151 cracks found on the propellers of ROKN submarine An Jung-geun

National Assembly member Kim Kwang-jin stated that ROKN HQ reports from August 2014 revealed that there were 151 cracks on the propellers of the ROKN submarine An Jung-geun. Seven cracks were originally found during inspection and thorough examination by the manufacturer found 151 cracks. The manufacturer, Hyundai Heavy Industries, stated to DTaQ that four propellers had substantial cracks and thus could not be used, but DTaQ notified ROKN that the propellers were manufactured according to requested specifications and thus had no problems. The manufacturer eventually replaced the propellers as after-service.
