The mission of the Covey Facs from Danang was to provide 24 hour coverage of the eastern part of the Tigerhound area; to include the southern portion of North Vietnam from Dong Hoi south to the DMZ. To interdict enemy supply routes from eastern Laos into the RSVN; to support U.S. Army Special Forces Operations (Prairie Fire); and to conduct visual reconnaissance of their Area of Operations (AO) for intelligence purposes.
In the fall of 1968, Covey Facs ceased their operations over the southern part of North Vietnam. In early 1973, as the war de-escalated, and prior to their de-activation, Covey Facs ceased their out-of-country operations and flew missions in support of in-country operations.
The mission of the Tigerhound Pleiku Detachment Covey Facs was to provide continuous coverage of the southern part of the Tigerhound area; to interdict enemy supply routes leading from southern Laos into the RSVN; to support the U.S. Army Special Forces Operations; and to conduct active reconnaissance of their assigned area for intelligence purposes.
In July of 1968, the mission of the Pleiku Covey Facs was increased to encompass a 30 mile span of Route 165 extending northwest of Chavane.
In June of 1970, the northern third of Cambodia was added to the Pleiku Covey's Area of Operations. To accomplish this mission, air assets were increased by eight aircraft and ten pilots.
