Carriers are mammoth
vessels. Why?
Why?
This isn’t a trick question
but it’s one that we never think about.
The answer is that the carrier’s size is determined by its air
wing.
The air wing needs an
immense flat area simply to park its aircraft on. That area must also be able to launch and
recover aircraft while not interfering with the storage (parking) of the
aircraft. That adds immensely to the
area. More flight deck room is needed to
move aircraft in preparation for launch or maintenance.
For example, the entire bow
area of the carrier is there because that much room is needed for the
catapults. If the aircraft were all
vertical takeoff, you wouldn’t need the bow of the carrier and you could lop
off the entire area from the bow cats forward.
Relax, vertical take off is not where we’re going with this. I’m just illustrating that the size of the
carrier is determined by the requirements of the air wing. The same reasoning applies to the huge
recovery area that constitutes much of the aft half of the flight deck.
The air wing also needs to
maintain itself. Thus, we have a huge
hangar for maintenance, many repair shops, lots of spare parts storage, etc.
The air wing needs munitions
and lots of them. So, a large chunk of
internal carrier volume is devoted to magazines and munition handling areas and
elevators.
The air wing needs fuel and
lots of it. The carrier, despite being
nuclear powered, needs immense fuel tanks for the air wing’s aircraft.
The air wing also needs the
mundane things like berthing, heads, showers, food and water storage, galley
space, mess decks, laundry, waste treatment, etc.
Take away the air wing and
all its requirements and what do you have?
A small, nuclear powered tugboat.
Okay, so now we’ve thought
about why a carrier is the size it is.
So what?
Well, let’s keep going and
think a bit deeper. Having asked why a
carrier is the size it is, let’s now ask why the air wing is the size it is.
Again, this is not a trick
question but it is one that is examined even less than the carrier size.
The air wing is the size it
is because of the tasks it is asked to perform.
What are those tasks? Here’s a
list of a tasks and a typical air wing’s assigned aircraft to accomplish those
tasks
- Strike and Fighter – 38x F-18 Hornets
- Aerial Tanking - 6x F-18 Hornets
- AEW – 4x E-2 Hawkeyes
- ECM – 5x EA-18G Growlers
- ASW/ASuW/Logistics – 12x MH-60(x) Seahawks
That gives us an air wing of
65 aircraft – our modern air wing.
Okay, so now we’ve thought
about why an air wing is the size it is.
So what?
Well, do you recall the
recent post on distributed costs and the resulting change in force
structure? We said that we need to
reverse the trend towards ever larger, ever more expensive, ever fewer ships
and go (return) to smaller, simpler, less individually capable, cheaper, more
numerous ships. Do you recall an
overarching theme of ComNavOps calling for more numerous and cheaper, smaller,
single function ships like dedicated ASW vessels and dedicated MCM vessels and
narrowly defined AAW escort ships and so on?
Well, the same applies to, and is interlinked with, carriers or, more
precisely, carrier air wings.
If we had a more numerous
force structure of smaller, single function ships what impact might that have
on carrier air wings?
Instead of the Navy’s
current carrier escort of three or four Burkes, each with a single helo,
providing ASW, imagine if we had 16 smaller, dedicated ASW vessels, each with a
single helo for a total of 16 ASW helos.
We wouldn’t need the carrier’s helos.
The requisite number would be distributed throughout the escort. So, the air wing’s helos could be reduced
from 12 to 2 (for plane guard duty).
Suppose we were to
distribute the air wing’s capabilities across two carriers instead of one. That would mean each air wing would have 2
Hawkeyes instead of 4 and 2-3 Growlers instead of 5.
We don’t want to distribute
the air wing’s strike/fighter capabilities, however. Quite the opposite. We’d like to increase the number of
strike/fighter aircraft. So, what if
each of our notional two carriers had an air wing of 38 Hornets, 6
Hornet-tankers, 2 Hawkeyes, and 2 Growlers?
That would give us an air wing of 48 total aircraft with the exact same
combat capability as a current air wing!
Because the air wing is only
48 aircraft, a 26% reduction in numerical size, the carrier needed to operate
the air wing could be substantially smaller.
Let’s go still further. If we’re willing to accept a slight reduction
in launch capacity, our notional carrier could be equipped with only 2
catapults instead of 4. All four
catapults are rarely (almost never) operated simultaneously. They’re mainly useful for full strike
launches which is less and less a viable operation. A reduction of two catapults gives us a
significant reduction in equipment and required flight deck space. Remember earlier in the post when we noted
that if it were not for the two bow catapults we could lop off the entire bow
section of the carrier? And with a wing
of only 48 aircraft the bow flight deck area wouldn’t even be needed for
parking.
You can see where this is
going. A smaller air wing means less
flight deck area, less hangar space, fewer repair shops, less personnel
berthing, etc. In short, it means we can
have a much smaller carrier. In this
concept, we would actually have two carriers instead of one and they would pool
their Hawkeyes and Growlers to have the capability of a full air wing today
plus twice the strike/fighter numbers.
This would result in a force of 20 carriers as opposed to today’s 10,
resulting in distributed cost, distributed and increased lethality, twice the
combat aircraft, and, most importantly, distributed risk so that we would
actually be willing to commit carriers to combat.
So, why is the carrier the
size it is? The answer is, for no good
reason.
