Today, ships (and other objects of similar size) are sometimes sunk to help form artificial reefs, as was done with the former USS Oriskany in 2006. It is also common for military organizations to use old ships as targets, in war games, or for various other experiments. As an example, the decommissioned aircraft carrier USS America was subjected to surface and underwater explosions in 2005 as part of classified research to help design the next generation of carriers (the Gerald R. Ford class), before being sunk with demolition charges.
