about kockums A26 gripenSSN hawa mein teerbaazi less said the better. that one did not weigh anchor off the drawing board even.

and yet the old hats massa and bear continue to churn them out - big, fast and quiet.


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Now the main thing – China’s RIMPAC invitation was revoked in May.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]

electric boat co of groton as the worlds bleeding edge SSN builder seems to be fixer of choice when things head south and people get in over their heads

the aussies collins underwater noise and hull issues were also fixed by electric boat.

I think it is the Dutch De Zeven Provinciën-class frigate, very pleasing to the eye.

+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?

as a footnote, read this glowing prediction of fuel cells for consumer use from 2004 https://www.forbes.com/2004/06/22/cx_ah ... e026634f0b

fujitsu toshiba , sanyo etc had come up with fuel cells for laptops :shock:
