please explain what is Area 51?
Click to expand...
To put it simply, Area 51 is a highly-classified air base in Nevada, USA, that has been used for supporting the development and testing of experimental aircraft and weapons systems for the USAF (and before that, the CIA) since the mid-1950s, including the U-2 and SR-71. Due to the intense secretive nature surrounding the site and the extreme lengths of security and information control around and about the site itself (and the projects undertaken within the site), Area 51 is a frequent subject of many conspiracy theories.

(However, disclaimer - I do not claim that the PLAAF site mentioned in that Twitter post above corresponds to/resembles the actual features and functions of Area 51 in any way.)

PLAA's Shijiazhuang Flight Academy summarized their experience, innovated training methods for close range air combat, and made the training more practical, reducing the flight duration during the training cycle for third-generation aircraft pilots by 300–400 hours.

Shijiazhuang Flight Academy is the experimental unit for the new mode of training pilots. A few years ago, the academy received a batch of third-generation machines. Meanwhile, they began to try to let novice pilots directly fly the advanced Trainer after completing the courses on the primary trainer.

Does china have a LRASM equivalent?

There are several target drones with the same characteristics.

I'm not anywhere near a field expert, but isn't the whole point of LRASM it's sea skimming and maneuverability capability, which exists across all the current gen VLS/launcher based hypersonic/high supersonic PLA anti ship missiles as well?

The difference is that China has guidence technology which bypasses the plasma sheathe from hypersonic weapons which would otherwise render guidence impossible. So in essense China doesn't seem to need a subsonic sea skimming missile, because it can use much faster missiles with the same profile.

Why copy LRASM when you can stuff YJ21 into the same VLS, which is much much harder to intercept and likely represents a tech branch that has more long term potential compared to subsonic?

The only area where China has experimented with subsonic munitions is on plane borne ones, these are way more similar to smaller sized storm shadow rather than bigger LRASM. Here, there's an obvious incentive because the heavier hypersonic weapons can't fit on multirole jets.
