Submarine combat systems are large, highly complex, mission-critical system
s that provide the crucial combative capability for this increasingly impor
tant area of naval operations. The consequences of system unavailability or
malfunction can have dramatic and detrimental consequences for the safety
of the crew, the success of combined operations and the security of the nat
ion. The need to establish correct system implementation prior to acceptanc
e into service, is vital for the ability of the platform to perform its rol
es with any degree of confidence. System integration provides this confiden
ce and establishes the system's ability to undertake its prescribed roles i
n a structured and incremental manner.
