The funny thing about all of this is that pre WW1 much of the chemical industry worked with tree sap or tree resin as it was easier to fraction and process in the older chemistry plants than crude oil was.

There was a whole industry [in Europe at least] where people collected resin from their forests, lightly scoring their trees similar to how it is still done in Asia with rubber trees.

Alright then let me clarify:

There is no such thing as a next gen engine. They are just engines. The F119 and F135 are impressive beasts. But the EJ200 has a thrust to weight in the same range. Snecma M88 is close to it. Thrust vectoring, several non 5th gen planes have such capabilities. Also 5th or 6th gen planes...claimed ones? developed ones? claimed to be developed ones? If we are talking about the latter then shooot we have many of those, even former Yugoslavia claimed to have developed a stealth fighter.

Calling out certain brands also makes little sense since most NATO members and NATO alies are codeveloping engines now a days. EJ200 was British/German/Italian/Spanish companies co-developing it. F136 upgrade to P-W F135 was a G-E/Rolls Royce co-development.

Japan has co-developed with G-E to produce their next engine for their sixt gen fighter. Their current F-2 [a home made F-16 upgrade under licence] uses a home built and upgraded F110.

No idea where China stole it's designs, but they did upgrade them past what they were.

The indian engine has been in a test/research stage for ages and will continue to be in a test research/stage for at least a decade or two.

There are 7 nations that design and produce jet engines + 2 who successfuly reverseengineered and produce stolen designs.

India is in neither of those groups.

And yet, they still cannot protude a locally made jet engine of sufficient power and realiability for a fighter jet so they are fully reliant on external suppliers. Whoever they chose.

ISO Enter. Then it's good.
