Why frozen meals strain Second World War logistics

Would modern frozen meals improve morale for Second World War American troops?

They could help aboard ships with refrigeration, but a general wartime frozen-food supply chain would be impractical.

The main difficulty is the uninterrupted cold chain behind a frozen meal. Second World War logistics could not reliably keep large quantities frozen through every transport and storage stage, making spoilage a serious risk. Ships with existing refrigerated spaces could carry selected foods such as frozen pizza and use them for morale. Land forces would still depend on tinned supplies because maintaining the required infrastructure across a theater would be an avoidable burden.
