There is no such thing as the H-10. The newest Chinese stealth bomber is the H-8 (which is about to enter service).
The H-10 was applied to a conceptual development of the Tu-22M3, which never came true. That was in the 1990s.
There are only 2 known bomber programs: the H-8 stealth bomber (about to enter service), and the H-9 atmospheric bomber (under development). No H-10.
And no B2 or F-117 technology were used either, according to XAC.
H-8 specifications:
- Speed: Mach 1.4
- Range: 11,000 km
- Weapons load: 18 tonnes
- Two weapons bays
- Weapons: bombs, nuclear weapons, cruise missiles, guided missiles, glide weapons, etc...
