There has been an active build-up of the ice-rated ships fleet by Russia in support of its operations in the Arctic in recent years. Russia is developing several icebreakers differing in power and displacement, with some of them intended for the Navy. The efforts are especially important owing to the country’s ramping up its operations in the Arctic.

The Krylov State Research Center set up the Arctic Engineering Center (AEC) in 2016, according to Krylov’s Director General Vladimir Nikitin. He said the new division was continuously in touch with both major energy companies and the Russian Defense Ministry. A whole range of federal programs is being pursued as part of this cooperation, including the development of icebreakers, support vessels and other marine hardware.

Admiralty Wharfs laid the keel of the Russian Navy-ordered Project 21180 lead ship, the Ilya Muromets icebreaker, in St. Petersburg in April 2015 and launched it in June 2016. The icebreaker is planned for commissioning in the fall of 2017 after it passes its tests. The Ilya Muromets has become the first icebreaker being built for the Navy over the past 45 years. In the fall of 2017, it will head for the Northern Fleet, which Arctic operations it will support further down the road. The ship is able to lead surface combatants and auxiliary vessels through the ice or tow them, if need be. It is tripled-hatted as seagoing tug, icebreaker and patrol ship.

According to the non-nuclear icebreaker’s requirements specification, it will be able to negotiate 80-centimeter-thick ice. Presumably, its endurance will stand at 60 days, cruising range at 12,000 nm, displacement at 6,000 tons, length at 84 m, beam at 20 m and draft at 7 m. The Ilya Muromets is Russia’s first icebreaker with Azipod thrusters hinged outside of the hull and able to traverse 360 deg. Its crew will be 32.

In July 2016, Rosatom Director General Sergei Kiriyenko said the job of its advanced Project 22220 icebreakers included leading naval convoys in the Arctic. The Project 22220 class is important to Russia’s defense and competitiveness as far as the Northern Sea Route transit is concerned. The Baltic Shipyard laid down the lead ship in the class, the Arktika, in November 2013. The cost of the class is estimated at 122 billion rubles ($2 billion). Technologies totally novel to nuclear warships have been used as part of its construction. Its variable-depth dual draft will allow leading convoys both on the high seas and in estuaries while its sophisticated nuclear reactor will necessitate port calls for intermediate recharging less than once every six months. Presumably, the icebreaker will be able to do without reactor reloading for about seven years.

The Iceberg Design Bureau plans to deliver three Project 22220 nuclear-powered icebreakers prior to 2020. In addition, it is designing other advanced icebreakers, Iceberg Director General/Chief Designer Alexander Ryzhkov told TASS in December 2015.

"The Baltic Shipyard is building Project 22220 nuclear icebreakers. Three are to be delivered to government-owned Atomflot prior to 2020. These are unique vessels equipped an advanced monoblock reactor, a sophisticated steam-turbine plant, an electric propulsion system and latest automatic mechanisms. The icebreaker varies her draft within the 8.5-10.5-m bracket, which enables her to operate both on the Northern Sea Route and in the estuaries of Siberian rivers," Ryzhkov says.

With the 10.5-m maximum draft, the class has an ice-breaking capability of 2.8-3 m and, thus, is fit for operations in the east of the Arctic all year round. The solutions embodied by the Project 22220 icebreakers makes them fit for replacing two icebreaker classes simultaneously - the seagoing Project 10521 Yamal and 50 Let Pobedy and the shallow-draft Project 10580 Taimyr and Vaigach. Rosatom may order two more Project 22220 versatile icebreakers from the United Shipbuilding Corporation (USC), according to the materials the Industry and Trade Ministry prepared for a session of the government’s Arctic board.

In recent years, there has been an active build-up of Russia’s ice-rated ships fleet designed for for operations in the Arctic. In particular, the Almaz Design Bureau has developed the unique Project 23550 patrol ship capable of executing in the icebreaker, tug and patrol ship roles.

The Admiralty Wharfs Shipyard in St. Petersburg has laid the keel of the lead ship of the Project 23550 class, the Ivan Papanin ice-class patrol corvette intended for the Russian Navy.

"Today is a special day for the Navy and military shipbuilders. Today is the birthday of the ship that is designed to guard our Arctic expanses. The ice-class patrol ship will be built by order of the Russian defense minister to pursue this country’s interests in the Arctic strategic area," Russian Navy Commander-in-Chief Admiral Vladimir Korolyov said, adding that the second ship in the class would be laid down soon. It will be named after polar explorer Nikolai Zubov.






ZITAT
Project 23550 ice-class patrol ship fitted with 100mm main gun and Kalibr cruise missile launchers will be closer to a corvette rather a mere patrol vessel.


ZITAT
According to open sources, the weapons suite of the Project 23550 patrol ship comprises the Kalibr (NATO reporting name: SS-N-27 Sizzler) guided missile system, guns, two Project 03160 Raptor patrol boats and a Kamov Ka-27 (Helix) helicopter. In all probability, the lead ship will lack the missile system, but the second one will differ from her in terms of weapons, and its weapons suite is yet to be decided on. The pictures published by Almaz show two Kalibr missile system modules at the stern, each comprising four launch tubes. In addition, a 76-mm AK-176MA versatile gun will be mounted at the bow. The press office of the Arsenal Company has said in March 2017 that the AK-176MA had been designed for littoral combat ships and added to the weapons suites of advanced combatants, including those in the Project 23550 class.

The weapons suite also includes two Project 03160 landing craft designed for operating near the coast round the clock. The craft are capable of landing Marines (at least 20 each) on the shore or on any other object. They can patrol assigned areas of water, intercept and seize small-size craft and conduct search and rescue. The Raptor is crewed by three and armed with a fighting module comprising a 14.5-mm machinegun, a gyro-stabilized electro-optical module and a fire control system.

The Project 23550 patrol ship can accommodate a helicopter on a helipad at the stern fore of the Kalibr launchers. Probably, the ship also has a helicopter hangar in front of the helipad. According to open sources, the ship can carry the Ka-27PL (Helix-A), but it is very likely that she also can accommodate the search-and-rescue Ka-27PS, transport/assault Ka-29 (Helix-B), radar-picket Ka-31 (Helix-E) and Ka-35, their upgraded variants and Ka-52 (Hokum-B) armed reconnaissance helicopter. The latter can use guided missiles, e.g. the Kh-31 (AS-17 Krypton) and Kh-35 (AS-20 Kayak) antiship missiles.

As of now, open sources have provided no information on the air and antisubmarine defense systems of the Russian advanced ice-rated patrol ship. Presumably, she will mount a navalized version of the Tor (SA-15 Gauntlet) surface-to-air missile system, which is in trials now, or the Pantsir-M (SA-22 Greyhound) anti-air gun/missile system. The Project 23550 patrol ship may be equipped with the Paket small-size system with 324-mm torpedo tubes and an ammunition load including anti-torpedoes. Fitting the ship with 533-mm torpedo tubes does not look reasonable. At the same time, her weapons suite should incorporate anti-torpedo rocket launchers.

DoN $180B Budget Request Emphasizes Readiness; Reduces Spending on Ships, Aircraft

THE PENTAGON – The Department of the Navy’s $180-billion budget request sets out to improve overall readiness of the Navy and the Marine Corps while making only modest asks for new aircraft and ships.

[...]

While the Navy spent the early part of the year building a public case for a larger fleet, the 2018 budget reduces the shipbuilding account by $1.2 billion, or about 6.3 percent. The budget submission includes eight new hulls in FY 2018, Deputy Assistant Secretary of the Navy for Budget Rear Adm. Brian Luther told reporters on Tuesday.

The $19.9 billion buys the last two Block IV Virginia-class attack submarines (SSN-774) for $5.2 billion and two Flight III Arleigh Burke guided-missile destroyers (DDG-51) for $3.6 billion. The destroyers would be part of a ten-ship multi-year procurement between Huntington Ingalls Industries and General Dynamics Bath Iron Works.

The budget includes a $4.4-billion increment for Ford-class carriers that includes the formal start of the third Gerald R. Ford-class aircraft carrier, Enterprise (CVN-80), and the last block of funding for the under-construction John F. Kennedy (CVN-79).

The budget also sets aside $636 million for a single Littoral Combat Ship, two less than the Navy said it would need to purchase to keep both current LCS yards viable ahead of a frigate competition leading to a construction contract award in 2020. The outlay also includes $541 million for a John Lewis-class oiler and $76 million for a T-ATS fleet tug.

The budget also set aside $1.8 billion for advanced procurement of the next generation Columbia-class nuclear ballistic missile submarine (SSBN-826).

Other major expenditures in the shipbuilding account includes $1.7 billion for the USS George Washington (CVN-73) refueling and complex overhaul, $213 million for three Ship-to-Shore Connectors, and $32 million for one LCU-1700 next-generation landing craft.

Notably absent from shipbuilding budget are funds for a new San Antonio-class amphibious transport dock (LPD-17). As part of the Fiscal Year 2017 budget, Congress included more than a billion dollars for a 13th LPD hull, which would serve as a bridge and keep the production line going ahead of the transition to the LX® program, which is based on the LPD design.

After years of resistance, the Navy has elected to adopt Congress’ plan to modernize the Ticonderoga-class guided-missile cruisers as part of the FY 2018 submission.

Under the 2/4/6 plan, “two cruisers a year would enter a modernization period that could last no longer than four years, with no more than six cruisers in the yard for modernization at any given time,” USNI News wrote last year.

The service budgeted for an additional thousand sailors to crew the additional cruisers that will not be in mothballs.

ZITAT
The search mission began two years ago after intelligence emerged that terrorists had either acquired limpet mines, which can be attached to a ship’s hull, or were planning to develop a similar device.

Navy divers involved in ‘underwater force protection operations’ – searching ships for mines – come from the SBS and from an elite team called Fleet Diving Unit 1.

A big mess with the Ford class könnte man sagen...


ZITAT
How Not to Build a Ship: The USS Ford

President Trump used the Navy’s next generation aircraft carrier, the CVN-78 USS Gerald R. Ford, as a backdrop to unveil his vision for the next defense budget in March 2017. The moment was meant to symbolize his commitment to rebuilding the military, but it also positioned the President in front of a monument to the Navy’s and defense industry’s ability to justify spending billions in taxypayer dollars on unproven technologies that often deliver worse performance at a higher cost. The Ford program also provides yet another example of the dangers of the Navy’s and industry’s end-running the rigorous combat testing that is essential to ensuring our fighting men and women go to war with equipment that works.

The Navy had expected to have the ship delivered in 2014 at a cost of $10.5 billion. But the inevitable problems resulting from the concurrency the Navy built into developing the Ford’s new and risky technologies, more than a dozen in all, caused the schedule to slip by more than three years and the cost to increase to $12.9 billion—nearly 25 percent over budget.

For all this time and money, “poor or unknown reliability of the newly designed catapults, arresting gear, weapons elevators, and radar, which are all critical for flight operations, could affect CVN-78’s ability to generate sorties, make the ship more vulnerable to attack, or create limitations during routine operations. The poor or unknown reliability of these critical subsystems is the most significant risk to CVN-78.”

US Navy receives its most expensive ship ever

The U.S. Navy has received the future aircraft carrier USS Gerald R. Ford (CVN 78), in Newport News, Virginia, May 31.

With a price tag of $12.9 billion, USS Gerald R. Ford is the most expensive ship ever built for the U.S. Navy.

It is also the first new U.S. aircraft carrier design in 40 years. Additionally, Ford is the first aircraft carrier to join the fleet since USS George H. W. Bush (CVN 77) delivered in 2009.

Delivery of the lead ship in the class followed the ship’s successful completion of acceptance trials May 26.

“Well done to our shipbuilding partners, Ford’s crew and everyone who supported them,” said Vice Adm. Tom Moore, commander, Naval Sea Systems Command, who also embarked for acceptance trials.

Ford will be commissioned into the fleet this summer, formally placing the ship into active service.

Following this, there will be a “shakedown” period where the ship will conduct several at-sea events to provide longer underway periods for the ship’s crew to operate and train on ship’s systems.

In addition, planned deferred work will be performed, and any deficiencies identified during trials will be addressed during in-port periods.

Ford is expected to be operational in 2020 following achievement of initial operational capability.

The Ford-class features a new nuclear power plant, a redesigned island, electromagnetic catapults, improved weapons movement, an enhanced flight deck capable of increased aircraft sortie rates. Ford-class ships will operate with a smaller crew than a Nimitz-class carrier and are expected to provide $4 billion in total ownership cost savings for the Navy.

Na ja, die erhöhten Entwicklungskosten habe ich hauptsächlich beim Typschiff der Klasse. Die geringeren Betriebskosten bei gleichzeitig up to date Systemen kommt der ganzen Klasse zugute.

Es könnten noch nachträgliche Umbauten auf die Folgeschiffe dazu kommen, wenn sich die Navy entschließt Systeme umzuplanen oder umzubauen, die in der Ford nicht in den Griff zu bekommen sind. So wie es aussieht, wird es sogar dazu kommen. Damit kann man die Einsparung vergessen. Unter dem Strich ist alles weit teurer als geplant. Ein großes Problem ist aber die Nutzbarkeit des Schiffes. Ein kleiner Defekt des EMALS durch Feindeinwirkung und es ist ein mission kIll. Dass man im Zivilleben Bananenware ausliefert, mag noch gehen, sofern man das akzeptiert. Aber, dass man Waffen als Bananenware ausliefert, die im Notfalls gar nicht funktionieren, oder nur stark eingeschränkt und dazu noch Gefahr laufen bei der kleinsten Beanspruchung auszufallen, das ist schon fahrlässig.

Ein kleiner Defekt am Dampfkatapult der Nimitz wäre auch ein Mission Kill. Wo ist also das Problem?

Du hast den Artikel scheinbar auch nicht gelesen, da geht es primär um die Zuverlässigkeit (reliability) im typischen Betrieb und nicht um Gefechtsschäden. Letzteres (respektive deren angeblich problematischere Reparatur) wird zwar einige Male kurz angesprochen, aber es wird gleich wieder relativiert ("risks [..] cannot be assessed until the completion of operational testing in 2020.", "risk cannot be assessed until operational testing is finished.", "All of these systems have yet to be pitted against [..] Full Ship Shock Trials"). Und am Ende wird nochmal die Diskussion aufgemacht, ob man Träger wirklich noch braucht.

Das Ganze ist ein Meinungsstück.
