Spacex starship orbital flight forecasts

SpaceX is transitioning to the 'Block 3' (V3) Starship architecture, which is designed for orbital missions and deep-space capabilities Verified Answer #1. As of May 12, 2026, the company has completed 11 suborbital test flights, the most recent of which occurred in October 2025 Verified Answer #1. Technical indicators and regulatory filings suggest an orbital flight will occur before the end of 2026 Verified Answer #1.

Flight Schedule and Technical Milestones

• Flight 12 is scheduled for May 15, 2026, following a successful full-stack launch rehearsal on May 11 Verified Answer #1.
• While Flight 12 is expected to follow a suborbital trajectory, it serves as the debut for Raptor 3 engines and the V3 airframe Verified Answer #1.
• Regulatory filings confirm that Flight 13 is explicitly targeting an orbital trajectory Verified Answer #1.
• An FCC Special Temporary Authority application for Flight 13 was modified in April 2026 to include an orbital second stage, with an operational window opening May 29, 2026 Verified Answer #1.

Strategic Objectives

SpaceX has stated a goal of completing 12 orbital flight tests in 2026 Verified Answer #1. These flights are intended to demonstrate rapid refurbishment and validate in-space propellant transfer Verified Answer #1. Such demonstrations are mandatory milestones for NASA's Artemis HLS program Verified Answer #1.

Infrastructure and Risk Assessment

The FAA authorized up to 25 annual orbital launches from the Boca Chica site in a February 2026 environmental assessment Verified Answer #1. The primary risk to the orbital forecast is a potential catastrophic pad failure at Orbital Launch Pad 2 during Flight 12 Verified Answer #1. Despite this risk, the probability of achieving at least one full orbit in 2026 is considered high due to a significant hardware pipeline that includes Ship 40 and Ship 41 Verified Answer #1.
