The U.S. State Department has approved a possible Foreign Military Sale (FMS) of RGM-84Q-4 Harpoon Block II+ ER Grade B Surface-Launched Missiles and RGM-84L-4 Harpoon Block II Grade B Surface-Launched Missiles to Finland for an estimated cost of $622 million.
The Government of Finland has requested a possible sale of 100 RGM-84Q-4 Harpoon Block II Plus (+) Extended Range (ER) Grade B Surface-Launched Missiles, 12 RGM-84L-4 Harpoon Block II Grade B Surface-Launched Missiles, 12 RGM-84Q-4 Harpoon Block II+ ER Grade B Surface-Launched Upgrade Kits, four RTM-84L-4 Harpoon Block II Grade B Exercise Surface-Launched Missiles, and four RTM-84Q-4 Harpoon Block II+ ER Grade B Exercise Surface-Launched Missiles.
Also included are containers, spare and repair parts, support and test equipment, publications and technical documentation, personnel training and training equipment, technical assistance, engineering and logistics support services, and other related elements of logistical support. The estimated total case value is $622 million.
The Defense Security Cooperation Agency (DSCA) delivered the required certification notifying Congress of this possible sale on Feb. 5, 2018.
The DSCA said in a statement that this proposed sale will support the foreign policy and national security objectives of the United States by improving the security of a partner nation that has been, and continues to be, an important force for political stability and economic progress in Europe
Finland intends to use the missiles on its Hamina class fast attack crafts (FAC), Multirole Corvette ships, and Coastal Batteries. The missiles will provide enhanced capabilities in effective defense of critical sea lanes. The proposed sale of the missiles and support will increase the Finnish Navy’s maritime partnership potential and increase regional security capability. Finland has not purchased Harpoon Block II+ ER previously.
The principal contractor will be The Boeing Company, St. Louis, MO.
Harpoon is an all-weather, over-the-horizon, anti-ship missile system, developed and manufactured by McDonnell Douglas (now Boeing Defense, Space & Security).
The missile system has also been further developed into a land-strike weapon, the Standoff Land Attack Missile (SLAM).
The regular Harpoon uses active radar homing, and a low-level, sea-skimming cruise trajectory to improve survivability and lethality. The missile can be launched from submarines, surface ships, aircraft and land-based launchers.
The RGM-84 version is launched from Surface ships and fitted with a solid-fuel rocket booster that detaches when expended, to allow the missile’s main turbojet to maintain flight. In 2004, Boeing delivered the 7,000th Harpoon unit since the weapon’s introduction in 1977.
The Harpoon Block II Plus includes a new GPS guidance kit, reliability and survivability of the weapon, a new data link interface that enables in-flight updates, improved target selectivity, an abort option and enhanced resistance to electronic countermeasures. It can be launched from multiple air and surface platforms.
