Why Aircraft Carriers Still Rule the Oceans

An anonymous reader writes "Despite being created during World War I, the modern carrier has evolved to be the pinnacle of modern warfare's best and most visible symbols of power. Nothing says 'show the flag' more than a carrier off an enemy's coast. Some, though, have called the carrier a 21st-century version of a battleship — high on looks and weapons but vulnerable to modern weapons. Critics note air-power killed the battleship; people now suggest super-sonic 'carrier-killer' missiles will make the carrier a relic of the past. With their cost in the billions of dollars, some point to killing off carriers as an obvious cost saving measure. Carriers though still have a lot of uses. Many navies, like India and China, are adding them to their arsenal, and they are still feared by many. While carriers might be old, they are a symbol of power that no missile or submarine below the surface can match yet."

      Of course a better projection of power instead of obsolete battleships or airplane carriers would be the Arsenal Ship I worked on in the 90s. It was filled with nothing but self-guided missiles & required very minimal staffing. Just enough to watch the radar and load targeting solutions. Nothing says "power" like a ship that can launch 500 nuclear-tipped tomahawks in less than ten minutes. Or a barrage of ship-to-air missiles to shoot aircraft carrier attacks from the sky.

      And the other way around. Countries that have a carrier, big. A carrier is a toy for the big guy's because it needs a whole squadron around it to protect the carrier and for all your other naval activities a different fleet has to be operational.
      It is a ship that is a big target in the best of times and a big, cumbersome, slow moving, blind (there is a visual and radar blindspot with a mile radius around it) and hopelessly lacking manoeuvrability all the other times. In order to have one floating around, one needs at least a handful of frigates (all of them equipped with a helicopter) , a minesweeper or two, one auxiliary ship and preferably a submarine or two and a hospital ship.

      And once you run out of non nuclear missiles how are you going to bomb ground targets?

      Carriers don't rule the oceans. Submarines and missile cruisers rule the oceans. Carriers rule the land near oceans, they are portable airpower, which makes them more cost effective than missile boats for air support and air superiority roles.

      Big ships are just platforms. If you put large very heavy guns in them they become of significantly lower versatility - you need to completely rebuild the ship to have something without the guns. Aircraft carriers are as versatile as the aircraft you put on them. Need helicopters to support a naval invasion? Use a carrier. Need airborne surveilance and control? use a carrier. Need some combination of air superiority and ground attack? Use a carrier. In this sense a carrier is just a specific variant of big ship, that happens to be more versatile than the previous two iterations ('pre-dreadnought' battleships that were a mish mash of guns, post dreadnought 'big gun' battleships).

      Granted, it depends very much on the type of war you have to fight. But that's the problem. Your 500 nuclear tipped tomahawks is a job for war no one is fighting at the moment. You're not going to nuke Damascus or Tehran to get Assad or the Ayatollahs out of power (in fact using nuclear weapons in this case would be almost diametrically opposed to that goal).

      Also, it's not like navies are composed entirely of aircraft carriers. The US has about 50 in total, of nearly 300, and carriers (especially the big ones) are hard to make in a hurry, so you tend to be top heavy and have a disproportionately large inventory of large assets - if it turns out you need 50 destroyers by the end of next year 50 shipyards could probably pull that off, if you need 5 aircraft carriers by the end of next year it isn't going to happen. The Royal navy has 80 ish ships, of which two are supposed to be full blown aircraft carriers, a heli carrier and then some 'landing ships' which are like half heli carriers. With that diverse collection of assets some can be carriers, some can be 'arsenal' ships, some can be all sorts of different things, until you know what war you're fighting it's a matter of being reasonably prepared for whatever.

      Carrier operations off pakistan for example, related to Afghanistan, are because Diego Gracia (which doesn't actually belong to the yanks) is the nearest US allied base, and it's in the middle of nowhere. Ok for staging disaster relief and nuclear weapons, not so good for ground support in north western afghanistan. And as we just saw the hard way, aircraft based on the ground in theatre can get blown up.

      One of the lessons sept 11 should have taught americans is that their notions of 'power' are outdated and whimsically useless, you could have nuked Kabul or Riyadh into the ground in retaliation but what would that have gotten you? Capabilities matter, but being capable of doing something useless doesn't translate into power, and sure, a boat with 500 missiles can hit 500 targets - if you're lucky - but those missiles take a long time to go from off shore to wherever you need them, even if they land in the right place the thing you want destroyed might not be there, or might be too well fortified against the size of missile you can launch. They aren't useless by any means, but they aren't a panacea, nor are carrier based assets.

      Anyone who you could seriously want to nuke can nuke back (russia, china, north korea, pakistan), and if they can't nuke you they can at least kill millions of your allies. MAD sort of implies *mutually* after all. And anyone else you don't really want to nuke because you're more likely to get something out of conventional overthrow of the government.

      You forget, 90% of the fleet's firepower comes from carriers (in the USN at least).

      As far back as the 60s the US thought that perhaps carriers were obsolete and too expensive and should be gotten rid of. However, the various wars and skirmishes (eg El Dorado Canyon/Libya) have shown the US time and again that the carrier strike group is still unparalleled in mission range, variety, striking power and capability. Hence, the US has 12/13 (depending on the rate of building) and lots of other countries want them too. The UK also though of getting rid of its carriers but fortunately they were around when the Argentinians occupied the Falkland Islands. Without a carrier the UK would have had zero chance of restoring sovereignty to the Falkland Islanders (who govern themselves but cannot defend themselves).

      However, on Slashdot the uninformed start with purile "penis" comparisons as if US defense policy was based on this (prestige follies happen in banana republics like Chavez's Venezuala or Qadaffi's Libya - but not in the US; the US follies are based on the economic benefits of the military-industrial complex in each State, but not braggadoccio as the posters suggest).

      Aircraft carriers are an important part of global power projection. Without a carrier you simply cannot enforce your will around the World (unopposed aircraft can defeat all ships and submarines; if you don't have a carrier to counter this then your Navy is useless - which is why the Russian and Chinese Navies have carriers mostly tasked with protecting their fleets).

      nb: with regard to carrier killing missiles. The US purchased advanced hypersonic Russian missiles and tested/developed defenses against them. Work is ongoing on improved versions of the Standard Missile against ballistic missiles like the DongFeng 'carrier killers' and lasers are being tested against Brahmos and other hypersonic sea skimming missiles. As a result the greatest threat to carriers is not missiles, it is submarines (especially those with Air-Independent-Propulsion, that are very difficult to detect). A torpedo from a submarine also contains a far greater payload than missiles (this includes nuclear tipped torpedoes, Soviet attack subs were issued with two nuke as carriers are so valuable [because they are so powerful] that bagging one was worth the risk of escalation).

      So, the manhood insults about navies may be cheap lurlz but show considerable ignorance about modern military affairs and why there is so much activity around developing both naval aviation and counter-carrier capabilities.

    Now, having corrected the spectacular misconception, here's something to chew on. Presidents can't spend a single dime without the House of Representatives budgeting it. The House has COMPLETE control over the purse strings. All the Presidents do is PROPOSE budgets to the House. Then after the House passes a budget the Senate and President have to concur with it; there is a dance of reconciliation between the House and Senate, and then the President just says "yeah fine, I guess" or "Hell no", after which Congress can still override the veto.
