Carriers

Yes but the nearer you are to Hostile mainland or port or whatever, the more vulnerable you become. the british were lucky that they had to fight falklands from a safe distance, out of the range of most of the argentenian arsenal. However fighting close to the argentenain mainland would have been a totally different story ( a horror story). Similarly, the gorshkov has a good chance of gettin blown up if it operates close to pakistani shores where it would have 2 face everything pakistan throws at it.
But a carrier is not designed to engage at a shore bombardment type range. Any carrier driver will stand off so that landbased "enemy" aircraft have a further distance to travel.

The further the distance, the less the loiter and hence engagement time, the greater the bingo chance happening early.

It's why cruise missiles would be used to remove and compromise all airfields close to the coast and close to the groups sailing area. You force the aircraft to have to take off from further inland so as to extend their range and reduce their engagement time.

Any carrier driver who came in close would be an idiot. The british used their carriers in the falklands properly. Under a different scenario the battle plan would have been different.

Nobody plays to their enemies advantage. Thats why the US is so dominant in conventional warfare, they slowly (sometimes) peel back the layers of defense so that remaining forces can be bludgeoned in a decisive fashion.

A CVN strike force, and cruise or ballistic launching subs working together have some considerable advantages. In the USN case, you are talking about a Navy that has the most experience of any other navy (and probably all carrier using navies together) of deploying carriers and of developing a symbiotic battle doctrine. The electronic perimeter around a USN CFS is almost 1000k's. An aircraft has to penetrate half that gap without being detected to even get a chance to launch a long range anti-ship missile. That missile then has to travel the last 500k's without interference and be able to effectively strike a target which has also got it's own electronic defence measures to "be somewhere" else.

Good luck!

As an example, the Chinese "think" they can handle 2 x CSF's and possibly stall them enough to get onto Taiwan. That conveniently ignores the way that USN carriers work, the fact that they are NETFORCEd and the fact that at the moment the USN has 7 strike groups "training" in the region. The argument that the chinese have a capacity to use their subs to compromise the USN fleet is a nonsense. In peacetime the fleet has 2 escort SSN's. There are 12 carrier groups. That means that 24 subs are committed to the fleet. 27 SSN's and 2 SSGN'x are therefore running loose and autonomously. 20 SSN's are in active reserve. If the USN was able to top and tail the best submarine force (numerically) in the world in the 80's, how hard do you think it is for them to T&T chinese subs?

I know how noisy a Kilo is - and they won't survive more than 15 minutes in a shooting war if they are being hacked by an SSN. The combat system on the Kilos is less than stellar, the Songs even less so. The Hans sound like trains driving underwater with all their orifices open. The theoreticals that people talk about in scenarios like the straits are exercises in patriotic optimism and have little bearing on how such a battle would evolve in the real world.

eg. 1 x SSGN is able to compromise every chinese east coast naval and air facility if they decide to launch against a chinese attack on US forces. In the 80's it was estimated that the USN would be able to decapitate over 90% of the russian sub fleet within 30 minutes - well before they were able to launch, and if those russian subs started to go through a launch sequence, they would have sunk them immediately. The US has always made it clear that a response on a carrier is akin to striking a mainland city and that they would respond disproportionately.

If you want to wage war on a carrier - then try a smaller less capable navy. ;)

What would happen if a Modern Nuclear Powered aircraft carrier has been sunk, surly there must be a mechanism in place to ensure nuclear material doesnt leak into the ocean?? :?

I think the most cost effective way to sunk an aircraft carrier is by an efficient hunter killer submarine.

regarding what sirri said, it is a normal tactic of communist nations to put up 2 or 3 of their hunter killer subs against a merchant convoy. however to due lack of C3I and communicaton ( cooperation another story) they were unable to achieve decisive results. If however the same tactics are used against an AC group with deficiencies taken care of someone might make a difference.

of course. but the problem is the defences around an aircraft carrier. it is very very difficult for any missile to penetrate the carrier shield

well unless you try lobbing a 100 SSMs at the carrier group like the soviets, india doesnt posses the ability to stop that. but neither does Pakistan have the capability to initiate that.

GF, there is also another factor, it depends on where the missile hits the carrier.
It does, but not on a larger CV like the CdG or a CVN.

Carriers (especially larger ones) have citadels in place. Smaller carriers don't.

eg, it's generally accepted that a Mk48 ADCAP can kill a guided missile destroyer or light cruiser to about 9000t if it hits it anywhere. OTOH it's also accepted that it would take approx 4 Mk48 type weapons to do significant damage - let alone kill a large carrier. Torps work on spine breaking, so they concatenate their destructive power by using physics to assist in the kill.

An ASM doesn't have that advantage at all, it's a straight kinetic, then explosive reaction. There is not enough explosive power in a Yakhont/Brahmos to kill a large CVN.

They've done real time tests on large distressed merchant vessels which were obviously not citadeled and bunkerage configured like a large CV or CVN

2 x Brahmos would most likely kill a small carrier if they were able to be placed in the same spot (which would need an excellent terminal guidance capability), however, they aren't a large vessel ship killer by any means.

Maybe a golden bb shot like against the Hood, but that would be extremely lucky.

I suppose your referring to the two Brahmos hitting something like the Viraat right? or one of those smaller carriers spain and argentina posses.

Torps are basically the best weapons poor nations have against a carrier unless they can afford advanced technologies like submarines that can fire missiles from underwater ( the missiles and the technology an altogether different affair). Recently the chinese have acquired this capability as well as ability to sink US ships (not carriers mind you) with single one shot hits. This info is available at news week and sino defense.

If I was a carrier driver, I'd be more worried about a quartet of wake sniffers hitting me up the clacker than a couple of supersonics coming in. If it was a US CSF with Aegis or a UK CSF with PAAMs then a supersonic strike would not cause me to lose as much sleep as a team of SSK's shunting off some wake sniffers. Especially the UK Torps which have a 60km range.

There are some nasty torps currently under development that would make quite a few skimmer drivers nervous.

I'll be at the UDT Submarine Warfare Conference in Hawaii in Oct, so if there is any unclassified detail I'll post some info.

The latest versions of the Ageis types can't reload their SAM's at sea so when they are out of SM2's looses a large part of it's defence. in essence one could launch a HUGE number of chep Anti-Ship missiles with the goal of wearing down the taskforce's defences. After that you launch your sunburns and sink the entire taskforce.

Are you serious? In a peacetime disposition and in a known volatile area the fleet normally comprises 1 x Tico, 3 x Arleigh Burke and 2 Guided Missile platforms. That means well in excess of 500 missiles in bunker.

Name 1 country that is capable of surging 250-500 strike platforms and able to penetrate a battle dispersed screen to a depth of 500km before being able to get to the centre of gravity of that fleet. Ans = 1 (if they're lucky). Even they (the Russians) have a fleet that is estimated to only have 20% of it's active penanted fleet seaworthy, and has an airforce that is progressively being sold off to India as they need the money. They won't sell off supersonic strike bombers and anti-shipping specific aircraft to China as they mistrust them. Out of all the platforms they have that are capable to go the distance and attempt to break the screen - well, they have less than 20 of them in total. They were even at the stage where last year they were prepared to lease Tu-142's to the USN so that they could practice swarmed strikes. They've been selling their missiles to the US (KH-31's and rumour has it some Sunburns) to act as Supersonic targets. China is not even a 10th of the capability of the Russian current ORBAT in capability. India arguably is better at AS roles than China in current capability and platform potential.

The US has spent 20 years training against supersonics (why some people think that a supersonic cruise is a new invention is beyond me :eek ). The only navy and airforce that had the capacity to surge and swarm were the Soviets in the halcyon days of their navy and airforce - and even their post cold war documents indicated that they believed that less than 5% of their platforms would break the screen - let alone get the capital targets.

There is no country outside of the US that can surge sufficient platforms to overwhelm a strike force - the mere gearing up to do it would be picked up by satellites and sigint days before a launch.

The policy now is to surge CSF's in theatre battlegroups - hence the recent exercise to surge 7 groups into the China Sea. The next ecercise will have 6 CSF's surged together.

The other issue is that the US sees that an attack on a CSF is tantamount to attacking the CONUS - any nation that strikes or attempts to strike a CSF will trigger SSGN's launching cruise missiles (at best) against their shore based important assets - and the bet is that the US would strike a symbolic asset to make a significant point.

There needs to be some reality attached to this. Doctrine and response is not dealt with in isolation.

We're not talking a deep sea battle here the Carrier taskfore is usually employed to strike against ground targets that means it's less then 500km from the coast to start with, the persian gulf is at most 400km wide and the US got carriers there. Besides all missiles don't have to come at once thats whats so (strange) you can use a small group of 50 aircrafts carrying 2-4 AShM's thats 100-200 missiles launched from 200km+ range that skims all the way to the target they don't have to be supersonic because they would have to fly much higher then.
If you do that mission at most 5 times then the US carrier group is gone if it hasn't reatreated before then putting it in a much poorer position to launch strikes.

I'm sure that the day a US carrier group is attacked it will be an attritional battle like the frontal charges of ww1 and if you can't reload your machine guns you're in pretty dire straits.
The Swedish Airforce could probably have a go at it 200 Gripen aircraft carrying 2 RBS15 mk3 AShM's each and advanced jaming equipment on the other pylons besides AAM's, even the powerfull radars of Hawkeyes and AEGIS can't burn through that at 500km.
You might have confused my statement with nations that the US could have to go to war with Today then no nobody except China could probably do this. But if the US is ever forced to fight a truly developed country again with a first class defence force this might be a real possibility.

On the other hand someone might just invent and Anti-Gravity AShM that has a stealth hul and is virtually undetectable that just sneaks into the carrier at 30mph.

Fair enough, but close in contact dictates that in a volatile area (rather than a benign environment) that any potential threat will be removed by TLAM-SLTLAM etc... Hence LA's and SSGN's. A carrier commander who went in close without the proper implementation of combined arms and combined strikes would not hold his job very long. CSF's don't work in isolation - they're autonomous - but not isolated. Thats the subtle disconnect that a lot of people miss.

Anything that hits the 800km perimeter is automatically scaled at a threat level. Don't you think that a CSF commander under NETFORCE is going to be able to determine the likely OPFOR assets in theatre, deployed the fleet as a layered response and also bought in peripheral (non CSF) strike elements? At 200k a flight of incoming would be at risk. TU-142's would have been engaged at 450k's by organic air defence, at 200k they are starting to come into LR-SLI response areas. At the same time that the OPFOR packages are coming in, the fleet or LR strike are going to strike the home airbases with TLAMs SLTLAMs - hence the aircraft have no base and have just had their bingo call escalated considerably as they need to find another base to return to.

Yes, but you've made the mistake that most wargamers make - the US has a combined package response. They act concurrently in strike and defence. They will take out the airbases within a 600k radius with cruise or B2's and they will alter the available base points to effect the OPFOR bingo issues.

Darkwand said:

Hence why the new focus is on theatre strike forces and extensive use of SSGN's and B2's

NETFORCE virtually gives a 900km perimeter. 500km doesn't need to be burnt through. Depending on theatre event, they are also watching the launch points with sats. Eg China is virtually on 24/7/365 sat coverage. The US is also at a point where film arrays are becoming a reality. That means that it's possible to have every plane so equipped acting as a phased array panel in its own right. That is enormous coverage if it is finessed to a deliverable capability. In addition, you now have Growlers coming into service. The USN just doesn't have one arrow in its quiver - it has different arrows with different warheads and multiple quivers. Subodai taught every commander that lesson 700 years ago.

Even China admits that the most they can cope with (and thats not the same as sink) is a 2 carrier strike force. That also assumes that the CSF commanders are morons and are playing to the enemies advantages and not their own.

I think the immediate future lies with hypersonics. There are already technologies being developed to identify stealth enhanced torpedoes. One of the techs I deal with is signature management - the stealth torpedo has been on the agenda for quite a while.

I wasn't trying to win, I just wanted to show probable outcomes.

Yep, I do like Swedish kit. ;)
