Fighters of the Armed Forces of Ukraine's Unmanned Systems Forces have confirmed the destruction of an ammunition depot at the 758th Material and Technical Supply Center of the Russian Black Sea Fleet in temporarily occupied Crimea. The facility is located in Sevastopol — in the areas of Tsukrovaya Golovka and Shabalina Street — and serves as a key hub through which the fleet receives fuel, ammunition, and supplies.

What is the 758th Material and Technical Supply Center and why is it important

This is not a peripheral warehouse. The 758th MTSC is the logistical core of the Black Sea Fleet: without its uninterrupted operation, the fleet physically cannot maintain combat activity in the south. The partisan intelligence network "Atesh," which monitors the facility, has documented that following a series of previous strikes, equipment has been withdrawn from the base — only isolated non-functional vehicles remain.

"Our agents have recorded an almost complete absence of equipment at the base. Individual vehicles appear to be non-operational. This is a clear sign of the occupiers' deficit: equipment is being transferred across all of Crimea to protect it from strikes by the Defense Forces."

The dispersal of equipment across the peninsula is a forced reaction that itself reduces operational efficiency: centralized supply is replaced by chaotic resource redistribution.

Why a strike on the MTSC is an indicator of air defense status

Military serviceman of "Raid" and weapons expert at Defense Express Ivan Kyryshevsky emphasizes: the fact that unmanned systems reached the facility in Sevastopol is itself telling. A strike against a well-known, fixed target in the heart of an occupied city becomes possible only when the enemy's air defense system degrades. This confirms the cumulative effect of previous strikes against Crimean air defenses.

Context matters: in spring 2024, following a series of targeted attacks by Ukrainian marine drones, Russia withdrew the main part of the Black Sea Fleet from Crimea to Novorossiysk. However, the logistical infrastructure — particularly the 758th MTSC — remained in Sevastopol, continuing to supply occupation units in the south.

Tactical logic: a chain, not an isolated strike

Strikes against the Black Sea Fleet's logistics fit into a strategy that Ukrainian forces are applying systematically:

• Fuel, ammunition, supplies — three flows that pass through the MTSC. Interrupting any of them slows the pace of operations in the south.
• Equipment dispersal — a forced enemy response that increases their logistical burden without any gain.
• Air defense degradation — each successful strike against a protected target deep in Crimea confirms that the "umbrella" over the fleet is becoming increasingly porous.

According to the ISW, systematic destruction of logistical hubs and air defense nodes in Crimea is gradually restricting the operational space for Russian forces in the maritime and southern directions.

Consequences and open questions

The 758th MTSC has been struck before — and continued to function. The current strike on the ammunition depot confirms that the facility remains a priority target, not a one-off episode. If Ukrainian forces maintain the capability to systematically attack the fleet's logistical infrastructure directly in Sevastopol — Russia will either have to completely withdraw the remaining fleet further from Crimea, or relocate the MTSC deep into Russia, which would significantly lengthen and increase the cost of the supply chain for occupation forces in the south.
