The Mogami Class FFM cost less than US$500 million to build per ship. Vital statistics for it and the RAN Anzac Class are:
Length 130 meters (426 feet 6 inches) (Source) 118 meters (387 feet) overall Beam 16 meters (52 ft 6 in) (Source) 14.8 meters (49 ft) Draft Unknown 4.35 meters (14.3 ft) Standard displacement 3,900 tons 2,900 tons (Source) Full load displacement 5,500 tons 3600 tons Range Unknown 6000 NM (11000 km) at 18 knots (33 km/h) Speed 30+ knots (Source) 27 knots (50 km/h) Compliment 90 177 VLS cells 16 8
