BEIJING, April 6 (Global Times): The J-20, the most advanced, stealth-capable fighter jet of the Chinese People's Liberation Army (PLA) Air Force, has entered the next level of combat readiness, analysts said on Monday, after the aircraft was spotted flying without a Luneburg lens, a small device used to intentionally expose a stealth aircraft to others in situations like training or non-combat flights.
