Pulshuttle V is a period-30 pre-pulsar shuttle oscillator found by Robert Wainwright in May 1985.

A 48-glider synthesis of this oscillator was found by GUYTU6J on June 2, 2021. The synthesis cost was later reduced to 47 gliders. A 46-glider synthesis was found in April 2023. On March 31, 2025, KtT lowered the cost to 44 gliders.
