In July 2007 Christopher P. Cavas reported in Navy Times that the Center for Naval Analyses Analysis of Alternatives (AoA) may recommend two different ships to form the CG(X) program. "One ship would be a 14,000-ton derivative of the DDG 1000, an "escort cruiser," to protect aircraft carrier strike groups. The vessel would keep the tumblehome hull of the DDG 1000 and its gas turbine power plant. The other new cruiser would be a much larger, 25,000-ton nuclear-powered ship with a more conventional flared bow, optimized for the ballistic missile defense (BMD) mission. In all, five large CGN(X) ships and 14 escort cruisers would be built to fulfill the cruiser requirement in the Navy's 30-year, 313-ship plan, which calls for replacing today's CG 47 Ticonderoga-class Aegis cruisers and adding a specially designed sea-based missile defense force."

Pre BCA..those were the days... ;)

The reference to the SM6 is vague and it does not carry over to the schedule shared later (Tomahawk does). Also,

The Advanced Gun Systems will remain on the ships, but in an inactive status for future use, when a gun round that can affordably meet the desired capability is developed and fielded.

No news on whatever that ammunition will actually be? I know there was talk of a modified Excalibur. Maybe the Italians would try up-scaling their Vulcano?

Excalibur and Vulcano options were not funded. The only way they end up on the ship in the near future is if Raytheon or Leonardo agree to eat all the integration and testing costs, even then you'd have to convince the DoD to actually buy the stuff. The HVP in an AGS sabot may or may not have had it's funding zeroed as well. They're leaving open the possibility of getting new rounds in a future budget, but for now the AGS only has the existing stockpile for testing the guns and then they'll essentially go into stasis.

The Navy did buy some Vulcano and PGK-Aft rounds for testing on the 5 inch guns.
But per Moose's remarks, the NRE costs for adapting them for AGS are probably
prohibitive for six tubes.

Sea-launched cruise missile could be deployed on surface ships, potentially DDG-1000s

February 16, 2018 | Justin Doubleday

The Pentagon is considering deploying a new nuclear-tipped, sea-launched cruise missile on surface ships such
as the Zumwalt-class destroyers as well as submarines, according to the head of U.S. Strategic Command.

Air Force Gen. John Hyten said the Defense Department's fiscal year 2019 budget request includes tasking to look
at platforms for carrying the new weapon. The Trump administration's recently unveiled Nuclear Posture Review
calls for developing the SLCM to provide the U.S. military with a "flexible," low-yield nuclear capability.

Though many have assumed the SLCM would only be deployed on submarines, Hyten said surface options could
include the Navy's new Zumwalt-class destroyers (DDG-1000). The service only plans to build three such ships.

"It's important to note the NPR, when it talks about the sea-launched cruise missile, it does not say 'submarine-launched,'"
he said during a Feb. 16 NPR policy summit at National Defense University in Washington. "It says sea-launched, because
we want to look at a number of options, everything from surface, DDG-1000s, into submarines, different types of submarines,
fast attack submarines, [guided-missile submarines], [ballistic-missile submarines], look across those boards and make
sure we know what it is."

If that info about the HVP only having a 2 lb bursting charge is correct it doesn't even seem suitable for naval gunfire support. I know they're talking about the HVP doing other things like engage aircraft or missiles though, maybe that's all it's intended for.

Maybe they're going about this in the wrong order for the 155mm AGS and should concentrate on unguided ballistic-trajectory ammunition first. At least that would give the guns something to shoot.

From the EA on the HVP:

Kinetic energy dispensing variant, which would be used against air targets. This variant
would contain 0.2 pound (0.1 kilogram) of explosives to burst the casing of the
projectile and dispense tungsten pellets.

GD Bath Iron Works Delivered the future USS Michael Monsoor (DDG 1001) to the US Navy

Posted On Wednesday, 25 April 2018 09:31

The U.S. Navy accepted hull, mechanical and electrical (HM&E) delivery of the future USS Michael Monsoor (DDG 1001) from shipbuilder General Dynamics Bath Iron Works (BIW) April 24.

Delivery of DDG 1001 follows extensive tests, trials and demonstrations of the ship's HM&E systems, including the boat handling, anchor and mooring systems as well as major demonstrations of the damage control, ballasting, navigation and communications systems.

"Delivery of DDG 1001 marks the culmination of years of dedication and hard work from our Navy and industry team," said Capt. Kevin Smith, DDG 1000 program manager, Program Executive Office, Ships. "We have incorporated many lessons learned from DDG 1000 and are proud of the end result. DDG 1001 will be a tremendous asset to the Navy."

The 610-foot, wave-piercing tumblehome ship design provides a wide array of advancements. The shape of the superstructure and the arrangement of its antennas significantly reduce radar cross section, making the ship less visible to enemy radars.

Like the first ship of the class, USS Zumwalt (DDG 1000), DDG 1001 employs an innovative and highly survivable integrated power system (IPS), distributing 1,000 volts of direct current across the ship. The IPS's unique architectural capabilities include the ability to allocate all 78 megawatts of installed power to propulsion, ship's service and combat system loads from the same gas turbine prime movers based on operational requirements.

DDG 1000-class ships are delivered through a two-phase approach in which combat systems are installed and activated subsequent to HM&E delivery. Following HM&E delivery, Michael Monsoor will transit to its homeport in San Diego, California, for commissioning in January 2019 and to begin combat systems activation, testing and trials.

DDG 1001 is the second ship of the Zumwalt class. The third and final ship of the class, the future USS Lyndon B. Johnson (DDG 1002), is currently in construction at BIW's shipyard along with Arleigh Burke-class destroyers Daniel Inouye (DDG 118), Carl M. Levin (DDG 120) and John Basilone (DDG 122).

From GAO's "WEAPON SYSTEMS ANNUAL ASSESSMENT" April 2018 (my highlights).
If the Zumwalt hull ends up forming a baseline for the CG, it's imperative that additional units are purchased to bridge the gap until Cruiser buys start. Every year of gap will just make the process of re-starting that much more problematic.

This would appear to be unobtainium, might as well bring the cruiser requirement forward but that would have to be new money which is unlikely.
