Nothing with mutch rangeIsn't there some kind of containerized ground air-defense system that can be just welded to superstructure?

Nothing with mutch range
Totalitarian regime's tend not to be overconcerned about their people's survivability.While LCS gets a lot of hate, it did some things right. Small crew, minimal AAW suite, very little damage resistance. AIUI the reason to silence the ship is not that the subs will hear it, it is so the sensors have lower signal/noise to deal with. A problem that has arisen recently is antiship ballistic missiles. This raises the bar for AAW suite. Here's the proposal:
Minimal AAW suite for self defense only.
Some drone defenses.
A few canisters for antiship missiles.
Minimal battle damage resistance. Mild steel that is cheap and can be welded easily.
Small crew.
Little or no silencing.
57mm cannon so it looks like a warship.
2 helicopters.
Towed sonars that can deploy far enough from the ship so that self noise is not as much of a problem.
Enough speed to escort amphibs, logistics ships, and merchant ships. Look at commercial engines that are efficient, reliable, and have a robust spare parts supply chain.
Have systems engineers take a look and see if it's worth it to put a high end ECM suite as it can emit freely so others can survive. Maybe just a minimal self defense suite.
Nothing else. No VLS, no worrying about shallow water ASW. This is it. It's a modern Loch frigate. How long should the hull be built to last? As long as the engines can last. Crank them out in large numbers per year so the overhead costs are spread over more hulls per year. Buy in large blocks with no design changes unless a major flaw arises. Buy in multi-year block so the yards can lower their risk. When they wear out, recycle them. Take off the sensors, ECM, etc. and put them on a new vessel. Skimp on maintenance since they are disposable. It should be possible to design this hull pretty easily but it is not so they will need to use a foreign hull or a CG cutter or something. They can't even take one of those and modify it. It just has to be there and be capable of doing the above.
This is the level 1 ship.
Systems engineers can look at having a level 2 ship. What the UK calls "local area air defense", silencing, some battle damage resistance, bow sonar, good ECM, etc. Is it worth it to build these? I strongly suspect it is not, unless the level 1 ship ends up too expensive.
The level 3 ship is the Burke and they need to study a replacement. Anything over 10,000 tons is suspect, anyhting over 12 is verging on being a capital ship. How do they put a first class AAW and BMD suite on a ship and afford it?
The issue here is familiar to anyone who has read the book Kaigun by Evans and Peattie. How do you take on a superior foe with inferior resources? Everything the IJN did made it weaker. Removing armor and self sealing fuel tanks from planes, building super battleships instead of larger numbers of reasonable ships, massive torpedo batteries on DDs and CAs, Kantai Kessen, etc.
Totalitarian regime's tend not to be overconcerned about their people's survivability.
And an tendency to overrate the appearance of strength hence the building warships with appearance and " perceived status " playing a conscious role in their design and building.
I think you're going to have to do some silencing, you can hear merchant low-speed diesels at pretty significant ranges. Maybe you could get away with just Prairie/Masker, maybe rafted turbines and electric drive.Here's the proposal:

I admit, I don't know how much a bow sonar helps a surface ship, not when it's streaming one surface towed array and one VDS. A bow sonar may only matter in shallow water.Systems engineers can look at having a level 2 ship.

A first-class AAW system needs big radar arrays, especially if you want to add BMD capabilities, which means a physically large ship to carry it around stably. Look at the Japanese ASEVs, those are looking at 14,000 tonnes. The USN DDGX is looking at 13,500 tonnes. Sejong the Great class are 10-12,000 tonnes. And of course the Zumwalts are ~15,600 tonnes, IIRC mostly due to the tumblehome design for stealth.The level 3 ship is the Burke and they need to study a replacement. Anything over 10,000 tons is suspect, anyhting over 12 is verging on being a capital ship. How do they put a first class AAW and BMD suite on a ship and afford it?
2021: lengthen hull and revised bowDo we have any indication that NAVSEA changed the design requirements after contract award?
Hope that they can build some without IEP first, so we can have some mature design off to the sea quick enoughRecently I’ve been exchanging emails with a BIW lead naval architect for their F100 derivative.
If the FMM design is really dead, I think we’ll see a clean sheet program or give BIW a call.
Build some MMSCs and do LCS Lethality & Survivability Upgrades Phase II in the interim.
Spruance had a quality AA suit, too. Just not top of the line one - and realistically, top of the line suit doesn't really add much to a ship on independent missions, nor having multiple such suits is truly necessary for, say, convoy work.A modern Spruance is a mistake from the standpoint of cost effectiveness. Once the ship of sufficient quality to be a modern Spruance is built, it will cost between 1 and 2 billion dollars. Probably closer to 2. A quality AAW suite is between 300 and 500 million dollars. Once the life cycle cost is looked at, procurement cost being about 20% of life cycle cost, it makes sense to add the AAW suite so that the ship can do ASW at the top level but also be a good AAW ship.
NAVSEA does not set arbitrary length requirements, the design yard would do that to meet the pre-set mobility requirements (which they agreed to when taking the contract).2021: lengthen hull and revised bow
2022: CAPTAS-4
2023-2024: structural changes mentioned in GAO report, which increase plenty of weight
Integrating IEP would require a completely new machinery set up. At that point it’s more effective to either integrate it into Flight I, or start from scratch. Additionally, procurement history shows that “transitional ships” are not worth the effort. See the Zumwalt and Ford programs.Hope that they can build some without IEP first, so we can have some mature design off to the sea quick enough
Reading between the lines, my impression is drones, drones and more drones. It's drones all the way down, whether anyone likes it or not. There are too many positions that need to be played.
The analogy is interesting because adding the AAW suite to a Spruance gives you a modern day Kidd DDG... which is basically what the Constellation class is.A modern Spruance is a mistake from the standpoint of cost effectiveness.

The final hulls came in around $650-$700M (adjusted for inflation). This is still higher than the anticipated price point in 2003, but not as exaggerated as defense media makes it out to be. The claim they have "no real military capability" is extremely reductionist.LCS
~$400M platform
~$100M electronics and defensive weapons
No real military capability
I believe they were estimating $1.4B for the lead ship, $1.2B for series production (likely in block buys). Definitely not <$1B.FFG-62 Constellation
~$650M platform
~$300M electronics (AEGIS, EASR, VDS sonar, SEWIP etc... all domain combat capability minus BMD. Better ASW than any USN ship)
~$60M weapons (MK-41, NSM... good offensive/defensive mix)
This is a fair estimate but note it's for a block buy. A single ship, ordered independently, comes in around $3B iirc.DDG-51 Flt III
~$1.5B platform
~$700M electronics (adds AEGIS BMD + SPY-6 + full SEWIP)
~$200M weapons (more MK-41, TLAM, 5" gun)
This. Phelan is simply giving up on manned ships altogether, not finding a better way to build them faster.
Your own source points out these numbers are for block buys. I didn't say you were wrong, just that there's a few big asterisks.My numbers come straight from the Navy's own SCN (Ship Construction) budget documents.
You're right, the navy's only missions are escorting flattops in high-intensity scenarios. You're right my apologies.The limited LCS modules (NSM mainly) are not sufficient to enable it to operate in the Red Sea, let alone in a China scenario inside the first or second island chain, so it's unclear what those NSMs would be useful for. LCS certainly won't be tagging along with USN carrier strike groups or surface action groups, neither will it be capable of escorting replenishment ships or amphibs in dangerous waters (which is not a job for drones either, incidentally), so what might its military value be?
Intentional or not, weapons are underestimated by a factor of >2... even filling 96 cells and searam alone with mean loadout will cost way more than that, and this is before we add actual weapons.DDG-51 Flt III
~$1.5B platform
~$700M electronics (adds AEGIS BMD + SPY-6 + full SEWIP)
~$200M weapons (more MK-41, TLAM, 5" gun)
Same; weapon suit is underestimated by a factor of two, and that's for 1st ship. Desired ships(48 strike cells) - more like x3. Plus, of course, all of that added a lot to the platform as well.FFG-62 Constellation
~$650M platform
~$60M weapons (MK-41, NSM... good offensive/defensive mix)
Those are the weapons system costs excluding consumables. i.e. Mk-41 launchers and NSM racks without missiles.I agree with your point, but

The lengthening and the revise bow was still something more than predictedNAVSEA does not set arbitrary length requirements, the design yard would do that to meet the pre-set mobility requirements (which they agreed to when taking the contract).
CAPTAS-IV was in the original requirement list.
FMM submitted their design knowing structural changes would be required, agreed they were possible when taking the contract, and thus became responsible for them.
Erm. It got RIM-7 NSSMS with Mark 91 FCS based on two Mark 95 fire control radar. Purely self-defense kit; no real area defense capability like Perry's have. Against anything more serious than a lone Tu-95K, Spruance didn't stood a snowball in hell chance.Spruance had a quality AA suit, too.
No…The lengthening and the revise bow was still something more than predicted
Which was changed to CAPTAS-IV which has infinitely more reference material and real world application to draw from. This also ignores the VDS fits in an ISO container, with minimal impact on the ship itself. It just needs a door on the stern. If anything, this has larger impacts on the BIW submission because F100 is so cramped as is.Regarding the sonar, originally it was supposed to fit SQS-62
Which again, were outlined in the initial requires, FMM agreed were possible, and took responsibility of to deliver.With the structural changes (including the generator rooms), the Navy itself is creating more trouble than having a ready to use reliable design
It was mainly due to absolute ineptness of Royal Navy damage control teams, than any design flaws. Less than 40% of all RN saliors in 1982 have damage control training, the exercises were sporadic (and anti-smoke exercises weren't conducted at all), and officers have no clue how to organize efforts when bridge was filled with toxic smoke.Stark took 2 Exocets and stayed afloat. Similar sized British destroyers foundered in similar situations.

The Italians have constructed ships before the US as a state even existed. And even in this day and age they are one of the most prominent shipbuilders in Europe together with France. They widely export their modern designs to various navies across the globe, they build frigates, offshore patrol vessels and corvettes for countries in Europe, Asia and Africa. Fincantieri in Italy constructs everything from cruise ships, to research vessels up to modern surface combatants.If the FREMM Base couldn't do that to US Frigate Standards?
All the issues make much more sense.
The base FREMM design fails to meet survivability requirements that the Perry of all things meets. Again, NAVSEA's Level II Survivability standards are high, but not unreasonably so, and they're written in blood. Have Italian standards ever been demonstrated outside of a model basin?NAVSEA is just incompetent and trying to bring a perfectly good foreign designed vessels up to their weird standards was a doomed undertaking from the start. An undertaking that wasn't necessary anyway.
How many Americans returned home because of it?You get what you pay for and that is the issue. Is it worth it?

As the the standards issue, note that US ships involved in collisions o well, while a European frigate sank. Also, USS Cole and Stark. You get what you pay for and that is the issue. Is it worth it?
That kind of scratches the Legend class from the list of available options, doesn't it."Earlier this year, the service halted construction on two of the four OPCs that Eastern Shipbuilding was under contract to deliver as part of the first phase, and the schedule for the first ship is delayed by five years, according to GAO."
OPC and NSC aren’t the same ship, or being built in the same yard…That kind of scratches the Legend class from the list of available options, doesn't it.
At that point just buy more LCSs. It’s 80% the capability for a few hundred million less.NSC is probably fine for a NDRF for convoys. The problem would be finding the personnel to staff the ships. European survivability standards are adequate for an optionally manned robotic picket, too, but nothing you want to put people inside.
NAVSEA lost design capability for more than 20 years. Who should take responsibility for it? I don't know. Back to WW II, under the supervision of SCB, BuShip designed a lot of warship schedules. Maybe Nimitz class(SCB-250) is the last warship that designed by USN itself?NAVSEA is just incompetent and trying to bring a perfectly good foreign designed vessels up to their weird standards was a doomed undertaking from the start.
