The booster secion consists of a solid fuel rocket and arming and firing device. The control section consists of four electromechanical actuators which use signals from the guidance section to turn four fins, which control missile motion. The sustainer section has four fixed fins, which provide lift. This provides the thrust to power the missile during sustained flight. The sustainer section consists of a fuel tank with JP-10 fuel, an air inlet duct and a jet engine. The warhead section can be replaced by an exercise section, which transmits missile performance data for collection and analysis. ![]() It is designed to explode the warhead after impacting the target. The safe-and-arm/contact fuze assembly ensures the warhead will not explode until after the missile is launched. The warhead section consists of a target-penetrating, load-carrying steel structure, containing 215 pounds of high explosive (DESTEX) and a safe-and-arm/contact fuze assembly. ![]() After seeker target acquisition, the DC/PS uses seeker data to guide the missile to the target. After launch, the DC/PS uses the missile acceleration data from the ARA and altitude data from the radar altimeter to maintain the missile on the programmed flight profile. Prior to launch, the DC/PS is initialized with data by the Command Launch System. The MGU consists of a three-axis attitude reference assembly (ARA) and a digital computer/power supply (DC/PS). The guidance section consists of an active radar seeker and radome, Missile Guidance Unit (MGU), radar altimeter and antennas, and a power converter. This Harpoon Block II missile incorporated Global Positioning System assisted inertial navigation, which gives the system both an anti-ship and a land attack capability. ![]() Under a 1998 agreement between Boeing and the Navy, an advanced upgrade to Harpoon missile was developed. The Harpoon missile can also be launched from submarines. The Harpoon was also adapted for use on B-52H and F-16 aircraft, and is currently being integrated on the F-15 (the USAF only uses Harpoon on its B-52H bombers, the F-16/F-15 integration is for non-US customers). USAF F-16C block 40 #87353 carrying an AGM-84 'Harpoon' all-weather anti-ship missile for trial purposes on May 1st, 1992.The A/R/UGM-84 was first introduced in 1977, and in 1979 the air-launched version was first deployed on the Navy's P-3C Orion aircraft.
