We talk about individual
weapons and sensors but almost always in isolation. The more important question is how will the
overall ships perform? The Navy is
experimenting with independent surface action groups. How will they perform in combat? What will happen when they meet an enemy
surface action group? Let’s have a
little fun and speculate about future naval combat. Specifically, what is a future naval surface
battle going to look like?
Well, at one end of the predictive
spectrum, it may be a combined arms action with airborne, satellite, and
subsurface surveillance contributing to the situational awareness and various
air, land, and sea networked forces unleashing an exquisitely timed concentration
of firepower on the opposing force – at least, that’s the Navy’s rosy
view.
At the other end of the
spectrum, the opposing naval forces will be operating under a no man’s sky with
only sporadic, if any, surveillance available and few, if any, other forces
available for added firepower when the two “blind” forces stumble across each
other, since all other forces will be tied up with their own, immediate
concerns while the opposing air forces hammer back and forth at each other,
largely uncaring about the naval situation beneath them, until they can establish
aerial supremacy – at least, that’s ComNavOps’ and history’s realistic view.
So what happens when these
two forces meet? What will the resulting
battle look like?
Let’s start by stipulating
that the surface forces will consist of a few to several destroyer type ships,
typical of modern navies.
Each side will have the same
type of short range UAVs that may offer some “early” detection. We’ll assume that both sides simultaneously
detect each other at around 30-50 miles distance.
An anti-ship missile
exchange will ensue. Of course, the US
Navy has no anti-ship missile, currently, but we’ll assume that this
hypothetical battle occurs far enough in the future that the USN has the Long
Range Anti-Ship Missile (LRASM) or an equivalent. Neither side will have enough anti-ship
missiles (ASM) to overwhelm the other’s defenses.
The ships will have a relative handful of ASM’s each, unsupported by any
electronic support or penetration aids.
The ASM’s will be going up against the other side’s Aegis-type defenses. Odds will favor the defenses. One or two ships may be damaged. Perhaps one ship from each side will be
mission killed or sunk. This will leave
both sides with their anti-ship missile inventories exhausted and their AAW
inventories severely depleted. Will the
remaining ships choose to use their remaining, precious AAW missiles in the
much-hyped anti-ship mode even though they can’t do much damage or will they
elect to save them for the AAW role they were intended for since the commanders
will have no idea whether the enemy has any anti-ship missiles left? The prudent commander will save his AAW
missiles. Thus, we now have two surface
forces, largely intact, headed towards each other and out of anti-ship
missiles.
Why do I assume
that the anti-ship missile exchange will be inconclusive and largely
ineffective? After all, aren’t many
people scared to death of large, heavy, supersonic missiles? Well, the answer is that the historic
database on anti-ship missile effectiveness is pretty bleak (1). Anti-ship missiles
have just not proven to be effective in combat and until there is evidence to
the contrary, I’ll stick with actual data.
Interestingly, there are as many proponents of impenetrable AAW defenses
as there are unstoppable anti-ship missiles.
One of the two sides is wrong and history says it’s the unstoppable
anti-ship missile that is overrated.
What happens next?
Assuming neither side veers
off, a naval gun battle is what happens next.
Now, here’s what it could
look like.
Both sides have roughly
similar naval guns, meaning 5”. Burke
class ships have a single 5” gun each.
Ticonderogas have two 5” guns.
The Type 051C, 052B, and 052C destroyers carry a single 4” (100 mm)
gun. The newer Chinese Type 052D
destroyer and the upcoming Type 055 destroyer carry a single 5” (130 mm)
gun. Interestingly, the older Sovremenny
type destroyers carry 4x 5” (130 mm) guns and would offer a significant
advantage.
Firing would begin around 12
miles or so with a significant probability of hits occurring around 5 miles.
Structural damage would be
light. The 5” gun is not a ship
sinker. However, exposed sensors and
weapons would be quickly damaged and destroyed.
Modern 5” guns are mounted in weatherproof, unarmored housings and,
hence, are quite susceptible to shrapnel damage. Guns would be quickly put out of action. Sensors would be quickly damaged and degraded
which would significantly decrease the accuracy and rate of fire of the
surviving guns. The ships would have to
continue closing to make up for the loss of accuracy and the gun battle would
devolve into an extremely close affair.
Neither side would be able to sink the other’s ships and the result
would be individual ships breaking off and withdrawing as casualties mounted
and effectiveness diminished. The net
result would be a gradual, mutual separation and withdrawal.
What could tip the balance
is a couple of lucky, early hits that incapacitate the other side’s guns either
via damage/destruction of the guns or damage to the sensors of the fire control
systems.
The other aspect to this gun
battle that bears discussion is torpedoes.
All destroyers carry torpedoes.
Both side’s ships typically carry 6 lightweight torpedoes (two triple tube
launchers) intended for anti-submarine use but they presumably have an
anti-surface mode. The US Navy’s
torpedoes have a range of around 6 miles.
Presumably, the Chinese and Russian versions are similar. Thus, as the ships close in their gun battle,
a second, parallel torpedo exchange could take place. Given the lightness of construction of modern
warships (US warships, at any rate – I don’t know about Chinese and Russian
ships), torpedo hits, even from lightweight ASW torpedoes, could prove to be the
ship sinker weapons that the 5” guns are not. Again, victory could go to the side that
achieves the greatest success in the torpedo phase of the battle.
Another aspect that could
significantly impact the outcome is the presence of external support. While we ruled that out for the purposes of
our scenario, it is fair to note that the US will likely be fighting far from any air or naval
bases and external support will be unlikely.
In contrast, any likely enemy will be fighting in their home waters and
will have an abundance of external support in the region, if not readily
available. Thus, the odds that the enemy
will actually benefit from external support is much greater than the odds that
the US will. That’s
a significant factor to consider as the US heads down the LCS-reliant surface action group
path.
Admittedly, one can
reasonably debate my vision of a future naval battle but recognize that it is
based on logic and what little actual data there is so if you want to argue,
you have to account for the actual data regarding ASM performance and ship
construction practices (lack of armor and structural strength, for
example). Finally, remember that this is
a for-fun mental exercise. Don’t get too
twisted up about it!
