@Kirwan how do you harden a drone? Genuine question - I see drones as massive, but also not yet having drone defences going
Hardened against jamming. It's a new arms race.
And I'm not talking about defence against a handful of drones, think about the displays you see with thousands of drones all perfectly making patterns.
Now imagine each with a grenade doing kamikake raids with tens of thousands of them flying into the battlefield costing $50 each. Modern warefare is going to suck.
do they go slow enough that computer controlled guns could hit them - like missile defences?

When's Musk's green hydrogen car coming. Possible game changer for all.
Well Musk calls Fuel Cells "Fool Cells", so not very likely.
Once Tesla moves into tanks that might change...
Hyundai unveils world’s first hydrogen-powered, silent stealth battle tank
The K3 will be powered by hydrogen fuel cells and feature other advanced tech to become one of the world's most sophisticated tanks.
Surely that's an April Fool's joke? Who'd want to be near a pressurised hydrogen cell someone else is shooting at?
If they blow up they blow up.
Anyway it looks like the initial model is diesel.
But imagine that, an "environmentally responsible" tank! What could possibly go wrong!!
How Hyundai's Hydrogen K3 Tank is Redefining Military Stealth
The Hydrogen K3 tank is a marvel of engineering, utilizing hydrogen fuel cell technology to ensure near-silent operation. This feature alone offers a

How many countries have done this?
Civil Aircraft Breaks Sound Barrier for First Time Since Concorde
Dawn Aerospace’s Mk-II Aurora becomes the first civil model in decades to fly faster than the speed of sound.

Based on the information provided in the search results, multiple countries have developed supersonic aircraft over the years. Here’s a breakdown of the countries that have built supersonic planes:
Countries with Supersonic Aircraft Development
1. United States
2. United Kingdom
3. France
4. Russia (formerly Soviet Union)
5. China
6. Italy
7. Taiwan
8. South Africa
9. Canada
10. Pakistan (in collaboration with China)
11. India
12. Egypt
13. Iran
14. Israel
15. Republic of Korea (South Korea)
It’s worth noting that some of these supersonic aircraft were developed through international collaborations. For example:
• The Concorde was a joint project between the United Kingdom and France.
• The CAC/PAC JF-17 Thunder was developed through a collaboration between Pakistan and China.
• The Eurofighter Typhoon is a multi-national project involving several European countries.
Additionally, New Zealand has recently entered the supersonic aircraft arena with the successful test flight of the Mk-II Aurora, developed by Dawn Aerospace.
While this list includes 15 countries plus New Zealand, it’s important to note that not all of these countries have produced operational supersonic aircraft in large numbers. Some have only developed prototypes or experimental aircraft, while others have established long-standing production of various supersonic models. -
A mix by the looks of it;
In summary, there are at least 5 crewed supersonic aircraft mentioned, 2 unmanned supersonic aircraft, and 2 additional aircraft whose supersonic capabilities are unclear based on the provided information. It’s important to note that some of these aircraft are still in development or are prototypes, while others are historical research vehicles.

Incredible.
Amazing how fast this becomes 'routine' - oh yeah, 33 engines going for it, no failures ... just normal
They've pretty much nailed landing control of both the booster and starship.
They must update the main code database and then the physics geniuses go to work on tweaking it. It's relentless and so impressive. -
@BerniesCorner strong recommend for both books on SpaceX by Eric Berger. Reading the second at the moment, they are both fascinating insights into the business.
