A NEW FLEET OF HUNTER-KILLER SUBMARINES: THE ASTUTE CLASS
Each of the new submarines will cost around £1bn to make.
They have space for 38 weapons to stowed - including Spearfish heavy torpedoes and Tomahawk cruise missiles.
Each will measure 97m (318 ft) in length and weigh 7,400 tonnes.
Almost 40,000 acoustic tiles are placed on the Astute class submarines to mask their noise as they move through water, and make the ships virtually undetectable by enemies.
The Astute Class is being built by BAE Systems and were ordered 15 years ago.
Similarly to the Vanguard class, the ships have space for each member of the crew to have their own bunk.
The ships are fitted with a dry-deck so special forces can deploy while they are submerged.
They can circumnavigate the world without ever surfacing.
Each will have a sonar system so powerful it can detect ships leaving harbour in New York City from a listening point below the waters of the English Channel, 3,000 nautical miles away.
HMS Ambush is the second of the Astute class submarines to be launched but defects have been identified.
Second boat of this class HMS Ambush has yet to launch after 57 operational defects were found.

This chart shows every model of military submarine in service around the world
by Jeremy Bender
May 6, 2015,
Submarines give navies around the world a huge strategic and tactical advantage.
Ballistic-missile submarines can serve as nuclear deterrents if a country's land-based launch systems have been destroyed. Meanwhile, nuclear-powered attack submarines can effectively hunt enemy subs and can sink enemy naval targets. During war games in March, a French Rubis-class sub even "sunk" a US aircraft carrier.
Smaller non-nuclear attack submarines, though incapable of operating underwater for as long as nuclear vessels, can be even more difficult to track than their nuclear-fueled counterparts. These subs can also be used for naval and anti-submarine warfare in shallower waters.
The following graphic from Naval Graphics shows every model of submarine in service around the world as of 2015:
You can see the graphic in closer detail here»
http://i.imgur.com/EbRPD3f.jpg
On average, the largest submarines in service are ballistic missile-armed. As these submarines are intended for nuclear strikes or long-range missile attacks, few nations have the need or desire to operate them. Today, only Russia, China, France, the US, and the UK have ballistic-missile submarines in their navies.
Likewise, the same five countries are the only nations to possess nuclear attack submarines, though the Indian Navy is operating a loaned Russian sub. These subs are generally slightly smaller than ballistic-missile submarines and are capable of staying submerged for months at a time.
In general, the greatest number of submarines owned and operated around the world are of the non-nuclear variety. These submarines are powered via air-independent propulsion, diesel-electric engines, or a combination of both.
Though these non-nuclear submarines are small and cannot remain submerged as long as nuclear subs, newer models can potentially run quieter than the nuclear-powered models, allowing them to evade detection and attack surface ships or other submarines.

Was just wondering. UK and US both operate same SLBMs and both have a daunting task of replacing their SSBN fleets.
Won't it be economical and easier for both US and UK to join hands in building a common platform ?
Or there is an international law stopping it ?

Might depend on time table, plus the strategic consideration of wnating to maintain the capability to design and build nuclear submarines domestically. (technology base)
A total force of seven Astute class fleet submarines is planned.
As of April 2016, the first three boats are in commission (resp. 2010, 2013 and 2016) and in service, while boats four to six are in various stages of construction. Boat number seven was confirmed in the October 2010 Strategic Defence and Security Review and long-lead items have been ordered. The seventh boat should enter service 2024.
Currently there are still 4 Vanguard in service. A successor to the Vanguard class of submarines is in its early stages, with 'Main Gate' decisions to be made in 2016. The programme will seek to replace the current Vanguard-class ballistic missile submarines starting sometime during the mid-to-late 2020s, i.e. when the oldest Astute is about 20 years old.

During 800 days USS Florida submarine was one of the most versatile and clandestine platforms for US Navy
18 May 2020

During 800 days of deployment, the Ohio-class guided-missile submarine USS Florida (SSGN 78) was one of the most versatile and clandestine platforms in the fleet of U.S. Navy. Guided-missile submarines are capable of carrying up to 154 Tomahawk land-attack cruise missiles and host up to 66 Special Operation Forces.
The USS Florida (SSGN-728) Ohio-class cruise missile submarine, is the sixth ship of the United States Navy to be named for the 27th state. She was commissioned with the hull designation of SSBN-728 in June 1983. The USS Florida entered Norfolk Naval Shipyard in July 2003 to undergo a refueling and conversion from an SSBN (Ballistic Missile Submarine) to an SSGN (Cruise Missile Submarine).
Florida is one of just four guided-missile submarines in the U.S. Navy's fleet and comprises half of the guided-missile submarine force in Kings Bay, home to all East Coast Ohio-class submarines to include five ballistic-missile and two guided-missile submarines. It has completed more than 50 patrols before its conversion to a guided-missile submarine. SSGNs are equipped with superior communications capabilities and have the ability to carry up to 154 Tomahawk land-attack cruise missiles. The platform can also be configured to host up to 66 Special Operation Forces.
While forward deployed, the ship sailed more than 98,000 nautical miles, which is the equivalent to nearly four times around the world, and pinned 202 new submariners with their submarine warfare, or “Dolphins.”
As an Ohio-class submarine, Florida has two crews; blue and gold. These crews of roughly 160 Sailors alternate manning the submarine and typically deploy with the ship for three months before swapping. The blue crew brought the submarine back to its homeport. The crew that isn’t deployed, trains at Trident Training Facility Kings Bay, conducting a rigorous training program including simulated missions and scenarios they could encounter while at sea. This constant training regimen helps ensure the crew is always tactically and operationally ready.
On 19 March 2011, in conjunction with other U.S. Navy and Royal Navy warships and submarines, Florida fired scores of Tomahawk missiles at Libyan air defense targets as part of Operation Odyssey Dawn. Operation Odyssey Dawn was the U.S. code name for the American role in the international military operation in Libya to enforce United Nations Security Council Resolution 1973 during the initial period of 19–31 March 2011 The Tomahawk missile strikes allowed British, French, and allied warplanes to begin enforcing a no-fly zone over Libya, preventing Muammar Gaddafi from using his air force to attack rebels in his country. This was the first combat action for the Florida or any other Ohio-class submarine. During Operation Odyssey Dawn, Florida launched 93 Tomahawk missiles, with 90 effective, out of her total magazine of about 160 missiles.
The Tomahawk is a long-range Land Attack Missile (TLAM), all-weather, jet-powered, subsonic cruise missile that is primarily used by the United States Navy and Royal Navy in ships and submarine-based land-attack operations. At least six variants and multiple upgraded versions have been introduced since then, including air-, sub-, and ground-launched variants and conventional and nuclear-armed ones. As of 2019, only non-nuclear, sea-launched variants assembled by Raytheon are currently in service. It has an operational range of 2,500 km.

Trials continue for Russian Navy Project 955A Borei-A class nuclear-powered submarine Knyaz Vladimir
May 2020
Russian Navy Borei-A Knyaz Vladimir submarine during sea trials.
Russian Navy Search-and-rescue forces of the Northern Fleet and the White Sea naval base are supporting the state trials of the Project 955A Borei-A class lead nuclear-powered submarine Knyaz Vladimir, the Russia Defense Ministry’s press office said, on May 15, 2020.
The submarine has gone to the White Sea from Severodvinsk in north Russia, the Russian press office added. The current stage of the trials in the White Sea is being supported by the Zvyozdochka rescue tugboat and the Mikhail Rudnitsky rescue vessel.
“The sea trials will last several days and take place above water and then underwater. During the trials, work to remove faults detected earlier will be checked and then it will be decided when the submarine can join the Northern Fleet,” the press office said.
The major part of the trials, including missile and underwater firing, was completed by the Knyaz Vladimir in late 2019. At that time, the submarine was supported by forces of the Northern Fleet’s White Sea naval base.
The Borei class, Russian designation Project 955 Borei and Project 955A Borei-A are series of nuclear-powered ballistic missile submarines being constructed by Sevmash for the Russian Navy. The Borei submarine is approximately 170 meters (560 ft) long, 13 meters (43 ft) in diameter, and have a maximum submerged speed of at least 46 kilometers per hour (25 kn; 29 mph).
Borei-A submarine is equipped with improved communication and detection systems, improved acoustic signature and has major structural changes such as addition of all moving rudders and vertical endplates to the hydroplanes for higher maneuverability, and a different sail geometry. This submarine is also equipped with hydraulic jets and improved screws that allows them to sail at nearly 30 knots while submerged with minimal noise. According to Russian report, the Borei-A is able to carry 20 Bulava SLBM and is armed with 16 SLBMs with 6-10 nuclear warheads atop each, just like the Borei submarines.
