Sub Brief has a video out on the French Suffren (Barracuda SSN variant) submarine class.
Key points discussed are long development time, very useful ISR capabilities in sail masts, remarkable new sonar performance (Thales UMG 3000), new torpedo (F21) and relationship with Blackfin Barracuda (SSK version). THere is no mention of the recent sale to the Dutch navy of the SSK version. Aaron seems to express some scepticism on the claimed sonar performance. Presumably, the new Thales sonar would not be worse performing than the Astute’s Type 2076, which is now over 20 years old.
For the record my personal view is that Australia should have switched from the Attack Class to this SSN instead of AUKUS. It is not a question fo which is the better submarine, which in my view is academic. The Virginia is excellent now and the SSN AUKUS will be excellent in the future. However from a practical procurement and constructibility viewpoint Virginia production is struggling to meet demand and SSN AUKUS production is too far away to avoid a capability gap. Suffrens may not be superior to either, but they only have to be better than Chinese and Russian subs, which on all reports they easily are in both stealth and sensors. We could have been building these now with different politics. Also the cost would have been dramatically less, to the point where some other DSR cuts might not have happened.
