Last analysis:
The new HS-12 missile is up to now a mystery. In any case, it is a single-stage
rocket with a diameter of about 1.50 m. The cablel duct is on the entire
length not interrupted and there is no indication of a stages separation
plane. The engine bay suggests that the missile uses not a SLBM-like
engine. The cable duct ends higher up and it is to see a slightly conical
skirt with weld seam, which means that an engine is used not inside
the tank as for HS-10 or HS-13. In addition, the bottom in the skirt
is plane. The assumption, the missile uses the recently
tested engine (one combustor of RD-250) is probably true. The added
steering engines comes from the HS-13 (R-27 origin). The takeoff thrust
is approximately 464 kN. The fuel would be consumed after 120 seconds.
The WH is equipped with a telemetry antenna and obviously also with
a extra PBV.
