Block 4, Height Limits, and Production Constraints

SpaceX flew Starship five times in 2025. The first three flights lost their ships during ascent. A fourth ship exploded on the test stand. Then Flights 10 and 11 succeeded, proving Block 2 works. On January 4, 2026, Elon Musk said SpaceX could eventually produce 10,000 Starships per year. Meanwhile, the company is constructing Giga Bays in Texas and Florida, preparing five launch pads across two states, and recovering from the loss of its first Block 3 booster. Flight 12 is next.
