The U.S. and Japanese Pacific War equipment capabilities are far stronger than those of the Japanese.

From 1941 to 1945, Japan produced 17 aircraft carriers, 2 battleships, 9 cruisers, 63 destroyers, and 147 submarines. During the same period, the United States produced 131 aircraft carriers (including escort carriers), 10 battleships, 48 ??cruisers, 355 destroyers, 498 frigates, and 203 submarines.

Japan’s annual steel production is 5.8 million tons, and its annual ammunition production can reach 500,000 tons. The United States produces more than 33 million tons of steel, more than six times that of Japan. The number of American aircraft, 6.5 times the number of cannons, and 6.5 times the number of guns was that of Japan. The US military produced 40 billion artillery shells throughout World War II, and the total number was more than 500 times that of Japan.

The impact of the Pacific War between the United States and Japan:

After the Pacific War, the United States became a member of the world's anti-fascist allies. In June 1942, the Chinese and American governments signed the Sino-US Lend-Lease Act, under which the United States provided the Nationalist Government with a total of US$840 million in lease materials. In addition, the United States also provided a total of US$747 million in government loans to the National Government.

Through these loans, the United States imported a large amount of military supplies into China, and China exported a large amount of strategic minerals and agricultural products to the United States through barter to repay debts. The major export commodities of the Kuomintang-controlled areas were earmarked for barter debt repayment. From 1942 to 1945, 51.3% of mineral products were shipped to the United States, and the remaining 48.7% was shipped to the Soviet Union.
