The Insane Engineering of the M1 Abrams

robdot says...

The new defense spending bill includes $120 million for tanks that the Army has repeatedly said it doesn't want.

For three years, the Army in numerous Congressional hearings has pushed a plan that essentially would have suspended tank building and upgrades in the U.S. for the first time since World War II. The Army suggested that production lines could be kept open through foreign sales.

Each time, Congress has pushed back. Last week, Congress won again in the National Defense Authorization Act (NDAA) for Fiscal Year 2015.

In a statement, Rep. Mike Turner, R-Ohio, said that Congress "recognizes the necessity of the Abrams tank to our national security and authorizes an additional $120 million for Abrams tank upgrades. This provision keeps the production lines open in Lima, Ohio,……

IQ testing and the eugenics movement in the United States

Eugenics, a set of beliefs and practices aimed at improving the genetic quality of the human population by excluding people and groups judged to be inferior and promoting those judged to be superior,[39][40][41] played a significant role in the history and culture of the United States during the Progressive Era, from the late 19th century until US involvement in World War II.[42][43]

The American eugenics movement was rooted in the biological determinist ideas of the British Scientist Sir Francis Galton. In 1883, Galton first used the word eugenics to describe the biological improvement of human genes and the concept of being "well-born".[44][45] He believed that differences in a person's ability were acquired primarily through genetics and that eugenics could be implemented through selective breeding in order for the human race to improve in its overall quality, therefore allowing for humans to direct their own evolution.[46]

Goddard was a eugenicist. In 1908, he published his own version, The Binet and Simon Test of Intellectual Capacity, and cordially promoted the test. He quickly extended the use of the scale to the public schools (1913), to immigration (Ellis Island, 1914) and to a court of law (1914).[47]

Unlike Galton, who promoted eugenics through selective breeding for positive traits, Goddard went with the US eugenics movement to eliminate "undesirable" traits.[48] Goddard used the term "feeble-minded" to refer to people who did not perform well on the test. He argued that "feeble-mindedness" was caused by heredity, and thus feeble-minded people should be prevented from giving birth, either by institutional isolation or sterilization surgeries.[47] At first, sterilization targeted the disabled, but was later extended to poor people. Goddard's intelligence test was endorsed by the eugenicists to push for laws for forced sterilization. Different states adopted the sterilization laws at different paces. These laws, whose constitutionality was upheld by the Supreme Court in their 1927 ruling Buck v. Bell, forced over 60,000 people to go through sterilization in the United States.[49]

California's sterilization program was so effective that the Nazis turned to the government for advice on how to prevent the birth of the "unfit".[50] While the US eugenics movement lost much of its momentum in the 1940s in view of the horrors of Nazi Germany, advocates of eugenics (including Nazi geneticist Otmar Freiherr von Verschuer) continued to work and promote their ideas in the United States.[50] In later decades, some eugenic principles have made a resurgence as a voluntary means of selective reproduction, with some calling them "new eugenics".[51] As it becomes possible to test for and correlate genes with IQ (and its proxies),[52] ethicists and embryonic genetic testing companies are attempting to understand the ways in which the technology can be ethically deployed.[53]

Marvel Studios' Black Widow - Official Teaser Trailer

Sagemind says...

For those who are interested:

The Red Guardian
"Alexi Shostakov was one of the Soviet Union's most acclaimed test pilots whose heroism caught the attention of the KGB. They arranged for Shostakov to wed Natasha Romanoff , a top agent of the secret Red Room Academy, later known as the Black Widow. Intending to manipulate Natasha years after the couple’s marriage the KGB arranged for a rocket Shostakov was supposedly piloting to exploded, giving the appearance of his apparent death.

Shostakov’s “death” drove Natasha deeper into the Red Room’s service, although, in reality Shostakov, was alive and recruited into the KGB. He was given the identity of the Red Guardian, a costumed heroic guise first assigned to Aleksey Lebedev (aka Volodymyr Fomin) during World War II by Soviet Premier Josef Stalin, but the costume had become the property of the Red Room. Through the Red Guardian, the Russians hoped to hone a national hero to represent them just as Captain America (Steve Rogers) represented the USA. During Shostakov’s training the Black Widow, who was again using her maiden name turned against her superiors, and defected to the USA, becoming romantically involved with Hawkeye (Clint Barton) of the Avengers."

SFOGuy says...

That might be, weirdly, the source of a confused correlation for some voters. Living standards for middle class voters ("my kid can do better than me") continued to rise through about the mid to late 1970s---and after that, flat-lined for a more than a generation, all the way to today.

The correlation that some people draw is "immigrants", "civil rights", etc...

Though, perhaps, academics might point them in a different direction---trade, tax policy, the decline of unions (driving middle class wages) in the face of a shifting industrial base, technological change, and the rise of competitors who finally recovered from World War II...

It would be nice if there was a rising tide that lifted all middle class (of all backgrounds) households still...

Hypersonic Missile Nonproliferation

Mordhaus says...

A big part of the Zero's reputation came from racking up kills in China against a lot of second-rate planes with poorly-trained pilots. After all, there was a reason that the Republic of China hired the American Volunteer Group to help out during the Second Sino-Japanese War – Chinese pilots had a hard time cutting it.

The Wildcat was deficient in many ways versus the Zero, but it still had superior firepower via ammo loadout. The Zero carried very few 20mm rounds, most of it's ammo was 7.7mm. There are records of Japanese pilots unloading all their 7.7mm ammo on a Wildcat and it was still flyable. On the flip side, the Wildcat had an ample supply of .50 cal.

Stanley "Swede" Vejtasa was able to score seven kills against Japanese planes in one day with a Wildcat.

Yes, the discovery of the Akutan Zero helped the United States beat this plane. But MilitaryFactory.com notes that the Hellcat's first flight was on June 26, 1942 – three weeks after the raid on Dutch Harbor that lead to the fateful crash-landing of the Mitsubishi A6M flown by Tadayoshi Koga.

Marine Captain Kenneth Walsh described how he knew to roll to the right at high speed to lose a Zero on his tail. Walsh would end World War II with 17 kills. The Zero also had trouble in dives, thanks to a bad carburetor.

We were behind in technology for many reasons, but once the Hellcat started replacing the Wildcat, the Japanese Air Superiority was over. Even if they had maintained a lead in technology, as Russia showed in WW2, quantity has a quality all of it's own. We were always going to be able to field more pilots and planes than Japan would be able to.

As far as Soviet rockets, once we were stunned by the launch of Sputnik, we kicked into high gear. You can say what you will of reliability, consistency, and dependability, but exactly how many manned Soviet missions landed on the moon and returned? Other than Buran, which was almost a copy of our Space Shuttle, how many shuttles did the USSR field?

The Soviets did build some things that were very sophisticated and were, for a while, better than what we could field. The Mig-31 is a great example. We briefly lagged behind but have a much superior air capability now. The only advantages the Mig and Sukhoi have is speed, they can fire all their missiles and flee. If they are engaged however, they will lose if pilots are equally skilled.

As @newtboy has said, I am sure that Russia and China are working on military advancements, but the technology simply doesn't exist to make a Hypersonic missile possible at this point.

China is fielding a man portable rifle that can inflict pain, not kill, and there is no hard evidence that it works.

There is no proof that the Chinese have figured out the technology for an operational rail gun on land, let alone the sea. We also have created successful railguns, the problem is POWERING them repeatedly, especially onboard a ship. If they figured out a power source that will pull it off, then it is possible, but there is no concrete proof other than a photo of a weapon attached to a ship. Our experts are guessing they might have it functional by 2025, might...

China has shown that long range QEEC is possible. It has been around but they created the first one capable of doing it from space. The problem is, they had to jury rig it. Photons, or light, can only go through about 100 kilometers of optic fiber before getting too dim to reliably carry data. As a result, the signal needs to be relayed by a node, which decrypts and re-encrypts the data before passing it on. This process makes the nodes susceptible to hacking. There are 32 of these nodes for the Beijing-Shanghai quantum link alone.

The main issue with warfare today is that it really doesn't matter unless the battle is between one of the big 3. Which means that ANY action could provoke Nuclear conflict. Is Russia going to hypersonic missile one of our carriers without Nukes become an option on the table as a retaliation? Is China going to railgun a ship and risk nuclear war?

Hell no, no more than we would expect to blow up some major Russian or Chinese piece of military hardware without severe escalation! Which means we can create all the technological terrors we like, because we WON'T use them unless they somehow provide us a defense against nuclear annihilation.

So just like China and Russia steal stuff from us to build military hardware to counter ours, if they create something that is significantly better, we will began trying to duplicate it. The only thing which would screw this system to hell is if one of us actually did begin developing a successful counter measure to nukes. If that happens, both of the other nations are quite likely to threaten IMMEDIATE thermonuclear war to prevent that country from developing enough of the counter measures to break the tie.

When you have neither speed nor maneuverability, it's your own durability that is in question, not the opponents durability.

It took the capture of the Akutan zero, its repair, and U.S. flight testing, to work out countermeasures to the zero.

The countermeasures were basically :
- One surprise diving attack and run away with momentum, or just don't fight them.
- Else bait your pursuer into a head-on pass with an ally (Thatch weave) (which, is still a bad position, only it's bad for everyone.)

Zero had 20mm cannons. The F4F had .50's. The F4F did not out gun the zero. 20mms only need a couple rounds to down a plane.

Durability became a factor later in the war, after the U.S. brought in better planes, like the F4U, F6F, Mustang, etc... while the zero stagnated in near-original form, and Japan could not make planes like the N1K in meaningful quanitties, or even provide quality fuel for planes like the Ki84 to use full power.

History is history. We screwed up at the start of WW2. Hubris/pride/confidence made us dismiss technologies that came around to bite us in the ass hard, and cost a lot of lives.




Best rockets since the 1960's? Because it had the biggest rocket?
What about reliability, consistency, dependability.
If I had to put my own life on the line and go to space, and I had a choice, I would pick a Russian rocket.

Freezing 200,000 Tons of Lethal Arsenic Dust

Sagemind says...

"In the summer of 1935, C.J. "Johnny" Baker and H. Muir staked the original 21 "Giant" claims for Bear Exploration Company. The claims were on Great Slave Lake's Back Bay and along what is now the historic Ingraham Trail.

By 1937, Yellowknife Gold Mines Ltd. acquired Burwash's assets. From these, the subsidiary Giant Yellowknife Gold Mines Ltd was created. The company fell on hard times and by 1940, operations eventually came to a standstill. Frobisher Explorations took over the site in 1943. However, the advent of World War II halted the operation once again. Gold was not a priority in times of war, and there was a shortage of men to work the site.

Soon after the war ended, Giant Mine officially opened, and production moved into full swing. The first gold brick was poured on June 3, 1948.

From May to December 1948, the mine produced 8,152 ounces of gold from 49,985 tonnes of ore. With the nearby Con Mine also operating, Yellowknife was experiencing the rapid growth associated with a booming mining industry.

Those original claims would lead to the production of seven million ounces of gold and one of the longest continuous gold mining operations in Canadian mining history; however, they also led to a legacy of contamination."

Don Lemon is not having it

heropsycho says...

You can't possibly argue that the Pocahontas thing while at an event intending to honor Native Americans is acceptable behavior. If he thinks Warren is lying about her heritage, fine. Say she's lying about it some other time. Nobody put a gun to Trump's head and said he has to call her that. And on top of all that, at least have the courtesy to not do it at that event. Honoring World War II Native American veterans has jack shit nothing to do with Elizabeth Warren.

Even if you happen to think that there's nothing wrong with the Washington Redskins name, do you think it would be appropriate for the President of the United States to bust through the wall Kool Aid man style dressed head to toe in Redskins garb doing the Tomahawk Chop at an event intended to honor Native Americans? FFS!

What next? Meet with a Chinese delegation and walk in doing slant eyes and the ol' "Chinese, Japanese, dirty knees, *lift shirt* LOOK AT THESE!!!"

All he had to do was turn his "be a dick" switch off for a few hours to honor war veterans. Is that so hard? Apparently, it's impossible for him.

Watching this guy as President is just astounding to me. Every damn day seemingly he finds new ways to be a total dick when he completely doesn't have to be. Elizabeth Warren is going to be fine, I don't care he insulted her. But acting like an ass clown in a way that's very likely to offend actual war heroes in the process?! Zero justification, zero excuses.

Being President isn't supposed to be a 24/7 reality TV show where everything revolves around petty partisan/personal vendettas, including disregarding basic tenets of acting like a mature adult.

Cassowary attacks

Cassowaries have a reputation in folklore for being dangerous to people and domestic animals. During World War II American and Australian troops stationed in New Guinea were warned to steer clear of them. In his book Living Birds of the World from 1958, ornithologist Ernest Thomas Gilliard wrote:

The inner or second of the three toes is fitted with a long, straight, murderous nail which can sever an arm or eviscerate an abdomen with ease. There are many records of natives being killed by this bird.

This assessment of the danger posed by cassowaries has been repeated in print by authors including Gregory S. Paul (1988) and Jared Diamond (1997). A 2003 historical study of 221 cassowary attacks showed that 150 had been against humans. 75% of these had been from cassowaries that had been fed by people. 71% of the time the bird had chased or charged the victim. 15% of the time they kicked. Of the attacks, 73% involved the birds expecting or snatching food, 5% involved defending natural food sources, 15% involved defending themselves from attack, and 7% involved defending their chicks or eggs. The 150 attacks included only one human death.

The one documented human death was caused by a cassowary on 6 April 1926. 16-year-old Phillip McClean and his brother, aged 13, came across a cassowary on their property and decided to try to kill it by striking it with clubs. The bird kicked the younger boy, who fell and ran away as his older brother struck the bird. The older McClean then tripped and fell to the ground. While he was on the ground the cassowary kicked him in the neck, opening a 1.25 cm (0.49 in) wound which may have severed his jugular vein. The boy died of his injuries shortly afterwards.

The Most Costly Joke in History

Mordhaus says...

https://en.wikipedia.org/wiki/Dogfight

Dogfighting first appeared during World War I, shortly after the invention of the airplane. Until at least 1992, it was a component in every major war, despite beliefs after World War II that increasingly greater speeds and longer range weapons would make dogfighting obsolete.

In the Gulf War of 1990–91, dogfighting once again proved its usefulness when the Coalition Air Force had to face off against the Iraqi Air Force, which at the time was the fifth largest in the world. Many dogfights occurred during the short conflict, often involving many planes. By the end of January, 1991, the term "furball" became a popular word to describe the hectic situation of many dogfights, occurring at the same time within the same relatively small airspace. Oh, fun fact, most of those planes 'dogfighting' in that 'relatively small airspace' were F15's...

But you can ignore that if you want. I mean, ACM schools that teach dogfighting even today probably don't exist...

I linked earlier the marine test that certified the F35 even though it failed the test pretty much completely. http://foxtrotalpha.jalopnik.com/not-a-big-suprise-the-marines-f-35-operational-test-wa-1730583428

Dog fighting does not exist, and has not existed since WW1.

Even in WW2, planes attacked in passes. They start up high, fly down to pick up speed, attack and keep flying so that the enemy cannot catch them.

As that is happening, another pair of planes is already on it's way to make another pass.

Planes do not chase each other dodging around like X-wings and Tie Fighters. Because as soon as you do that their wingman shoots you down.

TopGun trains pilots in BFM and team work skills, not so much dog fighting. While one v one dog-fighting is part of learning good team work skills and becoming familiar with different scenarios, it isn't the focus.

In Vietnam, the missiles and radars were unreliable and missile had to be fired from a fairly close range. That hasn't been the case for some 30 years now, with missiles getting better all of the time with some insane ranges upwards of 80 miles. The plane is becoming more of a launch platform for missiles than anything else. That's why every fighter plane after the F-4 was designed that way primarily. The worlds best fighter is still the F-15 which has a massive radar and the best missiles. And less maneuverability than the F-16. Because they know dog fighting does not happen.



The scenario you mentioned where the planes are flying close together is not realistic - close in air to air combat is 100 miles.

Especially if the enemy plane has better maneuverability(which all Russian planes do already do anyway, apart from the F-16 if lightly loaded).
Pilots know very well the strengths of their planes, they would never put them in a position like that. They would be pinging each other to make their presence known (if a show of force was the desired effect) from over 100 miles away.


None of this makes the F-35 a good plane by any means. But I just don't agree with the reasoning in the comments here and in the media.

For example people keep mentioning the "Jack of all trades" issue. But they ignore the fact that ALL fighter planes built over the last 40 years have been turned into jack of all trades through necessity. Yet nobody criticizes them for it.

I mostly fly the same simulators as the US national guard does. So I'm hoping that it's accurate. But more than that I read a lot of books written by pilots about air to air and air to ground engagements. Which makes me more knowledgeable than 99.99% of the journalists reporting on the F-35. You'll notice that most aviation specific sites don't tend to bag out the F-35 because have a much better idea of how air combat works than the regular media sites.

EDIT: I was not aware they were ignoring failed tests. That's pretty worrying. Do you have more info on it I can read about?
