was located on top of the existing structure
and over Room 15. It consisted of a 10x14x8-
foot-high wood shelter on a concrete slab. The
14-foot north wall of the shelter contained two
5x6-foot wood drop doors and the roof had a
5x12-foot opening with an automatic opening
hatch cover. This cover was operated by a motor-
driven screw shaft located on a steel A-frame at
the roof level but operated from within the
shelter. This structure was air-conditioned by
a window-type unit on the wall. With the relocation of the ABMA Program, this facility
was cancelled.
This bunker was a heavily reinforced con-
crete structure of irregular plan designed to
survive the CACTUSevent. Sidewalls and front
wall facing Station 20 were earth barricaded
to roof level. The foundation slab was 3 and
4-foot-thick, walls were 214, 3, 4, and 5-footthick, and the roof slab was 3 and 3144-footthick. This structure was a terminal of a Vacuum
Pipeline Station 1131, running to Station 20.
The structure was of Z-shape, 2614x18 feet
overall in plan, containing a single 5-foot-square
room space and an L-shaped entrance passage
from a removable entrance blast door. An ac-
cess tunnel 28
feet long was through one
earth barricade slope to a vacuum pipe, connecting chamber situated on the Station 20
