Hypersonic Missile Nonproliferation

scheherazade says...

The Zero's Chinese performance was ignored by the U.S. command prior to pearl harbor, dismissed as exaggeration. That's actually the crux of my point.

Exceptional moments do not change the rule.
Yes on occasion a wildcat would get swiss cheesed and not go down, but 99% of the time when swiss cheesed they went down.
Yes, there were wildcat aces that did fairly well (and Zero aces that did even better), but 99% of wildcat pilots were just trying to not get mauled.

Hellcat didn't enter combat till mid 1943, and it is the correction to the mistake. The F6F should have been the front line fighter at the start of the war... and could have been made sooner had Japanese tech not been ignored/dismissed as exaggeration.


Russian quantity as quality? At the start they were shot down at a higher ratio than the manufacturing counter ratio (by a lot). It was a white wash in favor of the Germans.
It took improvements in Russian tech to turn the tide in the air. Lend-lease only constituted about 10% of their air force at the peak. Russia had to improve their own forces, so they did. By the end, planes like the yak3 were par with the best.


The Mig31 is a slower Mig25 with a digital radar. Their version of the F14, not really ahead of the times, par maybe.

F15 is faster than either mig29 or Su27 (roughly Mig31 speed).
F16/F18, at altitude, are moderately slower, but a wash at sea level.

Why would they shoot and run?
We have awacs, we would know they are coming, so the only chance to shoot would be at max range. Max range shots are throw-away shots, they basically won't hit unless the target is unaware, which it won't be unaware because of the RWR. Just a slight turn and the missile can't follow after tens of miles of coasting and losing energy.


Chinese railgun is in sea trials, right now. Not some lab test. It wouldn't be on a ship without first having the gun proven, the mount proven, the fire control proven, stationary testing completed, etc.
2025 is the estimate for fleet wide usage.
Try finding a picture of a U.S. railgun aboard a U.S. ship.


Why would a laser rifle not work, when you can buy crap like this : https://www.youtube.com/watch?v=7baI2Nyi5rI
There's ones made in China, too : https://www.sanwulasers.com/customurl.aspx?type=Product&key=7wblue&shop=
That will light paper on fire ~instantly, and it's just a pitiful hand held laser pointer.
An actual weapon would be orders of magnitude stronger than a handheld toy.
It's an excellent covert operations weapon, silently blinding and starting fires form kilometers away.


Russia does not need to sink a U.S. carrier for no reason.
And the U.S. has no interest in giving Russia proper a need to defend from a U.S. carrier. For the very reasons you mentioned.


What Russia can do is proliferate such a missile, and effectively deprecate the U.S. carrier group as a military unit.

We need carriers to get our air force to wherever we need it to be.
If everyone had these missiles, we would have no way to deliver our air force by naval means.

Russia has land access to Europe, Asia, Africa. They can send planes to anywhere they need to go, from land bases. Russia doesn't /need/ a navy.

Most of the planet does not have a navy worth sinking. It's just us. This is the kind of weapon that disproportionately affects us.

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.

Hypersonic Missile Nonproliferation

Mordhaus jokingly says...



Also, the Japanese planes sacrificed durability for speed, maneuverability, and gun capability. Once US pilots realized this, they exploited the vulnerability because our planes were basically tanks compared to the Japanese ones.

The US had the best rocket program once the Saturn V became available in the 60s.

As of 2018, the Saturn V remains the tallest, heaviest, and most powerful (highest total impulse) rocket ever brought to operational status, and holds records for the heaviest payload launched and largest payload capacity to low Earth orbit (LEO) of 140,000 kg (310,000 lb), which included the third stage and unburned propellant needed to send the Apollo Command/Service Module and Lunar Module to the Moon.[5][6]

The largest production model of the Saturn family of rockets, the Saturn V was designed under the direction of Wernher von Braun and Arthur Rudolph at the Marshall Space Flight Center in Huntsville, Alabama, with Boeing, North American Aviation, Douglas Aircraft Company, and IBM as the lead contractors.

To date, the Saturn V remains the only launch vehicle to carry humans beyond low Earth orbit.

Hubris.

WW2 japan had fighters that flew faster, climbed quicker, had bigger guns, and turned quicker (a6m vs f4f). And we had intel reports that told us, but we ignored them because "we have the best stuff and nobody else can compete".

You see the same stuff today with China. China makes all of our microchips, all of our microelectronics, most of which are designed over there anyways (companies here just ask for a widget that does X and Y, and Chinese companies design+make it), yet we act like as if they are some technologically retarded place that only knows how to steal ip.

Russia has been at the forefront of rocketry since ww2. Nobody has systems that compare to their consistency and reliability. Not even the U.S.. The idea that Russia can't make a hyper sonic missile before the U.S., because it's Russia, is a non sequitur.

Also, Russia broke up as a country because guaranteed government jobs for all citizens, where you can't be fired and performance is not important, is going to destroy any economy. No one will produce, shelves will be empty, and money will be no more than paper. Combine that with making private business illegal (preventing people from economically helping themselves), and you have a recipe for economic disaster and social discontent.

This missile exists to swat down carrier groups on the cheap.
We're gonna need some powerful lasers, or our own hyper sonic interceptors, or else proliferation would instantly leave us isolated in the Americas (vis-a-vis power projection via conventional weaponry). Our only option for projecting power would be reduced to nuclear or nothing.

A Scary Time

BSR says...

Thanks for your reply bcglorf,

To clear up my analogy, I was actually speaking about the power, tolerance and bravery of women and the thick headedness and cowardice of men who are abusers.

Sometimes you need to find a language that can be understood.

I also think reasonable people believe that any action taken against them should be met with equal and opposite reaction.

Somewhere I posted a quote from the movie Tora, Tora, Tora, which I altered to fit the present conversations.

The quote was said to have been made by Japanese Admiral Isoroku Yamamoto regarding the 1941 attack on Pearl Harbor.

It's debated if he actually said it but it was something that I remembered and thought it fit well with recent events with the altered quote.

My altered quote is:

I fear all we have done is to awaken a sleeping giantess and fill her with a terrible resolve.


Women (giantess) are coming together, along with men, more than ever before and rightly so.

I never said or implied anything about ridicule or attacks.

Thanks again for your reply and I think we both are on the same side.

bcglorf said:

Not sure that's the analogy you want to go for, what with the counter being to describe how we behave once we grow up...

You are describing women as powerless and perpetual victims, which I think is offensive to women. You then basically say that two wrongs make a right because victims should be allowed to create new victims if it helps them...

Reasonable people disagree with you. If that puts me in the 'wrong' camp, and means I deserve ridicule and attack, you're the problem, not me.

Look, this is basically Japanese "jackass". It's a bunch of idiots hurting themselves for our (and their) amusement. The gender doesn't matter.

visionep said:

Well, I guess we can flip it around then and see if it's still funny.

Imagine the same situation with a skinny young adult woman sitting there with her legs spread open. Nervously laughing and obviously doesn't want to be violated by the screwlike device. But she stays there because this is her job and allows the activity to complete until it is too painful and she jumps up and runs away while everyone is laughing.

Hmm.. not funny, even if they are being paid for it. Financial coercion to do these types of degrading acts isn't right but it's probably legal. So I guess you can legally laugh.

The Day Liberty Died

bcglorf says...

And then we can largely agree. Can we agree even further though that listing only one combatants crimes can become misleading?

America dropped nuclear weapons on Hiroshima and Nagasaki, killing hundreds of thousands of civilians.

Prior to that they fire bombed virtually every other Japanese city, killing 100 thousand in Tokyo alone.

The fighting on the ground on the islands reads like one long list of horrific war crimes against dehumanized Japanese victims again and again...

I know the illustration shouldn't be necessary, but presenting a single sided selection of choice facts can be extremely misleading, and the video here, like many on Israel today, does exactly the same thing.

newtboy said:

Yes. Distrust of one untrustworthy nation doesn't translate into trust of their untrustworthy enemies.

International distress frequencies jammed. That's war crime #1. Firing on lifeboats, war crime #2.
You can convince yourself that their unambiguous identification of it as an American ship before attacking is meaningless, you still can't excuse the multiple war crimes.
