As usual though, Proceedings delivers high quality stuff, at least in the online edition. I'm still waiting for my hard copy, but it can wait while we take on the topic of CVN-78.
Mike Burleson took on the topic of Big carriers yesterday when he linked to this post on IntelliBriefs. The IntelliBriefs article is a decent summery, there are some factual errors but in general it sums up the global activity in building new naval aviation ships. Mike on the other hand went a step farther, when he listed 5 reasons why the dominance of the aircraft carrier is "running out of steam."
- The Nuclear Shkval torpedo
- Wake Homing torpedoes
- Air Independent Submarines
- Less vulnerable platforms duplicate the carrier's mission
- The cost
In the September 2007 issue of Proceedings, Rebecca Grant, Admiral John Nathman, USN (Ret.), and Loren Thompson attempt to defend the Navy position on big deck carriers. Up until the point I read Mike's post, I was wondering why they felt compelled, but apparently there is still a group of people who believe in the Cebrowski naval aviation model. In the article "Get the Carriers!" the authors lay out their defense. A sample:
Just what should carriers provide?
According to the critics, not much. There’s a misconceived belief among them that the need for air power is on the wane. One basic line of argument is that surface ships with missiles can replace carriers in littoral attack. Branching out, critics contend that since the revolution in strike warfare increased precision strike capacity by an order of magnitude, then micro-air wings on small carriers can do the job. It’s all framed in lurking suspicions about the vulnerability of carriers and a vague desire not to put all the eggs in one basket.
The trends in air warfare paint a different picture. Demand for air power is up, and the range of tasks is growing. Consider the recent slate of tasks for Navy carrier aircraft in Afghanistan and Iraq. They’ve done everything from providing early air support in Afghanistan in 2001 to flying more than 5,500 sorties in a little over six weeks as major combat operations began in Iraq in 2003. In the years that followed, they’ve learned to hunt insurgents, watch over convoy routes, and supply non-traditional intelligence, surveillance, and reconnaissance (ISR) from on-board systems. NATO patrols in Afghanistan do not move without air power available.
Naval aviation leadership made much of the revolution in strike warfare carried out in the late 1990s. While that was a landmark achievement, joint demand for air power didn’t stop with precision.
Revisiting Mikes position, he basically lays out 4 reasons why big decks are on the way out; nuclear weapons, submarines, VLS destroyers, and cost. Lets take them one at a time, and let me add some points the authors in Proceedings glanced over.
First, the use of nuclear weapons is just as effective against any alternative to the CVN as it is to the CVN, and perhaps more so. To casually nuke a Nimitz class CSG with a torpedo would be to kill 6500+ sailors, likely resulting in unrestricted warfare on whomever used such nukes, and probably prompting a nuclear response. Until someone can point out an alternative that can survive a direct hit from a nuclear torpedo, I'm not ready to change my mind because of this threat.
Second, I think most people would agree modern submarines are one of if not the biggest threat to aircraft carriers, but not because they are aircraft carriers, but because an aircraft carrier is a surface ship. A destroyer or cruiser wouldn't have any advantage over an aircraft carrier against a submarine, and in fact, given the mission profiles and where they are asked to operate today, destroyers and cruisers are more vulnerable.
AIP and wake homing torpedo's are clearly threats, but this argument is better used against a certain 14,500 ton littoral destroyer than it is a blue water 30 knot cruising aircraft carrier. AIP is certainly an interesting technology, but while its advantages are often stressed, the weakness (specifically the speed/endurance ratio) is too often ignored. While specific exercises have revealed success for AIP submarines, freelance exercises where a submarine threat is known to exist haven't been as successful for AIP, in fact it has been proven many times the Collins class is better suited to hunt a CVN in blue water than a U-212 is, precisely because the Collins isn't AIP.

Fourth, cost. There is no question that aircraft carriers and carrier air wings are expensive, but the question is, relative to what? The Air Force? There is a political cost there that can be very high, see Saudi Arabia in 1991 and Osama Bin Laden's reasons for 9/11. Here is my million dollar cost question on forward deployed air power launching from sovereign US property at sea that I never see answer for..., what is the cost of mission unavailable when needed? That question doesn't get answered, because Americans take for granted the awesome capabilities of our Navy, although they do pay for it. When it is said and done, the CVN-68 has 11% inflation, every other shipbuilding program in the Navy would kill for only 11% inflation. For the cost of the 7 planned DDG-1000s, the Navy can buy 3 CVN-78s. Are 7 DDG-1000s really as capable as 3 CVN-78s?
The authors though barely mentioned the main reasons I would have emphasized.
The problem with small deck carriers or cruise missile alternatives is they won't deploy the E-2Ds or EA-18Gs. These aren't just trivial aircraft randomly exclusive to big deck carriers, these are game changers and represent the quantum leap difference in capability comparisons between every other nations Navy (and in most cases, air force) and the US Navy. For all the hype regarding stealth and speed, I can't imagine a SWO is going to be comfortable operating anywhere near major air and missile threat zones without Growler and Hawkeye support. Helicopters are not a substitute for Hawkeyes, and looking forward the ideas behind EW on the UCAS-N and JSF only exists on paper.
The demand by the Army and USAF for EA-6B support in OIF pretty much sums up why calls for small deck carriers can be safely ignored, at least until there is a viable EW replacement prototype capable of operating off a small deck aviation ship.
Finally, sortie rates. My problem with the Cebrowski inspired small deck carrier cries is that the suggestions are made despite evidence that big decks support higher sortie rates at lower cost, and you can prove it. Either using pen and paper, or modeling via software like Harpoon 3 ANW, build an alternative and verify. The MoD and Royal Navy did when designing requirements for the CVF, the reason they went larger by nearly 3x the existing carriers was to support 24/7 sortie rate generation that can sustain both defense and offense in operations. In reading the requirements, the 36 number for JSFs is directly tied to sustaining required sortie rates.
A common retort is that 3-4 small deck carriers could match a CVF. Maybe, but to support 24/7 operations you increase costs substantially, because now you are supporting 3-4 different aviation maintenance crews of 3-4 different ships, and each ship has to have enough to support 24/7 shifts. Ultimately, you end up requiring more sailors, thus incurring more cost for equal capabilities, and that is in relation to the CVF, never mind the CVN-78s which are more efficient.
Bottom line, the Navy was very thorough in study of the big deck vs small deck question, and bigger won most categories.
