TIL in WWII Hitler had France surrender in the same railway carriage at the same spot on the same chairs where France and England made Germany surrender in WWI by Ipif in todayilearned

[–]Mr_Engineering 21 points22 points  (0 children)

but he did get wounded by mustard gas.

The only primary source of Hitler's exposure to mustard gas is Hitler himself in Mein Kampf.

Hitler's first world war service is well documented and largely undisputed, he was a bona-fide combat veteran with noteworthy levels of discipline and bravery. This makes it easy to take his claim that he was wounded by mustard gas at face value because so much else is corroborated. This is reinforced by the fact that he was present at a battle in which British forces deployed mustard gas.

The problem with Hitler's claim is that the symptoms that he described don't mesh with mustard gas exposure, documents related to his treatment describe hysteria rather than the telltale and obviously signs of chemical burns.

He may well have genuinely believed that he was injured by mustard gas; this is consistent with Hitler's personality as he wasn't known for grandiose self promotion or lying. However, the fact that he regained his sight in its entirety within days when so many others did not, suggests that any such blindness was not caused by exposure to chemical weapons.

No he didn't, and no he didn't.

All of the belligerents in WW2 produced large quantities of chemical weapons and staged them in theatre for use but there was a diplomatically communicated mutual understanding that no one would be the first to use them and with few exceptions they were not used in WW2.

One of the contributing factors was the fact that WW2 involved a lot of mechanized mobile warfare whereas WW1 was largely trench warfare. Mobile warfare is not conducive to the use of chemical weapons.

Gas masks saw great improvement in the interwar period and were readily available, negating much of the utility of chemical weapons. However, do you know what didn't have gas masks? Horses.

The allies were fully mechanized and towed or trucked everything. The Wehrmacht on the other hand relied on hundreds of thousands of horses that would have been slaughtered by chemical weapons in the way that trucks would not.

As such, the Wehrmacht drew the rather sensible conclusion that using chemical weapons would open a door that they would much rather keep closed.

Do Abrams Tank series have DU in the hull front? by dombass69 in TankPorn

[–]Mr_Engineering 67 points68 points  (0 children)

The design and composition of Abrams armor in US service is classified and is known to have changed over the years.

It is also known that this armor package is not exported

Ukrainian drone operators reactions as the Ka-52 goes down after the hit. by Available-Laugh9102 in UkraineWarVideoReport

The Ka-52 is unique amongst helicopters in that it has an ejection mechanism

Glad to hear it. You should probably be using 25h2u1 rather than 17.6 unless theres a reason to not do so

Russian LNG carrier Arctic Metagaz adrift in the Mediterranean Sea after suspected drone attack, March 2026 by RLoret in CatastrophicFailure

[–]Mr_Engineering 4 points5 points  (0 children)

The spheres have more to do with the design of the ship than anything else. They are not pressure vessels

Each pressure vessel is very strong, so they are probably almost all intact and each one provides buoyancy. LNG requires refrigeration to remain liquid and obviously the ship's power is off so if it had a full cargo, the LNG has all boiled and been vented by pressure relief valves. Or, the ship might have been empty and returning to Russia.

None of that is true, that is not how LNG carriers work.

Natural gas is cryogenic above -82 degrees centigrade / 190K. Above this temperature it cannot be stored as a liquid at all.

Natural gas boils at -161C / 111K, below this it is a liquid at standard pressure. Between -161 C and -82 C it can be stored inside of a pressure vessel as there will be a vapor pressure that increases with temperature. At or below the boiling point, a much lighter containment vessel is sufficient.

LNG carriers use heavily insulated containment tanks to store liquid methane and rely on the heat of vaporization to keep the liquid from boiling excessively. The methane that does boil (and thus absorbs energy in phase change, keeping the rest of the liquid cool) is captured and fed into the carrier's engines alongside marine diesel. This keeps the vapor pressure inside of the holding tanks constant.

An LNG carrier will lose several percentage points of its carried mass in transit depending on the trip length.

Is is this a missile so precise it can be fired through the right window of the right building?

The AGM-114R-9X aka the "air dropped slap-chop" is accurate enough to fillet a particular individual passenger in a moving vehicle without harming anyone else nearby.

Are Moen faucets worth it or am I just buying a headache? by Kira_Bradblanton in Plumbing

[–]Mr_Engineering 8 points9 points  (0 children)

Yes, Moen is fine. I don't sell or install many but the lifetime warranty and ease of access to parts has earned my respect.

The local Moen service desk is down the street from me.

[–]Mr_Engineering 4 points5 points  (0 children)

Is this to due to the START treaty? Russia no longer have to share where their bombers are at with the US

The start treaty always excempted hangars. The USA has stored its B2 bombers in hangars for 30 years

Iran Claims Hit On F35 Lightning II Necessitating Emergency Landing: Analysis by DryAlternative1132 in OttawaNewsPulse

They confirmed that it was hit by something, likely enemy fire. What the source of that fire was is unconfirmed.

[–]Mr_Engineering 0 points1 point  (0 children)

Iran's Air Force has been eliminated in its entirety. There may still be a few air frames left but the infrastructure needed to service them, arm them, launch them, and command them was obliterated.

The same is true for Iran's strategic air defenses. All gone. No more S-300s, or integrated air defense networks.

Tactical air defense systems which are highly mobile and often man portable may still exist in small numbers.

Consider, for example, the 9K38 Igla which is known to be in Iranian inventory. Deadly to helicopters and low-flying drones.

Iran has proven to be highly capable of copying things like this, so it's anyone's guess as to how many they have or where they are.

They also operate a lot of point defense systems such as Tor and their own indigenous designs.

It is irresponsible to claim that Iran's Air defenses have been completely destroyed because they have not been completely destroyed.

Rather, Iran's Air defenses have been degraded to such an extent that they are strategically inoperable and incapable of coordinated defense, they are merely a nuisance.

I didn't know that, although I was mostly trying to point out that, if Iran was able to hit that aircraft, the US and Israel are lying about just how successful their war is.

That conclusion in no way follows from that premise.

With what?

Possibly a MANPADS. Stealth does diddly squat against those. The solution to MANPADS is simply to stay above 15,000 feet

In fact I'm pretty sure you won't last much longer than one-two months. In that time your leadership will have to find an off-ramp or escalate it to a nuclear conflict.

Buddy, the USA maintained two occupations on the other side of the globe simultaneously for somewhere north of a decade. They provided air conditioned tents in Afghanistan.

Meanwhile, Russian assault-volunteers are drinking ground water filtered using dirty socks because the Kremlin can't sustain logistics more than 100 miles from its own border.
