The Ukrainian deep-strike campaign

Summary

Alongside the fighting on the line, Ukraine has developed and expanded a campaign against targets deep inside Russian-held territory and inside Russia itself. Its most consequential component is domestically produced long-range one-way attack drones, which removed Ukraine's dependence on partner-supplied missiles and on the political permissions attached to them. Target classes have included oil refining and export infrastructure, military airfields hosting the aircraft used in the strike campaign against Ukraine, ammunition and fuel storage, and the Black Sea Fleet. The campaign's political dimension is inseparable from its military one: for much of the war, partner-supplied weapons carried restrictions on use inside Russia which were relaxed in stages, and the growth of the domestic drone programme was in part a response to that constraint.

Why it matters

This campaign is Ukraine's principal means of imposing cost on Russia away from a front where it is at a manpower disadvantage, and it is the clearest case in the war of a smaller power building an independent strategic capability rather than waiting for one to be supplied. It connects directly to the module's economic content — refining and export capacity is where Russian war revenue is generated — and to the naval campaign that reopened Ukraine's own export corridor. It is also the sharpest test of escalation management by Ukraine's partners.

Stated objectives

What the participants say. Each entry cites where the position was stated; Vigil records that it was made, not that it is true.

• Ukraine states that its strikes are directed at military and military-economic targets contributing to the war against it, and asserts a right to strike such targets on Russian territory.

Assessed objectives

Vigil's reading, graded. Kept structurally apart from stated positions so an assessment can never be published as someone's declared aim.

• The concentration on refining and export infrastructure indicates a revenue-denial objective rather than a fuel-denial one: Russia's constraint is what it earns, not what it can burn.

  Confidence: ModerateSources: ISW campaign assessments · Public market and insurance data

• The domestic long-range drone programme was accelerated substantially to escape the political conditionality attached to supplied missiles, an assessment supported by the sequence of restriction changes and capability announcements.

Primary forces

• Unmanned Systems Forces Primary force · Confidence: Moderate · as of 2026-06

  The Unmanned Systems Forces are the institutional home of much of the long-range drone effort, though attribution of individual strikes is rarely official.

• Uncrewed Maritime Forces Primary force · Confidence: Moderate · as of 2025-12

  Naval drone units are the component that produced the campaign's clearest strategic result against the Black Sea Fleet.

Supporting & external

• Air Force Supporting force · Confidence: Moderate · as of 2026-06

  Delivery platform for supplied stand-off missiles, whose use has been governed by partner restrictions rather than by capability alone.

Reported participants

• Defence Intelligence of Ukraine (HUR/GUR) Reported participant · Confidence: Moderate · as of 2026-06

  Military intelligence is repeatedly reported as conducting deep operations including maritime drone attacks. Ukraine rarely confirms attribution, so the role is recorded as reported.

Affected parties

• Air Force Affected party · Confidence: Moderate · as of 2026-06

  Airfields hosting the aircraft used in strikes against Ukraine have been a recurring target class.

• Black Sea Fleet Affected party · Confidence: High · as of 2024-06

Outcome and present status

Continuing, with one decisive result and one unresolved one. The maritime component achieved a genuine strategic outcome: the Black Sea Fleet was pushed from the western Black Sea and Ukraine reopened a shipping corridor without a negotiated agreement. The campaign against refining and export infrastructure has imposed recurring disruption and repair costs without demonstrably changing Russian fiscal capacity, and whether cumulative effect or single-event effect is the right measure remains contested.

Observed adaptations

• Ukraine built an independent long-range strike capability domestically rather than continuing to depend on supplied missiles and the permissions attached to them.

• Russia dispersed aviation to airfields at greater depth and expanded point defences around refining and export infrastructure, which raised the cost of the campaign without ending it.

Political implications

Each expansion of range and target class has tested partner escalation tolerance, and the sequence of restriction changes is a record of where that tolerance actually sits.

Military implications

Demonstrates that a state without a strategic air force can build meaningful strategic reach from cheap uncrewed systems within a war.

Economic implications

Refining and export infrastructure is where Russian war revenue is generated, so disruption there is an attack on fiscal capacity rather than on battlefield supply.

Reference layers

What remains unknown

• Ukraine rarely confirms attribution for strikes inside Russia, so the attribution of individual actions to specific structures is reported rather than established.
• Damage assessments rest on satellite imagery and open-source analysis; Russian authorities minimise reported effects and Ukrainian claims maximise them.
• Russian refining throughput data has been published less completely since 2022, so the campaign's cumulative economic effect is estimated rather than measured.
• The module publishes no assessment of current defensive coverage of any target class, and nothing here should be read as such.

Readings the evidence also supports

• Falls in Russian refining output can be attributed to strikes, to sanctions on equipment and spare parts, or to deferred maintenance. All three operate simultaneously and published data does not separate them.
• The Black Sea Fleet's withdrawal from the western basin can be read as a result of the strike campaign or as a rational repositioning that would have happened anyway once the threat existed. The distinction matters for how much the campaign's success generalises to other target classes.

Listed because the record's own assessment is not the only one its sources permit — not as a hedge on the assessment above.
