Second, the Australian airforce and Boeing developed this plane together and have already had it in service for many years with fantastic success and reliability.
I believe the UK RAF also has some in service.
It’s been operated with many of our allies on joint operations and sometimes with observers as they all knew that their AWACS fleets were in pretty desperate need to be replaced and were accessing it.
It is by far the most capable platform of this type, and it’s a ready to go mature design that the countries looking to come on board have already been operating along side and supporting in real operations.
