BRIDGE

The Main Bridge module is connected to the spaceframe structure with a 
series of 320 7.2 cm duranium fastening rods. These fasteners can be 
disengaged at major starbase layover, permitting disconnect and replacement 
of the entire bridge module. Torsion relief and vibration damping are provided 
by a series of 17 mm microfoamed AGP semiflexible ceramic gaskets which 
form the mechanical interface between the structures. The Main Bridge shell 
is constructed from an interlaced microfoam duranium filament shell gamma-
welded to a tritanium truss structural framework. The inner environment 
envelope is fabricated from low-density expanded ceramic-polymer composite 
segments, providing both atmospheric integrity and thermal insulation.

During the initial spaceworthiness tests of the original USS Galaxy prototype 
vessel, the standard Galaxy class bridge module was not yet fully operational. 
Instead, a custom-built module was used that was equipped with independent 
life-support and sublight propulsion capabilities. This unit was used as a self-
contained crew compartment during the initial shakedown and could have 
been ejected, carrying the crew to safety in the event of a catastrophic failure 
of the spaceframe or propulsion system.  Æ
