Why is Japan building up its Navy?

[cnleio]

Finally navy is useless.

Junk of steel,waste of money

Of course not, Navy is the attack force. In the earth approximately 71% of the earth surface is ocean, even more if climate change has its way, there'r much more resources than on land and national interest in sea energy lines.

I just said only few rich nations can grow up a powerful Navy and invest billions of money to build many warships.Without a strong economy and advanced technology, u can not afford the Navy. Buying warship is useless for a Navy.

The oceans are free for sailing and exploring except the area near Andaman Islands as I know recently.

 

[BoQ77]

Japan could build their own AEGIS destroyer, AIP submarines, aircraft carrier, ...
Now they are building up ...

So they're not useless Navy ... do you agree ?

Traitor : as China claim, entire of South China Sea and East China Sea , not free as you said ...

How to get their approval to travel in those area ?

not really they have only good helicopter carriers but everything else is lagging behind, even to india now. Its funny how the biggest shipbuilders korea and japan suck at making war ships and subs

Designing commercial, cargo ships and warships is different.

If you excel in designing former, it is not necessary you will succeed in later.

China's first generation nuclear subs are outdated, but it can still beat the crap out of these short legged diesel subs.

U really have no idea about the capabilities of modern diesel subs,or how much quieter they are do u?Only disadvantage diesel subs have are endurance which isn't a factor in close range scenario like china-japan and they are noisy at speed which means they can't keep up with escorting carrier battlegroups?Since japan really doesn't have a CBG and one of the best ASW fleets in the world taht too is a moot point.In us naval exercises with its allies diesel subs are often the only thing that really troubles USN ,even its subs.

agree. The difference between SSN and diesel submarine is only their range of operation. Yet SSN has more noise than Diesel Submarine.

Why is Japan building up its Navy?

So the Japs can go whale hunting. Or whaling, but really not whaling because the whales didn't have to do anything but die. You don't call fox hunting foxing do you? Ot tiger hunting tigering.

So yea the Japs are using its Navy to protect the whale hunting ships.

Not whales, I think they will hunt Chinese warships or subs...

I don't think you are

Satire? Humour?
Do you know anything other than putting your square peg in a round hole?

Was that a compliment or insult

 

[Battle of Bach Dang River]

I don't think you are

Not satire or humour. It is real that everyone knows. I will look forward to see hunting...

 

[rockstar08]

can someone post the details of Japanese navy's ships and air crafts ?

How did you become a thinktank with logic like these? LOL. Beside the advantage of endurance and it's not a small advantage if your task is to escort AC whose operation and range is expand, it is also the speed. You have to understand that the job of submarine is vary depending on what mission it carries out to do. It can be attack, renaissance, and/or escort. If it an attack purpose, then nuclear sub is better equipped with more endurance, bigger to carry more missile, and high propulsion to power faster in operation. This is not a weak capabilities but very important for an attack sub. If it is renaissance mission, then it's debatable which is better. AIP sub is a little quieter but lack the ability to track down and keep up with a nuclear sub and nuclear AC because of the need to resurface eventually and go back to shore to refuel and recharge unlike a nuclear sub that can goes however long depending on the crews appetite. Lastly if the mission is to escort AC, then nuclear sub is more advantageous because AC's main purpose is to operate at sea, faraway from shore and home. If you can afford it, nuclear sub will win hand down.

japan does not need nuclear subs, they need just enough to cruise in the south china sea, the pacific and diesel subs are quiter.

Quieter with a tiny speed of 3 knots, so it can hardly cruise in the South China Sea.

That's best for ambush ... and hiding after attack

1. US is the best for nuclear sub
2. Germany and Japan is good for AIP sub ...

The easy job for Japan subs to aim to only Chinese targets which is short or medium range.

The harder for China to ready for multi national targets, some is long range targets.

That's why 20-30 subs are enough for Japan, but 100 subs still not enough for China.

So the more AIP subs for Japan, the more dangerous of their ambush. Strategy of them is 12 subs with 12 nuclear SLBM to danger enemy purpose.

The bigger quantity of China subs still lack of endurance for long range operation.
So almost useless for blue ocean strategy ...

I guess in near future, China would sell almost of their old-fashioned subs to Thailand, Pakistan, Bangladesh ...
