Background: The Lift in Restrictions

For most of the first two years of war, Ukraine's Western partners imposed significant restrictions on using supplied weapons to strike targets inside Russia proper. Ukraine was limited to firing HIMARS, MLRS, artillery, and air-launched weapons only against targets in occupied Ukraine. This reflected fears of Russian escalation (including nuclear threats) that constrained Western decision-making.

Key turning points in restrictions:

• November 2023: UK/France authorise Storm Shadow/SCALP use against military targets in occupied Crimea
• April 2024: US authorises limited ATACMS use for cross-border suppression of Russian artillery firing into Kharkiv
• September 2024: US, UK, and France authorise use of supplied weapons against military targets inside Russia proper — long-range ATACMS and Storm Shadow cleared
• Late 2024: Several allies remove distance restrictions entirely for HIMARS GMLRS rockets
• 2025: Ukraine begins large-scale use of domestically produced Palyanitsya and long-range drone swarms against Russian territory

Russia's threatened nuclear response to each Western lifting of restrictions failed to materialize, progressively eroding the credibility of nuclear deterrence as a constraint on Ukrainian offensive capability.

Ukraine's Deep Strike Arsenal (March 2026)

ATACMS: America's Contribution

Army Tactical Missile System (ATACMS) has been the most significant Western deep strike contribution. The Biden administration's September 2024 decision to authorize use against Russia proper was a pivotal policy shift.

ATACMS has been used against:

• Russian military airfields in Crimea (Saki, Belbek)
• Logistics hubs in Zaporizhzhia and Luhansk oblasts
• Command posts and ammunition depots 150–450km from the front
• Air defense radars in Crimea and eastern Russia

The longer-range PrSM (Precision Strike Missile), with range up to 499km, was delivered to Ukraine in limited numbers in late 2024. This extends ATACMS reach to cover virtually all of Crimea as well as key logistics nodes in Rostov oblast and the eastern Black Sea region.

Supply constraints: The US Army has its own ATACMS stocks that it must protect for Indo-Pacific contingencies. This has kept deliveries limited — sufficient for targeted deep strikes but not industrial-scale bombardment of Russian rear areas.

Storm Shadow / SCALP-EG: European Cruise Missiles

The UK-supplied Storm Shadow and French-supplied SCALP-EG are functionally identical air-launched cruise missiles (inherited from a joint development programme). They have shaped the deep strike campaign significantly.

Key features enabling operational value:

• BROACH (Bomb Royal Ordnance Augmented Charge) tandem warhead for hardened target penetration — effective against hardened bunkers, underground command centres
• Terrain-hugging autonomous navigation with terminal optical guidance — relatively resistant to jamming
• Air-launched from Su-24M Fencer and Su-27 Flanker modified to carry the Western missile
• Radar cross-section low enough to complicate S-300/S-400 engagement

Confirmed notable strikes: Crimea submarine base (September 2023), multiple Black Sea Fleet ships, Russian naval logistics hub at Sevastopol, command facility at Cape Chersones.

Indigenous Ukrainian Systems

Ukraine's most consequential long-term development is the maturation of its domestic deep strike capability — weapons that are not subject to Western delivery constraints or political conditions.

Palyanitsya Cruise Missile

Officially confirmed by President Zelensky in September 2024, the Palyanitsya is Ukraine's first publicly announced indigenous cruise missile. Key reported characteristics:

• Range: approximately 700km
• Jet-propelled (turbojet engine)
• GPS + inertial + possibly optical terminal guidance
• Based on Ukrainian design derived from pre-war R-360 Neptune development experience
• Production ramping at Ukrainian defense plants

Neptune Extended-Range

Ukraine has also developed an extended-range version of the Neptune anti-ship missile for land-attack missions. Adapted from the original 280km design, the land-attack variant reaches approximately 400–450km with a modified warhead optimized for ground targets.

Long-Range Strike Drones

Ukraine operates multiple indigenously produced long-range drone designs capable of striking deep into Russian territory:

• Multiple drone types with 800–1,500km operational range
• Used in swarm attacks against Russian airfields, oil refineries, power plants
• Strikingly accurate: repeated successful strikes on oil refineries as far as Saratov and Tatarstan
• Production scaled to hundreds per month

Maritime and Long-Range Drone Strikes

Ukraine's sea drone program has been a breakout success, transforming the Black Sea military balance:

• Sea Baby and Magura V5 surface drones have sunk or seriously damaged 17+ Russian naval vessels since 2023
• Russia evacuated the bulk of its Black Sea Fleet from Sevastopol to Novorossiysk by mid-2024
• Ukraine regained effective use of western Black Sea shipping lanes, enabling grain and commercial exports
• Sea drone strikes on the Kerch Strait bridge have degraded Russia's Crimea logistics

Ukraine is developing larger sea drone variants with longer range (potentially reaching Novorossiysk from Ukrainian-controlled waters) and heavier payloads, extending the maritime threat further.

Target Set and Operational Impact

Ukraine's deep strike campaign has targeted:

• Airfields: Crimea-based airfields hosting Tu-22M bombers and Su-35s; Rostov-on-Don area airfields used for glide bomb launches
• Ammunition depots: Explosions at Russian ammunition storage sites in Crimea, Belgorod, Kursk, Voronezh (captured on Russian civilian social media)
• Oil infrastructure: Refineries at Ryazan, Saratov, Novoshakhtinsk — cumulative 10–15% reduction in Russian refinery capacity by mid-2025
• Logistics hubs: Rail junctions and fuel/supply depots in Luhansk, Zaporizhzhia, Mariupol areas
• Naval base: Sevastopol naval infrastructure — forced relocation of Black Sea Fleet
• EW and radar sites: Russian early warning radar on Kola Peninsula struck by Ukrainian drones (late 2024) in a dramatic range demonstration

Constraints

Ukraine's deep strike capability still faces significant limitations:

• Volume: Ukraine cannot replicate the industrial-scale bombardment Russia inflicts on Ukraine. Hundreds or low-thousands of missiles per year vs. Russia's tens of thousands.
• Aircraft dependency for Storm Shadow/SCALP: Ukraine has a limited and aging fleet of Su-24M and Su-27 capable of delivering these missiles; aircraft losses are not easily replaced
• Warhead size: Ukrainian long-range drones carry 30–50kg warheads — sufficient for soft targets and oil infrastructure but limited against hardened military targets
• Russian air defenses improving: Russia has deployed more S-400 and S-500 batteries and improved radar coverage to counter Ukrainian deep strikes
• Political constraints remain on some systems: Germany has not delivered Taurus cruise missiles (range 500km, BROACH-equivalent warhead) despite Ukraine's repeated requests; this remains a gap in Ukrainian capability

Assessment

Ukraine's deep strike capability has evolved from zero to genuinely threatening in three years. Key achievements:

• Black Sea Fleet effectively neutralized — an asymmetric victory achieved primarily through Ukrainian domestic innovation
• Russian forward airfields in Crimea made operationally risky — bombers relocated further from Ukraine
• Russian oil refinery output reduced, increasing domestic fuel costs
• Ammunition depots pushed further from the front, lengthening Russian resupply chains
• Psychological impact on Russian civilian population from drone strikes reaching Moscow suburbs

The trajectory is positive: Ukraine's indigenous production is growing, restrictions on Western systems have largely lifted, and new systems (PrSM, Palyanitsya) are extending range further. However, the volume gap with Russia's strike capacity remains enormous — Ukraine is disrupting Russian operations at the margins rather than fundamentally degrading Russia's military-industrial system.
