The Hunter problem follows from a force structure with only three Hobarts. The air-defence shortfall has migrated into a programme originally centred on anti-submarine warfare. Australia is trying to retain a quiet ASW frigate while adding radar, power, and weapons for a larger air-warfare contribution. The Type 26's open architecture and growth potential make that adaptation possible, although choosing an enlarged hull from the outset would have left a better margin.

Why the Hunter design is being pulled toward air defence
A shortfall in Hobart-class air-defence numbers pushes Australia to add more air-warfare capability to the ASW-focused Hunter design.
