As we know, the WWII German surface navy never accomplished
anything significant and most of it was expended in piecemeal fashion with
little to show for the effort. Many
historical observers believe that there was little else the German navy could
have done beyond what they did but is that true? Let’s take look at how the German navy could
have been employed and what lessons their actual and possible employment holds
for us, today.
To ever so briefly review, following is the state of the
German and British navies early in the war (around 1940-42 or so) or, at least,
what they could have been without losses.
11 Aircraft carriers
3 Glorious class commissioned
around 1916
1 Argus class commissioned 1918
1 Eagle class commissioned 1924
1 Hermes class commissioned 1924
1 Ark Royal commissioned 1938
4 Illustrious class commissioned
1940-1941
22 Battleships & battlecruisers, of which only two were
post-World War 1.
5 Queen Elizabeth dreadnoughts
commissioned around 1915
5 Revenge class dreadnoughts
commissioned around 1916
2 Nelson class battleships
commissioned 1927
5 King George V battleships
commissioned around 1940-1942
2 Renown class battlecruisers
commissioned 1916
2 Courageous class battlecruisers
commissioned around 1916
1 Hood class battlecruiser
commissioned 1920
66 Cruisers, mainly post-World War 1 with some older ships converted for AA
duties.
184 Destroyers of all types and eras.
Note that the British carriers were barely worthy of the
name, employing WWI era bi-plane Fairey Swordfish torpedo planes, Blackburn
Skuas, and, later, Fairey Fulmars. The
carrier air wings were generally quite small by US standards. That said, they accomplished some amazing
feats.
In comparison, in the same 1940-42 or so time frame, the
German naval order of battle could have consisted of the following.
4 Battleships
Bismarck
Tirpitz
Scharnhorst
Gneisenau
3 Battlecruisers
Scheer
Graf Spee
Deutschland (renamed Lützow)
2 Dreadnought Era Battleships
Schlesien (dreadnought)
Schleswig-Holstein (dreadnought)
3 Heavy Cruisers
Admiral Hipper
Blucher
Prinz Eugen
6 Light cruisers
11 Auxilliary cruisers
30 Destroyers
Comparing the two forces and, in particular, noting their
ages, we see the following table which demonstrates the numbers and ages of the
ships. For this purpose, a modern (at
the time) ship is considered one which was built post-1930. Note not only the numbers of the two fleets
but also the relative degree of modernity.

It is understood that various combat losses afflicted both
fleets but for the purpose of this post, that is immaterial.
One aspect that jumps out from this comparison is the ages
of the two fleets. The German fleet is
significantly more modern than the British, many of whose ships are obsolete or
nearly so. This makes the comparative
strength much more even than a simple numerical comparison would suggest.
However, there is more to the table. Recall that the UK had worldwide commitments
and ?half? of the British naval strength was dispersed
around the world.
If we arbitrarily divide the British fleet size in half to
account for the large, worldwide dispersion we get the following comparative
table.

At this point, we see that the effective, local strength of
the RN was roughly comparable to the local German strength and the German fleet
retains the age advantage. Further, we
note the overwhelming German advantage in submarines.
The historical question, then, becomes, what could the
German navy have done to take advantage of this roughly comparable size comparison
and actual advantage in age?
Well, some possible operations might have included:
Destroy the British
Home Fleet using combined surface navy and submarines. There are any number of ways the Home Fleet
could have enticed/coerced into a decisive fleet battle. For example, a surface ship sortie against
British ports along the English Channel would likely have sufficed to draw out
the Home Fleet. The larger point is that
a major German surface action, coordinated with multiple wolf packs of
submarines could have decimated the Home Fleet.
Blockade British
ports to seal off convoys. There
would have been no need to try to destroy convoys at sea if they can be
prevented from unloading at their destination ports. It would have been much easier to seal
British ports with mines and submarines than to try to find and engage convoys
at sea. The closer distance to the
U-boat’s home ports would have also facilitated the support efforts for the
submarines.
Seal the English
Channel. Had the German U-boats and
E-boats been concentrated in the English Channel, it could have been sealed off
with fairly minimal effort and resources.
Combined with mining, both ends could have been sealed thereby allowing
the Germans to conduct cross channel naval bombardments, raids, and,
ultimately, a cross channel invasion, all unhindered by English naval forces.
Bombard English
coastal ports/cities. The German
surface navy could have devastated British ports, again, denying British
resupply efforts.
Prevent the D-Day
build up. As we discussed in a
previous post, the Germans could have prevented the Allied assault at Normandy
by attacking the ports, camps, depots, etc. that were necessary for the Allied
invasion effort.

Bismarck and Tirpitz - Operate As A Massed Force |
Admittedly, all of these efforts would have required the
support of the German air force but, early in the war, this was not only
possible but the German air forces would have enjoyed parity, if not
superiority, in aircraft performance. By
coordinating their efforts, the German navy could have operated with air cover
and eliminated air bases and radar stations on or near the coast. In turn, the German aircraft could have
benefited from the concentrated anti-aircraft fire of the German ships.
What was not a good operational use was solitary commerce raiding. The
allies had, for all practical purposes, an infinite supply of merchant ships.
Sinking a handful was not going to impact the war. In a similar vein, the submarine attacks on convoys was a hopeless effort. The German submarine fleet could have been much more effectively employed, as described above.
The point of this post is not to discuss what specific
missions the German navy could have or should have performed but to examine how
Germany used its navy, what it could have done differently, and what lessons
their actions, or lack thereof, offer us today.
So, what lessons can we take from this that apply to us,
today? Consider these:
Fleet In Being –
Some historical observers have claimed that Germany’s surface fleet was most useful as a ‘feet in being’ by tying up Allied resources. Is
this true? Absolutely not! The point of
a military is to destroy the opponent's assets, not make them consume renewable resources.
The allies, supported by the industrial might of America, had an infinite
amount of resources, for all practical purposes. The Germans needed to use
their naval forces to impose operational and strategic defeats on the allies -
which they failed to do or even attempt to any great degree. This should serve as an important lesson as
we contemplate war with China and their resources. Our Navy cannot become a ‘fleet in being’,
unwilling to engage and unwilling to seek victory. We must become offensive-minded as opposed to
our current defensive mindset. This
starts with building a fleet that is cheap enough to risk in combat. A $15B+ carrier is not an asset anyone is
going to risk. Billion dollar destroyers
are not expendable assets. And so on. Currently, we have a 'fleet in being' rather than a combat fleet.
Solitary Ships Will Be
Destroyed - Distributed force cannot succeed unless the sensing and communications
network works flawlessly and the massing of firepower can be achieved. Even then, the individual ships are subject
to defeat in detail. Germany’s commerce
raiders demonstrated this. Before we
irreversibly commit to distributed lethality (if we haven’t already), we need
to seriously wargame the concept of distributed operations using realistic
conditions, not scripted games skewed to support a pre-determined conclusion. We need to be 100% sure that distributed
operations will work and I am certain that any realistic and unbiased
assessment will demonstrate the folly of such operations. History conclusively supports this. The handful of distributed operations that
were conducted in WWII pretty much uniformly resulted in disaster.
Offense – “The
seat of purpose is on the land.” This
adage is the fundamental truth for navies but is too often lost in the
fascination with ship-to-ship battles. Navies
exist to support land operations and they do that by conducting offensive
operations oriented toward impact on land.
The Germans forgot this and never made any serious effort to support the
strategic land operations and never made any serious attempt to conduct
offensive operations.
Our Navy, today, is almost exclusively focused on defensive
operations. Consider the small,
anti-ship Marine units. Those aren’t
offensive, they’re purely defensive.
Consider our aircraft – they’re short ranged, defensive assets intended
to protect the fleet. Consider our major
surface ship, the Burke. It’s main
purpose is defensive anti-air warfare.
Consider our entire Marine Corps which has devolved from a middle
weight, amphibious offensive force to a lightweight, defensive force. Consider our major weapons development
efforts like ballistic missile defense, Standard SM-6 anti-air missiles, LCS
ASW and MCM which are defensive in nature, an FFG(X) which is supposedly
focused on ASW and AAW, both defensive in nature. Where’s our long range, hard hitting new
weapons? There essentially aren’t
any. We’re a defensive Navy.
Summary
Germany had a reasonable powerful and numerous fleet – or could
have – that was squandered in piecemeal fashion. Does this sound ominously like our current
plans for distributed lethality? WWII
demonstrated that lone ships, or small groups of ships, are subject to defeat
in detail and modern missile warfare will only exacerbate this trend. Naval survival and victory will go to the
side that can mass both offensive and defensive firepower. Too many people, including the US Navy,
forget about the need for defensive firepower as a mandatory adjunct to
offensive operations. We need to abandon
the fantasy of a few scattered units bringing a powerful enemy to their knees
through the magic of networking. Instead, we need to refocus on single purpose,
powerful, survivable, ships that can conduct offensive operations in large
groups.
