I try and recognize when a ship, sub, or other missing vessel has been found, especially if it has been missing for a long time. I saw this on Wikipedia today – https://en.wikipedia.org/wiki/French_submarine_Minerve_(S647).
Here are several articles reporting on the sub:

YouTube (search): https://www.youtube.com/results?search_query=La+Minerve+found+2019
Between the various news reports and articles I read, it appears the sub may have been lost to weather, and based on seismic activity, it likely imploded once it exceeded its depth limit.
