Orbital Launch and Integration Tower 4 (OLIT #4) is a potential second launch tower for Starship at Cape Canaveral. It was first mentioned in a March 03, 2025 update from SpaceX, where they mentioned surveying Space Launch Complex 37 (SLC-37) for "further due diligence and to move forward with the Environmental Impact Study" for use as a second Starship launch location.
However, it could be speculated that the tower may again be built at LC-39A next to OLIT-2, to re-use the existing infrastructure; but this is a speculation.
Current facilities at Cape Canaveral are one launch tower (OLIT-2), which is to be completed in 2025. SpaceX also plans to build a new Gigabay with planned completion at end of 2026, and a Starfactory-like production facility at Cape Canaveral.
Site[]
SLC-37 is a launch complex located on the grounds of the Cape Canaveral Space Force Station (CCSFS), some 9 km away from the existing launch tower, OLIT-2 at LC-39A.
The complex consists of one pad not in use, and another pad used by the United Launch Alliance for Delta IV and Delta IV Heavy launches until 2024. On April 9, 2024 the last Delta IV Heavy was launched from the site, and the Delta IV was subsequently retired.
Since then, the ULA has not used the site; Vulcan Centaurs are launched from another pad, the SLC-41. The 100-meter-tall Mobile Service Tower (MST) for Delta IV remains standing at the site.

On 27 July, NSF's Greg Scott spotted first segments of the next tower on a flyover over SpaceX's Robert's Road facility.[1]
3 March 2025 - SpaceX web update[]
«To support the needed Starship flight rate to make humanity a multiplanetary civilization, which involves not only the launch of cargo and people but also the propellant tankers to enable on-orbit refueling, SpaceX is also interested in enabling Starship launches from SLC-37 at CCSFS. SpaceX has been given a limited Right of Entry for SLC-37 in support of conducting further due diligence of the site in order to move forward with the Environmental Impact Study (EIS), led by the Department of the Air Force, for Starship and Super Heavy Operations at CCSFS.[2] »
