Well, TBH I don't think any of that matters to most people here. Engineers and analysts both just tend to like machinery, systems, and the tech itself. This country or that, new or old, as long as something is clever, people will just love to figure it out.Hey, I think this is a punishment for them. They have to reluctantly watch China become stronger year after year, while they can only shout in vain like Indians.
Getting back to CCA/UCAVs though, or any new tech ever, don't discount the fact that countries use showmanship and secrecy in equal measure, as best befits their perceived better interests. It's all just poker.
When China finds it in their best interest to show their cards they will, and they will do so in the order that will maximally make the other poker players think twice if they want to stay in the game or go all in. Everyone shows their cards in the end though.
I do think China has a particular flare for the dramatic. After all, it isn't their first time at the poker table.
