STOCKHOLM, Feb 3 (Reuters) – Sweden and Denmark will jointly procure and supply Ukraine ​with air defence systems worth 2.6 ‌billion Swedish crowns ($290 million) to help it ward off ‌Russian attacks, the countries’ defence ministers said on Tuesday.

Sweden will fund 2.1 billion crowns of the purchase of Tridon air defence ⁠systems, developed by ‌BAE Systems Bofors, the Swedish arm of the defence material group, ‍while Denmark will contribute about 500 million crowns, Swedish Defence Minister Pal Jonson said.

“This means that ​Ukraine can develop an air defence battalion ‌if they so wish,” he told a joint press conference in Gothenburg, Sweden, with his Danish counterpart Troels Lund Poulsen.

“The purchase doesn’t just support Ukraine on the battlefield ⁠with more material, but ​also strengthens our production ​capacity in Sweden.”

Sweden and Denmark have for years been some of the staunchest ‍backers of ⁠Ukraine, supplying military and humanitarian support since the early days of Russia’s invasion ⁠of its neighbour.
