DESIGN VARIATIONS

	Two main variants of the Galaxy class Battle Bridge have been 
installed on the USS Enterprise since the starship was constructed. Each has 
been designed as a replaceable module; swapout is accomplished through a 
series of electrohydraulic jackscrews in the Battle Section head and 
structural looking clamps around the base and periphery of the module. 
Periodic upgrades will be tested out during the entire operational cycle in an 
effort to maintain adequate defensive capabilities; each Galaxy class 
starship will always exhibit some minor differences when compared with its 
dockmates.
	Similar design philosophies drove the internal arrangement of the 
Main Bridge and Battle Bridge. The latter maintains an aft equipment bay 
housing computer optical subprocessors, as well as power, environmental, 
and optical data network trunk connects. Additional computer 
subprocessors are located in smaller port and starboard equipment bays, as 
well as in the armored forward bay enclosing the main viewer.  Æ
