On the ocean two hundred nautical miles east of Pannu Islands, with the escort of the frigate installed with the Type-50 J-unit electromagnetic pulse cannon, two construction vessels were deployed on the surface and retrieved the first stage rocket falling with under engine propulsion.
In the distance, there were a few patrol boats without flags. While maintaining a safe distance, they monitored the first stage rocket launch vehicle retrieve work. Because they were in public sea area, thus Celestial Trade's frigate didn't bother with the monitoring boats. Also, the boats just aimed its cannon in the distance as a warning.
When the first stage launch vehicle successfully landed and was transported onto the construction vessel, the patrol boats retreated.
