FIRST FLIGHT 27 MAR 2025MISSION DATE

Swift X-2 is a piloted supersonic research aircraft built to validate low-boom shaping, hydrogen-assisted turbine operation and real-time atmospheric route planning. It conducts flights from the Meridian Flight Research Annex.

Community-response measurements are collected only under approved corridors and are published with independent acoustic calibration records.

LATEST OPERATIONAL UPDATE

Sortie X2-031 completed the first high-altitude low-boom measurement line over the South Ocean corridor.
