Direct proof of conflict supply
On 3 February 2026, the Government Offices of Sweden announced that Sweden and Denmark were jointly procuring TRIDON Mk2 air-defense systems for donation to Ukraine. The same release states that the Ukraine-bound systems include spare parts and large amounts of ammunition, including advanced pre-fragmented, programmable, proximity-fused 3P ammunition.
The public evidence supports procurement and planned transfer for Ukraine in the 2014 Russia-Ukraine War. It does not, by itself, document Ukrainian battlefield firing of the ammunition.

Narrative
The 3P ammunition entered the cataloged conflict context as part of a short-range air-defense package rather than as a separately observed battlefield munition. Sweden described TRIDON Mk2 as a Swedish-made mobile anti-aircraft artillery system produced by BAE Systems Bofors, using a newly developed version of the Bofors 40 mm gun. The Ukraine package paired the gun systems with command-and-control upgrades, Saab Giraffe 1X radars, spare parts, and 3P ammunition.
BAE Systems describes TRIDON Mk2 as a self-propelled, remotely controlled 40 mm anti-aircraft gun for aerial threats including drones, cruise missiles, and aircraft, with a secondary ground-target capability. BAE's 3P material describes the ammunition family as programmable all-target ammunition with six function modes, placing the Ukraine-linked round in the same air-defense and multi-target ammunition family.
