 Crimean bridge is under threat. Expert outlines purpose of Ukrainian strike on Zankhoi. The Ukrainian strike on the airfield in occupied Zankhoi is a preparation for a large-scale attack on Crimea, and the subsequent strike on the Crimean bridge stated the Ukrainian expert Oleksandr Musienko in a commentary to RBC Ukraine. According to the expert, the goal is to destroy the enemy's air defense systems and open the northern gates of Crimea. The expert clarified that globally this should be interpreted as preparation for a large-scale attack on Crimea to disable particularly important and valuable objects for the enemy. I would even say that it is a preparation for an attack on the Crimean bridge. This algorithm involves disabling air defense systems and radars after which more damaging strikes are delivered to the enemy. So I would say that this is the main goal, Musienko said. A guest on Russian state TV has decried Ukraine's attack on a large Russian airfield in annexed Crimea that is reported to have killed up to 30 Russian personnel and wounded a further 80 people. Russian military expert Vladislav Shurigin said during an appearance on full contact with Vladimir Solovyov that the strike served as a rehearsal for a future Ukrainian attack on the Kersh Strait Bridge which connects Russia with the Crimean Peninsula. Host Solovyov is one of the most prominent figures in Kremlin-backed media. The Kersh Strait Bridge serves as a key supply route for Russia's forces and is Moscow's sole land link with Crimea, the Black Sea Peninsula annexed by Russian President Vladimir Putin in 2014. Shurigin said that the attack on the Russian navy's Zankoi airbase, which is reported to house the 39th helicopter regiment of the 27th mixed aviation division, served as target practice for a future Ukrainian strike on the Kersh Strait Bridge, also known as the Crimean Bridge. Shurigin claimed Kiev used 780 ACMS missiles in the attack on Wednesday and that the strike was a rehearsal to test how Russia's air defence works. He said an attack on the Kersh Bridge will most likely take place on May 7, although he did not elaborate on why he highlighted that particular date.
