OSAN AIR BASE, Republic of Korea -- For five decades, the 5th Reconnaissance Squadron has been the unblinking eye in the sky, serving as one of the most critical intelligence assets on the Korean Peninsula.
To celebrate their golden anniversary, members of the squadron raised their glasses to honor service, sacrifice and tradition during the 5th RS 50th anniversary banquet at Osan Air Base, Republic of Korea, May 2, 2026.
Known as the “Blackcats”, the squadron has flown more than 17,000 operational U-2 sorties at an unmatched 98% mission-capable rate, making the 5th RS the most reliable intelligence asset in the Indo-Pacific theater.
“The intelligence we gather, the early warning we provide, and the deterrence we enforce ensure that our South Korean partners, our U.S. forces, our family and friends both here and back home, are never caught unaware,” said Lt. Col. Michael Ryan, 5th RS commander.
After an engagement between U.S. and adversary forces in 1976, known as the "Korea Tree Incident" at the Demilitarized Zone, the 5th RS was crucial in providing continuous monitoring and coverage of the area, supplying intelligence to help prevent further escalation of conflict.
“The 5th Reconnaissance Squadron has been a critical part of the U.S.-ROK Alliance,” said U.S. Air Force Col. Ryan Ley, 51st Fighter Wing commander. “Their mission has enabled combined operations, friendly interoperability and ensured that the U.S. and the ROK forces stand together.”
Beyond military operations, the 5th RS has also supported humanitarian efforts, like assessing flood damage in the ROK and surveying the devastation caused by the Mount Pinatubo eruption in the Philippines.
Over the years, the 5th RS mission has evolved alongside rapid technological advancements and changing geopolitical realities.
Originally operating the U-2R aircraft after relocating to the ROK in 1976, the squadron upgraded to the new U-2S in 1995. The modernization introduced a new engine and a full analog-to-glass cockpit, significantly improving endurance, fuel efficiency, and mission capability.
Despite its modernization, the 5th RS remains deeply connected to its historical roots.
When we call ourselves the Blackcats today, we are directly honoring the sacrifice, the heritage and the unbreakable courage of Detachment H. We do not just wear a patch; we carry the weight of their legacy on every single mission we launch.Lt. Col. Michael Ryan
From maintenance crews to pilots and civilian contractors, the 5th RS carries the Blackcat legacy forward with a singular focus on executing the mission.
Looking ahead, the squadron intends to continue building on that legacy providing persistent deterrence in the region.
As regional security challenges continue to evolve, the Blackcats’ combination of heritage, adaptability and technological superiority underscores the 5th RS as a cornerstone of intelligence operations on the Korean Peninsula.
