Standing tall — 1979
Jul 10, 2021
Almost fifteen years after the completion of Mobile Launcher 3, the construction of ML-4 and 5 was commissioned by NASA from Ingalls Iron Works. $25mn each and 380 feet tall, the two new mobile launchers and their associated Launch Umbilical Towers were fitted to support crewed and un-crewed launches of Saturn V and Saturn I+ boosters.
Built on site, both launchers would play key roles in the Ares Programme, launching test flights of the Caelus Interplanetary Injection Booster and the Mars Exploration Module, as well as KS-IVB Orbitankers.
