The GBU-53/B SDB II (commercially “StormBreaker”) is built around a “tri-mode seeker” with “networked targeting” and a standoff range designed specifically to attack mobile threats such as air-defense systems, artillery, command vehicles, and logistics columns—capabilities the article says are enabled by the F-35’s sensor fusion and low-observable features.

Finnish F-35 programme director Col. (ret.) Henrik Elo said the SDB II “br[ings] the F-35 armament the capability the Finnish Air Force did not previously have,” and added that being able to strike moving targets “also in challenging weather conditions” will let Finland use the F-35 effectively for “Multi-Domain Operations across all defence branches.”

Defence Minister Antti Häkkänen emphasized the purchase is “a new type of capability” that “strengthens Finland’s defence capability even under demanding conditions,” and said the glide bomb “supports the effective use of F-35 materiel as part of the defence system.”

The procurement was framed not as a standalone weapons buy but as part of a broader programme package: the Caliber.Az report says it forms “part of a wider package associated with the programme,” while Nordic Defence Sector adds that the additional acquisition “supplements a Foreign Military Sales (FMS) procurement agreement concluded in 2023” under a Letter of Offer and Acceptance (LOA).
Finland has authorized its Defence Forces Logistics Command to buy approximately 150 GBU-53/B StormBreaker glide bombs for its incoming F-35A fighters, Defence Blog reported. The $34.2 million purchase, routed through U.S. Foreign Military Sales, gives Finnish jets the ability to hit moving targets in bad weather — a capability the Air Force previously lacked.
Defence Minister Antti Häkkänen called it "a new type of capability" that "strengthens Finland's defence capability even under demanding conditions." The authorization moves the programme from a notified U.S. Congressional intent, first flagged in November 2023, into a fully funded, active contract phase, according to Army Recognition.
What the StormBreaker Actually Does Differently
The GBU-53/B is built around a "tri-mode seeker" — millimeter-wave radar, infrared imaging, and a laser guide — that lets it track targets through smoke, dust, and rain. That matters because older bombs like the GBU-31 JDAM work well against stationary targets but struggle when the target moves. The StormBreaker can receive updated target coordinates while it is already in the air, according to Army Recognition.
The bomb weighs about 204 lbs and measures 70 inches long. Its small size is a key feature. An F-35A can carry eight StormBreakers inside its internal weapons bay, keeping the jet's stealth profile intact. Finland's F-35 programme director Col. (ret.) Henrik Elo said the weapon brings "the capability the Finnish Air Force did not previously have" — specifically the ability to strike moving targets "in challenging weather conditions" for what he called "Multi-Domain Operations across all defence branches," Defence Industry EU reported.
Finland Builds on a $9.4 Billion F-35 Foundation
Finland selected the F-35A in December 2021 to replace its aging F/A-18 Hornet fleet. It signed a Letter of Offer and Acceptance in February 2022 for 64 aircraft at roughly €8.4 billion — one of the largest defence purchases in Finnish history, according to GuruFocus. The first Finnish F-35As are expected to arrive in 2025 and 2026, with full operational capability targeted for 2030.
This SDB II deal supplements a broader FMS agreement concluded in 2023. Beyond the bombs themselves, the package covers spare parts, documentation, transport, and long-term manufacturer training and repair support. The total F-35 armament programme, including earlier weapon orders, exceeds $1 billion, Army Recognition reported.
Finland Joined NATO in 2023 — Now It Is Arming for It
Finland joined NATO in April 2023, sharing an 830-mile border with Russia. That context shapes why officials framed this buy in deterrence language. The StormBreaker's range — over 40 nautical miles against moving targets, over 60 nautical miles against stationary ones — means Finnish jets can engage mobile threats like missile launchers or armored columns without flying into Russian air-defense zones, according to Army Recognition.
Norway, another NATO F-35 operator, already uses the StormBreaker. Finland adopting the same weapon creates a more unified Nordic strike capability. Defence Minister Häkkänen said the glide bomb "supports the effective use of F-35 materiel as part of the defence system," Defence Blog reported. The purchase signals that Finnish F-35s are being built for offensive deterrence, not just patrol.
Who Makes It and What It Costs the U.S. Partner Network
RTX — formerly Raytheon Technologies — manufactures the StormBreaker. The U.S. Defense Security Cooperation Agency notified Congress of the potential Finnish sale on November 28, 2023, under DSCA Transmittal No. 23-68, pricing the specific SDB II tranche at $34.2 million. Congressional approval is required for all Foreign Military Sales of this type, Seeking Alpha noted.
Some Finnish fiscal critics have questioned the long-term cost of the FMS model, where spare-parts prices can shift with U.S. inflation and global demand. But those concerns have found little mainstream traction since Russia's invasion of Ukraine in 2022 reshaped the political debate around defence spending across the Nordic region, according to Army Recognition.
