Top nuclear submarines of the World


How's the Josh Warriors?


Hello Buddies, I hope you are applying every inch of hard work and effort to earn the prestigious uniform of the Indian Armed Forces. 

Nuclear Submarines are entering a New Era as the India’s INS Arihant enters sea trials and the United Kingdom orders new reactors. In this appreciable blog, I am going to profile the world’s leading nuclear submarines.


Following are the top nuclear submrines of the world


The INS Arihant

  • INS Arihant is the India’s historic first nuclear poweredindigenously developed submarine, launched at the Indian Navy’s dockyard in Visakhapatnam (Kerala).

  • The INS Arihant was jointly developed by the India's Bhabha Atomic Research Centre (BARC) & Defence Research and Development Organisation (DRDO), with the assistance from Russian Designers.

  • 05 further submarines are planned, with the hulls for the second and third submarines alleged by the Indian Express to have already been constructed. Prior to the vessel’s commissioning, INS Arihant will undergo extensive sea trials for at least two years.


The Astute Class

  • The service life of the UK Royal Navy’s Astute Class Submarines was designed to replace the Swiftsure Class Submarines and procedure was began with the commissioning of HMS Astute in August, 2010.

  • Of the 07 Astute Class Submarines ordered, four have been completed with three in various stages of construction.

  • HMS Ambush was commissioned by 2013, followed by HMS Artful and HMS Audacious in 2018.

  • HMS Anson and HMS Agamemnon are expected to enter into service in 2020 and 2022 respectively. Although the seventh submarine, HMS Ajax, has been confirmed to be commissioned by 2030.


The Vanguard Class

  • Vanguard Class Submarines became all important for the UK Royal Navyfollowing the decommissioning of RAF WE.177 free-fall nuclear bombs, as the vessels became the only remaining platform for the UK’s nuclear weapons.

  • The first of the Vanguard Class submarines, HMS Vanguard was commissioned in 1993, followed by HMS Victorious in 1995, HMS Vigilant in 1996 and HMS Vengeance in 1999.

  • The vessels have undergone a Long Overhaul Period and Refuel Refit conducted by Babcock, with HMS Vengeance set to become the last Astute Class submarine to enter the programme following HMS Vigilant’s completion in 2012.


The Ohio Class

  • The Ohio Class was commissioned between 1981 and 1997, the US Navy possesses 18 Ohio Class submarines split between the Nation’s Pacific and Atlantic Fleets.

  • 04 of the 18 submarines have since become conventionally armed, nuclear-powered submarines following the Strategic Arms Reduction Treaty.

  • The treaty capped the number of strategic missile submarines at 14, after which Electric Boat contracted to complete the conversion of USS OhioUSS MichiganUSS Florida and USS Georgia.

  • As part of the conversion, the submarines have been refitted with up to 154 Tomahawk TLAM or Tactical Tomahawk Missiles and will be capable of conducting special operations missions.


The Virginia Class

  • The Virginia Class submarines is designed to be a less expensive alternative to the Cold War-Era Seawolf Class attack submarines and have been in service with the US Navy since 2004. 

  • Of the 30 that are planned to enter into service, nine are currently active with a further five under construction.

  • The US Navy opted to install a number of commercial-off-the-shelf components aboard the Virginia Class submarines which, coupled with improvements in manufacturing technologies, resulted in savings of approximately $1.8 billion/submarine over the expensive Seawolf Class Vessels.

  • Further cost savings have been found by constructing the vessels in four sections rather than 10, saving approximately $300 million/vessel

  • The overall cost per submarine has subsequently fallen to $2billion/boat.


The Barracuda Class

  • The France’s fleet of six Barracuda Class submarines has been designed to replace the nation’s four Rubis Submarines and two Amethyst Class Submarines, with the fleet considered a key element of the Force Oceanique Strategique Navy Command.

  • The submarine was Constructed at a unit cost of approximately €1.45 billion, of the six planned vessels, two are currently under construction.

  • The first submarine, named Suffren,was delivered in 2016 and commissioned in 2017, with the remaining vessels to be delivered every two years through to 2026. The entire cost of the Barracuda programme has been estimated at €8.7 billion.


The Borei Class

  • The Russia’s first new-generation Borei Class submarine, the Yury Dolgoruky, is the first submarine launched by Russia since the fall of the Soviet Union and will be deployed in the Pacific Fleet of the Russian Navy.

  • The fourth-generation vessels have been in development since 1996 and are intended to replace the Delta III and Typhoon Class Submarines.

  • To date, just two Borei-Class submarines have been completed, with the Alexander Nevsky joining the Yury Dolgoruky in sea trials.

  • Two further submarines, the Vladimir Monomakh and the Knyaz Vladimir, are currently under construction, with a further six vessels planned to be commissioned for Russia.
