Turkish defense giant ARCA is breaking ground in Estonia this month to build a $200 million ammunition factory, marking a rare deepening of military-industrial ties between NATO’s eastern flank and Ankara. The facility—set to produce 100,000 rounds of 155mm artillery shells annually—comes as Estonia’s defense spending surges post-Ukraine war, while Turkey’s arms exports to Europe hit a record $1.2 billion in 2025. Here’s why this deal reshapes both the Baltic security calculus and NATO’s supply chain vulnerabilities.
**Here’s the bigger picture:** This isn’t just another defense contract. It’s a geopolitical pivot with three critical dimensions: a test of Turkey’s non-aligned neutrality in a fracturing NATO, a hedge against EU sanctions on Russian ammunition, and a case study in how modest states leverage foreign investment to offset defense gaps. With Estonia’s population smaller than Istanbul’s, the factory’s output will directly feed into Finland’s NATO accession plans—and could force Sweden to accelerate its own ammunition stockpiling.
Why Estonia? The Baltic’s Ammunition Dilemma
Estonia’s defense ministry has been scrambling to replace Soviet-era stockpiles depleted by training exercises with Ukraine. The ARCA deal—announced just days after Estonia’s parliament approved a 30% defense budget hike—solves two problems at once: it secures local production of NATO-standard munitions and diversifies supply away from traditional European suppliers like Germany and France, whose factories are stretched thin.
But there’s a catch: Estonia’s tiny domestic market (just 1.3 million people) can’t justify the factory’s scale alone. ARCA’s real target is the broader Baltic region. Lithuania and Latvia—both locked in a tense standoff with Russia over Kaliningrad—are quietly negotiating similar deals with Turkish firms. “This is about creating a regional hub,” says Dr. Sinan Ülgen, former Turkish ambassador to the U.S. And director of the Istanbul-based EDAM think tank. “Turkey is positioning itself as the go-to supplier for NATO’s eastern members, not just because of cost—its shells are 20% cheaper than German or French equivalents—but because of speed. Estonia needs shells now, and Ankara delivers.”
Historically, Turkey’s defense exports to Europe have been limited to patrol boats and drones. This factory represents a bold expansion into high-end artillery—a sector dominated by EU members. The move comes as Brussels debates whether to include Turkish defense firms in its 2024 Defense Industrial Strategy, despite Ankara’s refusal to join the EU’s PESCO framework.
The NATO Tightrope: Turkey’s Neutrality Under Stress
Turkey’s deepening ties with Estonia sit uneasily alongside its de facto alliance with Russia in Syria and the Black Sea. President Recep Tayyip Erdoğan has repeatedly warned against NATO expansion into the South Caucasus, yet here he is arming a Baltic state that hosts U.S. Missile defense systems. The contradiction isn’t lost on European diplomats.
What’s less obvious is how this deal fits into Turkey’s broader strategy. With Sweden’s NATO accession stalled by Hungarian opposition—and Finland’s integration still fragile—Ankara is betting that deepening military cooperation with the Baltics will give it leverage in Brussels. “Turkey is playing the long game,” explains Dr. Katrin Kivimaa, senior researcher at the Tallinn University of Technology. “By supplying Estonia, it’s not just selling weapons—it’s embedding itself in NATO’s supply chains. That makes it harder for the EU to isolate Turkey over issues like Cyprus or the Eastern Mediterranean.”
“This factory is a Trojan horse. Turkey isn’t just selling ammunition—it’s inserting itself into the DNA of NATO’s eastern defense architecture. Once that happens, kicking them out becomes politically toxic.”
Supply Chain Geopolitics: Who Wins When Europe Runs Out of Shells?
The ARCA factory’s timing couldn’t be worse—or better—for global ammunition markets. With Ukraine’s counteroffensives grinding to a halt and European stockpiles critically low, the EU is facing a 150% shortfall in 155mm shells by 2027, according to a leaked European Parliament report. Turkey, meanwhile, has quietly become the world’s third-largest arms exporter, behind only the U.S. And Russia, with 40% of its sales now going to Europe.
Here’s the market ripple effect:
- Price War: ARCA’s shells, priced at €1,200 per round (vs. €1,500 for German Rheinmetall), will pressure EU producers to cut costs or risk losing contracts.
- Sanctions Workaround: Estonia’s purchase bypasses EU sanctions on Russian ammunition by sourcing from a third country—setting a precedent for other NATO states.
- Stockpile Diversification: Finland and Sweden, which have avoided large-scale arms deals with Turkey, may now face pressure to negotiate similar agreements to avoid dependency on U.S. Or French suppliers.
The factory’s location in Estonia—just 300 km from Russia’s Kaliningrad exclave—also introduces a new layer of risk. While NATO insists the facility won’t be targeted, Russian state media has already framed it as “proof of Western aggression.” In a recent op-ed, Kremlin-linked analyst Konstantin Zatulin warned that the plant “turns Estonia into a forward operating base for NATO’s artillery war against Russia.”

The Long Game: What Happens Next?
Three scenarios are emerging:
- The Baltic Hub: If successful, ARCA’s factory could spawn a network of Turkish-run ammunition plants across the Baltics, turning the region into a de facto NATO arms production zone—directly challenging EU defense autonomy.
- The EU Backlash: Brussels may retaliate by tightening export controls on dual-use tech to Turkish firms, forcing ARCA to source critical components from China or Iran.
- The Russian Gambit: Moscow could escalate tensions in Kaliningrad, framing the factory as a “legitimate military target” to test NATO’s Article 5 resolve.
For now, the deal is a win for both sides: Estonia secures its artillery needs without relying on Germany, and Turkey gains a foothold in NATO’s most vulnerable flank. But the real question is whether this is the start of a broader realignment—or just the first move in a high-stakes game of geopolitical chess.
The Takeaway: Your Move, Brussels
Europe’s defense industrial base is at a crossroads. The ARCA factory in Estonia isn’t just about shells—it’s about who controls the future of NATO’s supply chains. With the EU still debating its next defense fund and member states squabbling over burden-sharing, Turkey is quietly filling the gap. The question for European policymakers isn’t whether to compete with Ankara, but how to integrate its growing influence without ceding strategic autonomy.
So here’s the conversation starter: If Estonia’s factory becomes a model for the Baltics, will Sweden and Finland follow suit? And if they do, will Brussels finally wake up to the fact that the arms race isn’t just about tanks and jets—it’s about who writes the rules of the next century?
