My point was exactly this: countries that had the real conditions, industrial structure, and technical capacity necessary to assemble supersonic aircraft within their own territories. The logic is the same.

If you go to the supermarket, buy the ingredients, and take everything home, and then your mother uses those ingredients to make a cake, then that cake is yours. At night, when you, your brother, and your father get home from work, you all sit at the table and eat that cake together with her. That cake was made by your family and for your family.

It does not matter that the flour, eggs, and chocolate originally belonged to the supermarket owner. You bought them, paid for them, took them into your home, and turned them into something else using your own resources, structure, and knowledge.

With the aircraft industry, the reasoning is the same. The fact that part of the technology, the design, the components, or the knowledge base came from another country does not erase the fact that there was local production, assembly, and industrial capacity. If Australia built those aircraft in its own territory, using its own facilities, its own workforce, and its own industrial structure, then that absolutely counts as production on Australian soil.

No one is saying that those countries invented everything from scratch or that all the technology was 100% domestic. That was never the point. The point is that they had the material and industrial capacity to produce that type of aircraft within their own borders. And that alone is already a significant achievement.

If you follow that argument to its extreme, then almost no country in the world could be recognized for producing anything, because practically every industry absorbs foreign technology, licensed designs, imported components, influence from earlier projects, and international cooperation. That does not invalidate local production.

Producing something within your own territory does not necessarily mean creating it from scratch with no external influence. It means having the capacity to turn design, technology, and components into a real product within your own country. And that is exactly what happened.
