Why logistics would limit a Soviet M-class AA cruiser

Would an M-class anti-aircraft cruiser conversion be more useful, especially in Soviet Lend-Lease service?

The conversion could be useful, but Soviet logistics and infrastructure would still sharply limit how effectively the cruiser could operate.

The hypothetical converts the British M class into anti-aircraft cruisers and asks whether a Soviet Lend-Lease example would see more use. The panel expects the conversion to improve utility in principle. Soviet naval forces nevertheless struggled to sustain large warships because bases, repair facilities, and supply systems were limited. Destroyers and gunboats were easier to employ within that infrastructure than a specialized cruiser. Better armament cannot overcome a support network unable to keep the ship ready and supplied.
