Some help. please, understanding France's anger over the U.S./Australian sub deal

[crickets]

24. Politics, timing, and cost overruns.

Australia wanted to keep sub construction in Australia, which was costlier and contributed to delays. France's Naval Group won the contract for the sub build, but the project was again delayed by a request for an extension. Concerns about the situation, as well as rumblings about pulling out of the agreement with France, have been going on for years. This is not the quite the big surprise France is claiming, but it could have been handled better.

Why Did the Deal with Naval Group Collapse?

Australia’s Ministry of Defence recommended three contenders for the competitive evaluation process, and it picked French shipbuilder Naval Group as the eventual winner. The company won the Collins-class replacement program, also known as SEA1000, in 2016 with its Shortfin Barracuda Block 1A design. This conventionally powered diesel-electric submarine is based on a scaled-down version of the nuclear-powered Barracuda (Suffren) design that is now entering French Navy service.

The Australian media have long been reporting citing sources in the Defence Ministry that the deal with Naval Group to build a dozen submarines for the Navy was not making progress.

It is said to be due to a combination of reasons, including cost blowouts, missed delays and political. Since negotiations with France began, Australia has had three prime ministers, three deputy PMs, three failed treasurers, five defence ministers and four ministers for defence industry. Of the 15 individuals to have held these portfolios, seven have left the Parliament.

While the project was initially estimated to cost between $20-25 billion, it is now reportedly pegged at around $65 billion (AUS$90 billion). France, meanwhile, is said to be paying $10.2 billion for six Barracudas for its own Navy.

Even the idea of building a submarine powered by a diesel-electric engine was considered a fail.
