S-310

S-310 is a Japanese sounding rocket. The S-310 is a middle-size rocket for carrying various payloads. It is a single-stage sounding rocket, 310 mm in diameter, and can reach an altitude of 200 km. Its predecessor, the S-300, was developed for observations in Antarctica, in parallel with the S-210, and reached 160 km altitude in its first flight in the fall of 1966 (PT-300). Two out of three succeeding flights had body trouble, which was later attributed to an unusual increase of the attack angle due to pitch-roll resonance.
