Ukraine’s expanding long-range strike campaign against Russian oil infrastructure is exploiting overstretched Russian air defenses and significantly damaging Russian oil export capabilities. The Ukrainian General Staff reported on April 6 that Ukrainian forces struck the Sheskharis oil terminal near the port of Novorossiysk, Krasnodar Krai overnight on April 5 to 6, starting a large fire.[1] Geolocated footage published on April 6 shows fires at oil tanker berths at the port of Novorossiysk.[2] The Russian Ministry of Defense (MoD) acknowledged on April 6 that Ukrainian forces struck oil terminals in Novorossiysk.[3] Two industry sources told Reuters on April 6 that the fires covered the main pier belonging to Russian state-controlled petroleum company Transneft near three oil tanker berths.[4] NASA Fire Information for Resource Management System (FIRMS) data shows heat anomalies at the Sheskharis oil terminal starting on April 5.[5] Ukrainian Unmanned Systems Forces (USF) Commander Major Robert “Magyar” Brovdi reported that Ukrainian forces also struck the Admiral Makarov Admiral Grigorovich-class frigate in the port of Novorossiysk overnight.[6] Geolocated footage published on April 6 shows Ukrainian drones striking a Russian Admiral Grigorovich-class frigate in the port of Novorossiysk.[7]
Russia’s geographical size poses an enormous challenge to defend, especially with traditional air defense systems on which the Russians reportedly still rely to protect against Ukraine drone salvoes.[8] The need to cover vast areas with air defense systems is reportedly straining Russian air defenses, especially given Ukraine’s extensive strikes campaign against Russian air defense radars.[9]
Russian milbloggers continued to criticize the ineffectiveness of Russian air defense systems and highlight the impact of Ukrainian strikes. A Kremlin-affiliated Russian milblogger stated on April 6 that the constant Ukrainian strikes against Russian facilities are “stretching” Russian surface-to-air missile air defense forces “to the limit” and exhausting ammunition “at an accelerated rate” as Russia cannot simply produce “thousands” of missiles for Pantsir air defense systems “out of thin air.”[10] The milblogger stated that these limitations render ineffective Russian information space suggestions that Russia increase surface-to-air missile and air defense system production and encouraged Russian forces to adapt the Ukrainian emphasis on mobile fire groups, interceptor drones, and acoustic reconnaissance systems. Russian milbloggers also highlighted the resources consumed by repairing damage from Ukrainian strikes, daytime Ukrainian drone strikes exhausting Russian air defense, the sys
