Page "C-802" Paragraph 3

When the missile is launched, the solid rocket propellant booster accelerates the speed of the missile to Mach 0. 9 in a few seconds.

After the booster burns out, it detaches from the missile body and the missile's turbojet engine starts working.

Controlled by the inertial autopilot system and radio altimeter, the missile flies at a cruising speed of Mach 0. 9, and the cruise altitude is reduced to 10 – 20 metres ( depending on the sea state ) from the original 20 – 30 metres of the C-801 / YJ-81.
