Four legs extend downwardly from the support base and pedestal connecting means are secured to lower ends of each of the legs. The four pedestal adapters serve to secure the legs to existing launch vehicle support posts, the pedestal adapters each having adapter connecting means complementarily engageable with the pedestal connecting means. The umbilical mast comprises a plurality of round cylindrical segments connected by means of connectors at their ends. The connectors comprise radially extending flanges with circumferential holes in them. The mast further includes an access door and at least one opening in at least one of the segments for electrical cables and an air conditioning duct.
