Comparing the Effectiveness of Nuclear and Air-independent propulsion Submarine Fleets

This article proposes a methodology that enables one who has actual cost figures to perform the calculations for benefit-to-cost, strictly from the tactical and logistical standpoints, on the performance equivalence not of nuclear vs. air-independent-propulsion (AIP) submarines, but of nuclear v. AIP submarine fleets. With that in hand, it becomes possible for whomever might have sounder figures than what we could find about the complete life-cycle cost of either alternative to figure out, given our results about the benefit assessment, what would be the result of a benefit-to- cost analysis. We didn't perform the latter, due to uncertainty about the methodology by which the public available cost estimates were calculated. By providing a method for benefit calculation of the military worth of alternatives to support an assessment of the SSN/SSP fleet alternatives, we hope to have provided a sounder point of departure for debate, both in general terms, a method, and for the Brazilian case in particular, an application.
