf the Ukushima until the vessel capsized and sank. The Coast Guard have dispatched divers to inspect the wreck and search the vessel for the missing person. Authorities also state one other crew person was injured from smoke inhalation. This crew person was also on duty in the engine room at the time of the incident. The MSDF has launched an investigation into the incident.
Authorities have stated only one other minesweeper has been lost to a fire since 1966.
