Muang Phalan TACAN Site was established by the U.S. Air Force in April 1967 as part of
Operation Bright Light to create a network of
TACAN sites to support air operations over
southern Laos and
Vietnam. The site operated as TACAN Channel 77. On 25 December 1967 the site was attacked by the
People's Army of Vietnam who overran the facility killing the two "sheep-dipped" technicians from the
1st Mobile Communications Group. A replacement TACAN site was installed at
Mukdahan, Thailand. ==Current use==
