Maritime forces from the US, Australia, Japan, and the Republic of Korea have successfully concluded the annual quadrilateral maritime exercise, Pacific Vanguard (PACVAN) 2021.

The event, held in Australian waters, was designed to boost the interoperability of the navies and provide an opportunity to hone warfighting skills.

HMAS Brisbane commanding officer commander Aaron Cox said: “Exercise Pacific Vanguard builds on the strong and longstanding relationship between the Royal Australian and United States navies and reflects our shared commitment to robust navy-to-navy relationships across the region.

“Our fleet has enjoyed multiple chances to work with the United States Navy this year and the crew of Brisbane is eager to test their skills with USS Rafael Peralta and show how our capabilities combine.”

The exercise involved joint surface-to-air missile firing on the East Australian Exercise Area (EAXA).

In addition, the event included several training activities, such as surface warfare, anti-submarine warfare, and ship-to-ship communications.

The Royal Australian Navy Hobart-class destroyer, HMAS Brisbane, Japanese ship Takanami-class destroyer Makinami, South Korea’s Chungmugong Yi Sun-sin-class destroyer ROKS Wang Geon, and the US Navy’s Arleigh Burke-class guided-missile destroyer USS Rafael Peralta participated in the exercise.

Collins-class submarine HMAS Rankin (SSG 78) and aircraft from the Royal Australian Air Force (RAAF) also represented Australia in the exercise.

USS Rafael Peralta commanding officer commander JJ Murawski said: “Pacific Vanguard gives the US and its allies a venue for high-end training that will contribute to our ability to effectively work together to face current and future threats.

“Continuing to develop the bonds between each of our navies and our ability to operate together will help to ensure the stability of the Indo-Pacific region.”
