Remember that Argentinean diesel-electrical TR-1700 that sunk while back? Seems it kind of fell off the radar of everyone. It still hasn't been found.
What the public knows:
>It reported a battery fire three days earlier due to water spilling into its snorkel. Was extinguished and battery disconnected
>Had a history of maintenance problems
>Was carrying no live weapons on board
>It sunk.
>Loud transient detected on numerous public and private hydrophones
>Cross bearing (pic 2) released. Despite having those exact coordinates, the sub isn't there. The issue is that it could have and probably did sink on a deep and steep part of the continental shelf, so it could technically be anywhere from 100 meters under to 1,000+, way past its crush depth (pic 4).
>Sonogram of said transient released (pic 3). The bottom frequency is in line with an organic and is possibly a false correlation. Also seems deliberately hard to read, the timescale and time window given is very odd.
>Event 1, the big red spike, is clearly not a torpedo impact (which would be shortish spike, noticeable pause, very big spike, high noise afterwards) and more in line with an implosion or very sudden explosion.
>Event 2, the 20-ish second long one afterward, is likely an emergency blow of the main ballast tank. Could also be a compartment bursting, but that typically has a different and shorter profile.
>No real speculation on the couple fainter events afterwards. Maybe secondary explosions or compartments bursting.
Anyone have some insider knowledge on this kind of stuff? What do you guys think happened?
