Following terrorist attacks on 27 December 1985 in the Rome and Vienna airports, a series of Freedom of Navigation
operations in the Gulf of Sidra (Operations in the Vicinity of Libya, OVL) were approved. Code-named `Attain Document,' the first two (26-30 January and 12-15 February) occurred without incident, During `Attain Document III (23-29 March 1986), two SA-5 missiles were shot at U.S. aircraft by a SAM Site on 24 March.

"Three carrier task forces of the Sixth Fleet with 225 aircraft assembled off the Libyan coast for maneuvers in March 1986. On March 24, six SA-5s were launched from the new missile base at Surt against American aircraft. None was hit, however, because the SA-5, with a range of 240 kilometers, could threaten high-altitude reconnaissance aircraft over the Gulf of Sidra but was relatively ineffective against high-performance jet fighters. Subsequently, the missile site was put out of action by carrier-based A-6 Intruders firing High-Speed Anti-Radiation Missiles (HARMs), that homed in on the Libyans' radar guidance signals. A second strike followed the next day to knock out a replacement radar unit. Although Soviet technicians were believed to be present to oversee the installation and operation of the SA-5 batteries, none was reported injured in the exchanges. "
