Located on a remote mountaintop in northern Laos, Lima Site 85 was a crucial base during the Laotian Civil War. It supported the Royal Lao government against Communist forces and helped prevent communism's spread in the region. Despite its secrecy and remoteness, Lima Site 85 was vital in U.S. efforts to combat communism in Southeast Asia. The base provided essential support for air operations, communications and ground support throughout the region.

Background

In the early 1960s, Laos became a crucial battleground in the larger Cold War conflict between the United States and the Soviet Union. The United States was concerned about the spread of communism in Southeast Asia. So it decided to provide support to the Royal Lao government in its fight against Communist forces. As part of its support, the military established a network of secret airbases throughout the country to aid in their efforts.

Located in northern Laos, Lima Site 85 was one of the most crucial bases for the US. It was strategically positioned near the border with North Vietnam, making it ideal for supporting US air operations over North Vietnam and Laos, while also acting as a critical communications relay for U.S. forces in the region.

A small group of American personnel and allies were stationed at Lima Site 85. Their responsibilities included maintaining and defending the base. This group consisted of Air Force crew members, communications specialists, and ground support staff. Designers created the base to withstand attacks, with hardened bunkers, reinforced tunnels, and camouflaged positions to make it challenging for the enemy to locate.

The US significantly escalated its involvement in the region by establishing Lima Site 85. It also established a series of secret airbases throughout the region. and a network of secret airbases throughout Laos. The military's actions were controversial and kept secret from the American public at the time. Nevertheless, Lima Site 85 and the other airbases played a crucial role in providing the military with a strategic advantage.

The LS-85 mountaintop area included radar shelters ("Operations") with antennas and interior equipment normally in/on mobile AN/MSQ-77 "control and plotting" and radar vans. "TACAN" is the box shelter for the AN/TRN-17 electronics with antenna on top, and "LZ" is for the nearby helicopter Landing Zone. Also not shown are the CIA airstrip and command post.

The Battle

On March 11, 1968, a force of North Vietnamese soldiers and Laotian Communist forces launched a surprise attack on the base, targeting it with mortars, rockets, and small arms fire. A group of about 19 Air Force personnel and their Hmong allies defended the base and were heavily outnumbered.

Defenders of Lima Site 85 bravely repelled enemy attacks with small arms, grenades and artillery. They took advantage of terrain to avoid detection. As the battle wore on, the defenders began to run low on ammunition and supplies. They had to carefully ration their supplies to prevent the enemy from overrunning their position. Despite being in a precarious situation, the defenders refused to give up without a fight.

On the fourth day, the US military launched a rescue mission to evacuate the survivors. Despite active attacks from the enemy, the military personnel showed bravery and skill. They successfully evacuated most of the personnel, preventing catastrophic loss of life. The operation involved multiple aircraft and ground forces and faced significant challenges. Despite the challenges, they were able to successfully evacuate most of the personnel at the base, preventing a catastrophic loss of life.
