Australia officially transferred former Adelaide-class frigates Melbourne (FFG 05) and Newcastle (FFG 06) to the Chilean Navy (Armada de Chile). A commissioning ceremony took place on April 15, 2020 at the HMAS Watson naval base in Sydney.

Following an extensive worldwide competitive tender, Lockheed Martin Canada was selected in 2017 to be the combat systems integrator for the Chilean Navy's three Type 23 frigates, leveraging its Canadian-developed combat management system, CMS 330.
