Marines with 3rd Marine Littoral Regiment will join ground forces along with a fleet of ships, submarines and aircraft from 26 countries for this year’s multinational, Rim of the Pacific maritime exercise off Hawaii, officials told USNI News.
“As the world’s largest international maritime exercise, RIMPAC provides a unique training opportunity designed to foster and sustain cooperative relationships that are critical to ensuring the safety of sea lanes and security on the world’s interconnected oceans,” 3rd Fleet officials said last week in an announcement. “The theme of RIMPAC 2022 is ‘Capable-Adaptive-Partners.’ Participating nations and forces will exercise a wide range of capabilities and demonstrate the inherent flexibility of maritime forces.”
About 25,000 military personnel will participate in RIMPAC 2022, which kicks off June 29 and runs through Aug. 4, with 38 surface ships, four submarines and more than 170 aircraft taking part in training at sea and ashore.
“It’s a return to a full-scale exercise,” Cmdr. Sean Robertson, a 3rd fleet spokesman, said Friday.
The biennial exercise, hosted by Pearl Harbor, Hawaii-based U.S. Pacific Fleet, was scaled down and shortened in 2020, due to the COVID-19 pandemic. That year, 10 countries participated in a force of 5,300 personnel along with 22 surface ships, one submarine and aircraft operating at sea over a two-week period in August 2020 off Hawaii.
Participating with U.S. service members are forces from 25 nations: Australia, Brunei, Canada, Chile, Colombia, Denmark, Ecuador, France, Germany, India, Indonesia, Israel, Japan, Malaysia, Mexico, Netherlands, New Zealand, Peru, the Republic of Korea, the Republic of the Philippines, Singapore, Sri Lanka, Thailand, Tonga, the U.K. and the U.S.
The forces will exercise a range of capabilities, including disaster relief, maritime security operations, sea control and complex warfighting, according to 3rd Fleet. That includes training in amphibious operations, gunnery, missile, anti-submarine and air defense, counter-piracy operations, mine clearance operations, explosive ordnance disposal, and diving and salvage operations.
While most of the training and exercise events will be held in and around the Hawaiian islands, a portion of the exercise – largely focused on mine warfare – will take place in Southern California, Robertson said.
This year’s international participants include Ecuador, a first for the South American nation, Robertson said.
While the Hawaii-based 3rd Marines have regularly joined in previous RIMPAC exercises, this year marks the first that it, as 3rd MLR, will participate in its recently-designated form. In March, the Marine Corps officially turned the previously infantry-focused regiment into one that would be structured with smaller, maneuverable, expeditionary advanced base detachments and equipped with anti-ship capabilities – changes more aligned with the service’s Force Design 2030 strategy to reshape its forces focused to “outpace a pacing threat,” as officials have said, in the Indo-Pacific.
That “pacing threat” includes China, which first participated in RIMPAC in 2014 and in 2016 but in 2018 the PLA Navy was disinivited due to China’s deployment of anti-ship missiles, electronic jammers in the South China Sea. Tensions in the region have only grown with continued operations and China’s militarization in the region and expanding global influence.
Third Fleet will lead the exercise as the multinational, Combined Task Force commander, with Royal Canadian Navy Rear Adm. Christopher Robinson as the CTF deputy commander, Japan Maritime Self-Defense Force Rear Adm. Toshiyuki Hirata as the vice commander and U.S. Marine Corps Brig. Gen. Joseph Clearfield, who is the Marine Forces Pacific deputy commander, as the Fleet Marine Force commander. Commodore Paul O’Grady of the Royal Australian Navy will command the maritime component and Brig. Gen. Mark Goulden of the Royal Canadian Air Force will command the air component.
This year marks the 28th iteration of RIMPAC, which first began in 1971 as an annual event but shifted to biennial in 1974. It follows on a March planning conference in Hawaii attended by 1,000 members of participating countries and a smaller staff exercise held in San Diego that “allowed its attendees to walk through scenarios in a computer-based format in advance of executing operations at sea off the coast of Hawaii this summer,” according to a Navy news story.
