No French SSNs for Australia Possible: Part Two.

France has never promised to export already developed SSNs (Suffren-class or otherwise) to Australia. The suggestion of retired submarine specialist and a past president of the Submarine Institute of Australia, Peter Briggs, https://www.aspistrategist.org.au/aukus-risks-are-piling-up-australia-must-prepare-to-build-french-ssns-instead/ cannot be met due to France's "no SSN export policy" and industrial limitations (see Part One of February 4, 2025). 

A. When, in 2016, Australia was seeking a "regionally superior submarine" which would have needed many characteristics of an SSN, DCNS (now Naval Group's) Chief Executive Herve Guillou ambiguously told AAP on March 24, 2016:

"“If, in 2050, Australia wants a nuclear submarine, they [France? or Australia with French assistance?] can design a nuclear submarine”  see https://web.archive.org/web/20160403082949/http://indaily.com.au/news/2016/03/24/france-pitches-nuke-sub-option-for-australia/ In 2016 and to this day French government owned Naval Group (NG) made no offer to export an SSN to Australia.

It may be no coincidence that France's completion year for its fourth and final 3rd generation SSBN is 2050. France's single nuclear sub assembly might then be available for new business which would include the SSN successor class to the Suffrens. https://en.wikipedia.org/wiki/SNLE_3G#Design_and_operation

Naval Group's ambiguous offer from 2050 to help design an SSN for Australia is later than the UK's offer to joint  design (with the US and Australia) the SSN-AUKUS from the late 2030s and build SSN-AUKUS from the early 2040s. https://en.wikipedia.org/wiki/SSN-AUKUS . 

B.  Moving from ambiguous Naval Group commercial spin in 2016 - to a higher authority, French President Macron said in 2022, SSNs should not be sold to Australia. 

Macron said the sale of nuclear submarines to Australia “risks increasing tensions with China and make Australia dependent on other countries.” See https://see.news/macron-warns-australias-nuclear-subs-deal-will-not-deliver of 18 November 2022.

C.  Whether nuclear submarines use HEU (like the US and UK) or LEU (like France) France's opposition to exporting SSNs to Australia still holds. This is because of French concern over offending China. 

Another reason is French unwillingness to risk its most sensitive technical secrets.  Here is a 22 July 2022 Australian academic's comment:

 "The French government never has exported, or even permitted formal negotiations to export, the nuclear submarine technology it considers a crown jewel of its military. Exporting nuclear submarines would require a high level of bilateral trust, which Morrison shattered and Albanese would need to rebuild." 

Macron is still France's President and he has not altered France's no nuclear submarine exports to Australia policy. Even if France permitted SSN exports to Australia France's/NG's single nuclear submarine assembly line at Cherbourg can only cater for the French Navy's remaining Suffrens, then its new SSBNs, out to 2050.
