They mentioned target drones. Those are definitely designed to be recovered if the missile misses.

right, so maybe not single use. But I wonder if they might also be designed with lower service life. probably so
Asking for long service life with this kind of scrape the bottom of the barrel prices is too greedy I think.
well, we don't know what the price is. So the question is whether you can produce higher end mostly 3D printed engine if you were using better material & such. Or with current tech, you can only produce lower end engine.
this following is actually on gas turbine, but I found something that is quite applicable to turbofan engines.
so they got the gas turbine tested in -55C condition. Looks like here 300+ companies, 10k+ engineers & 80B RMB investment. the blade needs to withstand 1500C high temperature. They used 3D printing layer after layer and metals powder dope with Rare Earth. Keep trying this out and wasted 12t of material just to develop one type of single crystal blade. This allowed them to raise service life from 400 hours to 2000 hours. 98% of gas turbine's core components are domestic, including blade, coating and control system.

First page is targeted thrust
黄维娜 Huang Weina is a now an academician at the Chinese Academy of Engineering
What is far more interesting is 719th institute here, they do naval nuclear power. Possibly 004 or 095?
