"Atlantic Conveyor" was a 14,950 ton roll-on, roll-off container ship launched in 1969 that had been hastily converted to an aircraft transport and was carrying helicopters and supplies, including cluster bombs. Two Exocet missiles had been fired at a frigate, but had been confused by its defences and re-targeted the "Atlantic Conveyor". Both missiles struck the container ship on her port quarter and warheads exploded either after penetrating the ship's hull, or on impact. Witness Prince Andrew reported that debris caused "splashes in the water about a quarter of a mile away". Twelve men were killed and the survivors were taken to HMS "Hermes".
