US Navy Plans to Triple the Amount of Missiles per Submarine
The Navy will soon finish initially prototyping new weapons tubes for its Virginia-Class submarines designed to massively increase missile firepower, bring the platform well into future decades and increase the range of payloads launched or fired from the attack boats.
The new missile tubes, called the Virginia Payload Modules, will rev up the submarines’ Tomahawk missile firing ability from 12 to 40 by adding an additional 28 payload tubes – more than tripling the offensive strike capability of the platforms.

US Developing 'Quietest and Least-Detectable Sub' in the World
The United States is developing "the quietest and least-detectable submarine in the history of the world," Kris Osborn wrote for Scout Warrior, citing senior service officials. The first Columbia-class sub to be produced under the Ohio Replacement Program is expected to enter service in 2031.

Of course it's the quietest since it won't enter the water till 2031.

These jokes are serious when it comes to such chest thumping BS from Uncle Scam. These media propaganda mouthpieces make it sound like submarine
noise levels can be engineered arbitrarily low. This is pure uneducated drivel. We are in the era of diminishing returns (aka on the asymptote) for given size
of nuclear submarine. The hull will vibrate just from interaction with the ocean gyres and waves (subsurface, they do exist just like in the atmosphere).
Anything with a propeller requires shafts and gears which cannot be willy nilly made quieter than the "enemy".
The noise level of Soviet submarines has always been exaggerated by Uncle Scam and his NATO minions. At the same time the quietness of US submarines
has been hyped beyond reason as we have seen on this board where people have posted dB numbers that would make US submarines quieter than the
ocean background noise (i.e. a claim retarded to the nth degree). There is a reason for building subsea detection nets and it ain't the "excessive noise" level
of Russian submarines.

If they're actually serious about reducing noise levels, then the obvious solution would be to build dramatically much smaller. So instead of 20 SLBM's per sub, 2-4 SLBM's per sub means you can build much smaller, cheaper, you can cover a much larger area of the oceans.

Re: US Nuclear Submarine Force
US Navy Missile Submarine Gets Go-Ahead
WASHINGTON -- The program to build a new class of nuclear-powered ballistic missile submarines for the US Navy passed a major procedural hurdle Jan. 4, the US Navy announced Monday, allowing engineers and designers to move to the detail design portion of the effort.
The Milestone B approval was granted by Pentagon acquisition chief Frank Kendall for the Columbia-class program, previously known as the Ohio Class Replacement (ORP) and as SSBN(X).
The US plans to design and build 12 Columbia-class submarines for a total acquisition cost of $100 billion – as measured in 2017 dollars – or $128 billion, as measured in total year dollars through the program, which stretches into the mid-2030s.
In a statement, Columbia program director Capt. David Goggins declared “the Navy is committed to delivering Columbia on time and within budget while taking advantage of every opportunity to achieve further cost savings.”
The official tally for the acquisition cost has been baselined at $100 billion, pegged to the year of the Milestone B review.
With that approval, the Columbia class moves to the engineering and manufacturing development (EMD) phase of the program. The first ship is scheduled to be ordered in 2021.
“Milestone B enables the program to move into the Engineering and Manufacturing Development phase where we will focus our attention on achieving an 83 percent design maturity prior to construction start in 2021,” Goggins said in the statement, adding that the next phase will be a production readiness review.
General Dynamics Electric Boat is the Columbia program’s prime contractor. The shipbuilder, with shipyards at Quonset Point, Rhode Island and Groton, Connecticut, is expected to grow its workforce from 14,000 to 18,000 employees to build the Columbias while continuing to build Virginia-class attack submarines.
Huntington Ingalls Industries Newport News Shipbuilding, GD’s 50-50 partner in building the Virginia class, will built roughly a third of each Columbia.
The Columbia’s name was officially announced Dec. 14 and will carry hull designation SSBN 826. Follow-on ships of the class will be designated SSBN 827 through 837.
US ballistic missile submarines carry the Trident D5 weapon with nuclear warheads. The Lockheed Martin-built missile will also arm Britain’s new Successor-class submarines, now known as the Dreadnought-class after the name of the first ship.
The Navy expects the Columbia to carry out its first deterrent patrol during fiscal 2031.

Re: US Nuclear Submarine Force
HAhahahaa... hilarious.... so it says that Russian subs are 80% of what US subs were 30 years ago during the cold war...
The big upgrade for the new virginia class sub is an extra vertical launch tube bin with 6 extra missiles over the standard two bins with 12 missiles.
So these super american subs will carry 18 subsonic cruise missiles and that will make them so sophisticated and powerful.
Yasen class Russian subs carry 32 tubes for either long range subsonic cruise missiles or supersonic rocket powered anti sub missiles, or supersonic anti ship missiles.
They talk about 2020-2025... by then the Russian subs will be carrying Mach 8 hypersonic Zircon anti ship missiles... perhaps that will make them 50% of US subs from WWII maybe.
What a load of crap.

Re: US Nuclear Submarine Force
Actually, they said russians are 80% of what they (russians and not US) were during cold war. And they are wright because compared to the more than 300 subs that soviet navy had, russia is not as much powerfull as the soviet navy even if in terms of technology they are better than in the 80s.
The smaller number of vessels means less time in the sea to control other nations.
It is like the strategic patrol that resumed in 2007 because they couldn t sustain the effort before that.
But if they do what they say they will do, get gorshkovs and more SSN, that will change.

Re: US Nuclear Submarine Force
If that is what they were trying to say then they are still wrong.
During the cold war the at sea rate of the Soviet sub force was tiny.... less than 25%.
Now they have far fewer subs but they are vastly more active...
And one presumes as their numbers increase their activities will also increase too.

Yeah they are more active but 25% of more than 300 subs is huge and they had much more big ships that were sailing around the world.
But the goals were not the same. Russia doesn't need to defend communist government around the world, just defend their interst and borders so it's a pointless discussion to compare them.

Problems with US submarine production
The Columbia class submarines that cost about $6 billion each are experiencing welding issues. That is really a massive fail for the US.
BTW, this is a generic problem in North America. Various governments kill off funding for research projects resulting in the dissolution
of the researchers into retirement and private sector or other research areas. The idiots who control the purse strings think that
these defunded projects can be restarted with the press of a button. That's not what happens in real life and we see this in the
failing skill levels of the workers that were gathered to build the new generation of US submarines. There was no continuity in the
workforce training since all the skilled welders were dumped decades ago and never mentored the new generation.

Re: US Nuclear Submarine Force
US Navy awards contract for new Block V Virginia-class submarines
The US Navy has awarded a $22bn contract to General Dynamics Electric Boat (GDEB) and its partner Huntington Ingalls Industries’ Newport News Shipbuilding division (HII-NNS) for the construction of nine new Block V Virginia-class submarines.
The multi-year procurement contract covers the period from 2019 to 2023. It is said to be the largest ever shipbuilding contract awarded by the US Navy.
GDEB is the prime contractor for the Block V Virginia-class programme. The company is building the submarines under a teaming agreement with subcontractor HII-NNS.
The contract requires Electric Boat and Newport News Shipbuilding to deliver eight of the ships fitted with the Virginia Payload Module (VPM), which will enable a three-fold increase in the missile strike capacity of the Virginia-class ships.
The VPM provides increased payload space through the addition of a mid-body section.
It will add four large payload tubes, with each capable of carrying and launching seven Tomahawk missiles.
The contract also includes an option for a tenth Block V submarine with VPM. If the US Navy exercises the option, the total value of the contract could increase by an additional $2bn.
General Dynamics Electric Boat president Kevin Graney said: “This contract allows for our shipbuilding team, our suppliers and our employees to plan ahead so that we can continue to deliver submarines of unmatched quality, stealth and lethality.
“Increasing the cadence of our production from one per year to two, coupled with the start of full production of the Columbia-class ballistic missile submarine, represents a generational increase in submarine production for our nation.”
GDEB and Newport News have so far delivered 18 boats of the Virginia-class to the US Navy.
The companies are currently building ten Block IV variants of the submarine for the navy and will undertake deliveries of the Block V boats between 2025 and 2029.
US Navy Submarines programme executive officer rear admiral David Goggins said: “Block V Virginias and Virginia Payload Module are a generational leap in submarine capability for the navy. These design changes will enable the fleet to maintain our nation’s undersea dominance.”
The navy is buying fewer Block V boats than the 11 originally planned.

Re: US Nuclear Submarine Force
The Pentagon signed the largest contract for new nuclear powered ships
It is worth adding that, according to American experts, although it has not yet been officially confirmed, the design of the VPM module provides the possibility of its adaptation for the deployment of long-range ballistic missiles armed with promising hypersonic gliding warheads. Such missiles, as well as the indicated warheads, are currently being developed in the United States as part of an interspecific program with the leading role of the US Ground Forces.
If this information is confirmed, then new Virginia-type submarines from multipurpose submarines with missile and torpedo weapons designed to combat enemy submarines and surface ships and deliver selective attacks on its targets on land will turn into a kind of underwater mini-strategists capable of to solve problems of a truly strategic scale. However, so far all this can only be considered purely in a hypothetical plan, and whether this idea will be realized in practice is still a very big question. Moreover, the work on the hypersonic warhead has not yet reached the finish line.

Re: US Nuclear Submarine Force
American shipyards also have problems and delay repair of US submarines
https://bmpd.livejournal.com/4022151.html
Problems Repairing American Nuclear Submarines
According to the U.S. Navy, the Los Angeles type nuclear submarine SSN 764 Boise of Los Angeles type (in service since 1992) again arrived from its Norfolk base at Newport News Shipbuilding (part of Huntington Ingalls Industries Corporation) in Newport -News (Virginia) for medium repairs (Engineered Overhaul - EOH). The boat has been waiting for repairs to begin for more than five years.
The nuclear submarine Boise returned from its last military service at the beginning of 2015, and after that it was planned for production in medium repairs. In February 2017, a ban on diving was introduced for the boat and after that she defended in Norfolk.
In 2017, the U.S. Navy signed a contract with Newport News Shipbuilding in the amount of $ 385.7 million for an average repair of the Boise EON boat. On June 18, 2018, Boise arrived for repair at Newport News, but the shipyard was not able to start repairing it due to delaying the repair of other boats of the same type (SSN 725 Helena and SSN 762 Columbus), and as a result, Boise was in March 2019 forced to retire to Norfolk.
Now Boise is trying to re-stand on repair at Newport News.
Newport News systematically breaks the deadlines for repairs of all three of the above-mentioned nuclear submarines of the US Navy, which causes numerous complaints from the US Navy. The reason is, in particular, the lack of experience in such repairs and the lack of qualified personnel at the shipyard, despite the fact that more than 1,200 people were involved in the repair of the Helena and Columbus nuclear submarines in 2019.
Four state shipyards that repair nuclear submarines of the US Navy are also facing similar problems. According to the report of the U.S. Government Accountability Office (GAO), issued in 2018, since 2008, repairs of almost all U.S. Navy submarines have been carried out either with a delay in the start of the planned dates for their implementation, or with delaying the repair dates themselves.
In an attempt to solve this problem, the U.S. Navy resorted to setting up boats for repair at private shipyards, including Newport News Shipbuilding, but there, problems with repairs were also reproduced on a similar scale. Newport News, which has received contracts for the repair of these three boats, has delayed the delivery of Helena (despite the fact that it carried out repairs in the amount of current, not average) and Columbus and for three years can not start repairs at Boise. The Helena nuclear submarine arrived at Newport News in October 2017 and was due to be commissioned in 2018, but only left the shipyard in the spring of 2020, making room for Boise.
Repair of the SSN 765 Montpelier nuclear submarine at the General Dynamics Electric Boats shipyard in Groton is being delayed in a similar way.
The standard repair time for EON should be 25 months, however, as you can understand, in recent years this period has not been systematically maintained.
In total, from 1976 to 1996, the U.S. Navy commissioned 62 Los Angeles-type multipurpose submarines, of which 40 are now in the fleet.

I image you would mean high-tensile corrosive resistant steel.
Well i would read this article that you have mentioned, because i have the feeling that you have confused the problem of the flooding in the market of very cheap low-grade steel by part of Korean and Turkish firms ( a problem that has hit much harder European and ,even more, US corporations of the sector) with production of military shipbuilding high-tensile alloy steel.
You well know ,i image, that the performance level (for tensile strength, plasticity, weldability, and salt and cold resistance ) of domestic Federation synthesis of HTS was always historically and is still today totally unmatched at world level; with the technological gap with foreign firms even fast widening, with the design and production of new nitrogenic steel by part of ЦНИИ КМ "Прометей", therefore Federation Navy couldn't import military grade steel from foreign firms simply because they cannot offer nothing today even at the level of half of '80 years domestically, simple like that Laughing
Just for a clear comparison with some often cited over ocean corresponding products : a Virginia submarine is made today with HY-80 HTS steel (with an yield stregth of 550 MPa) that is inferior to the 1954 "Прометей" designed AK-25 (580 MPa and incomparably better weldability and plasticity) !
Even the other mostly used over ocean high stength steel alloy HY-100 (yield strength of 690 MPa ) is not competitive with 1972 synthetised AK-33 - used ,at example, for pr.949, 949A (yield strength of 785 MPa) or AK-32, used for pr. 971, (yield strength of 985 MPa).
Even theirs most advanced effectively synthetised high tensile strength steel alloy product , having practically not achieved any real military production employment, the HY-130 (yield strength of 896 MPa) is terribly obsolete and underperforming not only against the cited AK-32 but against the more modern AK-34 ( yield strength of 1177 MPa ) or latest AK-35 and AK-36 (classified, but from projection superior to 1300 MPa).
As you can realize to create surface ships or submarines of marine grade steel incomparably superior to those of the most up-to-date surface and under-surface units now in water or in construction by part of over ocean companies, domestic manufacturers could employ old reserve stocks, in air-proof sealed sites, of Ak-32 and AB-2 steel.
The problem is only that this kind of product, for its physical characteristics crushingly superior to those employed today by foreign shipbuilding industry, is evaluated terribly obsolete by domestic standard.

U.S. submarines were made of substandard steel
The leading supplier of the US Navy was implicated in the scandal with the sale of low-quality metal for the construction of nuclear submarines. The falsification of ship steel research results lasted for decades.
Bradken Inc. - The main supplier of high-grade metal at the Electric Boat and Newport News Shipbuilding, which builds nuclear submarines for the U.S. Navy, paid $ 10.9 million under a deferred prosecution agreement, writes AP citing the United States Department of Justice. In 2008, the company bought a metallurgical plant in Tacoma. Nine years later, when changing the management of the enterprise, it was found that the former director of the plant, 66-year-old Elaine Thomas, since the 1990s had faked the results of an analysis of 240 steel batches for submarine hulls - this is half of all the metal supplied by Bradken for the needs of the US Navy.
Thomas pleaded guilty and said that she considered "stupid requirements" to conduct metal tests at such low temperatures. Her trial will begin on June 30.
- Bradken Inc. threatened the operations of the US Navy and the lives of sailors, ”said Seattle Attorney Brian Moran. Although the investigation documents do not mention accidents caused by the low quality of the metal, Moran believes that the Navy incurred additional costs for the combat readiness of maintaining the submarines. What kind of submarines in question are not reported.
After the fraud opened, the company actively collaborated with law enforcement agencies and pledged to tighten control over the factory laboratory. If Bradken complies with the Ministry of Justice, the company’s charge of fraud will be dropped.

So US subs have been supplied with faulty sub-standard steel for 3 decades? Absolutely hilarious!
