> There is a similar problem with drone pilots -- it took Ukraine and Russia years to scale up and get to the current level of skill. However, training drone controllers is cheaper because the aircraft cost nothing.

Unlikely that pilots would work for drones in a fight with China over the pacific, the jamming and electronic warfare environment would make remote piloting nearly impossible, which is why CCA efforts are looking at onboard AI piloted aircraft. Even in Ukraine the EW environment is so harsh that FPV drones have resorted to using physical fiber optic cable connections so the drones cant be jammed out of the sky.

Any sort of drone that has the range, speed(shaheds only go ~180 km/h), and survivability to last in or near Chinese airspace is going to be expensive and complicated.

The pacific theater is a way different combat environment then Ukraine. The ranges involved and china's IADS is just a whole different beast. The cheap drones that we have been seeing in Ukraine and Iran are just not as useful in a war against china. Cheap drones don't have the range or survivability to penetrate china's airspace or hit moving targets(most go to fixed gps coordinates), this is a job for stand off munitions and manned stealth aircraft. There's no current UAV or CCA that exists that has the capabilities needed to replace manned aircraft for the majority of missions that would need to be flown. Wargaming shows that the b21 and f47 as well as stand off munitions are the workhorses. Although something like a Barracuda-500 seems very interesting but again its like 10x the cost of the drones being used in the Ukraine theater and its production lines are just now being set up.

It says right in the article ~200 a year. The base scenario in recent war games, the US lost 270 aircraft total, of which 206 were USAF. Japan lost 112, Taiwan's air force effectively ceased to exist. Across iterations, Air Force losses ranged from 168 to 372(mostly on the ground)in a fight with China over Taiwan. Those are substantial losses but assuming all the losses were f35(they were not) even at current non wartime production rates the United States could replace that in a few years time.

Also the war games showed that when LRASM supplies were depleted, the f35 became the primary anti ship and strike asset as it was one of the few aircraft that could fulfill the role and survive.

> "At over eighty million dollars per airframe, with Lockheed Martin delivering fewer than two hundred aircraft per year across all variants and all customers worldwide, there is no surge capacity waiting to be activated and no precedent for accelerating a program of this complexity on wartime timelines. When one side can produce weapons by the hundreds and thousands — missiles, loitering munitions, and one-way attack drones — while the other relies on small numbers of exquisite platforms, the advantage shifts toward the side with scale."

The article gets this wrong as well, the f35 can be built at scale, no other fighter aircraft is produced in such high numbers, its also significantly cheaper on a per airframe basis vs Gen 4 aircraft and its more advanced. This article is nonsense and the author doesn't know what they are talking about.

I assume in this case they already had a bunch of firewall rules for PF and switching from OpenBSD -> FreeBSD is a much easier lift then going to linux because both the BSDs are using PF, although IIRC there are some differences between both implementations.

Agreed, its one of the many reasons I cant wait for the shift from ICE vehicles to EVs, they are just so much quieter.

Umm each plane cost way less than 1.7 Billion. A F35A can be purchased for around $80 million. The 1.7 trillion figure is the cost of research & development, purchasing about 1700 aircraft, and sustaining them for 57 years. So that includes fuel, spare parts, upgrades, pilots, etc, for almost 60 years.

For a military, non WW2 plane, 1000 aircraft is a lot. The US government plans on buying around ~1700 F35 and US allies have orders for another ~1000 F35. Overtime I would expect the number of orders for f35 to keep going up.

Have you been to a Fred Myers recently? It's amazing how much stuff in the meat and dairy sections are not available anymore.

Public health officials should tread carefully otherwise they risk alienating large segments of the population. Which would inturn be bad for public health.

I love my 2017 Ford Focus RS! It has a touch screen but besides for that there's no lane assist, automatic breaking, or any other driver assists. I also love that it is a manual, however some people may not like that. Also they only made it from 2016 - 2018 and used ones are expensive. But check it out if you want a modern, fast, manual car with minimal digital none sense.

I guess it depends on where you work. I have "unlimited pto" and over the last 5 years I've taken at least a month a year.

So you want country wide restrictions solely for your own comfort? Sounds incredibly selfish.

Your health Minister seems to be spreading misinformation.
