How many uncrewed Starships were announced for launch during the 2026 window to test reliable landing?

Five uncrewed Starships

Following the successful fourth integrated flight test, which demonstrated controlled splashdown for both the Super Heavy booster and the Starship upper stage, SpaceX formalized plans for the initial precursor missions targeting the 2026 launch window. The specific objective for this window was to rigorously test the landing mechanisms on Mars. To achieve a robust demonstration of reliability, the plan involved launching five separate uncrewed Starships to the Martian surface during that transfer opportunity. The success of these five precursor missions was explicitly tied to the subsequent projection for launching the first crewed flights approximately four years later.
