(See) SSBN(X) - Columbia-Klasse
#1
Der Bau einer neuen Klasse von atomar angetriebenen, strategischen Raketen-U-Schiffen für die US-Marine hat, relativ unbemerkt, im Oktober 2020 begonnen, als die erste Einheit (SSBN-826 Columbia) auf Kiel gelegt wurde. Diese neue Klasse von U-Schiffen (zunächst SSBN(X) bzw. nun Columbia-Klasse genannt) wird die im Einsatz stehenden strategischen U-Schiffe der bekannten Ohio-Klasse ergänzen und irgendwann ganz ablösen. Die rund 20.000 Tonnen großen Einheiten werden vsl. ab ca. 2027 der US-Marine zugehen. Bislang ist der Bau von 12 Schiffen geplant.
Zitat:Huntington Ingalls contracted in support of construction on first two Columbia-class submarine

Huntington Ingalls Industries, America’s largest military shipbuilding company has announced that its Newport News Shipbuilding division has been awarded a contract modification from General Dynamics Electric Boat in support of construction on the first two Columbia-class ballistic missile submarines.

As noted by the company, the contract modification, valued at approximately $2.2 billion, provides continued design support efforts, as well as the construction and delivery of six module sections for each of the first two Columbia-class submarines.

As part of the contract, Newport News will deliver the completed modules to Electric Boat for final assembly. The contracted module delivery dates are scheduled to start in November 2022 with the last module delivery taking place by January 2028. [...] The Columbia class will replace the fleet of Ohio-class ballistic missile submarines. The lead ship is scheduled to be delivered to the Navy in 2027.

Zitat:Report to Congress on Columbia-class Ballistic Missile Submarine Program

The Navy’s Columbia (SSBN-826) class ballistic missile submarine (SSBN) program is a program to design and build a class of 12 new SSBNs to replace the Navy’s current force of 14 aging Ohio-class SSBNs. The Navy has identified the Columbia-class program as the Navy’s top priority program. The Navy procured the first Columbia-class boat in FY2021 and wants to procure the second boat in the class in FY2024. The Navy’s proposed FY2021 budget requested the procurement of the lead boat, as well as $4,014.7 million (i.e., about $4.0 billion) in procurement and advance procurement (AP) funding and $397.3 million in research and development funding for the program. The Department of Energy’s (DOE’s) proposed FY2021 budget requested an additional $64.7 million in DOE development funding for the program. Congress, as part of its action on the Navy’s FY2021 budget, authorized the procurement of the lead boat and provided $4,122.2 million in procurement and AP funding and $397.3 million in research and development funding for the program. [...]

The Navy’s FY2021 budget submission estimates the procurement cost of the first Columbia-class boat at $14,393.4 million (i.e., about $14.4 billion) in then-year dollars, including $6,007.8 million (i.e., about $6.0 billion) in costs for plans, meaning (essentially) the detail design/nonrecurring engineering (DD/NRE) costs for the Columbia class. [...] The Navy’s FY2021 budget submission estimates the total procurement cost of a 12-ship class at $109.8 billion in then-year dollars.

Als Ergänzung zu meinem Post am 02.06.: Und schon gibt es die erste Kostensteigerung - obwohl erst eine Einheit im Bau ist (oder vllt. gerade deswegen, weil man nun einen besseren Überblick hat und eine Neueinschätzung vornehmen konnte).
Zitat:Cost Estimates for Lead Boat in Columbia-class Program Grow by $637M

The Navy’s cost estimate for the lead ship in its new ballistic-missile submarine program grew by $637 million over the last year, according to the service’s Fiscal Year 2022 budget submission.

The estimated price for the future USS Columbia (SSBN-826), the lead ship in the class of 12 ballistic-missile submarines, is now $15.03 billion, compared to a $14.39 billion estimate in the FY 2021 submission, according to budget justification documents released late last week. [...] General Dynamics Electric Boat, the prime contractor for the Columbia-class boats, declined to comment when asked for an explanation behind the cost increase. After this story was published, a Navy spokesperson told USNI News in a statement that the cost of the first boat grew due to a new estimate.

“The budget increase is a result of the Navy funding the program to the most recent independent cost estimate,” said Lt. Cmdr. Stephanie Turo. “Ordnance costs were anticipated early in the project based on a best estimation at that time. The decrease was caused by vendor prices coming in lower than estimated.”

The Navy’s Columbia (SSBN-826) class ballistic missile submarine (SSBN) program is a program to design and build a class of 12 new SSBNs to replace the Navy’s current force of 14 aging Ohio-class SSBNs. Since 2013, the Navy has consistently identified the Columbia-class program as the Navy’s top priority program. The Navy procured the first Columbia-class boat in FY2021 and wants to procure the second boat in the class in FY2024. [...]

The Navy’s FY2022 budget submission estimates the procurement cost of the first Columbia-class boat at $15,030.5 million (i.e., about $15.0 billion) in then-year dollars, including $6,557.6 million (i.e., about $6.60 billion) in costs for plans, meaning (essentially) the detail design/nonrecurring engineering (DD/NRE) costs for the Columbia class. (It is a long-standing Navy budgetary practice to incorporate the DD/NRE costs for a new class of ship into the total procurement cost of the first ship in the class.) Excluding costs for plans, the estimated hands-on construction cost of the first ship is $8,473.0 million (i.e., about $8.5 billion). The Navy’s FY2021 budget submission estimated the total procurement cost of a 12-ship class at $109.8 billion in then-year dollars.

Zitat:CNO Warns Columbia-class Sub Would Miss Delivery Under a Year-Long Continuing Resolution

A year-long continuing resolution would force the Navy to miss deadlines on delivering the first Columbia class ballistic missile submarine, the service’s top officer told House appropriators Wednesday.

In prepared testimony on Columbia, Chief of Naval Operations Adm. Mike Gilday told the panel that “since the shipbuilding account is uniquely line-item appropriated, the CR provides insufficient funding for SSBN-826, our first Columbia-class ballistic missile submarine and number one modernization priority. … If the CR is extended over the full year, we expect construction delays to the Columbia-class program and costs to grow, increasing delivery risk to this critical system and threatening our ability to meet U.S. Strategic Command requirements. This is a program with zero margin for delays.” [...]

“In a flat account, we have to do something” and that means scaling back recruiting and delaying permanent change of station moves for starters to cover the pay raise, said Mike McCord, the Pentagon comptroller. He said holding defense spending to last year’s level would be $8 billion below what other congressional committees have approved for the Fiscal Year 2022 budget.

“We’ve been slowly boiling this pig” of using continuing resolutions over approving a new budget for 20 years. McCord said the impact of a year-long continuing resolution, which had never happened before, would translate to $24 billion not spent on recruiting and retention, needed research and development and new programs, training exercises and eroded away by inflation in continuing operations and programs.

Zitat:First Columbia Ballistic Missile Submarine Begins to Take Shape

NORTH KINGSTOWN, R.I. – The backbone of the Navy’s next nuclear ballistic missile submarine is starting to take shape in a series of understated white buildings on the edge of Narragansett Bay. Building-sized sections of the future USS Columbia (SSBN-826) have been under construction at the General Dynamics Electric Boat facility at Quonset Point, under cover from the Rhode Island winter and largely unseen due to the COVID-19 pandemic. [...] While carrying eight fewer nuclear missiles than its predecessor, Columbia will be longer, heavier and feature a complex electric drive propulsion system and associated technology to keep the class relevant for the 50-year lifespan of the boomer.

“Columbia is a 20,000-ton submarine. It’s the largest, most complex submarine that’s ever been built,” Chief of Naval Operations Adm. Mike Gilday told USNI News in an interview en route to the construction facility.

The $110 billion Columbia program and the VPM addition are refining techniques EB developed for the construction of the early Virginia-class submarines to maximize the efficiency of assembling the complex hulls under the pressure of a timeline with razor-thin margins.
