An extended response SLAM (SLAM-ER) first flew in 1997, doubling the SLAM’s range, as well as introducing Automatic Targeting Acquisition (ATA) technology. The air-launched Block 1 E (AGM-84E), known as the Standoff Land Attack Missile (SLAM), enabled the targeting of land-based assets. An air-launched variant followed soon after, first equipped on the Navy’s P-3 Orion in 1979, and later on F/A-18 Hornet and B-52H Bomber, among other aircraft. 2īy 1977, the Navy had deployed the Harpoon as its basic antiship missile for fleet-wide use. Navy recognized a widening gap in their capabilities and contracted McDonnell-Douglas to begin the Harpoon missile program. Following the sinking of the Israeli destroyer Eilat in 1967 by Soviet-made Styx antiship cruise missiles, the U.S. Navy began developing an antiship missile designed to target surfaced submarines.īecause the missile would target “whales”-naval slang for submarines-the missile was designated the Harpoon.
