Iran draws up designs for nuclear powered submarine

[The SC]

Iran said it was drawing up designs for its first nuclear powered submarine yesterday, putting it in position to become the first nation not nuclear armed to put the technology to front line military use.

It maintained yesterday that its programme would remain peaceful and even if it introduced nuclear-powered systems into its submarines. "Initial steps to design and build nuclear submarine propulsion systems have begun," Admiral Abbas Zamini, the technical deputy navy chief said. "All countries have the right to use peaceful nuclear technology, including for the propulsion system of its vessels," he said. The navy "needs the (nuclear-powered) propulsion system to succeed in realising very long-distance operations."

"Our aim isn't aggression but if someone attacks us we will defend ourselves," he added.

Iran announced it would domestically manufacture submarines in 2008. Its navy has 23 submarines, including three Russian Kilo-class attack vessels, as well as 12 midget submarines.

Tehran is in the “initial phase” of designing nuclear-powered submarines, says a senior Iranian Navy commander.

*"Initial steps to design and build nuclear submarine propulsion systems have begun," Admiral Abbas Zamini, the technical deputy Navy Chief, told semi-official Fars news agency on Tuesday.

A nuclear-powered submarine would allow “very long-distance operations."

"All countries have the right to use peaceful nuclear technology, including for the propulsion system of its vessels," added the admiral.

Only a handful of nations can boast their own technology to make nuclear-powered submarines. These include the US, the UK, Russia, France and China. India is also reportedly building one.

good. Iran must be a nuclear power to counter Israel , US.

It is always good to try and have the best in any science and technology, and make new discoveries.

tell that to the torch bearers of Islam..the KSA

tell that to the torch bearers of Islam..the KSA

they should too but not just because Iran gets.

 

[ihealugo]

a different between iran and KSA : iran build its own equipment, but KSA just buy them so in a war if we lose something we can rebuild it later , because we have the technology but if KSA lose it , he need to pay again alot of money for the lost one ...

To make very advanced weapon systems it takes a lot of national effort and a strong political will like Iran, on top of it it needs heavy industrialisation.
So while Iran is in an advanced stage (not the most advanced, otherwise Iran could manufacture airplane engines and just copy the F-14 tomcat integrally and add new features to it), KSA is just in the beginning of TOT and seeking some more, so it has no other choice than to by weapons, and at least it is buying some of the most advanced, if it can get its hands on their TOT and accelerate its heavy industries, it will be self reliant in a generation time.
And in time the two nations will be close to each other, with enough weapons to defend the whole region.

Good job Iran, keep making progress with Technology.

It took the US merely 3-4 years 1951-1954 to field its first nuclear submarine The Nautilus

Displacement: 2,980 tons light, 3,520 tons full, 540 tons dead

In July 1951 the United States Congress authorized the construction of a nuclear-powered submarine for the U.S. Navy, which was planned and personally supervised by Admiral Hyman G. Rickover, known as the "Father of the Nuclear Navy."[3] On 12 December 1951 the U.S. Department of the Navy announced that the submarine would be called Nautilus—the fourth U.S. Navy vessel officially so named[4]—and would carry the hull number SSN-571.
Nautilus core prototype at the S1W facility in Idaho.

Nautilus's keel was laid at General Dynamics' Electric Boat Division in Groton, Connecticut by Harry S. Truman, President of the United States, on 14 June 1952[5], and the ship was designed by John Burnham. She was christened on 21 January 1954 and launched into the Thames River, sponsored by Mamie Eisenhower, the wife of Truman's successor Dwight D. Eisenhower. Nautilus was commissioned on 30 September 1954, under the command of Commander Eugene P. Wilkinson, USN.

Nautilus was powered by the S2W naval reactor, a pressurized water reactor produced for the US Navy by Westinghouse Electric Corporation. Argonne National Laboratory, together with Westinghouse, developed the basic reactor plant design used in the USS Nautilus after being given the assignment on Dec. 31, 1947 to design a nuclear power plant for a submarine.[6] Nuclear power had the crucial advantage in submarine propulsion because it is a zero-emission process that consumes no air. The physics-critical experiments supporting this design were performed at Argonne. This design is the basis for nearly all of the US nuclear-powered submarine and surface combat ships, and was adapted by other countries for naval nuclear propulsion. The first actual prototype (for the Nautilus) was constructed and tested by Argonne at the S1W facility in Idaho.

Following her commissioning, Nautilus remained dockside for further construction and testing. At 11 a.m. on 17 January 1955 she put to sea for the first time and signaled her historic message: "Underway on nuclear power."[7] On 10 May, she headed south for shakedown. Submerged throughout, she traveled 2,100 km (1,100 nautical miles) from New London to San Juan, Puerto Rico and covered 2,223 km (1,200 nm) in less than ninety hours. At the time this was the longest submerged cruise by a submarine and at the highest sustained speed (for at least one hour) ever recorded.

From 1955 to 1957, Nautilus continued to be used to investigate the effects of increased submerged speeds and endurance. The improvements rendered the progress made in anti-submarine warfare during the Second World War virtually obsolete. Radar and anti-submarine aircraft, which had proved crucial in defeating submarines during the War, proved ineffective against a vessel able to quickly move out of an area, change depth quickly and stay submerged for very long periods.

On 4 February 1957, Nautilus logged her 60,000th nautical mile (111,120 km), matching the endurance of her namesake, the fictional Nautilus described in Jules Verne's novel Twenty Thousand Leagues Under The Sea.[citation needed] In May, she departed for the Pacific Coast to participate in coastal exercises and the fleet exercise, operation "Home Run," which acquainted units of the Pacific Fleet with the capabilities of nuclear submarines.

Nautilus returned to New London, Connecticut, on 21 July and departed again on 19 August for her first voyage of 2,226 km (1,202 nmi) under polar pack ice. Thereafter, she headed for the Eastern Atlantic to participate in NATO exercises and conduct a tour of various British and French ports where she was inspected by defense personnel of those countries. She arrived back at New London on 28 October, underwent upkeep, and then conducted coastal operations until the spring.

In response to the nuclear ICBM threat posed by Sputnik, President Eisenhower ordered the US Navy to attempt a submarine transit of the North Pole to gain credibility for the soon-to-come SLBM weapons system.[8] On 25 April 1958, Nautilus was underway again for the West Coast, now commanded by Commander William R. Anderson, USN. Stopping at San Diego, San Francisco, and Seattle, she began her history-making polar transit, operation "Sunshine", as she departed the latter port 9 June. On 19 June she entered the Chukchi Sea, but was turned back by deep draft ice in those shallow waters. On 28 June she arrived at Pearl Harbor to await better ice conditions. By 23 July her wait was over, and she set a course northward. She submerged in the Barrow Sea Valley on 1 August and on 3 August, at 2315 (EDST) she became the first watercraft to reach the geographic North Pole.[9] The ability to navigate at extreme latitudes and without surfacing was enabled by the technology of the North American Aviation N6A-1 Inertial Navigation System, a naval modification of the N6A used in the Navaho cruise missile. (The N6A-1 had been installed on the Nautilus and the Skate, after initial sea trials on the USS Compass Island in 1957.)[10] From the North Pole, she continued on and after 96 hours and 1,590 nmi (2,940 km) under the ice, she surfaced northeast of Greenland, having completed the first successful submerged voyage around the North Pole. The technical details of this mission were planned by scientists from the Naval Electronics Laboratory including Dr. Waldo Lyon who accompanied Nautilus as chief scientist and ice pilot.

Iran has the experience now, so I won't be surprised if we see a nuclear powered Iranian sub by the end of 2013.
