All too often, today,
requirements are downgraded and then rationalized to explain why the downgrade
wasn’t actually a downgrade. Wake
up! Yes, it was a downgrade. Of course it was a downgrade.
Consider the highest level
military requirement that sets the priorities, force structures, acquisition
programs, etc. for the services.
Originally, after the collapse of the Soviet Union , the requirement was to be able to fight and win two
major regional wars simultaneously. That
has since been watered down to being able to win one regional conflict and
holding in another.
The 1997 Quadrennial Defense
Review put it this way,
“As a global power with worldwide interests, it is
imperative that the United States now and for the foreseeable future be able to
deter and defeat large-scale, cross-border aggression in two distant theaters
in overlapping time frames, preferably in concert with regional allies.
Maintaining this core capability is central to credibly deterring
opportunism—that is, to avoiding a situation in which an aggressor in one
region might be tempted to take advantage when U.S. forces are
heavily committed elsewhere… “
Despite that straightforward
statement, we have downgraded the requirement to fighting one regional conflict
and holding on in another and have rationalized that it’s a good thing. Why did we downgrade the requirement? It wasn’t because the threats decreased. It was simply because our military spending
was becoming greater and providing less return than in the past. Since we could no longer afford the force
structure required to simultaneously fight and win two major regional wars we
opted to change the requirement rather than change our procurement and spending
habits.
Or, consider the Navy’s
carrier requirements. After the Cold War,
the requirement was for 15 carriers. It
has subsequently worked its way down to 11 with serious discussions about
permanent reductions to 8-10. Our need
hasn’t changed. What’s changed is that
carriers are pricing themselves out of existence, slowly but surely. Each step of the way, the Navy rationalized
the reductions.
Or, consider the Marine’s
requirement for amphibious lift.
Depending on the source, the requirement is as high as 54 amphibious
ships. Another common number is 38. The Marines have “bargained” with the Navy
and settled on 33-34 as sufficient. The
actual number is 30 ships. The Marines
and Navy have rationalized the reductions every step of the way. Again, the requirements didn’t change – only
our ability to meet them changed so we rationalized our acquisition failure.
The point is that downgrades
are imposed by outside factors, budget being chief among them although
stupidity is also right up there, and then rationalization is applied to make
the downgrade seem palatable or even beneficial and preferred. Rationalization does not, however, change the
underlying facts of the matter or the requirements. If we needed 15 carriers, we probably still
do. If we needed to be able to fight and
win two major regional conflicts at the same time, we probably still do.
Well, that sets the stage
for our discussion of survivability.
By the end of WWII, we
pretty thoroughly understood what ship survivability meant and how to achieve
it. BuShips set the standards and
ensured that new construction met those standards. Now, BuShips is gone and accounting trumps
survivability.
For decades, survivability
has been defined by a very concise and crystal clear document, OpNavInst 9070.1,
issued from the CNO’s office on 23-Sep-1988 . It is a remarkable document
characterized by fundamental, concise, and obvious statements of
requirement. For example, the basic need
is acknowledged by the statement,
“Survivability shall be considered a fundamental
design requirement of no less significance than other inherent ship characteristics,
such as weight and stability margins, maneuverability, structural integrity and
combat systems capability.”
Clear. Simple.
Obvious. So, too, is this
statement.
“Ship protection features, such as armor, shielding
and signature reduction, together with installed equipment hardened to appropriate
standards, constitute a minimum
baseline of survivability.” [emphasis added]
The document goes on to
define three levels of survivability in short, simple, and unambiguous terms.
Level I
(lowest) represents the least severe environment anticipated and excludes the
need for enhanced survivability for designated ship classes to sustain
operations in the immediate area of an engaged Battle Group or in the general
war-at-sea region. In — this category, the minimum design capability required
shall, in addition to the inherent sea keeping mission, provide for EMP and
shock hardening, individual protection for CBR, including decontamination
stations, the DC/FF capability to control and recover from conflagrations and
include the ability to operate in a high latitude environment.
Level II
(middle) represents an increase of severity to include the ability for
sustained operations when in support of a Battle Group and in the general
war-at-sea area. This level shall provide the ability for sustained combat
operations following weapons impact. Capabilities shall include the
requirements of Level I plus primary and support system redundancy, collective protection
system, improved structural integrity and subdivision, fragmentation
protection, signature reduction, conventional and nuclear blast protection and
nuclear hardening.
Level III (highest) the most severe environment projected for combatant Battle
Groups, shall include the requirements of Level II plus the ability to deal
with the broad degrading effects of damage from anti-ship cruise missiles
(ASCMS), torpedoes and mines.
The document even defines
which ships shall have which level of survivability.
Ship
Type Level
Aircraft
Carriers III
Surface
Combatants III
Frigates
and Amphibious Warfare II
Underway
Replenishment Ships II
Patrol
Combatant and Mine Warfare I
Strategic
Sealift I
Support
Ships I
All
Other Auxiliary Ships/Craft I
Clear. Simple.
Obvious.
This should be the end of
the story. However, the Navy ran into a
little problem: the LCS. The LCS was designed with a sub-Level I
survivability. The Navy claimed that it
was designed with some made up Level I+ survivability but we already totally
debunked that. The Navy flat out lied
about that. In any event, because they
made the claim of survivability that was untrue and because the ship was
designed with sub-Level I, the Navy received much criticism and bad publicity. They fought the negative perception (the
reality, actually) for years but could not overcome the criticism especially
because their own policy, OpNavInst 9070.1 contradicted their claims and showed
that the LCS should have been built with Level II.
Eventually, after fighting a
losing battle for many years, the Navy decided that if they couldn’t defend
their claims, the easiest solution was to change the survivability standards so
that the LCS would meet the new, downgraded standards and the conversation
would end. To that end, the Navy made up
a new survivability “standard” which is documented in OpNavInst 9070.1A and was
issued by CNO Greenert on 13-Sep-2012 .
The new document takes a
previously simple, clear, straightforward, and logical requirement and turns it
into a nearly incomprehensible mishmash of generic and interlocking statements
that offer no specific guidance or requirements. It has reduced a very specific process to a
vague collection of “feelings” about survivability. That was, I believe, its intended purpose –
to so obscure the survivability issue that the Navy can now claim the LCS meets
the “standard”.
The document incorporates
aspects that have nothing to do with survivability. For example, it introduces cyberwarfare as an
element of survivability. Cyberwarfare
and cyber vulnerabilities may affect a platform’s ability to accomplish its
task but it is not a survivability issue.
Even the very definition of
survivability is flawed. Read it.
“Survivability. A measure of both the capability of
the ship, mission critical systems, and crew to perform assigned warfare
missions, and of the protection provided to the crew to prevent serious injury
or death.”
This definition is incorrect
and has nothing to do with survivability.
The measure of the ability to perform missions is not
survivability. Ability to perform
missions is effectiveness. Even the
protection for the crew is only somewhat related to survivability. Survivability is, pure and simple, the
ability of the ship to remain afloat in the face of combat and damage. The Navy can’t even define survivability!
The document then goes on to
list three principal disciplines of survivability: susceptibility,
vulnerability, and recoverability. The
subsequent definitions of these disciplines are as flawed and irrelevant as the
definition of survivability. I won’t
even bother quoting them. You can read
the document if you’re interested.
Ultimately, the document
goes on to offer tables and flowcharts of survivability, none of which offer
any concrete requirements. Everything is
fluid. Survivability can be anything you
want it to be. This takes today’s “feel
good” movement and codifies it in Navy documents.
We’ve taken a perfectly
simple, logical, and useful survivability requirement, downgraded it to the
point of uselessness, and rationalized it under some all-encompassing
assessment that has little to do with survivability. Why?
Because the Navy got tired of continually defending an expensive and
non-survivable ship.
If you can’t change the
survivability of the ship, change the definition of survivability! A typical Navy solution.
Nice post CNO. I think this is where you are at your best, hoisting the Navy upon its own documentation.
ReplyDeleteWhile I was reading this it came to me that in my mind, the Navy has always built 'tough' ships. By that I mean if you go back in history, from the Standard Battleships all the way to the Constitution, a ships ability to stay afloat in the face of combat and damage for its main ship types was a key design element (I exclude wooden hulled PT's, etc.).
To the point where often our ships would be more balanced than others. The Standards may have been a few knots slower, but they were very well protected. We did have some exceptions (showboat comes to mind) but those were more exceptions based on expedience and need than design.
Now that appears to be greatly diminished. With the LCS they didn't even try.
It might be, in some circumstances, okay to do that. The PT boats were like the glass jawed puncher. THey could hit hard and were hard to hit, but hit them once and they're done. The streetfighter concepts were similar.
But the Navy, and I hate this, took the LCS and spoke out of both sides of their mouth. 'Its like streetfighter. Its littoral. Despite the fact that its 3500 tons its not a frigate'
and before you know it its doing frigate roles, and being called a defacto frigate.
It would be like putting a hull plug and depth charges on a PT and calling it a DE.
Again. If this is the new Navy, in my opinion, start throttling the budget. I have no problem spending money for well designed, tough new ships. I'm very annoyed at spending millions on badge engineering and failed concepts.
The thing about smaller PT boats and fast attack craft is that their size is a big advantage too. Small boats are hard to hit with anti-shipping missiles and can often dodge larger guns.
DeleteThats quite true, but back then even big ships were hard to hit, and relied on salvo fire. Even the number of naval ships hit by torpedoes but didnt sink was quite high- thats when survivability and a motivated crew meant the difference between sinking or staying afloat.
DeleteBritish light cruisers were badly designed so that without immediate counter flooding , a torpedo hit that was survivable, meant they quickly capsized.
Nowdays the targeting is so much better with a continuously computed impact point for shell fire , combined with air bursts, mean small boats are especially vulnerable. As well smaller missiles can mean a fast boat can be effectively hit by a helicopter
"Nowdays the targeting is so much better with a continuously computed impact point for shell fire , combined with air bursts, mean small boats are especially vulnerable."
DeleteDo you have any evidence, whatsoever, to support your contention? This is a commonly repeated claim that lacks any supporting data. In fact, the available data suggests the opposite conclusion.
I agree that theory suggests small boats are at greater risk from naval gunfire today but the reality would seem to indicate otherwise.
Give me some evidence to believe you!
The evidence against is the Vincennes incident with nearly a hundred 5" rounds fired at Boghammer size craft and no recorded hits. Further evidence is the Gulf of Tonkin battle in which around 300 rounds were fired at NV small craft with no verifiable hits. To be fair, it's not entirely certain that there were any actual targets.
The Vincennes was scrapped some 5 years ago and the incidents you mention are almost 30 years ago. That doesnt reflect the reality of modern FCS
DeleteThis is the capabilities of the SAAB CMS for a frigate and below sized vessel.

This is their FCS brochure which I have based my views on.

Naturally they dont spell out exact features and it is a 'brochure' but they are a successful company with a number of platforms. Their EOS trageting system is especially interesting
I have previously linked to youtube and the 57mm firing with timed airburst to create a moving barrage.
Thats was obviously a demonstration and there was some speculation that armoured boats, with armoured crew in the very rough seas could be invulnerable. Theres is no evidence of that but no system is perfect of course.
"I have previously linked to youtube and the 57mm firing with timed airburst to create a moving barrage."
DeleteIf you could do so again I'd be appreciative
I've looked and every example I've found of a cannon engaging a small boat has been an embarrassing failure.
Ztev, if your evidence is nothing more than manufacturer's claims than you have nothing to contribute to this discussion. I won't bother listing the litany of manf's claims that have been proven to be unfounded.
DeleteYoutube videos of staged tests could not be more unrealistic and most actually demonstrate the lack of effectiveness of guns if one knows enough to analyze the videos critically.
If you have no evidence (and I'm not aware of the existence of any), simply say so.
This day and age there is no excuse for naval guns incapable of engaging surface targets. If we can illuminate a boat with radar, it should be a very simple firing solution to hit it with a gun or missile.
DeleteWe can knock mortar rounds out of the air with a CIWS, there is no excuse for a 57mm gun, much-less a 5" gun that is incapable of hitting boats.
The big problem I see is getting a firing solution on a small boat and taking them out before they can launch an AShM at you.
ROE damn sure comes into play with this also, if a ship has to visually identify an enemy before firing on it, they will already be close enough to launch at you. You can hope that defensive systems are in full-automatic mode but they likely will not be for the same ROE.
Mat, I think you're overestimating (or overcrediting) the accuracy of guns today. Every Youtube video I see of naval gunnery exercises show a remarkable number of misses (my guesstimate is 90%+ misses judged from the splash patterns) and this is despite contrived, perfect conditions where the firing platform is barely moving and the target is often stationary or barely moving. Co-incidentally, I just watched a video of a Phalanx CIWS firing on a target small boat motoring back and forth and after several firing episodes the boat was still motoring along, speed unchanged, and the CIWS had achieved perhaps 1-5% hits, judging by the splash patterns. Moreover, the splash patterns were not tight little groups but were spread out over a hundred feet, perhaps, for each firing group.
DeleteThe reality is that the challenge of firing from a moving, unstable platform at another moving, bouncing platform is difficult and the results would only be worse if the firing platform was moving at full speed and conducting high turn rate evasive maneuvers as a real ship would in combat and the if the small boat target were boring straight in as it would in combat.
So, while you say there's no excuse for not hitting a target boat, the reality is that it's a very difficult thing to do. The videos pretty much prove it. Watch them with a critical eye and you'll see what I'm talking about.
The USN has just completed testing of SPQ-9B radar with periscope detection upgrade.
DeleteThe SPQ-9B radar is used with the Mk160 GFCS to provide targeting information for the Mk45 Gun ( among others)
http://alert5.com/2016/03/23/usn-testing-anspq-9b-with-periscope-detection-capability/
So we have the mast mounted radar detecting a periscope and then Mk160 GFCS directing gunfire at the target.
"So we have the mast mounted radar detecting a periscope and then Mk160 GFCS directing gunfire at the target."
DeleteBut they still arent hitting!!!!
A CIWS fires over a thousand rounds at a small fragile target, even if only 1% hit, it is more than enough to destroy sensors, control surfaces, or possibly even the warhead.
10 20mm rounds wont destroy a boat.
Just curious, but what would a heavily armored ship be classified as hypothetically? A level 4? Then would battleship level armor be perhaps a level 5?
ReplyDeleteEven by the middle of WW1, new battleship protection had concentrated on torpedo hits and mines. Shell fire could be protected against to some extent, but that was negated by the use of dive bombing and the bombs kept getting bigger.
DeleteA battleship would simply be Level III. There is no higher level. The levels are not defined by the amount of armor. They're defined by the ability to continue functioning in the three defined scenarios.
DeleteI've been out for some time, but back in the day our peacetime Navy did nothing for crew protection. With Poly Khakis known to melt to the skin. Look at pictures from WW II where crews donned goggles, helmets and reflective gear. Do our sailors wear fireproof nomex, and why not light helmets like hockey players? An update here from someone in the fleet would be nice.
DeleteIn no way should this be construed as defence of the Navy, but...
DeleteIn the second world war, the biggest hitter in the game was a 1200kg shell
Today, Russias biggest hitter is a 7000kg missile, which can add a nuclear tip.
Theres little excuse for a ship to be as vulnerable to small arms as modern warships are, but there are pretty hard limits as to what can be done to defend against a ton of high explosives flying at 600 miles per hour.
TrT, you may be missing the main point of survivability. It's not, as so many seem to think, the attempt to make a ship invulnerable to a given weapon. As you point out, beyond a certain, fairly small, caliber, it's not possible to provide invulnerability. Instead, survivability is intended to maximize the ship's ability to TAKE A HIT and keep afloat and keep fighting. The required survivability features include armor, certainly, but also, redundancy, separation of key components, reserve power, firefighting, reserve buoyancy, compartmentalization, damage control manpower (usually ignored today), etc.
DeleteToo many people (including the Navy) are ignoring survivability in ship design just because we can't provide invulnerability against a nuclear warhead.
I hope this helps make clear what survivability is really about.
IIRC the Navy was surprised at how many ships survived getting nuked in the tests after WWII. Whatever else those ships were tough. (Admittedly, everyone inside would have died, the ships themselves weren't direclty hit...)
DeleteIf you haven't, you should read "Neptune's Inferno". It describes the naval battles of Guadalcanal. The beating that those ships took was unbelievable. It makes you realize that the one-hit wonders we're building today are an evolutionary naval mistake of the highest order.
DeleteRedundant fire mains, power, local controls, I can get behind.
DeleteAnd trust me, when the shrapnel starts flying you'll also get behind armor!
DeleteI've done posts on armor because, frankly, most people fail to grasp the purpose of armor. While it would be great if we could develop armor that could laugh at a 2000 lb warhead, the reality is that we can't. What armor gets us is the ability to contain and minimize, to the extent possible, the area of damage from a hit. While armor might not totally stop the hit, it might protect the fire control computer and allow the ship to keep fighting. It might save the lives of the damage control party that then saves the ship. It might prevent shrapnel from shredding the fire main. It might limit the damage to one compartment instead of two. And so on. THAT'S the value and purpose of armor.

ReplyDeleteIt appears that no longer do we have command priorities fight move float but have morphed into feel good, look good (???) and keep the bean counters happy.....
ReplyDeleteI realize this is a bit old...
ReplyDelete...but last week I was able to visit CV10 and the USS Laffey in Charleston.
I didn't know the Laffey's story. But here was a 3500 ton (full load, I believe) vessel that got hit with 4 bombs, 6 kamikaze strikes, and was strafed mercilessly, and still was able to make her way back to base.
IIRC the Sumners were unarmored with conventional belt or deck armor. She's only got a 41ft beam.
But she had something like 300 men on her and they were able to do amazing damage control.
I have to also believe that even without normal 'armor' this bath built ship was very tightly put together.
You need to understand what constitutes "armor". WWII Fletcher class destroyers (and presumably these were the same) had 1/2" - 3/4" plate AS THEIR NORMAL HULL PLATE. That's so far beyond what an LCS or even a Burke has.
DeleteYou might want to investigate HY80/HY100 and STS to begin to appreciate how WWII ships were built even without add-on armor.
I will. After reading how well the Laffey took the beating I'm fascinated by just how strong materials and good construction technique can make the boat tougher. When I say 'unarmored' I meant that she didn't have a belt or deck armor. But her very construction sounds like it would be considered 'armor' today. The bulkheads were able to resist and redirect the blasts of the bombs and the kamikaze's.
ReplyDeleteWhat really shocks me is that they were able to do all this within 3500 tons full load (Paper full load weight, I'm not sure how much these destroyers would displace in full combat rig at the end of the war...everything seemed to get weighed down more). What on earth makes the lightly built LCS displace so much?
Compare that to the LCS and its just laughable. The Sumners weren't slow ships by any stretch, either. Not LCS fast but not slow.
Finally, on top of all that Wiki reports that the hull price for the Sumners was 8 million. That translates to ~108 million today. Dear God!
I'm going to sit here and stew in frustration for a bit.
Also, check out this old post which shows the damage to Cole as a function of differing steel strakes.
DeleteArmor
I saw that. That's actually one of the first posts on this blog that I remember reading. Its astounding. I wonder what the Cole would have looked like with the hole skin being HY80.
ReplyDeleteThe thing that did hit me though is that perhaps building a ship with HY-80 is too cost prohibitive. Its only built by one or two mills (one company) that I can tell.
However, previous sub hulls (Prior to Permit, I think) were all HY-43. And the Laffey certainly didn't have HY-80. So maybe if HY-80 is cost prohibitive we could just go back to the 1/2" - 3/4" plate of the old style destroyers.
It seems a pretty simple way to up survivability.
And again, I'm really confused now. The LCS weighs as much as a Sumner at full load. The LCS is made of aluminum and thin steel, to a largely civilian spec. The Sumner was made of thicker plates of steel, to a military spec.
The hull sizes are pretty close.
The Sumners had to include provisions for 300 odd men and bunkerage for a 6000nm range.
The LCS is including provision for maybe 100 men when you include mission modules, and bunkerage for between 1200/3000(?) nm range.
Where the hell is all the weight in the LCS coming from?
For one thing, the beam of the LCS is 17 ft wider than the Sumner. That's a lot of extra ship! Multiply 17 ft x the 370 ft length of the ship and that's a huge amount of additional "ship". Of course, that simple calc isn't right because the ship isn't uniformly 17 ft wider for the entire length but you get the idea.
DeleteAlso, look at the superstructure dimensions and volume. The LCS superstructure covers the entire (17 ft wider) deck area. The Sumner superstructure is tiny by comparison. The LCS carriers a comparatively HUGE superstructure.
Okay. That makes sense. That would be alot of steel. I wonder if the LCS has so much more beam due to its semi-planing nature.
DeleteOne could make the argument that the Sumner wouldn't stand up to a Brahmos, and so any extra effort is useless. But I don't quite understand that.
A Sumner wouldn't stand up to a Tone class cruiser either. But it doesn't mean its not a good idea to make it as stout as possible.
For a ship going in Harms Way it just seems to make sense.
All that extra superstructure also makes for center of gravity stability issues which the LCS, PREDICTABLY, has. I've documented that the Navy's own module swapping tests in which they practiced moving 15,000 lb loads around (simulating a module container, I guess) revealed that even small movements resulted in the ship exceeding the allowable incline limits (stability). It was right around that time that the Navy began backing away from the swapping concept. You'll notice that the Navy doesn't even claim to be able to swap module anymore other than during a special drydock availability. LCS's, if they ever finalize modules, will be given a module and never swap it unless under extraordinary circumstances - that's the Navy's new position not merely my opinion.
DeleteThe LCS superstructure also eliminates much of the horizontal deck space that was present on WWII ships. Look at a WWII destroyer and note all the horizontal deck space - space which mounted all kinds of guns and gear. Now look at the LCS. Where would you put an extra gun if you wanted? There's no horizontal space available. What little there is, is high up on the top of the superstructure which raises the center of gravity and worsens the stability problem.
DeleteAs you begin to carefully analyze the LCS from a naval engineering perspective, you begin to realize how badly flawed the design is from a basic, fundamental naval architecture perspective. No amount of upgrades or weapons additions (where will they put them and what will they have to remove to retain weight and stability margins?) can overcome a fundamentally flawed design.
My main objection to the LCS is less what it is or is not equipped with but, rather, the fundamental flaws that are designed in and can't be overcome.
OK, actually my main objection is the lack of a CONOPS but my second objection is the fundamentals which is the point of this comment.
"OK, actually my main objection is the lack of a CONOPS but my second objection is the fundamentals which is the point of this comment."
ReplyDeleteI'm guessing that one leads to the other, or at least contributes. Without a CONOPS you don't have an occams razor to say 'That's a bad idea for this ships mission'.
" LCS's, if they ever finalize modules, will be given a module and never swap it unless under extraordinary circumstances - that's the Navy's new position not merely my opinion."
That is my main argument against some folks who love the LCS. One guy (who, honestly, was a small ship sailor, so I have to give him some cred over me) blatantly said he likes the LCS because he likes the concept of modularity, and doesn't want to see the LCS cancelled because it would hurt that concept.
But the LCS is *so* terrible at the modularity even if you like the concept. If I was 100% on board I'd still dislike the LCS because it would be like me being an advocate for V8's and having an automaker come out with a 130hp engine that gets 5mpg. Sure, it has the V8 I want, but its going to perform so horribly that it will give a bad representation to everyone who tries to use it.
