🇺🇸The US could face catastrophic defeat by China or Russia in a hypersonic Third World War.

How much do you know about the hypersonic arms race? ⬇️
telegraph.co.uk/world-news/202…
⏩Hypersonic means travelling faster than the speed of sound, meaning there would be little time to react…

But, by at least how many times faster?
It's five!

🔊 Hypersonic means travelling above Mach 5, or five times the speed of sound
⏩Unlike a ballistic missile Hypersonic Glide Vehicles are extremely manoeuvrable, allowing them to evade tracking and defences
🇨🇳China's DF-17 hypersonic missile can travel at 10 times the speed of sound (Mach 10) and carry a nuclear warhead
🇷🇺 But the Kremlin's pride and joy, the Avangard hypersonic missile, has reached a staggering Mach 27

❓How far did the Avangard missile travel when it was tested in December 2018?
It's 4000 miles.

🏙️ The missile can also carry a two-megaton nuclear warhead, enough to wipe out a city

🇺🇸It's fair to say there is some paranoia at the Pentagon about America's current predicament.

The US is now pouring money into hypersonic development in a bid to keep up…

❓But just how much?
💸It's $1 billion a year

The US expects to have its own hypersonic weapons in the 2020s, and hypersonic drones in the 2030s
🛰️In addition, the US is prioritising a huge defensive measure, with a plan to put a a "mega-constellation" of potentially hundreds of satellites into space to monitor hypersonic missiles

Before the Taliban marched into Kabul, police in the capital would sometimes arrest addicts and transfer them to the centre.

⚫️But since the hardline Islamists took control, the frequency of raids on areas where addicts gather appears to have increased.

🔴 Over the weekend, it emerged that the Chinese military in August secretly launched a rocket carrying a hypersonic glide vehicle into space.

It flew around the globe through low-orbit space before returning to Earth
telegraph.co.uk/world-news/202…
🚀While the missile reportedly missed its target by about two dozen miles, the test shows China has made rapid progress on the lightning-fast weapons and is far more advanced than US intelligence officials had realised.

“We have no idea how they did this,” one official said
Drew Thompson, a former American defence department official with responsibility for China, said the test “really should change US calculations”.

“I think it is a game changer in a way that little else has really shifted the balance”

⚫ Millennial mafia members in New York have been accused by veteran mobsters of going soft, @nickallen789 reports.

They’re obsessed with their phones and using text messages rather than fists to intimidate victims

Thread 🧵

The new generation of mafia soldiers are said to be less brutal and less versed in traditional in-person tactics.

➡️One alleged gangster sent his victim, a union official, a message saying: "Hey, this is the 2nd text, there isn't going to be a 3rd"
The extent to which social media has now infiltrated the crime world was evident in the recent case of a fugitive mafia suspect.

His son pictured him in a swimming pool in Florida and taunted the FBI by posting it on Twitter, along with a rat emoji 🐀
