Its funny the Italian design is part of a joint program with the French! My guess is the French wouldn’t mind being dropped given they’ve bagged the bigger prize of the sub contract.
About contenders, the Spanish are building a new frigate class, but I’m not sure if it will be ready on time for Australia/export considerations. Sad that the Mitsubishi offering wasn’t considered.
Or maybe because they didn't bother to build a model with CEAFAR2 radar (^_^)
