They were aware there were issues, and negotiations happened on how to fix them, with the French leaving them with the impression everything is good. Meanwhile Australia was already negotiating an alternative deal.

The French culture is to never deliver bad news before the deadline has arrived. Underlings will never tell their boss that something is impossible, decisions will be made by grande-ecole-bosses without technical expertise and relationships are valued far higher than knowledge and expertise. You'll always get the first impression that all is well and they'll manage before the deadline. If you need a real non-sugar-coated insight as to how the project is going you need to gather your own data. Discreetly.
However, as soon as shit has hit the fan and bosses got involved, they'll bend over backwards to make things work. But you cannot expect meeting the first deadline, ever. Same for the first budget. Subsequent ones depend on the size of the project.

No, it definitely is not. You have no idea of how this kind of project works.
Naval Group has a ton of experience managing large contracts with state actors. They have worked with Saudi Arabia, the UAE, Singapore, Taiwan, Pakistan, India, Malaysia, Egypt and I am probably forgetting some. They know what they are doing.
