Titled: Is China selling stolen weapon designs?
4:40 - from 4:40 it gets most interesting describing China is reverse engineering, improving on Russian weapons eg. China's HQ-17 SAM system based on Russia's Tor Missile System.
5:05 - China's cheaper labour mass production (and in some cases export) of Russian weapon systems avoids high development costs. In some cases China has sharply reduced unit production costs for the Chinese military while hurting Russia (which has lower export sales for systems China has copied).
5:27 - for the F-35 the US has suffered the high development cost per factory unit production problem. [With I suspect, Lockheed, US State and Defense Departments pressuring US allies (eg. Australia, Japan and in Europe) buy F-35s to cut unit costs for US military.]
5:32 - Chinese competition and high Russian aircraft development costs means Russian built aircraft are becoming more expensive - so Russia can afford fewer aircraft "while Chinese knockoffs can become a lot cheaper the more China can sell."
5:44 - US spends $Billions on weapon system design and development phases. If China can skip design - development this can save $Billions
5:57 - yet as well as reverse engineered copies China does do adjustments, improvements
6:20 - China has stolen F-35 secrets, [eg. Su Bin "managed to grab volumes of data relating to the F-22 and F-35"]
[Pete Comment: advisable US collects J-31 data (eg. in future 3rd country buying one) as its just the type of 5th Gen Minus ("5G-") medium size and high power/weight ratio that USAF Chief Brown has have been talking about].
6:38 - if/when China surpasses US and Russian tech Chian will no longer have as many money saving design/devel skipping opportunities
6:52 - China's DF-21D anti-ship [carrier killer] ballistic missile is a case of a unique Chinese development surpassing the US. Although DF-21D devel has been extremely expensive for China with 15 years (initial design to first test)
7:20 - China now "cutting edge" of hypersonic missiles (eg. DF-ZF boosted by DF-17s ).
7:28 - Chinese gov often claims new weapon systems are operational long before they actually are.
7:36 - so copying can save years and $Billions in development but (Covert Cabal claims) you can never be No.1 technologically
7:50 - China getting to point it can develop its own advanced weaponry - in some cases more advanced than Russia or the US.
