Yes, amazing how Navantia with its vast experience can miss the dock size for its reworked sub! They’re the partners with L&T on our LPD project so hopefully they don’t goof up this time.

Just shows how hard making this stuff is.

Nice posts.

I like the Korean one and Unkil’s Burke Flight III (shielded funnels) the best as the most visually appealing.

RIMPAC-2018: What Makes It So Special This Year?

https://www.zerohedge.com/news/2018-07- ... ecial-year

It involves 46 surface ships, five submarines, 18 national land forces, more than 200 aircraft and 25,000 personnel from twenty five nations. Defending sea lanes is the main mission and there are always political connotations.

This is also the first time a US newly created regional command is overseeing the exercise. On May 30, Secretary of Defense James Mattis announced that US Pacific Command (PACOM), which oversees all US military forces in Asia, had changed its name to be called the Indo-Pacific Command (INDOPACOM) to reflect “the increasing connectivity between the Indian and Pacific Oceans,” as well as America’s determination to remain the dominant power in both.

Now the main thing – China’s RIMPAC invitation was revoked in May. China first participated in the RIMPAC exercises in 2014. The formal reason given by US military is the “militarization” of artificial islands in the South China Sea. Secretary Mattis said he did not expect countries to choose between the US and China "because a friend does not demand you choose among them." The Chinese Navy has sent a Type 815 intelligence gathering ship to observe the exercise.

The list of nations invited to the RIMPAC-2018 obviously reflects the US desire to strengthen its military ties with states on China’s perimeter in an effort to confine it. The US opposes China’s ambitious “One Belt, One Road” economic initiative and encircling the country with US-friendly actors is a vital component of the policy to counter it.

The US is testing its combat capability in the two oceans and is doing it with numerous partners. This month, USS Essex amphibious assault ship (jump-jet carrier) with Marine Corps F-35Bs onboard sailed into the Pacific – the second ever deployment of small-deck flattop with the new the aircraft onboard. The F-35 aircraft is known for its stealth design and advanced sensors and controls. Israel was the first nation to ever use the F-35 in combat. This year, it sent the stealth aircraft to attack Iranian training bases and weapons depots in Syria. The plans to sell F-35s to Taiwan are under consideration in the United States. If the deal goes through, the relations with China will greatly deteriorate - the eventuality RIMPAC is taking into account. The voices inside Congress are calling for approval of the sale.

Spain's New Submarine Is Too Big To Fit In Its Dock

El País reported on Wednesday that Spain’s struggling new S-80 submarine procurement programme had run into another problem. After previously being found too heavy to resurface, the boats, which are 81m long and weigh 3,000-tons, were now too long to fit in the submarine pens at the Cartagena naval base, meaning millions would need to be spent extending them. The submarines were lengthened—and re-baptised the S-80 Plus—to fix the weight problem.

“The MoD will have to make the docks at the Cartagena base bigger because the new submarine doesn’t fit”, the paper headlined, reporting the new €16 million overrun would go into the nearly €4 billion project cost, or nearly a billion euros per submarine.

China Building 8 Submarines For Pakistan, As China-Pak Projects Flourish

Chinese shipbuilders are constructing eight new submarines to protect its ally Pakistan with an aim to counter India. Currently, Pakistan’s Navy has ten subs, which suggests their submarine fleet could expand by 80 percent upon delivery, expected in the mid to late 2020s. Relations between both countries are incredibly complex, as the Kashmir conflict and the numerous military disputes on the Line of Control (LoC) have intensified in recent years.

According to unnamed sources, as quoted per Zee News, under Project Hangor, China’s shipbuilding industry could soon be delivering over eight new subs to Pakistan. India’s underwater warfare program is perceived to be far superior to Pakistan. As of now, India has sixteen submarines while Pakistan has about ten. However, China wants to scale up Pakistan’s underwater warfare capabilities to defend the China Pakistan Economic Corridor (CPEC).

In addition to submarines, China successfully launched two remote sensing satellites for Pakistan last week, which could help both countries monitor India and CPEC infrastructure. The satellites were on-board the Chinese Long March (LM-2C) spacecraft, while the PRSS1 – Pakistan’s first optical remote sensing unit – was developed by the China Academy of Space Technology (CAST).

Furthermore, the fiber optic pipeline project connecting Pakistan to China was completed in June which now provides a direct link between Pakistan, Middle Asia, and East Asia and reduces the possibility of disruption to international traffic. This is amongst the only information and communication technology project under the CPEC. The project started in March 2016 and concluded last month. The cable extends over a distance of 509 miles and has 26 microwave transmission nodes from Rawalpindi to Karimabad and 106 miles of aerial fiber cable from Karimabad to Khunjerab as a back-up.

their AIP system with flammable hydrogen looks dodgy to me, vs the soothing Li-Ion plans of the Soryu++ :)

Wiki:

The AIP (air independent propulsion) implemented on the S-80 is completely different from the French MESMA (Module Energie Sous-Marin Autonome) project. The S-80's AIP system is based on a bioethanol-processor (provided by Hynergreen from Abengoa) consisting of a reaction chamber and several intermediate Coprox reactors, that will transform the BioEtOH into high purity hydrogen. The output feeds a series of fuel cells from UTC Power company (which also supplied fuel cells for the Space Shuttle).

The Reformator is fed with bioethanol as fuel, and oxygen (stored as a liquid in a high pressure cryogenic tank), generating hydrogen and carbon dioxide as subproducts. The produced hydrogen and more oxygen is fed to the fuel cells.

The bioethanol-processor also produces a stream of highly concentrated carbon dioxide and other trace gases that are not burned completely during combustion. This gas flow is mixed with sea water in one or more ejector venturi scrubber and then through a new system called SECO2 (or CO2 Removal System), developed by Bionet, and whose purpose is to dissolve the "bubbles" of CO2 in water to undetectable levels.[8]

The oxygen and fuel flow rates are directly determined by the demand for power. The AIP power in the S-80 submarine is at least 300 kW.[8] A permanent-magnet electric motor moves a fixed propeller of a special design, that doesn't create cavitations at high speed.


--

With the project also suffering with an underperforming AIP system (which was to allow the submarine to stay underway for 28 days but was only managing 21 days) the Spanish Defence Ministry announced in June 2013 that Navantia has signed on the US company General Dynamics Electric Boat to help solve the excess weight.[22] In September 2014, the detected overweight was reported to have been resolved and the construction work to be ready to resume in late October 2014.[23] In November 2014, Navantia again reported having completed the redesign work to address the problem of overweight. In all, the hull will be lengthened by seven metres, and the displacement increased by 75 tons. As of January 2018, the intended delivery date of the first submarine is September 2022.[24] In January 2017, it was reported that the AIP system would not be ready in time for the delivery of the first submarine.[25]

+1, Hydrogen fuel-cells might have sounded cool 10-15 years ago but they have long lost the battle against Li-Ion batteries in commercial applications (automobiles etc.) and is only going to get worse in the future with battery technology improving due to huge investments being made and fuel cells being relegated to niche roles. Chemical fuels still have an advantage of being more energy dense than batteries (some thing like 5x) but the complexity of converting that energy via fuel cells is insane. I mean WTF how do you replenish a sub with cryogenic oxygen?

Cruise missiles and aircraft are increasingly gaining a stronghold in the region as China modernizes its air-force. The current SM6 is quite a versatile weapon capable of long-range AAW (stated range of 200 nautical miles / 350+ km), Ballistic Missile intercept (up to MRBM class) and even surface warfare.

Given that Japan is an SM-3 Block II customer and dev. partner, the SM6 block IB (being funded by USN) with its 21" rocket motor and body (borrowed from the SM3 II) will look quite atractive. Should easily move the missile into an IRBM-interceptor class and extend extreme long range intercepts (AAW..cooperative target) to well beyond 450 km. This will be a major pain in the a$$ for China especially since Japan is an AEGIS, E-2D and F-35 operator which lends itself nicely to having a similar capability to what the US Navy enjoys with NIFC-CA with its ability to do OTH intercepts.

Japan’s Improved Atago-class to field SM-6 air-defence missiles


The Ministry of Defense (MoD) in Tokyo has decided to equip the Japan Maritime Self-Defense Force’s (JMSDF’s) two Improved Atago-class destroyers with Standard Missile 6 (SM-6) air-defence missiles, an MoD spokesperson told Jane’s on 3 September.

The revelation comes just four days after the MoD asked for JPY11.1 billion (USD99.9 million) in its 2019 budget request to procure an undisclosed number of SM-6 interceptors, and JPY2.1 billion to acquire additional ones for testing.The decision follows the launch of Maya (with pennant number 179) on 30 July, the first of the two Improved Atago-class destroyers. The 170 m-long vessel entered the water at the Japan Marine United (JMU) Corporation’s facility in Yokohama and is expected to be commissioned in March 2020, while the second ship is expected to enter service in March 2021.

The vessels will be equipped with the US-developed Cooperative Engagement Capability (CEC) system, which will enable the destroyers to act as part of a wider ‘grid’ of sensor and weapon platforms that allows other CEC-equipped ships to share surveillance and targeting information.

The ships, which are 5 m longer than the Atago-class destroyers, will also field SM-3 Block IIA missiles designed to intercept short- and intermediate-range ballistic missiles.

The MoD is advancing Japan's integrated air and missile defence (IAMD) capabilities through the combined use of Aegis-equipped vessels, early-warning aircraft, radars, and other equipment.

Maya is expected to use the Aegis Baseline J7 supported by the Lockheed Martin AN/SPY-1D-series radar.

At the Yokosuka naval base in Kanagawa Prefecture the US Navy’s 7th Fleet has already deployed CEC-capable Aegis ships that can launch SM-6 interceptors.

The commissioning of Maya in 2020 is expected to facilitate data-sharing with US warships and enhance the interoperability between the Japan Self-Defense Force and the US military.

The latest revelation comes six days after Tokyo referred in its Defense of Japan 2018 White Paper to North Korea’s ballistic missile programme as an “unprecedentedly serious and imminent threat to Japan’s security”.

Japan is promoting a ‘cross-domain strategy’ aimed at establishing superiority in the air, at sea, on land, and in outer space as well as in electronic warfare and cyber space. The SM-6 system will be part of this strategy as well as part of the IAMD initiative.

For example, SM-6 missiles will be used for protecting the two land-based Aegis Ashore ballistic missile defence (BMD) systems set to be operated by the Japan Ground Self-Defense Force.


Once Maya is commissioned in 2020 the JMSDF is likely to carry out an interception test in the United States using SM-6 missiles. It is usual for the JMSDF to conduct such test in the United States.

Chinese Fishermen Wage "Hybrid War" On Asian Seas

Image

The U.S. Department of Defense’s annual report to Congress, released in August, detailed military and security developments of the Chinese armed forces and drew attention to the “People’s Armed Forces Maritime Militia” (PAFMM), a weaponized fishing fleet funded by Beijing - a new asset for low-intensity maritime confrontations, and a forward screen for its growing military force in the South China Sea.

Nice programme on how submarines operate.

"Know Your Enemy
The Silent War Episode 1 of 2

For decades, Britain and America's Cold War submarines waged a secret war of espionage against the Soviet navy. Deep in the ocean, crews were locked in a game of cat and mouse as each side battled to gain the tactical and technological advantage."

US could use Navy for ‘blockade’ to hamper Russian energy exports – Interior Secretary

US could use its Navy to prevent Russia’s potential energy supplies to the Middle East, Internal Secretary Ryan Zinke said, Washington Examiner reports. The blockade would actually mean an “act of war,” Russian Senator fired back.
Zinke alleged that Russia’s engagement in Syria – notably, where it is operating at the invitation of the legitimate government – is a pretext to explore new energy markets.

"I believe the reason they are in the Middle East is they want to broker energy just like they do in eastern Europe, the southern belly of Europe,” he has reportedly said.

And, according to to the official, there are ways and means to tackle it.

"The United States has that ability, with our Navy, to make sure the sea lanes are open, and, if necessary, to blockade ... to make sure that their energy does not go to market," he said.

Zinke was addressing the attendees of the event hosted by the Consumer Energy Alliance, a non-profit group which styles itself as the “voice of the energy consumer” in the US. He went to compare Washington's approaches to dealing with Russia and Iran, noting that they are effectively the same.

"The economic option on Iran and Russia is, more or less, leveraging and replacing fuels,” he said, while referring to Russia as a “one trick pony” with an economy dependent on fossil fuels.

Zinke’s statements provoked an angry response from Moscow, which equated a potential maritime blockade to an “act of war,” while calling the internal secretary’s assumptions “nonsense.”

“A US blockade of Russia would be equal to a declaration of war under international law,” Russian Senator Aleksey Pushkov said, commenting on Zinke’s words. Russia does not currently export any energy to the Middle East, which itself is a major oil exporting region. The whole idea is an “absolute nonsense,” the Senator argued.

The comment from the US Interior Secretary come as Trump administration has been on a mission to boost the export of its liquefied natural gas to Europe, replacing Russia, the far cheaper option for European consumers. For that effect, the Trump administration officials, including US President Donald Trump himself, try to persuade Germany to pull out of the “inappropriate” Nord Stream 2 pipeline project, which according to Trump, made Berlin Moscow’s “captive.”

From twitter - Nammo @Nammo

NAMMO - The Bullet That Swims Through Water

Ammunition that can be fired into water, without stopping or changing course. Look closely, and you can see the tracer still burning! Already in full production for both the US Navy and Army.


From the NAMMO website - link

While traditional ammunition is either stopped or deflected when it hits water, Nammo’s 30 mm Swimmer (APFSDS-T MK 258 Mod 1) swims straight through water, thanks to a groundbreaking design on the supercavitating projectile developed in cooperation with the US Navy.


The Swimmer round falls into the category of sub-caliber kinetic energy penetrators. These can most easily be described as arrows made out of very heavy materials that use the force of the impact rather than explosives to punch through armor. Traveling at speeds of more than 1 km per second, the energy generated by the impact melts the armor of the vehicle into a fluid and the arrow “swims” through the armored side of the vehicle. In the case of the Swimmer, the force of the arrow is sufficient to defeat anything except main battle tanks.


Nammo’s penetrators, both for vehicles and other types of armor piercing ammunition, are made out of a super tough tungsten alloy, also known as wolfram. More than two times as heavy as steel, it has the second highest melting point of any element, making it ideal for use in armor piercing ammunition.


What makes the Swimmer unique, however, is the combination of powerful armor penetration and its ability to swim straight through water. This effect has until now been considered impossible to achieve by ammunition fired from air through water.


This enables the Swimmer to be used in defense of either ships or coastal areas against submerged and surface mines, small underwater vehicles, torpedoes and even small fast attack crafts that might be concealed by waves. This is valuable not only for naval vessels, but also for land vehicles defending harbors, bridges or other key locations.
