@foraustralia2558 Reminder
Australia's coastline = 35,877 km
France's coastline = 5,500 km
Scorpène-class submarine with submerged 2,000 tonnes displacement has 550 nmi (1,020 km; 630 mi) at 5 kn (9.3 km/h; 5.8 mph) (submerged). Scorpène has 6,500 nmi (12,000 km) at 8 kn (15 km/h; 9.2 mph) (NOISY surfaced).
Attack class's displacement is higher due to extra fuel, AIP and battery packs, hence Attack-class has 18,000 nmi (33,000 km; 21,000 mi) at 10 kn (19 km/h; 12 mph) NOISY surfaced.
Collins-class submarine with submerged 3,407 tonnes displacement has 480 nmi (890 km; 550 mi) at 4 kn (7.4 km/h; 4.6 mph) submerged. Collins has 9,000 nmi (17,000 km; 10,000 mi) range at 10 kn (19 km/h; 12 mph) periscope depth (semi-NOISY).
Sōryū-class submarine (submerged 4,200 tons displacement) 's AIP endurance (est.): 6100 nautical miles (11297.2 km; 7060.75 miles) at 6.5 knots (12 km/h; 7.48 mp/h). Sōryū-class submarine's AIP is based on Swedish AIP designs.
The submerged range difference between the Scorpène and Collins submarine designs is relatively minor.
Most containerships are designed to travel at speeds around 24 knots.
Attack class submarine will NOT solve silent mode short range and the capability for shadow escort at cargo ship's speed and range.
