SpaceX is building yet another "Mechazilla". This one is rising at Space Launch Complex 37 on Cape Canaveral Space Force Station. It will be the fourth such tower built overall, following two at Starbase in Texas and one already standing at Kennedy Space Center's Launch Complex 39A.

SLC-37 has a long history. Built in 1959 for the Saturn rocket program, it later hosted United Launch Alliance's Delta IV and Delta IV Heavy rockets until that vehicle's retirement. The old Delta IV infrastructure, including its mobile service tower and lightning protection masts, was demolished by controlled implosion to clear the way.

SpaceX's plans for SLC-37 are huge. Two separate Starship pads and supporting infrastructure, designed to support up to 76 Starship/Super Heavy launches per year and 152 booster and ship landings combined.

After foundation work and the arrival of tower modules at the site, SpaceX rolled out the first section of the SLC-37 tower in February 2026. By June, cranes had lifted the first actual tower module into place, marking the formal start of stacking the structure. The same process used at Starbase and LC-39A, where modular steel segments are welded together and lifted into place one on top of another to form the finished tower. By now this starts to become routine for SpaceX.

Supporting construction is moving in parallel. Crews have been driving piling foundations for a large propellant tank farm meant to feed both planned pads. A new area is being cleared nearby for an air separation unit, which produces liquid oxygen and liquid nitrogen by processing ordinary air.

Over at LC-39A, roughly nine kilometers away, the tank farm and modified catching arms are already being tested. Having two separate Starship sites in Florida, on top of Starbase in Texas, gives SpaceX true redundancy. If one pad needs repairs or is busy, missions can shift to another, supporting both higher launch cadence and the refueling missions Starship will eventually need for lunar flights and beyond.

No firm date has been given for the first launch from SLC-37. A first flight from the pad is unlikely before 2027. But the rising steel at SLC-37 proves that Florida's Space Coast is becoming a second home for Starship.
