Key takeaway

Ukraine is running a systematic SEAD campaign designed to outpace Russia's ability to repair its air defence network.

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.

Deep Analysis

In plain English

Air defence systems protect military targets from missiles and aircraft — think of them as a high-tech shield. Ukraine is not just trying to punch holes in that shield; it is trying to destroy the workshops that repair it. When a missile launcher is damaged, it normally goes to a repair facility to be returned to service. Ukraine has now struck the main facility in Crimea that fixes S-400 and Buk systems. The aim is to create a gap that stays open — because without a repair depot, destroyed launchers cannot be brought back. This is a deliberate long-term campaign to degrade Russia's ability to protect its military infrastructure across occupied territory, not a series of opportunistic strikes.

Deep Analysis

Synthesis

Ukraine's sequential targeting doctrine — launchers, then radars, then repair infrastructure — mirrors the industrial targeting logic embedded in the US Air Force's AirSea Battle concept for high-intensity peer conflict. Ukraine has become an inadvertent live test of whether disaggregated, attritable strike assets can degrade an integrated air defence network without stealth aircraft. The operational findings are being studied by multiple state actors — including the PLA — with implications for future SEAD doctrine well beyond this theatre.

Root Causes

Ukraine's SEAD campaign is structurally enabled by two factors not mentioned in the body. First, NATO ISR assets — including Rivet Joint electronic intelligence aircraft and commercial satellite tasking — provide targeting coordinates for fixed and semi-fixed installations that Ukrainian intelligence could not locate independently at scale. Second, the supply of Storm Shadow and SCALP-EG cruise missiles by the UK and France created a long-range precision strike capability that can reach deep into Crimea without Ukrainian aircraft overflying heavily defended airspace, removing the pilot-risk constraint that previously limited deep strike ambition.

Escalation

The Granit strike is qualitatively different from launcher attrition. A repair depot serves dozens of launcher systems across a theatre, with a reconstitution timeline measured in years rather than weeks. Russian replacement of Almaz-Antey repair capacity in Crimea would require either rebuilding the Sevastopol facility under persistent drone threat — itself a target — or establishing a new facility further from the front, extending response times and reducing operational availability across the entire southern theatre. Russia may retaliate by escalating strikes on Ukrainian defence-industrial facilities to impose a symmetric cost.

Meaning
Ukraine has shifted from reactive air defence to proactive suppression of enemy air defences — a doctrinal evolution with strategic, not merely tactical, implications for the war's trajectory.
Immediate · Assessed
Consequence
Granit's destruction extends Russian S-400 and Buk repair timelines from weeks to potentially months, degrading operational availability across Crimea and southern occupied oblasts simultaneously.
Medium term · Assessed
Risk
Russia may accelerate relocation of remaining irreplaceable repair infrastructure to mainland Russia, reducing vulnerability but extending forward response times and creating a logistics bottleneck for the entire southern theatre.
Medium term · Suggested
Opportunity
Systematic IADS degradation across Crimea creates persistent strike corridors for Storm Shadow and ATACMS against naval and logistics targets currently shielded by layered coverage.
Medium term · Assessed
Precedent
Ukraine's sequential launcher-then-repair-facility targeting establishes the first documented attritable-drone SEAD template against a peer-level integrated air defence network, with implications for future NATO doctrine.

Source Landscape

This story draws on mixed-leaning sources from Ukraine

Ukraine

Primary parallel: Israel's Operation Mole Cricket 19 (June 1982) remains the most successful SEAD operation of the modern era — systematically destroying Syria's SA-6 network in the Bekaa Valley using electronic warfare, drones as decoys, and precision strikes, enabling unchallenged Israeli air operations for years thereafter and validating the sequential launcher-then-suppression doctrine.

Counter-parallel: NATO's Allied Force SEAD campaign over Serbia (1999) initially struggled to destroy mobile SAM systems because Serbian operators dispersed and concealed them effectively; Russia has studied this lesson and employs analogous survivability tactics, complicating Ukraine's targeting of mobile launchers relative to the fixed Granit repair infrastructure.

Why it’s relevant now

The Israeli 1982 model is the closest historical precedent for Ukraine's sequential logic — destroy launchers, then destroy repair infrastructure — and it produced durable air superiority. Russia's greater dispersal discipline and strategic depth make a comparable outcome significantly harder to achieve, but the targeting logic is structurally sound.

An S-400 battalion set costs approximately $500 million to manufacture and field; S-300 batteries cost $100–$200 million each. Destroying over 20 systems in 15 days — even weighted toward older S-300 variants — implies material attrition in the range of $2–$4 billion concentrated in a single fortnight.

Almaz-Antey's production capacity for S-400-class systems is estimated at four to six systems annually. At the observed destruction rate, battlefield losses are outpacing replacement production capacity by a factor of roughly ten to one. Granit's role as the primary forward repair node for Crimea and the southern oblasts means that even if production continues at full rate, forward operational availability will decline faster than headline destruction figures suggest — the repair bottleneck compounds the production shortfall.

Consensus view: RUSI's Justin Bronk assesses that degrading Russia's IADS is the single highest-leverage campaign Ukraine can execute, as each gap in coverage multiplies the effectiveness of every other strike asset — Storm Shadow and ATACMS strikes that would previously have been intercepted can now reach high-value targets.

Counter-view: Analysts at the PLA Academy of Military Science in Beijing have reportedly studied Ukraine's SEAD campaign as a potential model for suppressing Taiwan's Patriot PAC-3 and Tien Kung network, a finding that AEI's Marc Thiessen and CSIS's Tom Karako have flagged publicly as a significant intelligence concern — Russia is inadvertently generating tactical doctrine that adversaries of the West are absorbing.

Key tension: Whether Ukraine's Storm Shadow and ATACMS stocks — not publicly disclosed but estimated at fewer than 400 combined — are sufficient to sustain the campaign tempo needed to prevent Russian IADS reconstitution through mid-2026 without further Western transfers.

Update #6 · Ukraine sends negotiators as front reverses

Different Perspectives

NATO eastern flank (B9 + Nordics)

The B9+Nordic Bucharest joint statement on 13 May reaffirmed Ukraine's sovereignty within internationally recognised borders and backed NATO eastern flank reinforcement; the summit accepted Zelenskyy's bilateral drone deal proposal as a structural alternative to the stalled US export approval pathway, treating it as a European defence architecture question rather than aid delivery.

IAEA / Rafael Grossi

Grossi is still negotiating a sixth ZNPP repair ceasefire with no agreement after 50 days of 750 kV line disconnection; the 3 May ERCL drone strike that destroyed environmental monitoring equipment represents a qualitative escalation in infrastructure degradation that the IAEA has documented but cannot compel either party to halt.

Péter Magyar / Hungary

Magyar's incoming foreign minister pledged on 12 May that Hungary will stop abusing EU veto rights; the pledge is a statement of intent rather than a binding legal commitment, and Magyar's MEPs voted against the €90 billion loan as recently as April, while a planned referendum on Ukraine's EU accession preserves a downstream blocking lever.

EU Council and European Commission

The Magyar cabinet formation on 12 May removes the Hungary veto that had blocked the €9.1 billion first tranche since February; the Commission is now coordinating the three-document disbursement package for an early-June vote. The structural blocker is gone; the disbursement question is now scheduling, not politics.

Donald Trump / White House

Trump announced a 9-11 May three-day ceasefire with a 1,000-for-1,000 prisoner exchange attached, then called peace 'getting very close' on 11-13 May while Russia's 800-drone barrage was under way; his public framing adopted Russian diplomatic language without securing any Russian operational concession or verifying the exchange was agreed.

Vladimir Putin / Kremlin

Putin told reporters on 9 May the war is 'coming to an end' while Peskov confirmed on 13 May that territorial demands are unchanged and Russia requires full Ukrainian withdrawal from all four annexed regions; the verbal accommodation costs Moscow nothing and conditions any summit on a pre-finalised treaty Kyiv cannot accept.
