7.3.1. Booster Assembly Stacking/Launch Site Preparation
Prior to the arrival of the Minuteman boosters, the site is prepared for launch operations with the
installation of the launch stand adapter. The Lower Stack Assembly, consisting of the Minuteman motors,
is delivered directly to the launch pad from Hill Air Force Base. Following emplacement, the Upper Stack
Assembly is horizontally transported from the MPF to the pad and emplaced, as shown in Figure 7.3.1-1
as performed at VAFB SLC-8.

Assembly, and the Encapsulated Payload Assembly
7.3.2. Final Vehicle Integration and Test
After the vehicle is fully stacked at the pad, final tests are completed to verify vehicle integrity and all
interfaces to the range are exercised. A range interface test is performed to verify all the RF systems, and
an end-to-end FTS test is performed to certify the FTS system. The ACS and separation systems are
pressurized to final flight pressure, and final vehicle preparations are accomplished. The vehicle and
launch team are then ready for the final countdown and launch.
7.3.3. Launch Vehicle Arming
Following final vehicle testing, the launch vehicle is armed and the pad is cleared for launch. The majority
of these arming activities occurs at L-1 day and brings the Minotaur launch vehicle nearly to its launch
day configuration. L-1 day is also typically the last opportunity for payload access. The remaining arming
steps (final arming) take place mid-way during the countdown on launch day.
