China May Have Tested a new Sub Launched Nuclear Missile

China conducted the first test flight of its next-generation JL-3 submarine-launched ballistic missile (SLBM) in late November, according to report published on the Washington Free Beacon website on 18 December.

Citing unnamed defence officials, the test firing was detected by US missile-launch warning satellites and monitored by US intelligence agencies.

Russia to Build at Least two More Borey-A SSBNs by 2027

According to an industry source, quoted in the Russian media, the 2018-2027 State Armament Program includes construction of two additional Project 955A/Borey-A submarines. This will bring the number of submarines of the Project 955 class to ten by 2028. The source said that five submarines will be based in the Northern Fleet and five - in the Pacific. He also suggested that the construction of the Borey submarines will continue after 2027, since it is unlikely that the Project 667BDRM subs will be able to remain in service that long. (Back in May 2018, it was suggested that Russia may build six additional Project 955A submarines, bringing the total to 14.)

India's First Ballistic Missile Submarine Conducted its First Nuclear Deterrent Patrol

When Indian Prime Minister Narendra Modi announced earlier this month that the Indian Navy had completed its first sea-based nuclear deterrent patrol it was more of a statement of intent than a demonstration of a new capability.

The Indian Navy’s new ballistic missile submarine (SSBN) INS Arihant was the boomer that completed the month-long deterrent patrol. Whilst this is not insignificant – it is the first country outside of the five members of the U.N. Security Council to develop this capability – it also shows how far away India is to achieve its goal of joining the other great powers in establishing a credible sea-based deterrent.

Only the U.S., U.K., France and Russia can sustain continuous-at-sea deterrent patrols, which a provides continuous launch capability of a submarine-launched ballistic missile (SLBM) by maintaining at least one SSBN on station at any one time that could fire a nuclear missile. A continuous patrol requires a minimum of four SSBNs.

The patrol as a statement will have more effect in diplomatic circles than in military ones. India wants to join the club of countries that can support a sea-based deterrent and eventually achieve a continuous at-sea nuclear deterrent. It also means India will have the ability to launch all three air, land and sea-based types of nuclear weapons and a more robust second strike capability.

New Russian Sub Launched Nuclear Missile has Entered Service




Russian press quotes a source in the industry as saying that the Bulava SLBM has been finally accepted for service. That was a long wait.

The work on the Bulava program started almost exactly 20 years ago. It was included in the plan that was approved in 1998, when Russia was struggling to find the way to maintain its strategic forces not much below the START II levels of 3500 warheads - at that point it was expected that START II will come into force. It wasn't an easy process and the MITT emerged with two projects in its portfolio - the Topol-M (which will later become Yars) ICBM and the Bulava SLBM. The R-39UTTH Bark SLBM project - a follow-up to R-39/SS-N-20 - was cancelled after three failed flight tests. Part of MITT's argument was that Bulava will use Topol-M technologies and therefore will be cheaper to produce.

Russia Will Launch 4th Borei Nuclear Missile Sub in November

The first advanced version of the nuclear-powered ballistic missile submarine Project 955A Borei-class (North Wind) – the Knyaz Vladimir (Prince Vladimir) – will be floated out this coming November, Commander-in-Chief of the Russian Navy, Admiral Vladimir Korolev, said in an interview with the Krasnaya Zvezda newspaper.

“In the near future, the Severodvinsk-based Sevmash Shipyard will float out a new nuclear-powered missile underwater cruiser, the Knyaz Vladimir, from the slipway. The event will take place in November,” he said.

Korolev earlier said that the fourth Borei-class boomer was supposed to have been floated out in August.

The Knyaz Vladimir was laid down in 2012 and will become the fourth submarine in the series of eight Borei-class underwater cruisers and the first submarine of the advanced Borei-A Project.

India Will Lease Another Akula Class SSN From Russia

New Delhi has furthered its plans to lease another Russian nuclear-powered attack submarine (SSN) for the Indian Navy (IN) for around 10 years at a cost of around USD1.5-2 billion.

Official sources told IHS Jane's that Moscow and New Delhi agreed at this year's India-Russia summit in Goa on 15 October that India would lease a half-built 8,140-tonne Project 971 'Akula'-class boat from 2021-22 onwards, the completion and sea trials of which India would finance.

Construction of the proposed SSN is said to have been suspended in the early 1990s following the break-up of the Soviet Union, as happened to the submarine formerly known as Nerpa (K 152): the SSN that entered IN service in April 2012 under the name INS Chakra on a 10-year lease for around USD962 million.

Is India Going to Lease Yasen Class Nuclear Submarines From Russia?

A high-level Indian delegation will be visiting Russia shortly to finalize an agreement on renting the Yasen class submarine for the Indian Navy. Government sources told Sputnik that renting the second nuclear powered attack submarine from Russia would result in the introduction of newer technology into India, which would eventually pave the way for Russian collaboration with India for it program to build six new SSN.

The US Navy Wants a Very Long Range Torpedo

The attack submarine is one of the dangerous naval combatants in the world owing to its stealth and ship-killing torpedoes. But limited range has long been the torpedo’s major drawback. Unlike a missile which travels through the thin atmosphere, a torpedo must fight harder to reach its target.

As a result, navies spend billions of dollars finding ways to prevent hunter-killers from getting close to their valuable surface ships. And to give their own submarines a better shot, they find ways to add range.

Now the U.S. Navy is researching how to significantly boost the range of its torpedoes starting with the Mark 48, according to an August request for information from the Office of Naval Research. If successful, America’s subs could get a lot more lethal.

Ohio Replacement SSBN to be Named Columbia Class

The Navy’s new planned class of ballistic missile submarines will be named in honor of the District of Columbia, two Navy officials confirmed to USNI News on Thursday.

According to a notification memo to Congress obtained by USNI News, the first ship in the next planned class of Navy nuclear ballistic missile submarines (SSBN(X))– also known as the Ohio replacement program — will be named USS Columbia.

Secretary of the Navy Ray Mabus’ office is not releasing further information until the naming announcement, one Navy official told USNI News.

While the name Columbia for a U.S. ships and aircraft is not new – at least eight U.S. ships, a Space Shuttle and the Apollo 11 command module have all shared the name – it will be the first time the name has been used to commemorate the U.S. capital, the sources told USNI News.

The fleet’s current USS Columbia (SSN-771) – a Los Angeles attack submarine – is named in honor of Columbia, S.C., Columbia, Ill and Columbia, Mo. The submarine is expected to decommission before the first SSBN(X) enters service.

US Navy Nuclear Submarine Plans

Got subs? The Navy sounds increasingly confident it can squeeze an extra submarine into its construction plans. The additional Virginia-class attack sub, to be funded in the 2021 budget, would enter service just as the attack submarine force shrinks to historic lows while Chinese and Russian fleets grow in both numbers and sophistication.

The Navy had planned to cut back production of Virginias, which carry conventional cruise missiles and torpedoes, to make room for the much larger Ohio Replacement Program (ORP) boats, which carry nuclear-tipped ballistic missiles. Maintaining the nuclear deterrent for the worst case scenario takes top priority — but attack submarines are in high demand every day. The growing threat of nuclear-armed great powers increases the need for both kinds of boats. It’s a painful tradeoff the Navy would rather not make.

Now new Navy studies suggest the shipyards can keep building two Virginias a year, the current rate, even as they start building the first “boomer” in 2021. As Ohio Replacement production ramps up after 2021, however, keeping up two Virginias a year will become harder.


The Navy will present an updated Ohio Replacement Program cost estimate to the Defense Department later this summer and seek approval to move into detailed design and engineering work, the Program Executive Officer for Submarines said today.

The new ballistic missile submarine program will request a Milestone B decision from the Pentagon’s acquisition chief and the Defense Acquisition Board, and “coincident with that, we’re also producing a new cost estimate,” Rear Adm. Michael Jabaley said at an event co-hosted by the Center for Strategic and International Studies and the U.S. Naval Institute. He said the Navy is still working through this component cost position, of the lifecycle cost estimate, and is awaiting final approval of that dollar figure before presenting to the DAB.

A 2014 cost estimate put the program’s average follow-ship cost — ships two through 12, not including the typically most-expensive lead ship – at $5.2 billion, squarely in between the mandatory threshold of $5.6 billion and the target objective of $4.9 billion. Jabaley added that the 2014 cost estimate put the non-recurring costs – engineering work and building facilities to produce the subs – at $17.4 billion. Updated figures will be publicly released after the DAB approves the Milestone B decision, he said.

Jabaley said he views it as his responsibility to not only control costs for ORP but to actively seek ways to reduce cost.

China may Have a new Modified Balllistic Missile Submarine Class (or subclass)


After the recent revelation that China has a new variant of its Shang-class (Type 093) nuclear-powered attack submarine (SSN), new images suggest there is at least one Jin-class (Type 094) nuclear-powered ballistic missile submarine (SSBN) with similar modifications, called the Type 094A by some Chinese sources.

Russian Navy Upgrading Akula Class Attack Subs to use Kalibr (Sizzler) Antiship missiles

The upgrade of Russia's Project 971 Bars ('Akula')-class nuclear-powered attack submarines will arm them with Kalibr 3M-54 (SS-N-27A 'Sizzler') anti-ship missiles, Viktor Kochemazov, chief of the Russian Navy Training Department, told the RSN radio channel on 21 March. "Now, the upgrade of the Project 971 submarines provides for equipping them with the Kalibr system," he said.

The weapon "proved itself" during trials, according to Kochemazov. "Its use by the Rostov-on-Don diesel-electric submarine showed that the system is facing bright vistas in terms of further development," he said.

US Navy Planning Network of Robo Subs, Drones to Work with Future Attack Subs


Submarines today, and even more so in the future, will not only deliver weapons but will also carry a family of unmanned underwater and aerial vehicles to help extend their area of influence. Richard said the Navy has bought about 150 3-inch unmanned aerial vehicles (UAVs) and about a dozen 21-inch UAVs that are fully integrated with the submarine and send information back. The submarine community also has 16 21-inch Littoral Battlespace Sensing Autonomous Underwater Vehicles coming into the fleet for additional intelligence-gathering underwater.

In the future, though, Richard said there will be more UUVs, but “they won’t always come by submarine, they may come by a number of mechanisms – you may launch them from a surface ship, they may be launched from the pier. It’s just a capability, a node in an undersea constellation that will include the seabed, fixed distributed systems. Not all UUVs are going to look like little submarines, there’s a bunch of different ways to put this effect in there.”

This idea plays into Richard’s view of the undersea domain – operations shouldn’t be platform-centric but rather domain-centric. In a graphic of future underwater operations, Richard said “the submarine’s not in the middle of the picture. That’s intentional to show that it is just part of a larger system that we’re putting out there.”

India's Submarine Launched Ballistic Missile Test was a Success

Even as the Defence Research and Development Organisation (DRDO) has not yet made public its recent test of nuclear capable submarine launched ballistic missile (SLBM) K-4, the elite agency, known for developing some best weapons with minimum failures, has validated a few new technologies pushing the country one step ahead in indigenous technology.

A source on Tuesday told ‘The Express’ that the mission conducted secretly on March 7 from a submerged pontoon (replica of a submarine) in the Bay of Bengal off the Visakhapatnam coast was a ‘roaring’ success. Some critical parameters set by the mission team were successfully met during the test.

Future US Navy Attack Subs Will be Radically Different

The Navy won’t begin buying its next-generation attack submarine until 2034, but researchers are already hard at work on two key components of the SSN(X) program: an electric drive system for quieter operations, and the ability to control multiple unmanned underwater vehicles at once for extended influence.

These attack boats will operate through the end of the 21st century and perhaps into the 22nd century – and Program Executive Officer for Submarines Rear Adm. Michael Jabaley believes there will still be a place for submarines in naval operations as long as the boats can keep up with changes in the operating environment.

“There’s been a lot of discussion about the future of submarines and the future of stealth and the future of anti-submarine warfare – and we take all of that into account and still firmly believe there’s a significant role for the submarine in the United States Navy well into the heart of this century and beyond,” Jabaley told USNI News in a March 3 interview.

“Now, that said, there are a lot of things that are happening that require some fundamental changes to what we consider an attack submarine to be. And some of it we’re already doing” as the office works through the design of the upcoming Ohio Replacement Program ballistic missile submarine.

US Navy to Release RFP for Ohio Replacement Program

The Navy will soon release the request for proposals (RFP) for the design of the Ohio Replacement Program ballistic missile submarine, after the Defense Department approved the RFP release.

After finalizing a capability development document, specifications and a process to limit requirements changes in late October, the Navy went to the Defense Acquisition Board on Dec. 21 for authorization to proceed with the RFP.

“On Dec 21, the Navy sought Defense Acquisition Executive authorization to proceed with release of the Integrated Product and Process Development Request for Proposal for the Ohio Replacement program,” DoD spokeswoman Maureen Schumann told USNI News on Tuesday.
“At the DAB, [Pentagon acquisition chief Frank] Kendall reviewed the status of technology development, program schedule, the execution of the current contract and the Ohio Replacement acquisition strategy, and approved the release of the Development RFP.”

Russia Lays Keel for 7th Borey Class Nuclear Ballistic Missile Submarine

United Shipbuilding Corporation's Sevmash shipyard laid on 18 December the keel for the nuclear-powered ballistic missile submarine Emperor Alexander III : the Russian Navy's fourth modernised Dolgoruky (Borey-A)-class SSBN and the seventh boat in the Project 955/955A Borey class overall.

The newest Borey-A SSBN will deploy to the Pacific Fleet, according to Deputy Commander-in-Chief of the Russian Navy Vice Admiral Viktor Bursuk.

Three Dolgoruky (Project 955) submarines are already in service, and three Borey-A boats are in build at Sevmash. The navy plans to complete a total of eight Dolgoruky SSBNs by 2020.

Russian Project 09851 Nuclear Submarine Khabarovsk Potentially Indentified to Carry Doomsday Nuclear Torpedo/UUV Status-6/Kanyon


The pictures need permission of the original author to publish, so I did a teaser screenshot so you can be tempted to go look. 
Russia’s plan to create a giant nuclear torpedo capable of wiping out a costal city could be farther along than just graphics on a briefing slide and gives purpose to a mysterious nuclear submarine, currently under construction.

Last month Kremlin leaked its plan to develop a new the Status-6 (or Kanyon) strategic weapon under the guise of a state controlled television feed accidentally catching a glimpse of the program overview.
