The first HASTE flight to reach orbital velocity - all prior HASTE missions were strictly suborbital. Upper stages were tracked in a roughly 200 km orbit at 40-degree inclination, and Rocket Lab confirmed the insertion was deliberate. The customer and payload were classified; the payload is believed to have completed a single orbit before reentry recovery downrange.
