Unconfirmed reports from Iran claim that IRGC have deployed it's entire arsenal of it's flagship icbm Khorramshahr-4 nicknamed Kheybar (referring to historical fighting between Muslim prophet and Jewish tribal opposing him that led to destruction of Khaybar castle by Muslim troops).

The missiles were previously used during the attacks against ISIS targets in Syria (as many claimed to be the test run for attacking targets in Israel).

Kheybar is 13m long and weights 20tons with a massive warhead of 1500kg, can reach the maximum 16mach and supposedly has a mach 8 speed on impact.

No one really knows how many of these missiles are produced and operational.

The #US wants to spend $13 billion to build Arctic #icebreakers, in order to compete with #Russia and #China. Except, the US seems to have "lost" the technology to do so.

"U.S. officials are racing to procure new polar icebreakers because one of only two that the Coast Guard now sails has reached the end of its life, and the one assigned to the Arctic is out of service for maintenance every winter."

"Delivery of the first new icebreaker has slipped to 2028 from 2024 as designers, engineers and welders grapple with something the U.S. hasn’t done in decades: reliably shape hardened steel that is more than an inch thick into a curved, reinforced ship’s hull."

"The Coast Guard hasn’t launched a new heavy icebreaker since 1976. Out of practice, U.S. shipbuilders have had to relearn how to design and build the specialized vessel, say officials in the industry and the government."

"By comparison, Russia has three dozen national icebreakers suitable for the Arctic, according to the U.S. Coast Guard, and China has four, including two icebreaking research ships that regularly appear at high latitudes."

"The machinery and skills to build the hulls of most oceangoing vessels aren’t sufficient for the specialized icebreakers. The hull plates need a bespoke alloy and specialized heat-treatment, with a process to form and weld massive curved plates."

“Higher-strength steels require very skilled people,” said Jeff Moskaluk, senior vice president at SSAB Americas.... “It’s not like you just treat it the same as any other piece of steel. It takes a beating—that’s exactly what the steel is designed for.”

"In addition to the technical challenge, American yards are reckoning with a shortage of shipwrights. Employment in ship and boat building totaled just 154,800 in July after peaking at 1.3 million during World War II, according to data from the Federal Reserve."

'“One of the challenges is the workforce—getting qualified welders,” said Bob Merchent, retired former chief executive of VT Halter Marine, since acquired by Bollinger Shipyards. '

So many people seem to think that because we are the US, we have the best technology in the world, and the most skilled workers.

That used to be true. It hasn't for a long time now, though, and the situation is getting worse, jeopardizing national security in multiple ways.

We don't have the designers or experienced engineers. We don't have the shipwrights or welders. We are having trouble with basic execution, because investment bankers don't understand #technology, and think blue collar workers are interchangeable.

It isn't just our inability to build super-sophisticated #hypersonic #missiles, while Russia and China can.

We can't even build an icebreaker, while "poor, pathetic, backward" Russia has 36 in service.

###Iran defense industries revealed another new long range missiles claiming to by "hypersonic" and "radar evading" with range of 4000km

The missile name Fattah is claimed to have the most advanced rocket system ever built by "Iranian engineers" that make it able to reach speed of Mach 15 during the first phase, Mach 8 after the first stage detached and hard to believe Mach 5 at impact.

They also claim that the missile has ability to evade and change altitude and direction during the operation phase without the need to be connected to a land based control system in order ro prevent detection and interception.

The most important aspect of the missile is that it uses solid fuel instead of liquid in the second stage that gives it #shelf life of minimum 20 years# after production.

During the extravaganza surrounding the release of the information they were having banners like "Jerusalem gate opener" and "Nightmare of Zionist regime"

So far no information about the weight of the unit, nor the weight and capacity of the head of the missile been released, but the design and shape of the head is almost identical to the previously prevailed #Khorramshahr -4 that can hold a payload of 1000kg or up to 80 smaller cluster munitions to target troops in battlefield or industrial targets.

The Physics and Hype of Hypersonic Weapons - Scientific American

Our studies indicate that hypersonic weapons may have advantages in certain scenarios, but by no means do they constitute a revolution. Many of the claims about them are exaggerated or simply false. And yet the widespread perception that hypersonic weapons are a game-changer has increased tensions among the U.S., Russia and China, driving a new arms race and escalating the chances of conflict.

I shared a German translation before. In short, it all comes down to physics!
