When the Imperial Japanese Navy attacked Pearl Harbor on December 7th, they concentrated on the US battleships and the airfields around the island of Oahu. The newest battleship was the USS West Virginia which had been commissioned in late 1923. The majority of the battleships had been commissioned before World War One or shortly thereafter. The Washington Naval Conference served to limit the construction of newer capital ships.
Looking at the front-line fighters that were destroyed in the attacks on the Wheeler and Hickham Air Fields, they were mainly Curtiss P-36 and P-40 fighters. Even though they were the US’s front-line fighters in the Pacific, they were outmatched by Mitsubishi A6M Zero.
Fortunately, Congress had passed the Two-Ocean Navy Act in July 1940. Enacted in response to the quick defeat of France, the act authorized an expansion of the US fleet by approximately 70% and appropriated $8.55 billion for construction. In today’s terms, that would be about $146 billion. The act provided for 8 new aircraft carriers, 7 new battleships, 15,000 aircraft, and over 100 destroyers among other ships. Ships to replace some of those lost at Pearl Harbor were already under construction by December 7th. The US, more importantly, had 13 active naval ship yards and at least seven private shipyards building warships. This was all done with a population that was literally 200 million people smaller.
One of my favorite daily reads is the blog of Cdr Salamander who is a retired US Navy officer. He has been quite critical of the US Navy’s combat preparedness, shipbuilding issues, and cost overruns. The commander has been thinking of things that it seems the US Navy’s planners are hoping won’t be discussed. Things such as another war in the Pacific. Unlike Pearl Harbor, it would probably start with an attack on Taiwan by the Chinese PLAN (Peoples Liberation Army Navy).
So imagine the Great Pacific War does break out. Unlike 1941 where we had a navy that had 790 ships, we have less than 300 currently. I will grant you that our current ships are more powerful, pound for pound, than the fleet was in 1941. Our current Arleigh Burke-class destroyers equipped with missiles could take on a WW2 battleship so long as it stayed out of gun range. But what happens when it shoots off all its missiles and needs to reload? Therein lies the problem. Vertical launch missiles currently have no way be being replenished or reloaded at sea.
Another issue is that replacing ships lost to enemy action in a timely manner would take years. We have four active US Navy shipyards plus a number of private ones. Nonetheless, collectively they have been averaging three ships per year for the last two decades. I sincerely doubt that we could spin up more shipyards or transform the private shipyards to make warships as quickly as was done in 1941. Even if we use small islands in the Pacific manned by Marines as stationary “battleships”, the GAO estimates it now takes 6.5 years to build a new amphibious warfare ship. What’s worse, 50% of the current ships are in a state of bad repair.
In conclusion, we should use this day as a reminder that we need a serious national conversation on naval and industrial readiness of this country if we are ever faced with another “Great Pacific War”. My fear is that somewhere along the way in the last 83 years we have forgotten the hard lessons taught by the attack on Pearl Harbor.
