marauder2048 said:One of the arguments is that EMALS reduces the wind-over-deck requirements to the point where
a conventionally powered carrier can conduct launch operations without adversely impacting its fuel
stores.
The Navy needs a vastly larger fleet — 414 warships — to win a great-power war, well above today’s 274 ships or even the Navy’s unfunded plan for 355, the think-tank MITRE calculates in a congressionally-chartered study. That ideal fleet would include:
14 aircraft carriers instead of today’s 11;
160 cruisers and destroyers instead of 84;
72 attack submarines instead of today’s 52;
New classes ranging from a missile-packed “magazine ship,” to diesel-powered submarines, to a heavy frigate to replace the Littoral Combat Ship, which would be cancelled.
marauder2048 said:I found this claim from the CSBA report curious
"To minimize the UCAV’s radar signature, it would likely have a “flying wing”
structure like a B-2 bomber or the TERN UAV (see Figure 46) that lacks traditional wings
or a tail. This design reduces the number of surfaces that can reflect radar energy, but also
reduces the aircraft’s lift and, in turn, payload or endurance. Therefore, the UCAV would not
have the very long endurance and high payload capacity desired for refueling, logistics, or
surveillance missions."

From Hyper Velocity Projectile Industry Day Notice:
- HVP BLK 0 will provide Initial Operational Capability (IOC) for the 5" MK 45 MOD 4 Gun Mount emplaced on Aegis Weapon System equipped DDG-51 Class Destroyers and CG-47 Class Cruisers.
- The US Navy is currently planning for an IOC during 4QFY23 for HVP BLK 0.
- HVP BLK 0 will provide a prime weapon foundation for future HVP capability upgrades as new platform sensors or gun launch systems are fielded by the US Navy.
- Building on previous HVP risk reduction efforts, the E&MD prime weapons vendor will define the HVP BLK 0 tactical architecture in order to meet the HVP BLK 0 Performance Specification, Interface Control Documentation, and Aegis Weapon System integration requirements.
- The US Navy is planning for contractor development of the HVP BLK 0 projectile and propelling charge as an integrated system.
- The US Navy plans to provide an HVP BLK 0 life-cycle container as GFE.
- The US Navy plans to utilize the MK 160 Fire Control System and conduct MK 45 Gun Mount Ordnance Alterations (ORDALTs) to integrate HVP BLK 0. An Interface Control Working Group (led by the US Navy) will be developed as part of the HVP BLK 0 E&MD phase in order to arrive at a final HVP BLK 0 to MK 45 Gun Mount Interface Control Document.
- The US Navy is currently conducting trade studies and analysis to finalize HVP BLK 0 requirements generation. The final HVP BLK 0 performance requirements will be detailed in a performance specification which will be released at a later date.
- The HVP BLK 0 will provide a maximum range of 26 nautical miles (nmi) or greater.

Somewhere I have Navy drawings of a non-AEGIS DDG-51 design, but it was early on and I think based around New Threat Upgrade. Basically, it was a DDG for end users who would not be allowed to buy AEGIS when it was still tightly controlled.
Problem is that it's a very expensive ship to build and run, even not including SPY-1. Four large turbines, 90+ VLS tubes, crew of 300+, roughly 9000 tons full load. (That Next navy article is pretty tricky, citing light ship displacement for the DDG with either standard of full load for the other designs).

Those are simply shipbuilding costs, not including any Government Furnished Equipment, which includes all of the combat systems, the engines, the reduction gearing, etc. Total procurement cost for a DDG is at least twice that, and only a couple hundred million is specific to AEGIS.
TomS said:Here is a cost breakdown for the DDG-51
http://www.fi-aeroweb.com/Defense/Budget-Data/FY2016/DDG-51-NAVY-SHIP-FY2016.pdf
I don't actually see the engines separately here. They may be in the main construction line after all. But you can see that Aegis only contributes about $130 million out of a final per-ship price of about $1.4 billion.
Here is the equivalent document for LCS
http://www.fi-aeroweb.com/Defense/Budget-Data/FY2016/LCS-NAVY-SHIP-FY2016.pdf
Interestingly, there are fewer separate program line items for the combat system and armament. Some of that is bought separately but here is also more rolled into the main construction contracts, it appears.

Thanks Tom! I'm just getting into these documents. I'm not following $130M for AWS? I'm looking at page 8-8 of the first document. It reads AWS was ~$253M in '14 and $627M (Qty2) in '16.

Look at the line items on 8-15. The $131 million figure is the "major hardware" line. You could add the System Integration line, which would be about $30-40 mil per ship. A lot of the rest is basically constant year-to year regardless of how many ship sets they buy, so that's really AEGIS program overhead, not specific to any single ship. Spares should be applied across the fleet, not just for the ship currently being built.
TomS said:No, I wouldn't. The spares and other overhead lines would be paid even if there was no new Aegis ship being built in a given year. Those costs aren't tied to the ship.
MITRE's future navy plan has a concept called the "Magazine Ship." The MGX would carry up to 4 railguns, 1,000 missile silos, or 96 Pershing-III intermediate range ballistic—or some mix.
Three new navy plans all are focused on more ships, with more missiles, more drones and more planes. Lethality is increased with more missiles, more planes and more drones. The total number of weapons are increased and they are put on more ships.
Adding three small carriers would double the number of planes and drones in a carrier group.
"The Construction Plans category is the second major shipbuilding segment of the cost estimate. This category includes the nonrecurring costs related to detailed construction plans and other associated engineering tasks for lead ships. Planning yard, lead yard, and follow yard costs for ship classes may also be accounted for in this category or in the Basic Construction category."NeilChapman said:--
Couple of questions for those "in the know".
1. What is included in the "PLAN COSTS"?
NeilChapman said:2. And how do "PLAN COSTS" increase from $22M to $34M in two years? These are all Flight IIA ships. I don't get it.
NeilChapman said:3. How is it that a ship you've built 40 times consistently needs ~$20M in change orders?
NeilChapman said:4. How do HM&E costs, again, on ships built 40 times, increase from $67M to ~$80M in two years?

At a guess, ESSM Block II. It's supposed to have some capability against ASBMs.
bring_it_on said:Not sure of the SM2 but the Sm6 has intercepted MRBM's, precisely in the DF-21 range class.
