  • Trump, 79, Gets Confused Explaining Water to the Navy

    Jump

  • They would have way more parts, fail more catastrophically

    This remains to be seen. In fact, the opposite is proving true.

    https://maritime-executive.com/article/report-carrier-uss-ford-s-electromagnetic-systems-still-need-work

    USS Ford's launch and recovery gear are electromagnetically actuated, a departure from the steam-operated Nimitz-class carriers. The new designs were developed and installed because they promised longer intervals between maintenance and higher sortie generation rates. Though the Navy remains upbeat about Ford's capabilities, these gains have proven elusive. "The reliability of CVN 78 catapults, arresting gear, and jet blast deflectors (JBDs) continues to have an adverse effect on sortie generation and flight operations efficiency," noted DOT&E in an annual report released in mid-January. "The ongoing reliability problems with these critical subsystems remains the primary risk to the successful completion of CVN 78 [initial operational testing and evaluation]."

    The carrier's Advanced Arresting Gear (AAG) has similar challenges. The AAG is supposed to cycle 16,500 times between failures, but in recent testing it has broken down after roughly 450 cycles.

    Belowdecks, the Ford's Advanced Weapons Elevator (AWE) elevator system remains a source of trouble. During a weapons onload in September, the lower stage elevators performed more quickly than those on a Nimitz-class carrier, DOT&E said; however, 109 elevator failures were reported out of about 20,000 elevator dispatches. "AWE system reliability will be critical as the Navy develops standard procedures for moving ordnance from magazines to the flight deck," noted DOT&E.

    In a first ordnance-handling test, the advanced weapons elevators on the USS Gerald R. Ford (CVN 78), America’s new, $13.3 billion supercarrier, offered little to no meaningful improvement over the legacy elevator systems aboard America’s venerable $5 billion Nimitz class carriers.

    Crew claimed they “were able to run ammo downstairs in the magazines much quicker because we were able to put extra weight on the elevator, able to run it down quicker, which means you have to run those cycles a lot less.” That sounds great, but unbiased analysis of the Ford’s performance during the carrier’s initial two-and-a-half day ammunition onload cycle suggests the Navy has yet to take full advantage of Ford’s eleven faster and stronger elevators. Put bluntly, all the high-tech electromagnetic elevators aboard the USS Ford failed to translate into a faster ordnance onload cycle. It calls a primary pillar of the Ford’s business case—that new ammunition handling techniques would yield vast performance benefits and make the ship less vulnerable—into question.

  • It actually does matter when you have an entire thread of people decrying Trump's supposed lack of understanding of magnets - while simultaneously pushing completely incorrect ideas about magents and laying bare their own lack of understanding of magnets.

    Especially annoying when you can do one single Google search and read a plethora of sources that explain in great scientific detail just how susceptible magnets are to water - especially in seawater applications.

  • Giving rare earth magnets a waterproof coating is nothing new. They are still extremely susceptible to corrosion, especially in seawater applications.

  • Which is 100 percent correct... you can drop a single drop of tap water onto a magent, and it will corrode. This is nothing new to aquarium enthusiasts.

    Did he say it like a dumbass? Yes. Is he a dumbass? Yes. But there is truth to what he's saying. Criticisms of the man should be strategic and pointed, otherwise you risk discrediting yourself to right wingers.

  • ... rare earth magnets are highly susceptible to corrosion regardless if the water is salty. They will corrode very quickly in fresh water - as any aquarium hobbyist coult tell you.

    You aren't claiming that magnets are impervious to corrosion, are you?

    Neodymium magnets are typically coated with Nickel to prevent rust and corrosion from moisture, but unless coated with a special corrosion resistant coating, they are not waterproof. They should be kept away from water (especially salt water), as exposure to moisture can cause them to corrode and lose their magnetic strength over time. It is important to note that even a small amount of water, such as high humidity, can cause rust to form on the surface of the magnets. If you need to use neodymium magnets in a damp or wet environment, it is best to use a magnet with a corrosion resistant coating, or encase them in a waterproof container to protect them from moisture.

  • Saltwater does in fact aggressively corrode neodymium magnets. About as fast as a piece of raw iron. On top of that, the saltwater can induce currents in magnetic systems that can wreak havoc. There is truth to what Trump is saying. It seems like people are assuming Trump thinks water cancels out magnetism, but I don't see that.

  • [you are] posting exclusively propaganda sources

    https://theindiaobserver.com/islamic-delegation-visiting-chinas-xinjiang-region-says-all-is-well-here/

    The Western media narrative is, “China’s Xinjiang policy has included intrusive surveillance, religious restrictions, the destruction of mosques, arbitrary arrests, and the detention of an estimated 1.8 million mostly Muslim Uyghurs and other Turkic peoples in a vast network of internment camps and prisons. Some have been subjected to sexual assaults, forced labor, and forced sterilizations.”

    In order to counter this narrative an Islamic delegation that compromised of members from Saudi Arabia, UAE, Egypt, Syria, Bahrain, Tunisia, and Bosnia and Herzegovina visited the Xingjiang region.

    Dr. Osama Sayyid Al Azhari, the Egyptian President’s Advisor on Religious Affairs said “I believe that this visit demonstrates that China has attached great significance to preserving the ethnic culture with racial distinctions of many nationalities in Xinjiang province.”

    Dr. Mustafa Ceric, former Mufti of Bosnia and Herzegovina said “What we’ve heard outside China surely has a bias. I’d say Muslim communities in China include more than Uygurs and there’re more than ten Muslim groups such as Hui and Mongolian and others in the region.”

  • I'm willing to accept the most viable candidate that will fight MAGA.

    I could give you a magic button that removes any and all traces of MAGA from the US, but American fascism would eventually fester again under a new name. American fascism is the only logical conclusion to a country that was founded solely by 20-something, white, enslaving, rich, male landowners. You blue maga types are not at all opposed to the death and destruction that the US has carried out outwardly for the past 200 years - you just care all of a sudden now that the violence has been pointed inwards and your brunch has been interrupted. Blue maga is not about addressing the contradictions that allow fascism to fester, but just about reclaiming American patriotism. MAGA is not the enemy. Capitalism is. And until you obtain revolutionary politics, youre doomed to keep descending into fascism until the cows come home.

  • The three sources you posted are all the same. They all come from the ICIJ report - whose contents was originally shared by Adrien Zenz. You know, the Christian Findamentalist who said Hitler was an effective crime fighter? It's laughable with all of these anti China hit pieces. You never need to go more than one or two sources back before youre hitting radio free Asia or adrien zenz. What you assumed were three sources was actually the same regurgitated slop that's been juggled between sources for the past 5 years.

    GT: You visited China's Xinjiang region in 2019, 2023 and again this August. Looking back, how would you compare your impressions from these trips? What changes stood out to you most in terms of development and social stability?

    Al Nuaimi: In all three visits I met officials, community representatives, religious leaders, and visited mosques and families, especially during the first trip. I see progress, I see real development. The government has a plan for reducing poverty, and I witnessed the results on the ground, not just what officials told me.

    It's important to appreciate this achievement, to acknowledge it and to show the world that while many countries face challenges, in China, especially in this region, there has been remarkable progress. People outside China cannot imagine the lifestyle here or the services provided to the people of Xinjiang.

  • It is especially strange how the article pushes this conspiracy theory

    However, he claimed, the overall practice is driven by a programme called Project 981, which aims to increase the life expectancy of CCP leaders to 150 years and includes free access to organ transplants. “It explains why this hideous crime exists and why it is flourishing. It needs to flourish so the leaders will have a pool of organs to choose from.”

    I found one single reference to a "project 981" on the internet, and it comes back to a Radio Free source. Laughable conspiracy theories with zero backing. Par for the course for these anti China hit pieces.
