MAIN BRIDGE

	The central area of the Main Bridge provides seating and information 
displays for the commander and two other officers. Directly fore of the 
command area are the Operations Manager and the Flight Control Officer, 
both of whom face the main viewer.
	Directly aft of the command area is an elevated platform on which is 
located the tactical control station. Also located on the platform are five 
workstations, nominally configured as Science I, Science II, Mission 
Operations (Ops), Environment, and Engineering.
	Other facilities located on Deck 1 include the captainŐs ready room 
and head, the aft observation lounge, and the crew head adjoining the bridge 
itself. Both the bridge and the captainŐs ready room are equipped with food 
replication terminals.
	Major connects to the bridge include two standard turbolift shafts, 
one emergency turboshaft, and four electro plasma power distribution 
waveguide conduits. Additional connects include four environmental support 
plenum groups, nine primary and two backup optical data network trunks, 
two replicator waveguide conduits, and three service crawlways.
	Because of the criticality of bridge systems, especially in emergency 
situations, the Main Bridge is designated as an emergency environmental 
support shelter, receiving priority life support from two special protected 
utilities trunks. These feeds permit Class M conditions to be maintained for 
up to seventy-two hours even in the event of failure of both primary and 
reserve environmental systems. Also provided within the bridge shell are two 
emergency atmospheric and power supply modules, each capable of 
providing up to twenty-four hours of atmosphere and lighting in the event of 
total environmental systems failure.
	It is anticipated that the current bridge configuration of the Galaxy 
class starship will remain relatively unchanged for a number of years. 
Current planning calls for annual design reviews of the bridge and control 
systems, with major system replacements projected at twenty-year intervals.
