262:. While the facility was designed for 500 occupants, it was in reality occupied by about 350. During its period of operation the nature and details of the base were secret. In 1959 operations at Salbert were terminated and the force reduced to maintenance and security, with the surveillance function detailed to Ballon de Servance. The station had been fully operational for scarcely two years. The station was decommissioned due to the obsolescence of its radars, whose short range, low altitude coverage and poor performance made them of limited use. Consolidation and automation of radar surveillance made the Salbert facility obsolete. The station was fully maintained in operating order until 1972, when it was turned over to Belfort.
