Between 1 and 15 March, Ukrainian forces struck over 20 Russian air defence targets across Crimea, Kherson, Luhansk, and Zaporizhzhia oblasts 1. The systems destroyed span Russia's full layered defence architecture: S-400, S-300, S-300V, Buk-M3, Buk-M1, Tor, and Pantsir-S1 launchers — from long-range strategic interceptors down to short-range point defence. Eight radar types were also hit, including the Nebo-U early-warning system and Sopka-2 coastal surveillance radar.
The target selection follows a doctrinal logic. Russia's integrated air defence system depends on overlapping coverage: long-range S-400s protect against cruise missiles and aircraft, medium-range Buks fill the gap beneath them, and short-range Tor and Pantsir systems SHIELD individual sites from drones and precision munitions. Destroying systems across all three tiers simultaneously prevents Russia from compensating for losses at one layer with coverage from another. The radar strikes compound the effect — without early-warning sensors, surviving launchers operate with degraded reaction time and reduced engagement range.
This campaign fits within a broader interdiction sequence targeting Russia's ability to produce, field, and repair air defence systems. On 10 March, Storm Shadow cruise missiles struck the Kremniy El microelectronics plant in Bryansk, one of Russia's largest manufacturers of semiconductor components for Iskander guidance and Pantsir air defence systems . The March field strikes followed that production hit with direct destruction of deployed launchers. The Ukrainian MoD stated that the destruction 'creates a gap in the enemy's air defence, opening space for our missile strikes and air operations' 2.
The operational consequence is visible in what Ukraine can now reach. The sustained strikes against southern Russia's fuel logistics — the Labinsk oil depot , Tikhoretsk pumping station , Afipsky refinery , and Port Kavkaz — all hit in the first half of March — depend on degraded Russian air defence coverage along those flight paths. Russian drone sorties have not fallen below 6,000 per day since mid-March , nor guided aerial bomb volumes below 200, but each destroyed S-400 battery that goes unrepaired widens the corridor through which Ukrainian long-range strikes can pass. The question is whether Russia's replacement rate — constrained by the Kremniy El damage and by SIPRI data showing Russian arms exports fell 64% over the most recent five-year period — can keep pace with destruction in the field.
