The Yilong 3H rocket features an integrated fairing similar to that of the Neutron.

CapabilityGeneralValue 3.0Nov 2, 2025Oh and here's another render of that "Yilong 3H" which seems to combine Neutron-like integrated fairing with bundled 1st stage where the 3 cores don't separate and seem to land together - with ⌀5m & kerolox its scale seems big, probably >2000t at liftoff https://x.com/TAbusnardo/status/1983688368883147102

There are indications that Yilong 1 may have a design similar to Neutron's second stage S2.

Hangtian Yilong shows a render of 5m⌀ Yilong 1 A bit confused, earlier reports was that they aimed for full reuse, it seems it has Neutron-like S2 in fairing. Polis城邦工作室 says "S2 has retro-propulsive ability"

Old neutron stars that spin quickly, known as millisecond pulsars, could also explain the gamma ray observations.
