During the Falklands War Seaslug was only launched once against an aircraft target, by without success. On 21 May 1982 in Falkland Sound, the "Antrim" which had already had an unexploded 1,000 lb bomb pass through the Seaslug magazine, fired a single missile (some sources say two) at one of a second wave of attacking IAI Dagger fighters. It was unguided because the aircraft was too low to be acquired; the launch was intended to deter the pilot and to remove the exposed missile from the ship because it posed a fire hazard. The first combat use in the surface-to-surface role was during a shore bombardment on 26 May, when fired Seaslugs at Port Stanley Airport claiming the destruction of a number of helicopters and a radar installation. A total of eight Seaslug Mk 2 missiles were launched in theatre by the two ships armed with them, including two missiles jettisoned by "Glamorgan" after she was hit by a land-launched Exocet missile on 12 June. Also during 1982, the Mk2 was used as a trials target for Seadart, but there were reliability problems with both systems.
