초록

본 연구는 공개자료 기반 시나리오를 통해 디젤-전기, AIP·리튬이온전지 및 원자력추진 잠수함의 전개시간, 현지 작전시간과 스노클 노출을 비교하였다. 분석 결과, AIP는 저속 초계 중 스노클 노출을 줄였으나 원거리 전개의 시간적 제약은 남았다. 반면 원자력추진은 전개시간을 단축하고 현지 작전시간을 확대하는 것으로 나타났다. 또한, 쉬프랑급 사례를 통해 이러한 시간적 이점을 실제 운용 효과로 전환하려면 저소음 추진, 체계통합, 핵연료 관리 및 정비·인력 기반이 함께 확보되어야 함을 시사하였다.

Abstract

This study compared the transit time, on-station time, and snorkeling exposure of diesel–electric-powered, AIP–lithium-ion battery-powered, and nuclear-powered submarines using scenarios based on publicly available data. The results showed that AIP reduced snorkeling exposure during low-speed patrols but did not eliminate the time constraints of long-range transit. By contrast, nuclear propulsion shortened the transit time and increased the on-station time. The Suffren-class case further indicated that translating these time advantages into operational benefits requires low-noise propulsion, system integration, nuclear-fuel management, maintenance infrastructure, and a trained workforce.
