Operation Chronicle was the name given to the landing of Allied forces on Kiriwina and Woodlark Island on June 30, 1943, during World War II. Following the landing U.S. Army Engineers supervised construction of Kiriwina Airfield, including a 2,000 metre (6,000 ft) coral-surfaced runway.
A seaplane base was constructed at Losuia, consisting of an anchorage and jetty.
