RAAF chief Air Marshal Geoff Brown said Russia’s PAK FA and China’s J-20 were years behind the F-35 in development.
“Let me tell you, I don’t think that they have the level of stealth that’s available in U.S. fifth generation aircraft, and it’s by a significant factor,” Air Marshal Brown told lawmakers.
“Both PAK FA, J-20 and J-31 are possibly where we were in excess of 10-12 years ago in their development time frames, so all those aeroplanes have still got a long, long way to go,” Brown said.
