On 17 May 1958 Aurochs was patrolling the Molucca Sea off Indonesia when an unidentified aircraft machine-gunned her. The aircraft remained at high altitude and Aurochs sustained no casualties or damage. President Sukarno's Indonesian government told the UK's Conservative Government that its armed forces had not made the attack. The UK Foreign and Commonwealth Office stated that it accepted the assurance and assumed that North Celebes rebels had carried out the attack.
