Horizontal Integration Facility

A horizontal integration facility (HIF) is a location within which the stages of a multistage rocket are brought together, before the assembled stack is rolled out to the launch pad or complex (LC) and raised into vertical position for launch.

Cape Canaveral Air Force Station SLC-37 Delta IV 28°31′25″N 80°34′15″W / 28.5234928°N 80.5709624°W / 28.5234928; -80.5709624 A seven-story white building containing 2 bays measuring 250 feet (76 m) by 100 feet (30 m) each. Construction was completed in June 2000. Its floors are said to be the most level in the US[1] varying only 3/8 inch across each bay. The first and second stages of the rocket, along with any boosters that are being used for that flight, are integrated in the HIF, and then the stack is moved to the pad and raised to vertical. The payload and fairing are assembled later.

HIF elsewhere[edit]

Most Russian, Ukrainian and former Soviet launchers are integrated horizontally including Dnepr-1, Proton, Rockot, Shtil' and Soyuz.
