Zitat:Assessment of Damaged Attack Boat USS Connecticut Begins in Guam

The U.S. nuclear attack boat that hit an underwater object in the South China Sea on Oct. 2 is now in Guam undergoing an assessment and preliminary repairs in the midst of two investigations into the incident, Navy officials confirmed to USNI News on Sunday. USS Connecticut (SSN-22) arrived at Naval Base Guam on Friday after almost a week sailing on the surface of the Pacific from the South China Sea. [...]

After arriving in Guam, two of the 11 sailors who were injured when the collision occurred were treated ashore and returned to the attack boat. No additional details of what Connecticut hit in the South China Sea have been made public. Chinese officials have demanded additional details about the incident. USNI News understands that it was not another vessel.

Zitat:Navy Not Sure What USS Connecticut Struck in the South China Sea, Beijing Accuses U.S. of Cover-Up

The U.S. Navy still isn’t positive what one of its most powerful attack submarines hit in the South China Sea, as repair assessments continue in Guam, four sources familiar with the results of the preliminary investigations told USNI News this week. [...]

As of Tuesday afternoon, the undersea object that damaged the forward section of USS Connecticut (SSN-22) had not been definitively determined as part of several investigations into the Oct. 2 incident, the sources said. Early indications were Connecticut hit a seamount in the South China Sea, two defense officials familiar with the Navy’s examination of the submarines told USNI News, but that has not been confirmed by investigators. Politico first reported earlier this month that the boat may have hit an undersea feature. [...]

The impact to the forward part of the attack submarine damaged the submarine’s forward ballast tanks and forced the boat to make a week-long trip on the surface to Guam, two defense officials told USNI News this week. [...] Since returning to Guam, the boat is still under evaluation for the scope of repairs by Naval Sea Systems Command, personnel from the Puget Sound Naval Shipyard and submarine tender USS Emory S. Land (AS-39), Fields told USNI News on Tuesday.

Zitat:US Navy sacks commanding officers of crashed submarine

The US Navy has sacked three top crew members aboard a nuclear submarine that crashed into an underwater mountain.

Commander Cameron Aljilani and two others were removed after an investigation into the incident in the disputed South China Sea. The USS Connecticut struck the object last month, forcing the vessel to come to the surface for a week and sail to the US territory of Guam. Navy officials say the crew members "could have prevented" the collision. Last week, the navy said the submarine had hit an uncharted "seamount" while patrolling below the surface. [...]

Fifteen sailors suffered minor injuries. The submarine is currently being checked for damage at Guam in the Pacific before it returns to Washington for repairs. [...] Ryan Ramsey, a former British Royal Navy submarine captain, said he was shocked by the collision, which is relatively rare. "The USS Connecticut is a very modern submarine - so it's kind of surprising," he told the BBC. "But if you relax at any point, then things can happen."

Zitat:USS Connecticut Pulls Into San Diego After Surface Transit From Guam

Attack submarine USS Connecticut (SSN-22) pulled into San Diego, Calif., Sunday morning after transiting the Pacific Ocean on the surface due to damage from a collision in the South China Sea. Ship spotter WarshipCam first posted a photo of the Seawolf-class attack submarine pulling into the San Diego harbor early Sunday. [...] The boat’s sonar dome became inoperable as a result of the collision, making it unsafe to travel underwater.

Connecticut struck an unmapped seamount in early October in the South China Sea, a collision that damaged the ballast tanks and the forward section of the boat, USNI News previously reported. After hitting the seamount, the boat sailed on the surface to Guam, arriving on Oct. 8 for initial repairs and a damage assessment. The submarine left Guam at some point last month.

Zitat:Huntington Ingalls Launches The Newest Virginia-Class Submarine

Huntington Ingalls announced on 28 April that Virginia-class submarine New Jersey (SSN 796) was recently launched into the James River at the company’s Newport News Shipbuilding division. [...] The 7,800-ton submarine, which had been in a floating dry dock since being transferred from a construction facility in March, was submerged and moved by tugboats to the shipyard’s submarine pier for final outfitting, testing, and crew certification. [...]

The Block III submarines are fitted with the new Virginia Payload Tubes designed to lower costs and increase missile-firing payload possibilities. The first 10 Block I and Block II Virginia-class submarines have 12 individual 21-inch diameter vertical launch tubes able to fire Tomahawk Land Attack Missiles (TLAMS). The Block III submarines are built with two larger 87-inch diameter tubes able to house six TLAMS each.

Zitat:US Navy's Virginia class program of nuclear powered submarines in trouble

According to a report published by the US Congressional Research Service on July 27, 2022, the Virginia class program experienced cost growth in its early years and delays relative to targeted delivery dates. [...] This comes after Australia's previous defense minister, Mr Dutton, said on 13 June 2022 that his plan was to buy two Virginia-class submarines from the US by 2030. [...]

The Virginia class, also known as the SSN-774 class, is a class of nuclear-powered cruise missile fast-attack submarines, in service in the United States Navy.

They are designed to excel in anti-submarine warfare, anti-ship warfare, strike warfare, special operations, intelligence, surveillance and reconnaissance, irregular warfare, and mine warfare. Fast-attack submarines project power ashore with special operations forces and Tomahawk cruise missiles in the prevention or preparation of regional crises.

Zitat:U.S. Navy To Get New Unique Submarine: Virginia SSW

The USS Jimmy Carter is widely regarded as the most secretive submarine in the U.S. Navy. It is especially equipped for Seabed Warfare, unreported missions deep below the waves. Now a new seabed warfare submarine, using a Virginia Class hull, is planned. [...]

A single Mod VA SSW (Modified Virginia, Subsea and Seabed Warfare) version of the Virginia Class is expected to be built. Work is already underway at the famous Electric Boat shipyard in Groton, Connecticut. A basic outline of the design was shared by General Dynamics Electric Boat’s President, Kevin Graney, in a January 2022 at a Connecticut Economic Summit in 2022. Since then some information about the SSW design has slowly emerged in open sources, but naturally the details remain cloaked. According to the Congressional Research Service, a single boat will be procured in the U.S. Navy’s 2024 budget. The calculated cost is $ 5.1 billion, almost a billion more than the baseline Virginia Class. [...]

Seabed warfare has been brought into sharp focus by Russia’s ongoing efforts to map undersea infrastructure. And by the September 2022 with the attack on the Nord Stream gas pipelines in the Baltic. [...] Extract details of the new Virginia SSW submarine are, as we should expect, unclear. Even the USS Jimmy Carter which has been in service almost 20 years remains something of a mystery. However we can expect the new submarine to carry specialist uncrewed underwater vehicles (UUVs), remote operated vehicles (ROVs) and special operations submersibles.

https://www.navalnews.com/naval-news/202...ginia-ssw/

Sehr interessantes Schiff - also die Carter -, welches bereits bei Indienstnahme eine Multi-Mission-Plattform erhielt, so zur Unterbringung von 30 bis 40 Spezialkräften und 2 bis 3 ROVs. Und es soll sich auch (anscheinend) eine Art von internem "Dock" zwecks der Unterwasser-Reparatur von Glasfaserkabeln an Bord befinden. Man kann von ausgehen, dass das neue SSW dies mit Sicherheit auch haben wird.

Zitat:USS Oregon attack submarine receives post-delivery servicing

The Block IV Virginia-class attack submarine was recently delivered to the US Navy, and the platform will now undergo servicing. [...]

The work follows the vessel’s change of command in April this year, from commander Lacy Lodmell to commander John Ross. Before this, the vessel was the 20th Virgina-class SSN to be delivered to the US Navy, and the second Block IV unit of this variant, in February 2022. [...] Block IV Virginia-class submarines incorporate design changes focused on reduced total ownership cost. By making these smaller-scale design changes to increase the component-level lifecycle of the submarine, the Navy will increase the periodicity between depot maintenance availabilities and increase the number of deployments.

Blocks I-III Virginia-class submarines are planned to undergo four depot maintenance availabilities and conduct 14 deployments. Block IV design changes are intended to reduce planned availabilities by one to three, and increase deployments to 15.

Zitat:Diminishing returns: the US Navy’s attack boat availability problem

A report from the US Congressional Research Service has outlined the current state of SSN availability across the UN Navy’s subsurface fleet. [...]

The US Navy (USN) had 31 of 49 nuclear-powered attack submarines (SSN) available for operations in FY2023, with the 18 remaining vessels either in maintenance or idle awaiting their turn in a shipyard, according to a report by the US Congressional Research Service (CRS). [...]

In total, 37% of the USN’s SSN fleet was unavailable for operations in FY2023, with 14 boats listed as undergoing maintenance and four vessels described as “idle” and still to undergo depot maintenance. [...] The ratio of active SSNs to those undergoing maintenance or idle is significantly worse compared to FY2015, which saw just 19% of the force unavailable for operations from a fleet of 53 boats. [...]

However, the USN’s fleet of SSNs could be reduced by up to 10% in the early-2030s should approval be given by the US Congress for the sales of three Virginia-class SSNs to Australia under the AUKUS SSN programme, with a further two boats on option.

Zitat:Navy Will Ask for 1 Virginia-Class Sub in FY 25 Shipbuilding Budget, Increase Amphib Production

THE PENTAGON – The Navy’s Fiscal Year 2025 budget will ask Congress to fund one Virginia-class attack boat, a break from a steady two-per-year demand signal from the service and a sign that industry is still catching up to the current demand, three sources familiar with the proposed budget submission confirmed to USNI News. While the Navy plans to only ask for one Virginia attack boat, the request will include one submarine’s worth of advanced procurement materials to maintain demand for the limited amount of suppliers for submarines, the sources confirmed to USNI News this week. [...]

The U.S. is set to sell three to five Virginia-class boats to Australia. But to do this, submarine manufacturers HII’s Newport News Shipbuilding and General Dynamics Electric Boat would have to build 2.33 boats a year. HII builds the bows and sterns for the Virginia boats and Electric Boat builds the central hull around the reactors. The pair have a similar teaming arrangement for the Columbia-class nuclear ballistic missile submarine.

Zitat:US Navy christens latest Virginia-class submarine, the future USS Idaho

The Virginia class is the mainstay of the US Navy’s subsurface attack fleet, although the latest Presidential Budget Request for FY2025 only called for a single submarine to be funded. [...] According to a US Department of Defense (DoD) release on 15 March, the submarine, which began construction in 2017, will be the 26th Virginia-class fast attack submarine and the fifth USN ship to be christened with the name Idaho, which ironically is a land-locked US state.

The last USN ship named Idaho was battleship BB 42, commissioned in 1919.
