By late 1948 during the Chinese Civil War, the monthly production of the Arsenal was 3,000 Mauser Type 24 rifles, 300 7.92 mm ZB 26 light machine guns, 60 7.92 mm Type 24 Maxim water-cooled machine guns (MG08/30), 8 75 mm field guns, and 60,000 grenades, 15,000 mortar rounds, 7,000 rounds of artillery shells, swords, bayonets and small arms ammunition. But near the end small arms 7.92 mm ammunition production was down. Over 150,000 Red Army soldiers surrounded the city and it was necessary to air drop ingots of brass for the production of ammunition casings. Early in 1949 two Curtiss C-46 transports from Civil Air Transport flown by American pilots landed on an improvised runway delivering dynamite and blasting caps to destroy the steel mills and arsenal. However, when the city fell in the spring the arsenal fell to Communist hands in good shape, providing a solid base for their armaments industry.
