I think that with China's manufacturing prowess, it will be extremely difficult for the US to win an arms race against China, despite its pipe dream such as the "Replicator" program.

‘War of money’: can China drag rivals into bankruptcy in a new arms race with drones?​

  • A new low-cost engine for Chinese drones has cut the price to less than 20 per cent of the international figure
  • The technology is set to start a drone arms race as the US begins its own programme to ramp up production
But thanks to a recent technological breakthrough, the People’s Liberation Army can now get drone jet engines with superior performance at less than a fifth of the international price, engineering thermal physicist Zhu Junqiang said in a presentation about the project released by the Chinese Academy of Sciences on October 19.
...
But the PLA was quick to embrace the new engine, mainly because it had a lot of things going for it: it consumed nearly a third less fuel than the two-shaft engines and its maintenance costs were significantly cheaper due to having 70 per cent fewer mechanical components.
The total cost to buy and run the drone engine was therefore reduced by about 80 per cent.

Stop posting garbage from SCMP. Stephen Chen didn‘t even get some basic facts right

I found the original article/talk:

Zhu's team actually developed three different engines suitable for different types of drones, which the SCMP garbage article didn't seem to understand. The first is a turbojet with an afterburner, which is important because micro turbojets generally don't have afterburners. The second is a micro turbofan that can operate at 60,000 ft, which is important because high altitude makes engines more efficient and gives drones longer flight time and range. The third engine is the single spool turbofan engine, which is the world's first as all other turbofans are two or three spools. Traditionally, single spool jet engines are turbojets. The single spool turbofan is more fuel efficient than turbojets by 28.5% while 80% cheaper than two spool turbofans.
