Ukraine’s domestically produced cruise missiles could deliver a significant blow to Russia’s air defense production capabilities, potentially enabling more effective long-range drone strikes against targets inside Russia, according to a December 12 report.
RUSI report findings
The Royal United Services Institute (RUSI) report, titled Disrupting Russian Air Defence Production: Reclaiming the Sky, identifies significant vulnerabilities in the production processes of several of Moscow’s key air defense systems.
The report recommends stricter export controls on critical Western machinery and sanctions on raw materials used in radar production, alongside prioritizing strikes on critical nodes within air defense production that are vulnerable to attack.
Pantsir system vulnerabilities
The report highlights the concentration of facilities manufacturing and assembling the Pantsir air defense system in Tula, Russia, located just 350 kilometers from the Ukrainian border.
While the area is heavily defended and Ukraine’s long-range strike drones have not caused significant damage so far, the report notes that as Ukraine’s stockpile of indigenous cruise missiles expands, the ability to reach and damage these targets improves.
Flamingo cruise missile
Ukraine is developing multiple cruise missiles, most notably the Flamingo, which President Zelensky described as the most successful missile Ukraine currently possesses.
The Flamingo has a claimed range of 3,000 kilometers (1,864 miles) and carries a 1,150-kilogram warhead.
Strategic implications
Russia uses the Pantsir system primarily for medium-range defense of critical infrastructure against long-range strike drones. Significant disruption to production would leave these sites more vulnerable to Ukraine’s long-range drones.
According to the report, Ukraine could saturate defenses on an approach to Tula before delivering a major strike to Pantsir production with cruise missiles, limiting Russia’s ability to defend other targets throughout 2026.
The report emphasizes these represent only a fraction of the vulnerabilities identified in Russia’s integrated air defense production.
Ukraine regularly uses domestically produced long-range drones to attack Russia’s oil infrastructure. Russia’s oil and gas production continues to face attacks as Kyiv works to cripple Moscow’s primary war funding source.
NATO implications
Beyond weakening Russia’s defenses against Ukrainian strikes, the report notes the added strategic benefit of leveling the playing field between Russia and NATO.
A systematic effort to exploit these vulnerabilities could disproportionately assist Ukraine in striking the economic backbone of the Russian war effort and reduce barriers to NATO airpower, potentially deterring future Russian aggression through denial.
Russian drone incursions into NATO airspace earlier this year exposed a significant weakness in NATO and European defenses: the lack of an effective method to counter Russia’s inexpensive, mass-produced drones.
S-400 and S-500 systems
The report also identifies vulnerabilities in the production processes of Russia’s most advanced long-range air defense systems, the S-400 and S-500.
Disruption to production of these systems could create significant challenges for Russia, as they form a critical component of the country’s weapons exports.
Air defense system purchases were among the key topics during Russian President Vladimir Putin’s recent visit to India.
