The depot and repair ship HMAS PLATYPUS, (CMDR E. C. Boyle, VC, RN), was commissioned. PLATYPUS, (ex-PENGUIN, ex-PLATYPUS), was laid down in John Brown Yard, at Clydebank, Scotland, on 14 October 1914, and launched on 28 October 1916. As both of the RAN’s submarines, (AE1 and AE2), were lost, PLATYPUS remained in service with the RN for the duration of WWI.
