Kiev has like 3 million people and Shanghai has 27. The Russians didn't even get to Kiev

It's halfway to an acknowledgement that landing on the Chinese mainland is beyond the capabilities of any branch of the US military, and so there's no mission for the USMC in that sort of war.

Titanium is not in the power turbine, titanium is in the compressors. Power turbine airfoils are single crystal nickel superalloy which is the peak of metals more or less. The future is in ceramic composites to achieve the highest temperatures.

im pretty sure deets on this subject is why the intel community is up to their tits in the hunter biden laptop saga. you can steal the dimensioned drawings for parts a lot easier than you can get hunks of unobtanium or insight into forming such a material, which i assume is a dreadful process. i would expect the materials science to be a much more guarded secret than the aerospace knowhow

But seriously when’s the last time the Marines actually did anything related to being marine? They apparently decided they were some kind desert troops for the last 30 years so they could drive around in humvees thousands of miles from the nearest beach.

The marines should have just retrofitted ski jumps on the amphibious assault ships rather than deal with the F-35B. I guess they really need the deck space for more helicopters, or maybe some dingus in the USMC is still obsessed with jets ~operating from FOBs~ like they were with the Harrier, Falklands, etc. but can you imagine the delicate little flower that is the F-35 operating out of a dusty rear end FOB? Of course the real reason they committed to a VTOL F-35 is for grifting neoliberally, but still it's funny to think about.

I'm sorry, why are the Russians bragging about a fire proof fuselage? Is that not standard on military aircraft? Because it sounds really important.

Well in the video the airplane fails to take off and scrapes the bottom along the runway without actually catching fire.

China was able to control the balloon so it could make multiple passes over some of the sites (at times flying figure-eight formations) and transmit the information it collected back to Beijing in real time, the three officials said. The intelligence China collected was mostly from electronic signals, which can be picked up from weapons systems or include communications from base personnel, rather than images, the officials said.

The three officials said China could have gathered much more intelligence from sensitive sites if not for the administration’s efforts to move around potential targets and obscure the balloon’s ability to pick up their electronic signals by stopping them from broadcasting or emitting signals.

Yangtze Campaign, 2073 - 2077 posted:

American forces invaded east-central China in 2074 and remained there until the Great War in October 2077. During its course, American T-45 power armor units, infantry and mechanized divisions were deployed in China, but they became bogged down on the mainland, putting a further drain on American resources and supply lines.

The tide of the war was changed in 2076 when T-51 power armor finally finished development, and the first unit was sent to China where they finally began to beat the Chinese forces. Chinese supply lines from the nations China had annexed began to break down, leading to the loss of the major cities of Shanghai and Nanjing.[1][2]

Oh, yeah. That's pretty common. poo poo can get dicey, especially if any kind of flammable catches fire, but that's pretty normal stuff and isn't the same as being "fire proof"

You can find pictures of all different sorts of airplanes sitting on their belly either due to mishaps on takeoff, on landing, or as deliberate belly landings in response to damage or some other failure.

"just lift it up and it's good to go" is probably oversimplifying some repairs, but I'd believe a SU-25 can belly land and return to service. A-10s are the same, with how their gear is set up and designed, plus engine placement. SU-25s are sturdy, especially with the upgrades they got with lessons learned in Afghanistan, to firewall the engines from one another more sturdily so they were less likely to lose both engines to one shot.

It took substantive repairs, but a B-1B and F-22 scraped to a halt on their bellies and were repaired and returned to service.

This was always a goofy looking one:
