Met Israel Newest, Most Expensive Weapon: INS Submarine Tanin*
In a commemoration aboard Israel’s 4th and newest submarine, the INS Tanin (“crocodile,” or “alligator”), the IDF on Sunday held a wreath-laying ceremony at the site where 69 soldiers of INS Dakar went down with the ship, in the Mediterranean Sea some 270 miles off the Israeli coast in 1968, the Israeli army said.
“We will guard, protect, and act in any enemy coast, and fight bravely for the navy and the state of Israel,” Adm. Ram Rothberg, said at the event, The Jerusalem Post noted.
Referring to the prowess of the new Dolphin-class craft, IDF Chief of Staff Lt.-Gen. Benny Gantz said that, “Without a doubt, this power, operationally and strategically, is very important for Israel, the IDF and the navy.”
The INS Tanin is the most expensive weapon currently in IDF service, at a cost of over $513 million dollars, and is considered one of the most sophisticated submarines in the world.
“More than four decades passed since INS Dakar’s last voyage… Although the threats have changed, and today you have the most modern equipment, the most advanced technologies, and the most quality means, the mission remains the same mission that the INS Dakar personnel were sent on, and the responsibility is the same. To protect the Israeli coast, sea waters, and working with all of the IDF’s branches to achieve the relevant goals,” Gantz said.
In addition to the IDF’s top brass, three survivors of the Dakar were aboard: Abraham Szabo, Israel Rosen and Abraham Carmel.
The three, who were supposed to have boarded the submarine, at the last minute received orders to remain dockside and wait a few days before another ship was scheduled to arrive in Israel, according to Israel’s NRG News.
According to the Defense Industry Daily, the diesel-electric attack submarine will be outfitted with its Israeli systems after arrival at a specially-made, secretive dock in Haifa.
The sub is reportedly designed for a crew of 35 and can support 10 passengers. It is said to have a maximum speed of 20 knots, and a maximum range of 2,700 miles (4,500 km).
The craft can fire torpedoes and missiles, perform underwater surveillance, and launch combat swimmers out of wet and dry compartments.
According to Janes, the Dolphin-class subs are reportedly nuclear-armed, possibly with Israel’s Popeye Tubo cruise missile.
The official festive welcoming ceremony is set for Tuesday in Haifa.
The next craft in the fleet, the INS Rahav is scheduled to arrive in Israel during 2015, with a sixth projected to arrive in 2019.

U.S. Submarines: Run Silent, Run Deep... On Diesel Engines?*
"Underway on nuclear power", radioed the skipper of USS Nautilus in 1955, after taking history's first nuclear-powered attack submarine to sea for the first time. Nautilus's maiden cruise left an indelible imprint on the navy. Her success, cheered on by the likes of Admiral Hyman Rickover, the godfather of naval nuclear propulsion, helped encode the supremacy of atomic power in the submarine force's cultural DNA.
Things were never the same after that. America built its last diesel-electric sub, once the state of the art, not long after Nautilus took to the sea. Not since 1990 has the U.S. Navy operated conventionally powered boats. It's been longer than that since they were frontline fighting ships. For a quarter-century, then, it's been all nukes, all the time. No U.S. shipbuilder even constructs diesel boats nowadays.
That was then. Now may be the time to break up the nuclear monopoly. To wit, imagine permanently forward-deploying a squadron of diesel attack boats, or SSKs, to likely hotspots. Such a force would expand America's silent service, reversing the ongoing slide in numbers of hulls. It would do so at reasonable cost in this age of budgetary stress. A standing East Asia squadron would be close to the action. Likely based in Japan and Guam, it would amplify the U.S.-Japanese fleet's prowess vis-á-vis China's navy and merchant marine. It would empower Washington and Tokyo to deny China access to offshore waters without committing the whole fleet of U.S. nuclear-powered boats to the endeavor. And in the process it would open up new vistas for building and reinforcing alliances.
Greater numbers, middling cost, a heavier punch in battle. That's a major contribution from such humble craft. U.S. submariners' diesel-propelled past could be, and should be, part of their future.
There's nothing new or especially radical about conventional U.S. subs' prowling the Western Pacific deep. They did so to devastating effect during World War II. For instance, the Philippine Islands was home to the largest concentration of U.S. submarines in the Pacific on the eve of hostilities. U.S. commanders squandered a golden opportunity to run wild against transports carrying Japanese troops to invade the Philippines. But their missed opportunity doesn't detract from subs' potential to confound opponents amid Asia's intricate nautical terrain. It's an exception that proves the rule.
And indeed, American submarines vindicated their potential in ensuing years. U.S. Pacific Fleet boats were among the first vessels to return to Asia following the Japanese raid on Pearl Harbor. Ordered to sea while the battle line was still ablaze at Ford Island, they helped dismember an island empire. Empires like Japan's depend on ships to ferry all manner of warmaking materiel—raw materials, foodstuffs, finished goods—hither and yon. Take away seaborne movement and you cut the lineaments binding the imperial enterprise together.
The submarine campaign grew more and more effective as the U.S. offensives undulated across the Central and South Pacific. U.S. Navy, Marine and Army amphibious forces wrested outer islands from Japan, letting the navy position, maintenance and logistics outposts closer to the foe. Submarine tenders—floating repair and supply depots for all intents and purposes—staged support operations westward of Hawaii. As the transpacific campaigns progressed, boats wasted less time transiting to and from assigned hunting grounds. They spent more time strewing the seafloor with enemy merchantmen and men-of-war.
Forward bases, then, offset the tyranny of distance—allowing the submarine force to mount a stifling presence in Asian waters. Wartime prime minister General Hideki Tōjō catalogued submarine warfare among three critical determinants of Japan's defeat—high praise from someone in a position to know.
And afterward? Ravaged by undersea combat during World War II, Japan built an impressive submarine force of its own to help prosecute the Cold War. Japan Maritime Self-Defense Force (JMSDF) diesel boats turned geography to advantage, lurking in and around the straits that pierce Asia's offshore island chains. Crews monitored and encumbered east-west movement between the China seas and the Western Pacific. Soviet skippers often balked at attempting the passage. The JMSDF, in short, forged itself into a lethal weapon for a cold war beneath the waves.

Aquest tema, que ha estat gairebé tabú per l'obsessió quasi religiosa per la "all nuclear fleet", es suma a una altra " heretgia" com és l'aquisició d'un tipus de submarí dissenyat a l'estranger: AL JAPÓ! Esperem que facin cas a aquestes tesis, doncs l'equilibri de forces al Pacífic en depèn directament.

Navy to Conduct Strike Missile Demonstration Aboard LCS 4*
WASHINGTON — The Navy is scheduled to conduct a live-fire demonstration of a Kongsberg-built Naval Strike Missile (NSM) aboard the littoral combat ship USS Coronado (LCS 4) while underway in the Pacific Ocean Sept. 24, a Naval Sea Systems Command spokesman announced in a Sept. 18 release.
The Kongsberg NSM is a long-range precision-strike missile designed to be launched from a variety of ships against a variety of targets. This demonstration is intended to test the capabilities of the Norwegian-made missile from a sea-based platform against a Mobile Ship Target (MST) and provide insights into the weapon’s stated capabilities of increased range and lethality. The Navy does not currently have any acquisition or integration requirements for the NSM aboard any of its ships.
“We saw what the missile could do from a Norwegian ship during RIMPAC [Rim of the Pacific exercise], and now have the opportunity to see it perform from one of our ships,” said RDML Jon Hill, program executive officer, Integrated Warfare Systems. “We’re excited to see what potential the missile has as a possible future warfighting tool for the U.S. Navy.”
The planned live firing demonstration of the NSM will take place under the Foreign Comparative Testing (FCT) program and will act as a demonstration of the ship’s potential to execute an increased anti-surface warfare role. The FCT program is designed to test items and technologies of foreign allies that have a high Technology Readiness Level in order to satisfy valid defense requirements quickly and economically.
The NSM currently is used on Norwegian Nansen Class frigates and Skjold-class missile torpedo boats, and in the Polish Coastal Missile Division. Kongsberg has previously contracted with the U.S. Navy to supply simulation training tools for Navigation, Seamanship, and Shiphandling Training (NSST) programs.
Program Executive Office Integrated Warfare Systems, together with Program Executive Office Littoral Combat Ships, will coordinate the demonstration. In the event of inclement weather or an unfavorable sea state, the demonstration will be conducted Sept. 25.
