Boeing conducted the first flight tests of the Harpoon Block II Update (HIIU) at the Point Mugu Naval Air Station in California, United States. The updated version underwent improvements in almost all systems to address obsolescence and meet growing demand for the missile.
The tests, conducted from an F-15SA, confirmed the expected performance in propulsion, guidance, navigation, and control.
The Harpoon Block IIU is an evolution of the previous model, incorporating JDAM bomb and SLAM-ER tactical missile technologies. The current version features enhanced internal equipment for different configurations and to ensure production continuity, although specific details of the modifications have not been disclosed. Missile delivery is planned for 2026.
In April 2023, Boeing signed a \$629.7 million contract to supply 400 units of the Harpoon Block II Update along with support equipment, with delivery to Taiwan scheduled through March 2029. The Asian country will also receive 100 coastal launchers, radar stations, and other equipment.
Meanwhile, the U.S. Navy and Raytheon are working on new seeker heads as part of the Missile Life Extension Program.
