SpaceX Starship V3 Debut: Flight 12 Achieves Suborbital Insertion and Payload Deployment Despite Dual Engine Anomalies

SpaceX has launched the inaugural Starship Version 3 (V3) vehicle on its Flight 12 suborbital test, validating structural redesigns including a modified staging interface. Despite experiencing independent engine dropouts on both the Super Heavy booster and Ship 39 upper stage, the vehicle achieved its target trajectory and successfully deployed 22 payloads.

Flight Profile and Propulsion Anomalies

SpaceX conducted the first suborbital test flight of its Starship V3 architecture on May 22, 2026, at 22:30 GMT from the newly commissioned second launch pad at Starbase, Texas. The flight, designated Flight 12, aimed to validate a comprehensive design overhaul intended to transition the platform toward operational mission capabilities.

The propulsion systems encountered two distinct anomalies during the ascent phase. During liftoff, one of the 33 Raptor engines on the Super Heavy booster shut down prematurely. During the upper-stage ascent, Ship 39 lost one of its six main engines. Despite the loss of redundant thrust, the upper stage reached space utilizing its remaining five engines. Mission controllers confirmed that while the ascent did not meet nominal orbital insertion parameters, the resulting trajectory fell within pre-analyzed safety and operational boundaries.

Structural Redesign of the Hot-Staging Interface

Flight 12 marked the first flight test of the V3 staging architecture. At approximately 2 minutes and 20 seconds into the flight, the vehicle initiated hot staging.

Unlike the V2 iteration, which utilized a jettisonable interstage ring that separated from the vehicle, the V3 design integrates fixed hardware secured directly to the top of the booster. This structure functions as a protective barrier around the dome of the booster's fuel tank, providing the necessary clearance for the upper stage engines to ignite and establish initial thrust without the mechanical complexity of a deployable ring.

Booster Recovery Failure

To protect the newly completed launch pad infrastructure from potential recovery mishaps, SpaceX opted out of a mechanical catch attempt using the tower's "chopstick" arms. Instead, the flight profile dictated a soft splashdown of the Super Heavy booster in the Gulf of Mexico.

Following stage separation, the booster attempted a one-minute boostback burn to control its return vector. However, the maneuver failed to execute as planned. The booster did not complete the full burn duration, resulting in a high-velocity impact into the Gulf of Mexico rather than a controlled splashdown.

Payload Deployment and Thermal Shield Inspection

Approximately 17 minutes after liftoff, Ship 39 initiated a 10-minute payload deployment sequence utilizing its PEZ-dispenser mechanism.

The payload manifest consisted of 22 items: 20 dummy Starlink simulators and 2 functional Starlink satellites equipped with specialized imaging sensors. Following deployment, these two active satellites (designated "Dodger Dogs") operated in close proximity to the upper stage. The satellites successfully executed optical scans of Ship 39’s thermal protection system tiles to assess the feasibility of performing automated, in-orbit damage inspections prior to atmospheric reentry, transmitting high-resolution imagery back to ground stations.
