USS Siren (PY-13), briefly CMc-1, was built by Pusey and Jones, Wilmington, Delaware and launched 15 November 1929 as the yacht Lotosland.

[note 2] The yacht's keel was laid 13 June 1929 as yard hull 408, contract 1043, and launched 15 November 1929.

[1][4] Lotosland was constructed of steel with clipper bow and transom stern with two pole masts and stack placed approximately amidships.

Above was an unusually large bridge deck housing in which there were two staterooms with private baths for the owner and his wife designed for use in tropical cruising.

The spaces were air conditioned by early devices called Room Coolers hidden behind decorative grill work.

[2] Siren was converted for military use at the General Engineering & Ship Works yards in Neponset, Mass.

This change was part of the Navy's response to the German submarine offensive of 1942 which was centered in the Caribbean Sea and the Gulf of Mexico.

During this and her next assignment-to the Commander, Atlantic Fleet-from December 1942 until April 1944, Siren patrolled and escorted convoys along the southeastern coast of the United States and between the islands of the Caribbean.

Siren was struck from the Navy list on 13 November 1945 and turned over to the War Shipping Administration for disposal.
