Having visited JMSDF helicopter mines sweeping squadron in the 1980s, the KHI Vertol 107s were the current airborn minesweeping assets of the time. They were being replaced by a fleet of Sikorsky S-80M-1 (MH-53Es) at that time The 107s were sold world wide. I later saw one was part of a Swedish navy fleet. They were relatively low flight time machines as the JMSDF retired their aircraft after 5000 hours as part of the JMSDF policy. They were also meticulously maintained.
