Input: Text:  The Australian Landing Craft 50 or ALC 50 was a class of Landing Craft Utility operated by the Australian Army. The two ALC 50s were built by Phoenix Shipyards in Devonport Tasmania and were probably completed in 1960. During their service with the Army they were named AB 3000 and AB 3001. The ALC 50s were replaced by Balikpapan class landing craft heavy in the early 1970s.
