Tusk was decommissioned at New London, Connecticut, struck from the Naval Vessel Register, and on 18 October 1973 transferred, by sale, to the Republic of China (Taiwan). Ex-Tusk'' was commissioned into the Republic of China Navy as Hai Pao (meaning "seal"), first with hull number SS-92, then SS-794, and finally SS-792. The terms of the purchase specified that she be used strictly for ASW training, so her torpedo tubes were welded shut before the transfer. The Taiwanese restored the torpedo tubes in 1976 and reportedly received modern torpedoes through Italy from a number of sources. The boat is reportedly allowed only to operate in sea shallower than 100m.
