Ukraine claims 27 vessels struck in Sea of Azov drone campaign as Russia halts Kerch Strait and Don-Azov Canal shipping, killing one Russian sailor

Summary

Ukraine's military claimed on July 11 to have struck 21 oil tankers, four tugboats, two dry cargo vessels and one specialized vessel in the Sea of Azov overnight, recording 73 confirmed hits, according to the Kyiv Independent citing Ukrainian General Staff. Russia responded by halting commercial navigation through the Kerch Strait and the Don-Azov Canal. Russian authorities separately confirmed four vessels were struck in Taganrog Bay, including a methanol tanker, with one sailor on a technical vessel killed. Rostov Region Governor Yuri Slyusar confirmed the death; Russian authorities said there was no methanol leak risk. Russia's air defenses claimed to have shot down 178 Ukrainian drones overnight across Kaluga, Rostov, Smolensk, Tver, Moscow, the Kuban, and Crimea. Russia simultaneously launched precision-weapon strikes on military-industrial targets in Kyiv and hit port infrastructure in Odessa, Chornomorske, and Izmail. The strikes are part of the broader Ukraine says its drones struck 35 Russian shadow-fleet ships in 96 hours, expanding the campaign to the Sea of Azov Azov Sea drone campaign.

The split

Ukraine's General Staff and Ukrainian outlets (Kyiv Independent, United24 Media) lead with the 27-vessel claim and Russia's decision to halt two key waterways, framing the campaign as a strategic success targeting Russia's energy logistics. Russian authorities confirmed only four vessels struck in Taganrog Bay, a much narrower count, and framed the overnight exchange within their own air-defense success of 178 drones downed. The War Zone and US defense outlets reported Ukraine's claimed totals but noted the figures are unverified. The gap between four vessels (Russia's confirmed) and 27+ vessels (Ukraine's claimed) is unresolved in the feed.

By the numbers

• 27, vessels Ukraine claims were struck: 21 oil tankers, 4 tugboats, 2 dry cargo and 1 specialized (Ukrainian General Staff via Kyiv Independent).
• 73, successful strike hits recorded by Ukraine's Unmanned Systems Forces in the overnight operation.
• 4, vessels Russia confirmed struck in Taganrog Bay, including a methanol tanker.
• 1, sailor killed on a technical vessel, per Rostov Region Governor Yuri Slyusar.
• 178, Ukrainian drones Russia claims its air defenses destroyed overnight.
• 2, waterways Russia halted: Kerch Strait and Don-Azov Canal commercial navigation.

Why it matters

Ukraine's drone campaign is systematically targeting the logistics chain supplying Russia's occupied territories via the Sea of Azov. Striking oil tankers and port infrastructure disrupts fuel supply to Crimea and rear-area operations. Russia's simultaneous strikes on Odessa's port infrastructure signal a parallel effort to suppress Ukraine's Black Sea export capacity, keeping both sides' rear-area supply lines under sustained pressure.

What to watch

• Ukrainian military confirmation or denial of the Taganrog Bay attack and the 48-vessel figure.
• Russia's port-infrastructure damage reports in Odessa, Chornomorske, and Izmail.
• Whether methanol or chemical cargo aboard the struck vessels creates an environmental hazard.
• How the sustained Azov Sea campaign affects Russia's fuel and supply logistics for Crimea.
