#HARPOON HR11 SOFTWARE#

Whereas Blk IB and IA could perform either a low apogee pop-up trajectory or a sea-skimming approach in its terminal phase, the Blk IC can perform both. Introduced in 1985, the Blk IC differs from previous iterations in its flight path, guidance, and targeting technology. Additionally, Blk IB features improved electronic counter countermeasures (ECCM) for increased targeting precision. Rather than performing a pop-up maneuver, Blk IB missiles sea-skim toward its target in the terminal phase of flight.

#HARPOON HR11 SOFTWARE#

Introduced in 1982, this variant presents only slight changes to the flight profile and software of the Block IA. The UGM-84A Encapsulated Harpoon Weapon System (EHWS) is essentially the same as the RGM-84A, except it is launched from submarine torpedo tubes within a launching capsule.

There are two dedicated launchers for the Harpoon-the Mark 140 Mod-0 and the Mk 141 Mod-1-capable of firing one missile every two seconds. The missiles are equipped with a 224 kg HE warhead. 7 For guidance, the Blk IA models rely on inertial navigation for midcourse guidance and active radar during the terminal phase. 6Ĭonsequently, the AGM-84A has a longer range of 120 km compared to the RGM/UGM-84A, which has a range of 92.6 km. The AGM-84A is 3.85 m in length and 0.343 m in diameter, with a launch weight of 556 kg, whereas the RGM/UGM-84A measures 4.64 m in length with a diameter of 0.343 m, and a launch weight of 682 kg. For clarity, in 1973 the Navy determined the following designations for the Harpoon family: A= air-launched, R=surface ship-launched, U=underwater-launched, G=surface-attack, M=Guided missile.īecause the air-launched variant (AGM-84A) does not have jettisonable solid propellant boosters, it is shorter and lighter than its surface- and underwater-launched cousins. Since its introduction in 1977, the Harpoon has received multiple upgrades to its hardware and software, resulting in many variants. 4 The Harpoon Block II, unveiled in 2009, features autonomous, over-the-horizon range, and can execute both land and air strikes. 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.
