NATO allies to help Finland build air bases for F-35
NATO member countries will contribute to the construction of new air bases where F-35 fighters will be stationed, Yle reported on 4 September.
The NATO Investment Committee will decide the size of each country’s contribution. Defence Properties CEO Matias Warsta expressed hope that the funding will reach over 100 million euros ($116 mn)
“I hope that we reach a three-digit figure, over one hundred million euros,” Warsta said, emphasizing this was his personal assessment.
Finland’s Ministry of Defence declined to provide forecasts on the amount other NATO countries might contribute.
According to Yle’s calculations, the potential 100 million euros ($116 mn) would represent one-fifth of the construction program worth approximately half a billion euros. The plan includes building shelters, maintenance facilities, and storage for new F-35 fighters in Rovaniemi, Siilinjärvi, and Tikkakoski.
NATO approved almost the entire Finnish F-35 infrastructure construction program as eligible for funding earlier this spring. The first F-35 fighters are expected to arrive at the Rovaniemi air base in late 2026, where construction work has already begun.
Finland has ordered 64 new F-35s from Lockheed Martin to replace aging F/A-18 Hornets.
Finland receives NATO co-financing for the first time
NATO provides funding through its investment program when a project is deemed to generate capabilities for the entire defense alliance and exceed national needs. According to Warsta, access to NATO co-financing was not guaranteed when construction began.
“This is an educated expert assessment. But the sum could be larger or smaller,” Warsta said.
Special adviser Arjo Kaarre from the Ministry of Defence noted that determining which aspects of fighter base equipment exceed Finland’s needs is not straightforward.
“It’s a matter of negotiation and partly interpretative,” Kaarre said.
Each NATO country’s payment share is determined in the same proportion as membership fees. Kaarre indicated the first funding decisions will likely be made next year.
Finland has not previously received NATO co-financing for its construction projects.
Manufacturer sets new requirements mid-construction
The first F-35 fighters will arrive at the Lapland Squadron in Rovaniemi in late 2026. Construction work continues at the site.
Cost estimates for the Rovaniemi base have increased from 150 million to 200 million euros (from $174 mn to $232 mn), though Warsta said they remain within agreed frameworks.
“In addition to rising construction costs, the equipment manufacturer (Lockheed Martin) has also set additional requirements for the work,” Warsta explained.
Both Lockheed Martin and the US administration have imposed strict security requirements and regularly inspect compliance.
Construction at Rovaniemi includes underground spaces for fighters and information systems, a 3,000 square meter storage facility for spare parts, maintenance facilities, and training facilities with simulators.
The airfield will see increased use as training activities with NATO allies intensify. In real situations, allied fighters could also rely on Finnish bases.
