Flashback: The Horsefly, Rover Joes, and the Birth of the Mosquitoes

Since the birth of flight, aircraft of all kinds have been used in war to observe the battlefield, survey the enemy position, and collect intelligence that could be used to help those fighting on the ground.

After World War I, when aircraft proved to be effective as weapons themselves, the military realized this “birds-eye-view” could be exploited to provide direct support to ground forces in the form of Close Air Support (CAS).

Coordinating the CAS mission was not an easy feat and required communication between the pilot in the air and the troops on the ground to ensure that the support provided from the air did not fall short of the enemy, or worse, hit friendly forces instead. These ground coordinators came to be known as Forward Air Controllers (FACs).

Starting in World War II, the Army Air Forces began developing a Tactical Air Control System (TACS) to further coordinate the air war. It employed FACs on the ground, known as “Rover Joes,” using Jeeps equipped with AN/ARC-1 radios to communicate with fighters in the air, and a Tactical Air Control Center (TACC) to ensure the right aircraft made it to the right place and dropped ordinance on the right targets. The Army even began to experiment with the concept of an Airborne FAC, flying liaison aircraft, like the L-4, to coordinate between Rover Joes and fighters to help spot and take out targets.

While this “Horsefly” system was highly effective in WWII, by 1950 the U.S. Air Force was flying a very different mission alongside UN coalition forces in Korea. The antiquated Rover Joe Jeeps could not keep up with the rough terrain and inconsistent battlelines of the Korean front, and the need for an Airborne FAC to coordinate strikes proved necessary once again.

So, the Air Force created the 6147th Tactical Control Squadron (Airborne) who flew the T-6 “Texan” low and slow over the Korean front, providing crucial support to the Korean TACS. These flyers called “Mosquitoes” flew a very dangerous mission in a very vulnerable platform to facilitate the air war in Korea.

Their story is just the beginning of a legacy of invention, and reinvention, as the Air Force tried to balance its strategic and tactical missions, searching for the best ways to support ground forces from above.
