Ukraine has started some offensive operation in Kursk. Some people are puzzled as for the reason, my guess is that they attack where the defence is weaker.
[...]
If you really want to minimise casualties you would close the airspace, but it is evident that it is not a priority to minimise anything.
But we all know that is not going to happen so again:
To all, please check carefully that you flight does not go over Ruzzia or for that matter Georgia, you may be killed by the Ruzzian air defences.
[...]
Again it's one thing to say that RU should close all of its airspace to minimize unintended casualties to civilian airspace, and completely different story to say "it is
much better to keep it open, it makes drones more difficult to identify" and "keep on trying to find out if it is a drone or a passenger plane" your intentions are crystal clear here.
Ruzzia does not seem to be able to tell the difference between a drone and a commercial plane. From the Ukrainian perspective that is an advantage, as Ruzzia needs to think twice before pressing the trigger which makes their air defence less effective. This is not a moral judgement, it is a fact.
Unless you are saying that Ruzzia is not going to think twice anyway? That the Ruzzian goverment is fine with hitting passenger planes and killing people as acceptable casualties so that their efficiency is not diminished? Because that is exactly what you imply.
Back to serious discussion, Ruzzia seems to be attacking with less and less mechanised means, sometimes to a ridiculous point of sending people on foot or - I have seen a video - riding scooters. There is something happening and it is not looking good for the Ruzzian army.
Exploiting civilian lives for military purpose is a war crime, it is a fact, regardless of how advantageous that might be to any side. Specifically, violation of international humanitarian law (IHL) principles of distinction. I.E. military cannot hide between civilians to confuse the enemy. So it'd be great if you could at least stop encouraging war crimes, or is it too much to ask?
I mentioned it earlier, but paxmao obviously could not calculate it, so here it is:
The energy of a 36-tonne mass hitting the ground at Mach 10 is approximately:
211.8 billion joules (211.8 × 10⁹ J),
Equivalent to 50.6 tonnes of TNT.
The addition of high explosives would seem to be a technical challenge due to re-entry protection issues, and less important than mass itself in transferring energy to a target. The explosive energy would also possibly interfere and cancel out to a degree the kinetic energy delivery characteristics. A simple tungsten rod would probably work best as well as being the easiest thing to do.
Seems that hypersonics would be primarily a digging tool useful in deeply fracturing material. Having multiple attacks mixing in high precision devices which have a heaving effect (cleaning rubble out of the hole) could possibly be a method by which one could dig down to the guts of almost any bunker system. Not to mention causing probably fatal effects on any humans trying to live underground in the area due simply to the shock effects.
Yeah i wonder why Russia would open up it's hand and show it's secret weapon that is capable to dig into earth at Mach 10
must be an unsolvable mystery.
Now, moving on to completely not related news at all:
Ukraine’s gas storage helps Europe avert further energy crises
War-torn country’s tanks enable continent to keep its own facilities close to capacity
...
They had turned to Ukraine, home to Europe’s largest tanks, to store their reserves earlier this year despite the war in the country following Russia’s full-scale invasion of 2022.
...
“Ukraine is playing a key role for central and eastern Europe’s security of gas supply this winter,” said Natasha Fielding, head of European gas pricing at Argus Media, a price reporting agency.
Calling on gas stored in Ukraine “helps Europe to keep its domestic stockpiles high, reducing the risk of sites nearly emptying over any sustained cold in late winter”, she said.
Ukraine has more gas storage capacity than any country in the EU, a legacy of its role as a critical transit country for Russian pipeline gas, which accounted for nearly 40 per cent of the EU’s gas supplies before the invasion.
...
Ukraine emerged as an alternative for holding gas destined for neighbouring states as storage sites in the EU reached near maximum capacity as early as mid-October.
The country also offered incentives such as cheap storage tariffs and custom duty exemptions for three years, allowing gas to be easily reimported to the EU as Kyiv seeks to further integrate itself into the bloc’s energy market.
...
Most tanks in the country sit deep underground in western Ukraine, far from the front lines, and Kyiv has offered up to 10bn cubic metres, a third of national capacity, to foreign customers. That adds to the 115 bcm of existing storage capacity in the EU.
...
Companies began taking gas out of Ukrainian storage in early November, with net withdrawals averaging around 10.7mn cubic metres per day, according to Argus Media. That pace accelerated amid a cold snap in December, with net drawdowns nearly doubling to an average of 26 mcm daily until mid-December.
...
Withdrawals from Ukrainian storage were “definitely helping keep European storage around the 90 per cent region”, said Nikoline Bromander, senior analyst at Rystad Energy.
Keeping these levels high during the winter months is important because it affects the level of difficulty the EU would face in refilling storage during summer, ahead of the following winter.
...
Rystad forecast that barring major supply disruptions, and if demand continues at current subdued levels, the EU will be left with 80 bcm of gas in storage at the end of March, or about 70 per cent capacity.
“Europe is in a quite healthy position,” Bromander said.
Gas storage and transition were off limits while gas flowed through Ukraine, now Ukraine decided to change the rules, good thing those storage facilities are deep under ground and cannot be easily blown up by some drone
