I did briefly look into how much the estimated $7B was as a proportion of GDP: 7B/2T = 0.35% of GDP, which feels like a lot. For 41 planes it'd be $170M per plane, which seems reasonable when compared to US bombers, but unclear for Russian ones, but my guess is it's not too far off. This source (https://www.france24.com/en/europe/20250601-ukraine-says-it-...) says $2B for the planes alone, but then you also had the airbases &c, and maybe a submarine base <https://newsukraine.rbc.ua/news/major-explosion-hits-russian...>. I'd still expect it to be a bit exaggerated for propaganda effects, but it does seem reasonable all in all.
