Japan’s defense ministry is requesting a nearly 12% budget increase that includes two warships with advanced radar and long-range cruise missiles as it further fortifies the nation’s military in the face of North Korean threats and Chinese military advancement.
The record 7.7 trillion yen ($52.5 billion) request for the 2024 fiscal year marks the second year of a rapid five-year military buildup under a new security strategy Prime Minister Fumio Kishida’s government adopted in December. It focuses on reinforcing strike capability in a break from Japan’s postwar principle of having a military only for self-defense.
Under the five-year plan, Japan plans to spend 43 trillion yen ($315 billion) through 2027 to nearly double its annual spending to around 10 trillion yen ($68 billion), making Japan the world’s third-biggest spender after the United States and China. How to finance and justify the growing military spending is uncertain in a country with steeply declining births and increasing costs of caring for its aged population.
Submarines can’t win a war at sea alone, and we have ASW capable aircraft flying constantly for surveillance against them. We’ve been doing it for more than half a century now.
The reason aircraft carriers became ubiquitous was because aircraft are the most effective means of deploying weaponry. That hasn’t changed. They can also project power inland as well as engaging surface and sub surface craft.
Nothing about warfare technology has been drastically altered enough for submarines to be the primary fighting force. They have a job that they’re damn good at, but aircraft are more multirole and far quicker.
Surveillance, recon and range of weapons has drastically changed. Satellites have the capability to identify a surface fleet and long range weapons are now able to be fired from long distances, find and hit their targets.
I think a couple submarines can effectively negate a carrier task force by just forcing the task force to keep their distance by the threat of a missile launch coming from a patch of seemingly empty see. Any surface ship hunting them is at risk of suddenly becoming the hunted themselves by the submarine or by any land based defense system that are in range.
We employ helicopters and fixed wing to monitor, hunt, and if need be, destroy submarines. Destroyers are also competent submarine hunters.
Nothing about what you’ve said is inherently “false”, but you’re not accounting for the ways we fight submarines (mostly aircraft.) Cruise missiles and boomer submarines are a threat, but the technology has been around for long enough that if subs were to become some super weapon because of it we’d have seen it by now. They serve their purpose well, and we have more than a few ways to defend against them (once again, mostly the aircraft from those carriers you insist on pretending are going the way of the battleship.)
Go look up the history of Naval ASW, from the VPB squadrons that flew Pioneers and Catalina’s in WW2 to the modern platforms that VP and HSM squadrons use. It’s a really interesting progression of technology.
