The pilot from the 8th Fighter Wing suffered minor injuries when he ejected during a landing after a routine sortie Monday.
He was released in good condition, the 8th Fighter Wing said Wednesday in a news release.
The aircraft sustained damage, but no other base assets or property were damaged, it added.
Flying operations also resumed Wednesday after a 24-hour runway closure to verify it was safe for the use of all personnel and assets, according to a news release.
The 8th Fighter Wing initially said the runway had reopened at about 3 p.m. Tuesday. The incident occurred at about 3:30 p.m. Monday.
Public affairs officials couldn't immediately be reached for further comment.
"We are flying today because we have confidence in our maintainers and our pilots to execute the mission," wing commander Col. Tad Clark said in a statement.
The 8th Fighter Wing, which is based at Kunsan, has two fighter squadrons that perform air and space control roles, including counter air, strategic attack, interdiction and close-air support missions.
