Russian soldiers training with T-62. If Russia really has thousands T-72 in working condition then T-62 use would be pointless... logical conclusion is that Russian tank T-72 & T-80 reserves aren't as large as claimed.

I remember when back in 2015 Russia fanboys were telling me that by 2020 Russian army will have at least 1000 T-14 Armata tanks but in 2022 Russian military is fielding tanks from early 1960's.

Actually what Russians call "reserve" are just large open garbage fields where heavy equipments are such in a poor state after decades of negligeance,corruption,theft only God knows how many of them can be put back into action.

But remember Russia isn't sending its real army into Ukraine,the real army is in Russia waiting for NATO and remember Russia can steamroll Europe in 48 hours.

1st peace offer in Istanbul ended in failure, after Boris Johnson rushed to Kiev and ordered UA President Zelensky not to sign it. .... since you don't sign an agreement based on agression!

2nd peace offer now comes with much worse terms for Ukraine. .... since Russia slowly accepts it cannot win this war and tries all its best to gain as much!

3rd peace offer in 2023 will be catastrophic. ... for Russia, since its collapses as a functioning state!

I think Russia's goal is to have Ukraine surrender Crimea and Donbas.

Intercepting low flying high speed rockets is a thousand times harder than shooting down your own civilian airliner. Iron Dome intercepted rockets bigger and faster than HIMARS like M302. Also intercepted drones.

Iron Dome is purchased by the US to defend Guam against drones and cruise missiles, also purchased by Azerbaijan, Cyprus, Romania, and many other are looking to buy it.

I have seen iron dumb action only against Hamas sugar and pipe rockets.
Any more real war example?

UAV is an Austrian invention from 1900s.

UCAV first documented real use: Iran

First drone with air to air combat use: Iran

First anti-aircraft loitering drone: Iran

Let us revisit this story...

www.theregister.com

Chinese distributors reportedly dump dud chips on Russia

What? Sanctions-busting sellers aren't interested in your complaints? That's a shame
www.theregister.com www.theregister.com

China has a captive market -- Russia. And Russia, despite the plethora of electronics products in the world, is unable to access any of them. This story illustrate perfectly your example. If there is a single source of DDR5, then Apple and everyone else would paying a premium price no matter the per wafer yield. But there are many sources of DDR5, even if one source maybe slightly behind in tech node than competitors, the availability of many sources drives prices down, and any company whose DDR5 wafers have less than %50 yield will be rejected.

Most customers are not aware of the yield and only buy packaged chips which they expect will meet the specification.
You claim that those with lower yield will be sold at a lower price than those products with a high yield.
Why would anyone reject the lower priced product over the higher price product when both are sold based on the same specification?

The reality is that the high yield vendor with 100 chips need to charge the wafer processing cost / 100 per chip to break even, and the low yielding vendor with 10 chips per wafer need to charge wafer processing cost / 10 to break even.

They need to charge 10x more due to the low yield.

Because customers do not want them, simple as that. What I presented are very relevant, not just to everyone but to the China-Russia relationship.

As a buyer, I do not care how much you want to recoup your failure rate. If there are alternatives to you, that is an edge in my favor, not yours. If your wafer have a %50 yield, that is suspicious to me. If your wafer is in the new tech node, then we can negotiate, but if your wafer is of established tech nodes same as your competitors, why should I take a chance on yours?

Look at this paragraph in that story...

Even a two percent defect rate is sub-optimal, because products made of many components can therefore experience considerable quality problems. Forty percent failure rates mean supplies are perilously close to being unfit for purpose.​

A %40 failure rate mean ALL the dies on that wafer is suspicious. It mean I do not know what I would be buying from you. A die may pass your tests but could fail mine, a %2 risk I am willing to accept, but not %40. That is what the Russian electronic products manufacturers are telling the world of Chinese semicon sold to Russia. Simplistically speaking, we can say that out of 100 washing machines, each of them have a %40 chance of failure to run. Out of 100 cars, each of them have a %40 chance of getting the Russian equivalent of the 'Check Engine' light. The average Russian would not know until he paid for his stuff.

This story perfectly illustrate the danger of having the world's semicon products so concentrated in Asia. When JPN experienced earthquakes, semicon markets reacted on the next day by raising prices. If China gain control of the SCS, the world would be similar to what Russia is going thru now.

M302 are Iranian made rockets, copies of Chinese rockets, weighing 500kg. Intercepted by Iron Dome. Also intercepted Hezbollah and Hamas drones.
In tests it intercepted cruise missiles.

You call UCAV a drone with RPG7s attached to it lmfao, first UAV usage was done by Israel in 1973.

First air to air usage of drones was done in 1990 in Iraq when MQ1s were firing stingers at enemies.

last one is just wrong

the problem here is the failure was 2% , then after sanctions against russia it become 40% and Russia don't buy wafers , it buy chips.
If you buy wafers you get lower price , but there is no guaranty if the chips work or not. when you buy chips , the faulty chips is the responsibility of the producer , they must test the chips and give you working chips .

the only answer is that Russia seems dont buy the chips from manufacturer , they buy it from black markets , there there is no guarantee , the chance you get a faulty chip is even higher than when you buy the wafer.

Hey, we agree on something ! ! !
