The proposed division is between a heavier frigate for demanding task-group work and a more affordable presence or picket frigate. Type 26 supplies the high-end ASW and escort element, while Type 31 offers a less costly hull for routine presence and screening. New Zealand is a particularly good candidate for the lighter family when its Anzac frigates need replacement. Additional Commonwealth or allied buyers could widen the production base without requiring Australia or Canada to adopt the same high-low ratio.
