Long Reach: Finland’s GPS-Guided Rocket Launchers


ATACMS firing



Finland is busy modernizing its forces within its limited budgets, fromair defense upgrades to new stealthy cruise missiles and upgrades for its F/A-18 Hornet fighters. In June 2012, the Finns convinced the US State Department to issue its formal request to buy long-range ATACMS missiles, which are able to work with Finland’s newly-upgraded M270 tracked MLRS rocket launchers.
American 227mm MLRS systems offer shorter reach than Russia’s 300mm SMERCH-M rocket launchers, for now. By replacing a box of 6 MLRS rockets with a single Army TACMS missile, however, the equation changes dramatically…

TACMS vs. MLRS pod


Fired from a modified M270 MLRS launcher (2 missile capacity), the MIM-140/ M-39Army Tactical Missile System(ATACMS) is designed for deep attack of enemy second-echelon forces, at ranges beyond other cannons and rockets. Each ATACMS missile box replaces a similar-sized box of 6 guided or unguided 227mm rockets, with ranges from 40-70 km depending on the version used.
In contrast, the extended range Army TACMS Block IA operates at range up to 300 km day or night, and in all weather conditions. The Block IA missile uses an inertial system plus GPS to guide it accurately over the target area, delivering its 500-pound unitary warhead to hit the target in a final dive. That angled descent feature is specially well suited to urban targeting, a capability that proved itself out in battles like Tal Afar during Operation Iraqi Freedom.
In Finland’s case, ATACMS’ 300 km range gives it a tremendous radius of fire support for Finnish forces, which makes it very difficult for the Russians to find and suppress the launch vehicles. That fits well with Finland’s total defense strategy. It’s also worth noting that ATACMS’ range would allow it to be fired from Helsinki, and hit targets in St. Petersburg.
