VO-67

Observation Squadron 67 (VO-67) was a secret United States Navy military intelligence aircraft squadron based in Thailand during the Vietnam War. Created in February 1967, the unit was deactivated in July 1968. During its period of activity, the squadron mainly flew missions over the Ho Chi Minh trail in Vietnam and Laos implanting electronic sensory devices to detect North Vietnamese Army and supply movements along the trail.

The squadron flew OP-2E Neptune aircraft. Three unit aircraft were lost on combat missions with a total of 20 men killed. The unit received the Navy Unit Commendation and in May 2008 VO-67 was awarded the Presidential Unit Citation for its highly classified missions and for intense aerial support of the Marine fire base at Khe Sanh, South Vietnam during the 1968 Tet offensive. The Arleigh Burke class destroyer, USS Milius (DDG-69) is named for Commander Paul L. Milius who received the Navy Cross for saving his seven man crew while serving with VO-67. Commander Milius was lost in combat over the Ho Chi Minh Trail in 1968.

The squadron was awarded the Presidential Unit Citation ribbon and Navy Unit Commendation ribbon. Enlisted air crews were also awarded Marine silver Combat Air Crew wings for support of Khe Sanh fire base during 1968 Tet Offensive.
