On April 7, 1945, another precision bombing attack hit and destroyed most of the Mitsubishi Aircraft Engine Works.

On May 14 and 16, 1945, there were large air raids and widespread firebombing that targeted the Mitsubishi factories and other war industries, the arsenal, railroad freight yards, and the seaport.

Nagoya Castle, a national treasure which was being used as a military command post, was also hit during the May 14 raid and burned down.

Also during the winter of 1944 and spring of 1945 there were random single-bomber attacks that were used as psychological warfare to disrupt the city and damage the morale of the citizens.

The city produced between forty and fifty percent of Japan's combat aircraft and engines, including the Mitsubishi A6M Zero.
