'''SSI-87''' (project designation '''CY-3''') was the third launch of [[Cycloon|Project Cycloon]] on June 1, 2019. It featured a legacy ballast and vent mechanism from ValBal operated by Cycloon avionics and was the first such fully controlled Cycloon flight. The mission was noted for its eventful manual equilibration, early termination, and for being the last latex Cycloon before the project transitioned to polyethylene.
