whats the biggest gun av8 can have?

Projected largest caliber weapon is 30mm only, although can also fit a 120mm mortar or anti-tank missiles.
Can see full projected variants of AV8 in pic below

I wonder what the PLA will become in the next 20 years in the meantime if China's economy continues to prosper like today.

Modern guided torpedoes won't do that much damage anyway, because the explosive charge is usually much reduced to make way for things like seeker heads and steering controls into the body of a torpedo. So I doubt a torpedo can sink a well-prepared ship nowadays. Cripple, yes,but probably don't have the power to sink a warship by itself. Although some modern torpedoes use shaped charge to maximize damage, its not like the olden days where torpedoes were unguided, but can pack as much as 1 ton of TNT into each torpedo.

Now that's firepower.

Yes, nice, but the 'ship breaking in half when hit by torpedo' effect is actually happens only occasionally, with some very specific conditions.
Actually what happens is that the torpedo is actually detonated under or at the keel of the ship, creating a supercavitation shockwave bubble. This can actually result in 2 effects, either the hull collapses into the hollow space in the water created by the bubble or is actually pushed up with the bubble's shockwave.

Either case, the hull, temporarily unsupported by water along its length and impacted by the high volume and speed of water rushing into the bubble, can break apart quite dramatically,but ONLY if the ship is hit in a specific manner. A simple side impact directly to the hull won't recreate this effect. Of course people associate this 'breaking apart' effect with all torpedo impacts, because its so dramatic but in fact it happens only occasionally if not rarely.


What really happens

Reference: Effect of underwater explosions

Sure it can, but I think real-life scenarios most will try to hit ship directly rather than try to achieve this effect. I think a shot direct to the propeller or steering gear is more preferable and can usually guarantee a mobility kill on the ship.

I am still thinking with proximity fuze, only that the torpedo should be aimed for the propeller or steering gear. Most torpedoes can do both active and passive homing, but for a torpedo to use active sonar for locking onto the hull of a target is too noisy and can potentially give the target unnecessary warning. A passive mode to lock on, with the torpedo slowly following the general direction of the target ship from behind, following the sound of the propellers before going full speed from close range can give a much nastier surprise to the target. This can be helped by the fact that the wake of the ship is rarely monitored by ship's sonar due to the interference noise of the propellers themselves.

Also the fact that the propeller and rudder is relatively fragile and can be destroyed quite easily as they are quite exposed.

These video should answer some of your questions

Yup...... no ships can escape from heavyweight torpedo....it is designed to weaken the structure & break it to 2 parts.

hopefully Indonesia will buy Typhoon soon。

Lepas Landas ?

The turret still looks ridiculously tiny given the small size of the tank.
I don't see the turret actually giving much protection against a hit. I also doubt the combat staying power due to the fact while the tank can hold 32 shells, the auto-loader can hold only 12 shells at a time. If the magazine runs out, the crew had to reload it manually (from outside the tank,no less!!).

quadpack is only for sylver vls, the bung tomo (and our lekius too btw) use the british GWS-26 vls designed only for 1 sea wolf per hole , so i dont see how sea ceptors can be quadpacked

photo of a sea wolf getting launched from the brit gws-26 vls


looks tight enuff 

our gowinds could possibly get the sylver though  , but hopefully we get mk41 for essm
