from the link: >A 10,000-pound explosive charge was set off about a hundred yards from the Jackson – the Navy wouldn't say exactly how close, saying the actual distance is classified and they provided the photo clearly allowing for the precise calculation :) - the explosion is about 12 widths of the helicopter deck from the ship and that means at least 200-250m which sounds more realistic as setting off a 5ton explosion 100m from a small aluminum ship - who is going to pay for all that damage :) If the test is officially declared for anything close to 100m then that may be another case of "Pentagon Wars" ...
