15 Miles deep, no way!
If it was 15 miles (24.14 Kilometers) deep then no known submersible sub can dive that deep to retrieve the black box, however the average depth of the Indian ocean is 3,890 meters with the deepest point being the Diamantina Deep in the Diamantina Trench at 8,047 meters.
The Diamantina Trench should pose no problem as I believe it is further south of the search zone.
Out of interest the deepest diving submersible craft is the Mir 1 & Mir 2 which can dive to a maximum depth of 6,000 meters (6 Kilometers) & there is only 7 diving submersible craft that can go down to between 3,000 meters to 6,000 meters in the world.
