| dc.description | This work aimed at proposing a new combination of technologies to improve military
performances and reduce costs of nuclear attack submarines, without overlooking
safety constraints. The last generation of nuclear attack submarines increased size
to meet safety and operational requirements, imposing huge burden on costs side,
reducing fleet size. The limitations of current Technologies employed were qualitatively
discussed, explaining their limitations. There are new technologies (plate and
shell heat exchangers) and architectural choices, like passive safety, and segregation
of safety and normal systems, which may lead to reduction of costs and size of submarines.
A qualitative analysis was provided on this combination of technologies,
stressing their commercial nature and maturity, which reduced risks. The qualitative
analysis showed the strong and weak points of this proposal, which adopted the concept
of strength in numbers. Concluding, new Technologies enabled the existence of
3800 t nuclear attack submarines with powerful propulsion systems and good acoustic
discretion. | |
