A look at an interesting Ukrainian drone. It has a 4-cylinder engine but is otherwise a bit of a mystery.

Where do the engines come from? That is the question I ask whenever a company announces it is going to make large quantities of long-range drones. Here is a close look at a Ukrainian engine. The article is free to read on Substack. danielrphd.substack.com/p/ukraine-ma...

The Bars cruise missile (sometimes a drone) is one of the more interesting developments to come out of Ukraine. Of course, development does not stop.

This drone flying over Ukraine illustrates how much trouble the world is in. Is it operated by russia or North Korea? Was it made in North Korea or in China? Or was it supplied by Iran? Shaun Pinner and Chris Sampson recently asked, "Are we in a world war?" Perhaps yes.

1. Ukraine has been targeting electrical substations in Crimea and other parts of occupied Ukraine. The NASA Worldview data lets us see the effects on night-time lighting. An image from April 5, 2026 shows where there are lights and thus power.

1. I wrote an article about a Ukrainian drone that for a long time did not have a name. Now it has two names, an interesting engine, and a curious business arrangement. These drones are being made in quantity and have been spotted flying into russia. Here's your chance to see what's inside.

Ukraine has systematically targeted russian air defence, and pretty much everyone (including me) predicted that the situation could rapidly change once these defences were sufficiently degraded. The result is still surprising though. This is like watching baby seals being bludgeoned.

Ukraine continues to hit electrical infrastructure in Crimea. Unfortunately, it was partially cloudy the night of July 5 but obviously russians are struggling to keep the lights on. The city of Yevpatoriya is dark.

1. This is a toy drone that looks disconcertingly like interceptor drones seen in Ukraine. Yes, we are aware that this is a toy and not a weapon - at least not a very good weapon. A larger version with different, but off-the-shelf, electronics would be much more capable.

Let’s talk about Crimea. Because Putin wants you talking about everything else. NATO. Nuclear threats. Belarus. Escalation. Red lines. Anything except the one issue that could become the greatest strategic failure of his entire reign.

While a russian was being chased by a Ukrainian drone, a second drone flys in. Notably, the second drone is controlled using a fibre optic link. There are many such videos showing two drones attacking a single russian soldier with a predictable outcome.

$350 billion is enough money to buy every active F-16 fighter jet and every active M1 Abrams tank with enough money left over to buy every Black Hawk helicopter, several aircraft carriers and some nuclear submarines. However, the USA sent zero F-16 fighter jets and thirty-one M1 tanks to Ukraine.

Listen to the engines on these Ukrainian Liutyi drones and note how slow they are flying. Possibly, speed is being adjusted to maximise the dones' range and payload.

"Iran has just announced" tells us that it is Iran, not the USA, who is controlling events. "Strait of Iran" confirms this. The USA is a bully who kicked a dog only to find out the dog has very sharp teeth. It will be interesting to see what concessions the USA makes.

A Ukrainian FP-2 drone nearly collides with another FP-2 drone while flying over a russian air defence system that was destroyed earlier by a Ukrainian FP-2 drone. Ukraine has been quite successful at destroying russian air defences with these drones.

1. Twenty-three years ago I held a Canon A10 digital camera up to the eyepiece of a cheap 60 mm refracting telescope and pressed the button. This is the photo I captured on that cold winter night. It was far better than I could have ever got using film.

🇨🇦 Fuelled the car today (March 21, 2026). For USA citizens, this price for regular corresponded to US$4.25 per US gallon. These pump prices have no meaningful effect on my life but higher fuel prices will increase the cost of everything else including food.

No, I still can’t get this out of my head, and I keep trying to grasp the full abyss of this idiocy, unsuccessfully. Russia spent years, decades "fighting all of NATO," turning America into "radioactive ash" every night on state TV.

youtube.com/shorts/Z4mu2... Well I was correct, the ballistics attack did materialize last night and the early hours, in an all but predictable attack on power infrastructure. However, it’s not all going Putin’s way, not in the slightest, in fact it’s getting worse.

I had a work colleague who started acting weird like this. Five year later he was dead from frontotemporal dementia. Earlier symptoms included a strange impulsivity where he could not be reasoned with. A later symptom that could not be ignored was his aphasia.
