As a result of the Cold War and with the expansion of a North American continental air defence system, Ramore was selected as a site for a United States Air Force (USAF) radar station, one of the many that would make up the Pinetree Line of Ground-Control Intercept (GCI) radar sites.

Each station was equipped with a Base Defence Force or BDF whose skills were sometimes tested against army units during practice drills.

It continued to serve as an advance warning system until its closure on 1 April 1974, along with two other stations in Ontario when they were deemed no longer necessary.

Two of the radar antennas were donated to the Military Communications and Electronics Museum in Kingston upon Ramore's closure.

In 1975, the station was sold to the Black River-Matheson township for $100,000 and was reopened as the Lava Mountain Lodge, a resort and drinking establishment.
