NATO allies are linking their defenses together to better hunt and kill drones on its eastern edge

The US and its NATO allies are boosting their ability to detect, track, and target drone threats along the alliance’s eastern edge, its border with Russia.

Through rapid 90-day testing cycles designed to replicate real situations, US forces, Baltic allies, and defense companies are building a shared data network for faster decision-making. The effort links sensors that detect aerial threats with counter-drone systems that can destroy them, aiming to improve defenses against Russian-style drone attacks, including Shahed-type systems.

US and Estonian forces executed exercise Digital Shield 2.0 earlier this month, the second stage in an ongoing testing series.

The exercise “was really born from an initiative to integrate different sensor types into an easily accessible and shareable integrated sensor architecture, or an air picture,” US Army Capt. Micah Maule, plans officer for the 10th Army Air and Missile Defense Command, told Business Insider.

While the first Digital Shield proved the concept, the second expanded the scale, adding more sensors to detect larger uncrewed aerial systems such as Shahed-type drones and additional air-defense and counter-UAS radars to sharpen the picture of incoming threats.

Those systems feed into a common command-and-control network using commercially developed software, creating a streamlined flow of surveillance data that operators can view in a single air picture before deciding how to respond.

“So you could actually task effectors to go out and destroy drones from the same common operational picture,” Maule said.

Digital Shield 2.0 included several simulated scenarios that could become real-world threats, including cyberattacks disrupting operations, high-stress conditions with lots of drone targets, and a live-fire situation running the entire process against Shahed replicators.

Adding more sensors layers the defenses, but it also increases the volume of incoming data. Maule said the goal of the shared command-and-control system is to merge those inputs into one clear picture, reducing the cognitive burden on operators.

An advantage of the design is that the system can be operated farther from the front, out of range of many types of drones, and that it feeds data to multiple partners for heightened awareness.

The rapid pace of the Digital Shield testing reflects the Pentagon’s Silicon Valley-style “move fast, fail fast, fix fast” approach for developing new technology. It also pressures industry partners to keep up. Vendors must meet strict integration requirements, and the swift development cycle forces faster fixes and upgrades based on field feedback.

Digital Shield is an example of the work being done as part of the new Eastern Flank Deterrence Line initiative, which is led by the US and NATO. The effort is intended to build a robust defense against Russia that can detect drones across wide areas and counter them with lower-cost solutions.

Artificial intelligence is also being integrated into the initiative to analyze sensor data faster and speed up decisions on how to respond.

One persistent problem remains the cost of stopping cheap drones.

“We have to beat the cost curve,” Maule said. “If the UAS is a couple or tens of thousands of dollars, you can’t be using extremely expensive interceptors.” The US and its allies have learned that lesson from Ukraine and in the Middle East.

NATO allies are buying this rugged 6×6 armored vehicle built in Finland for Arctic war

Alarms blare over the factory floors, and work at Patria’s Hämeenlinna facility grinds to a halt.

The soft thrum of an explosion echoes through the campus. Moments later, roughly 700 workers continue making their armored vehicles bound for Japan, Sweden, Slovakia, and other countries. The blast is not a test-firing of its new combat vehicle, but part of the construction for its expanding manufacturing facility.

Patria, Finland’s largest defense company, is planning to nearly double production at its main hub just north of Helsinki, clearing rocks with explosives on-site to make way for several new assembly lines.

The Hämeenlinna factory manufactures Patria’s 8×8 armored personnel carrier and a relatively new, up-and-coming vehicle: a wheeled 6×6 troop transport that’s receiving surging demand from northern and western Europe.

Work on the 25-foot-long, 17-ton vehicle began in 2020 under a joint program between Finland and Latvia called the Common Armored Vehicles System. Both countries sought a cost-effective, mass-produced armored vehicle that could be used by their militaries for interoperability.

Latvia has since sent at least 42 of these vehicles to Ukraine, armed with heavy machine guns and rolled out in batches over the last year. The vehicle can cross tundra and even rivers while shielding up to 10 troops it carries from land mines and artillery fire to get them to forward positions.

When Business Insider visited Patria’s factory, representatives for the company — which is majority-owned by the state of Finland — said the firm wasn’t authorized to share details about the 6×6’s performance in Ukraine.

But the CAVS 6×6 program has been quickly drawing attention from the rest of Europe: What began as a partnership between two countries has expanded into a consortium of seven member states.

Sweden joined the Common Armored Vehicles System program in 2022, followed by Germany, Denmark, the UK, and Norway in subsequent years.

Finland and Latvia have placed orders for just under 500 of these vehicles, while Sweden has requested 415 of the 6×6s to be delivered over the next five years. Stockholm’s latest order for 94 vehicles, announced in early December, priced each one at about $1.75 million.

Germany has become the program’s largest buyer, signing contracts in mid-December to acquire 876 of the 6×6 vehicles, valued at $2.3 billion. These vehicles will be split into four variants, including one that features a mortar turret.

Meanwhile, Denmark, which joined the program this year, has already placed an order for 129 6×6 vehicles.

The UK and Norway are still negotiating 6×6 orders with Patria.

Inside the CAVS 6×6

The CAVS 6×6 can accommodate roughly 10 troops, along with a typical crew of two or three, and features up to NATO standard level 4 armor designed to withstand direct hits from large-caliber machine gun fire, mine explosions, and nearby artillery blasts.

The CAVS 6×6 competes with other wheeled troop transports, such as Rheinmetall’s Boxer and General Dynamics Land Systems’ Stryker, the latter of which is extensively fielded by the US Army.

The Finnish company said it can tweak the vehicle for each customer’s needs, but a typical model features climate control that enables the vehicle to operate in temperatures as low as -40°F.

“Inside, it will be comfortable enough to easily survive. We are talking about temperatures of the plus centigrades,” Mikko Rantanen, Patria’s director for 6×6 vehicle programs, told Business Insider from inside the rear compartment of one of the vehicles.

The 6×6’s rear interior is spartan: Cloth-covered metal-frame seats and headrests for five people on either side, with space behind each seat for equipment and small arms.

There’s just enough room for a soldier to sit with their knees touching the opposite passenger’s. A few fire extinguishers inside are connected to an automatic suppression system that can detect a blaze in the rear cabin.

Screens allow troops to see outside the vehicle through exterior cameras, while a rear hatch provides the option of fitting a machine gun or crewed weapon module on top of the 6×6.

On the right-hand side of the vehicle, a small passageway also lets troops pass between the rear compartment and the driver’s cabin, which resembles that of a truck and features an automatic gearbox.

Optional propellers on the 6×6’s underside enable it to transition seamlessly from traversing land to crossing small bodies of water, such as rivers or lakes.

“We can enter the water without needing preparation in this configuration,” said Rantanen.

However, the 6×6’s speed in the water is just under 5 mph, and Rantanen added that it’s not meant to be a landing craft or amphibious assault vehicle.

On land, it’s designed to drive at speeds of over 60 mph, easily cross trenches that are four feet wide, and surmount obstacles about two feet high.

Moving fast in the Arctic

Building weapons and vehicles specifically for arctic terrain is a specialty for contractors in Finland, a country renowned for holding off the Soviet Union for over 100 days in deep snow and dense forest during World War II.

Patria said that while the 6×6 can be outfitted for various terrain types, including the desert, the arctic domain is its forte.

Snow isn’t the only challenge in arctic warfare. Few roads are available on Finland’s border with Russia — the priority threat for NATO — and its vast hinterland is peppered with thousands of small lakes and marshland that can bog down armored transport.

“In the wintertime, it’s snow,” said Petri Hepola, Patria’s executive vice president for sales and marketing and its chief program officer for the F-35. “In the summer, lots of wet soil and swampy areas. One of the most important features is how fast you can move your troops and tools through these areas.”

Finland and Norway are the only two members of Patria’s 6×6 program that share Arctic borders with Russia.

However, as northern Europe, especially the Baltic and Nordic states, grows increasingly concerned about conflict with Moscow, the Kremlin has been bolstering its military presence in the high north, repopulating key bases and transforming its Arctic fleet into a separate strategic theater.

Since Finland joined NATO in 2023, alliance forces have been rushing to train on the country’s terrain and frigid temperatures, making it one of the most active spots for joint exercises in recent years.

“Our products have been surviving very well in that environment,” Hepola said.

Gearing up for 2027

With an order backlog of nearly 2,000 6×6 vehicles, Patria hopes its new facility in Hämeenlinna will be ready for production by 2027. The factory campus serves only the tail end of the entire manufacturing cycle, which can take weeks in most cases, or several months for more complicated variants.

Inside, hundreds of workers conduct welding, surface treatment, assembly, tests, and other final processes that can each take weeks to complete. Dozens of vehicles line the factory floors, and dozens more sit in parking lots, each marked with a flag to designate the country for which it has been modified.

Before delivery, each one is supposed to be driven at least 200 km, or 124 miles.

Rantanen, director of the 6×6 program, said Patria has been integrating counter-drone systems, such as jammers, on the vehicle.

Armored vehicles in Ukraine have especially struggled against pervasive minefields and small drones with explosive payloads, some of which are controlled via a fiber optic cable connection that can’t be jammed. In response, soldiers there have relied more on firearms such as shotguns and machine guns to counter such attacks.

Rantanen said Patria hasn’t yet officially added any kinetic weapons that can take down drones.

“The drone threat is currently evolving at such a speed that it’s hard to keep track of it closely,” he said. “But we are hard at work for the countermeasures against drones as well.”
