Re: Ideal chinese carrier thread

I do not believe today's carriers are any harder to sink than WWII's battleships. Also, the weaponry used today is much more potent than what they had back in WWII.

Most of the losses of WWII era battleships were also due to the same causes (poor damage control, design defect / datedness, build quality). HMS Barham, a British Queen Elizabeth battleship, was lost to torpedoes because her torpedo protection scheme was obsolete. HMS Royal Oak had a defective torpedo protection scheme; the Revenge class battleships received external blisters containing “water excluding materials” in the form of closed metal tubes 8 and 9 inches in diameter, and wood pulp. In practise, this protection scheme was ineffective from the onset. The King George V battleships had a protection defect; the deck armour did not meet up with the side protection (which was shallow anyways), which was a cause in the loss of Prince of Wales.

The Italian battleship Roma loss was due to poor protection around the magazines, while the other Italian battleships sunk at the Battle of Taranto raid were due to a poor torpedo protection scheme; the Italian battleship's protection scheme was that the volume of the torpedo belt was filled with a large cylinder, which was in turn filled with closed tubes. Following the path of least resistance, the blast from a torpedo traveled around the cylinder and concentrated itself against the weakest point of the complex structure supporting the cylinder: the concave holding bulkhead. This bulkhead acted much like a dam mistakenly built bowing downstream, rather than upstream against the current. This concave surface was structurally the weakest possible arrangement for containing the force of an explosion, and to make matters worse, the workmanship was also defective.

The loss of the Japanese Kongō-class battleships were due to poor protection; the class was originally designed as a battlecruiser, but was modernized into battleships. As such, the armour protection was much thinner than other battleships of the war. The loss of the Fuso class battleships were also due to a very similar cause; thin armour protection (especially around the magazines). The Yamato class battleships also had a defect in the protection system; Yamato's system suffered from ineffective joins between the lower and upper armour belt, which was vulnerable to torpedoes.

The loss of the American battleships during the attack on Pearl Harbor is linked to the readiness state; the American battleships were not in fighting condition, and poor damage control on some ships contributed to the loss. After Pearl Harbor, no American battleship was ever lost during the war.

Today's weapons may be more accurate, but they are not as potent as you may think; the warhead on the Harpoon missile is only equivalent to a 500lb bomb (the same across many other anti-ship missiles), and many of today's warships are not armoured. Furthermore, large ships are often notoriously difficult to sink; for example, the SS Ohio is an example of how difficult it is to sink a large ship.

But today's weapons have much more penetration power. Today's ships are unarmored because no amount of armor could resist penetration by today's high speed missiles, while during WWII armor was thought to be able to greatly reduce the impact of air-dropped bombs.

Todays Nimitz class CVNs have an armoured flight deck and hangar deck. And armoured hull from the flight deck down to the keel(all 9cm thick). In addition the nuclear plant is armoured with armour that is ..shall I say extremely thick.

No, the reason why most ships today are not armoured is a shift of emphasis from resisting attack to intercepting the attack before it has a chance of causing damage. That means shooting down the bomber before it has a chance to even drop a bomb.

The penetration power has not increased; rather it has DECREASED. What has changed is that the target is more often than not to be unarmoured. This has made the appearance that today's weapons are more powerful; instead, they are more accurate than before. I doubt your 500lb warhead travelling near the speed of sound is able to penetrate 3.5" of armour and do significant damage.

Re: Ideal chinese carrier thread

i guys !
(sorry for my bad english, i am french:D)

see the truth from the facts and images

aircraft aircraft of modern design were have only a few occasion for subtains real damage.

disregard test on USS America in 2005 (secret test, any valuable information open to public)

2 aircraft carrier of "modern" design have had real damage
in the 1960s, the USS Forrestal and enterprise saw fire following the explosion of ammunition (bomb, zuni rocket & galon tank).
In each case, the flight deck was badly damaged, even holed and dozens or hundreds of sailors killed. Of course, none of these ships were threatening to sink, but the damage was still serious. (with possible dramatic consequence in war, because a possible repeatdly ennemy attack on damaged aircraft carrier:(.
it is certain that the impact of torpedoes or missiles can sink aircraft carriers !

just see the years of 2000-2008 test on torpedoes on decomissioned "Spruance" destroyers, 1 torpedo can cut into 2 part a ship of 6000 tons and 160m of lenght !

the images are better than long speeches

Personnaly i think,:coffee:
for a us aircraft carrier:
- to rend his inoperable: 1 or 3 torpedoes, to sink: 3-5
- to rend his inoperable: 2 to 5 missiles (this depend of kind of missiles* & aera of impact), to sink: 4 to 8/12....

* of course, missile with conventionnal warhead:D

LOL, not impressive
why ?

although the flight of uss forrestal (modern us aircraft carrier design) were still thick (probably nearly same as nimitz)...see this picture

the damage were very serious, although the flight deck were thick (see the pictures:D)
remaind you, the most powerful russian missile cruise & anti ships missile carry warhead of about 500-750 Kg (1000/1500 lb):D

a us super aircraft carrier were vulnerable, and to be sink:D

Re: How Do You Sink A Carrier?

gerboisebleue, You need to read the much eariler post in this thread and others I made about sinking a carrier. In fact I pointed out the tragic fires on the Forrestal and Enterprise. I sited them as examples of how much damage an USN super carrier can take. In case you did not know I actually served in the USN for 20 years. I did serve on CVs.

Since I did mention this previously I will mention this again. The armour surrounding the nuclear power plant is 40cm thick. Believe it or not.

a us super aircraft carrier were vulnerable, and to be sink

Sunk Really? Mission killed? Yes. Sunk? Very difficult if not impossible with conventional weapons. If your attacking force can get through the layers of protection surrounding an USN CVN.

I'm out.

On the Forrestal class carriers, the flight deck is not armoured. The hangar deck, however, is.

I think you are being extremely polite :) ; 3 modern torpedoes will definitely sink a carrier . If one were to factor in modern supercavitating torpedoes (e.g Shkval 2 ), I daresay 2 will rip the carrier into half (or even 3 pieces ). I doubt very much a 400 mm armoured waterline (even if they do exist) will make any significant difference.

The laws of physics cannot be rendered ineffective so simply . The amount of kinetic energy from such a torpedo ( a function of mass and velocity) is just too great .

Re: How Do You Sink A Carrier?

On the Forrestal class carriers, the flight deck is not armoured. The hangar deck, however, is.

Not exactly true. Forrestals had flight decks of HY-80 steel, the same material as the deepest diving submarines of the time. This was assuredly considered to be "armor". At some point in the line the US began to build flight decks of Nimitz class carriers out of HY-100 steel.
Forrestal had multiple 1000 lb warheads detonate on deck, plus a lot of smaller ordinance. That should be a testament to the basic strength of those ships, which were only two thirds the size of a Nimitz.
Back then there was no foam fire fighting system in the hanger, only a salt water spray, and no fire fighting system at all on the flight deck. The situation had not been remedied yet when Enterprise suffered her tragedy. Neither had any automatic foam system to quickly corral a major flight deck fire, so their fires quickly raged out of control.
For a comparison of how a similar mishap is controlled today, see the two mishaps Nimitz had since then. The first was a flight deck crash that caused multiple warhead cook offs on deck, but the fire was quickly controlled. Repairs required something like 48 hours in Pearl Harbor, removal of the bodies and a return to full operational status. In 1988 Nimitz had another big flight deck fire when an A-7 being serviced on deck lead to the firing of that airplane's cannon. Fire quickly engulfed seven or eight airplanes, but the fire was out almost as quickly as it started due to the flight deck foam system. The damaged aircraft were literally shoved overboard, a careful FOD walkdown conducted and flight ops recommenced in hours. No damage to the ship.
