Venture capital surges into Europe’s Iron Dome-style air defense startups

Governments are seeking cost-effective solutions against mass drone attacks, and venture capital investors are increasing their backing of Europe’s “Iron Dome”-style air defense technologies.

Leading investors such as Lakestar, Lux Capital, and Accel have supported the latest funding rounds of startups including Germany’s Tytan Technologies and UK-based Cambridge Aerospace.

According to sources close to the fundraising process cited by the Financial Times (FT), Cambridge Aerospace completed a $100 million round led by Spark Capital, which valued the company at around $400 million.

Tytan has so far raised more than €15 million, while Sweden’s Nordic Air Defence recently secured $4.4 million in early-stage funding.

Russia’s ongoing drone campaign—deploying hundreds of Iranian-designed Shahed drones in each attack—has heightened the urgency among governments to strengthen their air defense capabilities.

Meanwhile, US President Donald Trump’s plans for a “Golden Dome,” inspired by Israel’s Iron Dome short-range defense system, have sparked additional investor interest in how European countries can adapt their defense capacities to diverse threats.

Max Enders, head of government affairs and business development at Tytan, said Europe faces “a massive talent gap.” He added: “The old Western paradigm of firing very expensive missiles at cheap drones that constantly innovate is failing in Ukraine.”

Enders explained that Tytan plans to combine off-the-shelf hardware and 3D-printed components with “smart AI capable of detecting, classifying, and intercepting targets.” The goal, he said, is always to be cheaper than what is being shot down.

The startup’s first product, the Tytan Interceptor, is designed to operate on the front line of defense and can reach speeds above 250 km/h.

Cambridge Aerospace CEO Steven Barrett declined to comment on recent fundraising efforts but confirmed that the company is holding “extensive discussions” with potential government clients regarding its Skyhammer interceptor system, which targets large drones and cruise missiles.

Skyhammer can reach speeds of 700 km/h and has a range of 30 km. A more advanced product, Starhammer, still under development, will be rocket-powered.

The company, chaired by former Conservative defense secretary Grant Shapps, plans to produce rocket motors in-house. Barrett emphasized their focus on ensuring production relies primarily on the European supply chain.

He added that Cambridge has gone further by identifying costly and less secure components in interceptors—such as propulsion systems and radar—and bringing their production in-house.

Both companies acknowledged that scaling up production in the coming months will be a crucial test.

Despite recent moves toward ending the conflict in Ukraine, Enders stressed that the business case for better air defense systems remains strong.

“Our work is not dependent on the Ukraine conflict,” he said, adding that the war has demonstrated that “systems are inadequate in defending against drones and air threats.”
