[News analysis] N. Korea threatens US “extended deterrence” with missile tests The Hankyoreh
New Delhi: Arighat, the second of the indigenous Arihant class nuclear-powered ballistic missile carrying submarine (SSBN), is in the final stages of sea trials and will be commissioned early next year, ThePrint has learnt.
Sources in the defence and security establishment said the submarine has performed well during the sea trials so far, and added that the commissioning of the vessel was delayed due to the coronavirus pandemic.
“It should be done (commissioned) early next year,” a source said.
The Arighat was quietly launched in November 2017 by the then Defence Minister Nirmala Sitharaman.
With Arighat in, India will be operating two SSBNs that are equipped with the 750 KM range K-15 submarine-launched ballistic missile, meant for punitive retaliatory strikes in case of a nuclear attack.
Both INS Arihant, which is on operational deployment, and the Arighat have the capacity to carry four missiles each.

India’s submarine plan
While the original plan was to have four Arihant class submarines, it was changed by the UPA government, sources in the know said.
Now, the two Arihant class submarines will have a displacement of 6,000 tonnes while two other SSBNs will be of a larger size (7,000 tonnes displacement).
A key differentiating factor will be that the two larger vessels under construction — S4 and S4* at the Ship Building Centre in Visakhapatnam — will have eight missile tubes instead of four.
India currently also operates a nuclear-powered attack submarine (SSN) INS Chakra II, which is under lease from Russia.
It was in March last year that India and Russia signed a US$3 billion deal for the lease of a third SSN — Chakra III — that is likely to be in Indian waters by 2025 at the earliest.
Russian submarines are being leased to train crews for India’s own fleet of SSBNs.
In 2015, the Narendra Modi government gave the green light to build six indigenous SSNs. About two years later, in 2017, then Navy chief Admiral Sunil Lanba had confirmed that work on the SSNs had started.

India’s nuclear triad
It was in November 2018 that India completed its nuclear triad when PM Modi announced to the world the completion of the first deterrence patrol by Arihant.
With that, India joined an elite group of countries that have the capability to launch a nuclear weapon from land, air and underwater. The only other countries capable of this are the US, Russia, China and France.
INS Arihant was commissioned in 2016 by then defence minister Manohar Parrikar, but a formal announcement came only two years later.

Why news media is in crisis & How you can fix it
India needs free, fair, non-hyphenated and questioning journalism even more as it faces multiple crises.
But the news media is in a crisis of its own. There have been brutal layoffs and pay-cuts. The best of journalism is shrinking, yielding to crude prime-time spectacle.
ThePrint has the finest young reporters, columnists and editors working for it. Sustaining journalism of this quality needs smart and thinking people like you to pay for it. Whether you live in India or overseas, you can do it here.

Another note: The Navy did not ask me to provide a link to their website (or do anything for that matter), but I’m going to provide a link because I want smart people to become submariners.

There are tons of interesting career opportunities out there that I never knew about:
The US Navy has several options such as engineer, pilot, submariner, logistics, accountant, medical doctor, and even Public Affairs specialist. I continue to be impressed by people that I meed who spent time in the Navy. I worked with various people during the course of filming this video and they were all top notch.

The US Builds A New Submarine The World Is Afraid Of
When you think of the most impressive assets in the U.S. Military arsenal; stealth bombers, destroyers, and tanks are probably what first come to mind. But now we might just radically shift your perspective. New attack submarines are being built for the U.S. Military, in particular, the Virginia-Class Block V Submarines which are not only powerful, but have nuclear attack capabilities…

World Most Feared Super Submarine in U.S, Navy – The Virginia Class attack submarine is the U.S. Navy’s newest undersea warfare platform and incorporates the latest in stealth, intelligence gathering and weapons systems technology. Attack submarines are designed to seek and destroy enemy submarines and surface ships; project power ashore with Tomahawk cruise missiles and Special Operation Forces; carry out Intelligence, Surveillance, and Reconnaissance (ISR) missions; support battle group operations; and engage in mine warfare.
The Virginia class wa not the first new design to come into service after the Cold War. The Seawolf class was originally intended to succeed the Los Angeles class, but production was canceled after only three submarines were produced. This restriction occurred due to budgeting restraints at the end of the Cold War, and the final submarine was manufactured in 1995. At a cost of $3 billion per unit, the Seawolf class was the most expensive SSN submarine. The Virginia class was put into production in full swing due to being smaller and carrying more manageable costs than the Seawolf.
The Navy is now building the next-generation attack submarine, the Virginia (SSN 774) class. The Virginia class has several innovations that significantly enhance its warfighting capabilities with an emphasis on littoral operations. Virginia class SSNs have a fly-by-wire ship control system that provides improved shallow-water ship handling. The class has special features to support special operation forces including a reconfigurable torpedo room which can accommodate a large number of special operation forces and all their equipment for prolonged deployments and future off-board payloads.
The class also has a large lock-in/lock-out chamber for divers. In Virginia-class SSNs, traditional periscopes have been supplanted by two photonics masts that host visible and infrared digital cameras atop telescoping arms. With the removal of the barrel periscopes, the ship’s control room has been moved down one deck and away from the hull’s curvature, affording it more room and an improved layout that provides the commanding officer with enhanced situational awareness. Additionally, through the extensive use of modular construction, open architecture, and commercial off-the-shelf components, the Virginia class is designed to remain state of the practice for its entire operational life through the rapid introduction of new systems and payloads.
As part of the Virginia-class’ third, or Block III, contract, the Navy redesigned approximately 20 percent of the ship to reduce their acquisition costs. Most of the changes are found in the bow where the traditional, air-backed sonar sphere has been replaced with a water-backed Large Aperture Bow (LAB) array which reduces acquisition and life-cycle costs while providing enhanced passive detection capabilities. The new bow also replaces the 12 individual Vertical Launch System (VLS) tubes with two 87-inch Virginia Payload Tubes (VPTs), each capable of launching six Tomahawk cruise missiles. The VPTs simplify construction, reduce acquisition costs, and provide for more payload flexibility than the smaller VLS tubes due to their added volume.

These US Navy Ohio class SSBN submarines have 24 Trident missiles with 8 MRV warheads per missile. These missiles have up to 7,000 miles range. It’s crazy to even think about attack and invade the US even for China or Russia. US Navy has 14 of these SSBN plus 4 converted SSGN with Tomahawk cruise missiles. These submarines are backbones of the US nuclear force which is the largest nuclear ballistic missile force in the world.
