For Canadian crews, the KSS-III Batch II’s habitability is a real operational advantage for mixed male and female crews. The larger hull allows for a two-deck layout with separate or configurable berthing, increased privacy, and additional washrooms and showers, which reduces fatigue on long patrols. High automation keeps the core crew around the low-30s, so there is more space per sailor and less friction day to day. Paired with lithium-ion batteries that lengthen quiet endurance between snorts, these features help crews stay rested and effective on longer patrols across three oceans.
