During the Yuyo Maru No.10 Incident [ja] that occurred on 9 November 1974, the 10th Yuyo Maru, which had fallen into difficulty extinguishing the fire, was dispatched together with JDS Haruna, JDS Takatsuki, JDS Mochizuki and JDS Yukikaze to sink the ship. After arriving at the disposal area on the afternoon of November 28, the submarine launched a salvo of torpedoes and fired four Mk37 torpedoes, but due to mechanical failures, misalignment, and lack of warhead power, the ship failed to sink.^[3]
