Air Force Lt. Gen. Terrence J. O’Shaughnessy will become the new leader of the Air Force in the Pacific, the Pentagon announced Friday.

O’Shaughnessy replaces Gen. Lori J. Robinson, who took over U.S. Northern Command last month.

O’Shaughnessy is currently deputy commander of the United Nations Command Korea, deputy commander of U.S. Forces Korea and commander of the 7th Air Force at Osan Air Base.

O’Shaughnessy also was nominated to receive his fourth star. The promotion is subject to Senate confirmation.

As the new commanding general of Pacific Air Forces, O’Shaughnessy will serve as the air component commander for U.S. Pacific Command and executive director of the Pacific Air Combat Operations Staff at Joint Base Pearl Harbor-Hickam.

O’Shaughnessy is a 1986 graduate of the Air Force Academy.

He has commanded at the squadron, group and wing levels, including the 57th Wing, Nellis Air Force Base, Nev.; the 35th Fighter Wing as Misawa Air Base in Japan; and the 613th Air and Space Operations Center.

Before his current position, O’Shaughnessy was the Pacific Command’s director of operations, responsible for joint operations in a region encompassing more than half the globe and 36 nations.

He is a command pilot with more than 3,000 hours in the F-16 Falcon, including 168 combat hours.

Pacific Air Forces, headquartered at Joint Base Pearl Harbor-Hickam, is one of nine major Air Force commands.

The Air Force command consists of 45,000 members, including Air National Guard members, reservists and civilians.

Also announced Friday, Brig. Gen. Gregory Guillot, currently director of strategic plans, requirements and programs at Pacific Air Forces, will become chief of staff.

He will succeed Maj. Gen. Kevin B. Schneider, who will become the new chief of staff at Pacific Command.

Guillot’s replacement will be Brig. Gen. Craig D. Wills, now executive officer to the commander at Pacific Air Forces.
