Taigei-Class Attack Submarines

JPN Submarine Modern Tier 10 Power 675.91

Latest Japanese Submarines - Taigei-class are Japan's newest attack submarines. 5+ boats commissioned 2022-2025+ (ongoing program). Improved Soryu design: Same size (4,300 tons), but all lithium-ion batteries from start (no AIP - learned from SS-511/512). Enhanced automation, improved sensors (Type 18 sonar), more powerful electric motor (6,000 shp vs Soryu's 2,900). Better hydrodynamics, reduced acoustic signature. 6 torpedo tubes, 30 weapons. 650+ meter test depth. Crew 70 (vs Soryu's 65 - slightly larger despite automation). All active as of 2025. Represent latest evolution of Japanese submarine technology. Will replace remaining Oyashio-class boats. Expected total: 7-10 boats over 2020s-2030s.
