Less than two years ago, Sweden’s BAE Systems Bofors announced it was developing a new 40mm short-range air defence system using internal research and development funding, calling it the Tridon Mk2.
BAE Systems Bofors has revealed to Shephard that the first example of the 40mm Tridon Mk2 underwent a series of trials in Sweden in mid-2025 to demonstrate its capabilities against a range of aerial threats including uncrewed aerial vehicles (UAVs).
The first technology demonstrator was completed last year. Late in 2024, BAE Systems Bofors signed an agreement with the Swedish Defence Material Administration to push the development of the Tridon Mk2 to meet the requirements of the Swedish Army for a mobile air defence system.
In February 2025, Sweden announced it would provide Ukraine with air defence systems worth SEK1.2
