I know people are going out looking for the drones at these bases in the UK. Quick reminder, without lights on they are very hard to spot, especially from a distance. Counter-UAS (C-UAS) systems primarily rely on passive detection of the radio frequency energy the drones emit (if they emit), but the more advanced suites include radars (often in Ku-band) to spot them even if they are operating without emitting.
These active and passive sensors work together to better detect and classify the object. They also allow for critical intelligence to be collected on them. EO/IR systems are also almost always part of the C-UAS suite so that visual ID can be made. They can also help search and detect drones as well. The radar systems have short range and the passive detection systems can also be limited in range, especially if the drone flies low and amongst ground clutter. This makes it hard to track where they are launched and recovered from without physically tracking them in a vehicle.
A bad actor well versed in these basic capabilities would design their drone operations plan to exploit common C-UAS suite limitations.

On Holodomor Memorial Day, the terrible famine that started in 1932 is remembered.
The Soviets took away bread from the Ukrainian people, and they starved.
Now the Russians want to take away everything.

Grim reading. Its hard to disagree with view that due to entirely self inflicted and easily avoided reasons, other than CASD and carriers, the RN is now a barely 2nd tier NATO navy in terms of numbers and increasingly quality. The decline feels terminal.

A Danish Navy vessel boarded the Chinese cargo vessel Yi Ping after it was discovered it had destroyed 2 undersea telecom cables in the Baltic Sea.
Denmark exercised the right under Art. X of the Submarine Cables Convention. It's been done only once before, by the USA in 1959

I can't remember seeing such a specific warning before, correct me if i'm wrong, despite air attacks with drones and missiles are happening every day in Ukraine

Just discovered PySpecSDR, a Python SDR tool with a scanner function that includes signal classification by analyzing spectral properties (sounds great for WarDragon). Found it after revisiting @rtlsdrblog on Reddit. Check it out: github.com/xqtr/PySpecSDR

Army Arsenal Seeking Info On Mysterious Drone Flights Over Installation

"Internet terror" on a European scale: two underwater cables of EU countries were damaged today.
Namely, in the first case, the underwater cable C-Lion1, which runs from Santahamin (Finland) to Rostock (Germany), was broken. Its length is about 1200 kilometers.
The second case of damage to the communication cable was between Lithuania and Sweden. As a result, Telia, which transmits Internet connections to Lithuania through three cables, lost a third of its Internet bandwidth.
❗️In particular, The Gurdian reports that a russian reconnaissance ship, the Yantar, was spotted operating drones in an area with underwater energy and internet infrastructure.

Russia is now severing the internet cables on which the US and Europe rely for global communications, two in one day.
Probably no coincidence that Musk has the "solution" via his starlink.
Naive western folks still has no idea what's coming.

Today, together with the Prime Minister of Denmark, Mette Frederiksen, we met with Ukrainian manufacturers of long-range drones and the warriors who operate them.
We inspected Ukrainian drones procured with Denmark’s support and according to the Danish model—funds are allocated to contracts already concluded by the state-owned enterprise with manufacturers.
Denmark is a friend we can truly rely on. Together, we are defending the lives of Ukrainians. Together, we are producing weapons for Ukraine. And together, we are working on recovery from the destruction caused by this war.
🇺🇦 🇩🇰
