The Chilean frigate Almirante Cochrane, formerly known as HMS Norfolk, is a notable vessel originally built as a British Type 23 frigate. Laid down in 1985 by Yarrow Shipbuilders and launched in July 1987, she was commissioned into the Royal Navy on 1 June 1990. As the first of her class, she represented a new generation of "lean manned" ships, emphasizing efficiency and modern design. The vessel measures approximately 133 meters in length and was equipped with advanced weaponry and sensors for her time, including being the first in her class to carry the Vertical Launch Seawolf missile system and the new 4.5-inch Mod 1 gun system. Throughout her service, HMS Norfolk participated in numerous deployments and exercises worldwide. In 1992, she was part of the Orient 92 Task Group, visiting the Eastern Mediterranean, Mauritius, Diego Garcia, Malaysia, Thailand, South Korea, Hong Kong, and Oman. She also conducted first-of-class shock trials in Portsmouth and became the first Type 23 to host Wren ratings at sea in 1993. Notably, in 1994, she was the first Royal Navy warship to visit South Africa in over two decades, symbolizing improved international relations post-apartheid. Her operational history includes a deployment to Sierra Leone in 2000 to assist in peace restoration, a visit to the United States, and participation in NATO exercises. She also served as guardship for the Falkland Islands and operated in the Caribbean and the Persian Gulf. An interesting anecdote from her service involved a bottlenose dolphin, named Norfolk, encountered during exercises in 2000. Decommissioned from the Royal Navy in 2005, she was sold to the Chilean Navy and commissioned as Almirante Cochrane in November 2006, honoring the Chilean naval hero Thomas Cochrane. From 2018 to 2019, she underwent a significant upgrade, which included the installation of the CMS 330 combat management system, TRS-4D G-band radars, and 32 CAMM Sea Ceptor vertical-launch missile silos, enhancing her surface-to-air missile capability. Her conversion underscores her ongoing maritime significance and adaptability in modern naval operations.
