096 is unrealistic because we have no indication of it starting construction, 095 is more likely to be shown
Even 09V would be a stretch in 2027. Even if we say 09V is launched today, the lead boat entering service within 2 years is not impossible, but would need to be speedy for what is a whole new SSN class in every sense of the word.
And even if it managed to enter service in 2027, the idea of the PLAN officially showing a new nuclear submarine that has just entered service months ago, is very unlikely.
09IIIB reveal in an official capacity in 2027 is more viable.
