Based on the Pentagon report, it seems like H-20 will not have as much range as B-2 or B-21. I don't think that's a problem. For PLAAF's medium term goals, combat radius of 4500 km with fully weapon loads is sufficient to cover Guam (3000 km from Shanghai to there), all of East Asia, India, Southeast Asia and even Northern corner of Australia. Future upgrades of engine and material could allow it to cover even larger area. What they need is something that can fly in undetected against defended military installations without escorts, drop bombs and fly away undetected. That's something they don't have right now with H-6K, which has to rely on LACMs. LACMs are expensive and limited in supply. Large bombs are not. As I described in the Taiwan scenario, having a modern strategic bomber that can take out military bases with large amount of bombs is critical. Maybe it will not be stealthy enough to survive the most heavily defended air space, but should be LO enough to take out other military bases. That's something only US can do right now.
