Task Force Commando Buzz Overview
The 193rd Tactical Warfare Squadron (TWS), Pennsylvania Air National Guard, was tasked to operate
Task Force Commando Buzz operation from Korat RTAFB. Purpose of Commando Buzz was to receive the Radio
Cambodia programming then rebroadcast those radio programs from altitude so all of Cambodia, especially those
in fringe areas, could receive the Radio Cambodia programing. Initially classified secret, the Commando Buzz
operation was changed to Top Secret in July 1970. Task Force Commando Buzz was declassified in 2002.
To accomplish the Commando Buzz mission the 193rd TWS arrived at Korat RTAFB on July 31, 1970 with their
Lockheed EC-121S aircraft. Fifty eight members of the 193rd TWS came to Korat RTAFB including 11 officers
and 47 enlisted airmen. Of the 58 members of the 193rd TWS twenty were aircrew, 38 support personnel. Sources
vary on the number of EC-121S aircraft, some say at least 5 aircraft were converted to EC-121S radio relay
configuration. Other sources indicate that as many as 12 aircraft were converted to EC-121S configuration.
Upon departure from the U.S. CONUS the plan was for Task Force Commando Buzz to operate for 179 days. The 193rd
TWS arrived at Korat RTAFB on July 31, 1970. Korat RTAFB was selected because of the presence of the 553rd
Reconnaissance Wing with their Lockheed EC-121R aircraft. While the 193rd TWS was mostly self sufficient, the
553rd Reconnaissance Wing provided the parts supply, as well as ground equipment and personnel from the 553rd AMS,
553rd FMS and 553rd OMS as needed. These maintenance technicians were very familiar with the EC-121 and had
shop and test equipment to support Task Force Commando Buzz.
First Commando Buzz mission was flown on August 6, 1970. The radio relay Task Force Commando Buzz missions
were flown until December 23, 1970. By late December 1970 the Cambodian government had installed additional
ground transmitters so the fringe areas of Cambodia were now covered adequately by the ground transmitters.
The 193rd TWS along with their Lockheed EC-121S aircraft returned to the CONUS on January 3, 1971.

Wing history, declassified by the Air Force Historical Research Agency in 2002.

Lockheed EC-121S Images at Korat RTAFB
The images below are also shown on the 553rd Reconnaissance Wing Maintenance Tehnician page.
Note that upper dome on the EC-121S, it is an unique size and shape. This is not the same upper
dome which the Task Force College Eye Lockheed EC-121D, EC-121T (or the EC-121H) used. The EC-121S flew
without tip tanks.
For a 6 month period in 1970 the Pennsylvania Air National Guard
flew the Lockheed EC-121S out of Korat. One book I have on the
Lockheed Constellation, "Lockheed Constellation," by
Peter M. Bowers and Curtis K. Stringfellow, indicates only 5
aircraft were modified to this standard. The EC-121S aircraft
were flown and maintained by the Pennsylvania Air National Guard.
While at Korat the 553rd Recconaissance Wing provided service
facilities. Shown here is a photo of an EC-121S in
the hangar undergoing maintenance. Here is another view of an
the flight line. Note the unusal antenna, this is not the
same as the height finder antenna found on the EC-121D and
EC-121H, and also note that no tip tanks are fitted. Both images
provided by Greg
Krzyzak. These EC-121S images added 09/05/01,
This image shows two
EC-121S aircraft on the flight line at Korat RTAFB. This image was taken from the
window of a 2 baht bus going into Korat city. The EC-121S aircraft are on the right
with the white tops. My thanks to John Tomany for
sending this image. Color, about 29K, added 06/29/99, updated 12/12/14.
