Reported to be in three major sections in a debris field that measures about 260 X 330 feet: the aft section of the sub including its propeller, the sail, and a large (82-foot) forward section. Sections badly deformed by pressure.
The report correctly concludes the relatvely small size of the debris field indicates collapse occurred close to the sea floor. From the CTBTO acoustic data we know the collapse depth was 1536 feet. The depth at the wreck-site is reported to be 3040-feet.
There is still some confusion over the source of the acoustic signal. It is being reported as a hydrogen explosion. Actually, it was collapse. The hydrogen explosion was not acoustically detected.
