US partners with Indo-Pacific allies in WestPac Rumrunner exercise

More than 60 aircraft and 300 personnel from across the US Armed Forces have partnered with the forces of Indo-Pacific allies at Kadena Air Base, Japan, to participate in Exercise WestPac Rumrunner.

More than 60 aircraft and 300 personnel from across the US Armed Forces have partnered with the forces of Indo-Pacific allies at Kadena Air Base, Japan, to participate in Exercise WestPac Rumrunner.

With the evolving security environment in the Indo-Pacific and to further support a safe and secure region, the US Air Force's 18th Wing spent months designing WestPac Rumrunner as an exercise to train counter-air capabilities and strengthen joint interoperability.


In addition to air tactics and joint interoperability, Airmen were charged with ensuring continuous airpower by using tactics derived from Pacific Air Forces’ agile combat employment, or ACE, concept of operations. 

Captain Brian Davis, 67th Fighter Squadron F-15C Eagle evaluator pilot and WestPac Rumrunner exercise director, explained the importance of exercises like WestPac Rumrunner: "As we executed this first iteration of Rumrunner, the exercise development team monitored how well our distributed joint forces came together and applied elements of ACE to disperse, recover and rapidly resume operations.

"The Rumrunner team looks forward to how we will continue to evolve and hone our procedures in the future."

As the largest combat wing in the Air Force, Kadena Air Base was able to deploy a wide array of aircraft to simulate a realistic training scenario along with support from joint forces.

The adversary air force primarily consisted of the Navy’s F/A-18E/F Super Hornets and Air Force’s Eagles, but the home team brought overwhelming joint capabilities to deny the adversarial advance.


But, most unique to this exercise was the air-to-air and air-to-ground command and control provided by the Air Force’s E-3 Sentry, Navy’s E-2 Hawkeye and 18th Wing’s 623rd Air Control Squadron, all of whom worked seamlessly to ensure battlespace situational awareness while expertly handing-off key targeting information to the US Army’s 1-1 Air Defense Artillery’s Patriot surface-to-air missile battery.

Marine Air Control Squadron 4 helped track the operations and were able to test integration capabilities for their systems at Marine Corps Air Station Futenma, Japan.

As part of the ACE strategy, to extend and improve the availability of aircraft during a contingency, Air Force maintenance Airmen were positioned on the ground at Marine Corps Air Station Futenma to provide a quick refuel so the aircraft could swiftly be launched and returned to the fight.

Lieutenant Colonel Johnny West, 18th Maintenance Group deputy commander, said, "The ACE concepts being developed are not confined by current maintenance doctrine or tactics.

"Our senior leaders are encouraging maintainers and logisticians to be more creative and assertive at lower levels to overcome generation and re-generation limitations that could occur in a highly-contested environment. Today’s Rumrunner exercise allowed us to practice operating in a simulated austere environment, which is fundamental to the ACE concept, and our maintainers successfully refueled F-15s and launched them back into the air," LTCOL West added. 

Overall, Brigadier General Joel Carey, 18th Wing commander, described WestPac Rumrunner as a success and a valuable learning tool for Pacific Air Forces and joint services.

"This event was a big win for us in the Pacific. Being able to test our ACE capabilities with our joint partners highlights the importance of interoperability and the capabilities of our Airmen and sister services. Working in conjunction with the Navy, Army and Marine Corps was crucial to the success of Rumrunner and its ability to be a powerful learning tool moving forward," Brig Gen Carey explained.
