 So we're conducting the inaugural RIMPAC 2016 submarine rescue tabletop exercise where we have several RIMPAC nations that have submarine and or submarine rescue capability. So this is part of a multi-stage event where we've done a symposium going over the different aspects of submarine rescue and right now we're doing a practical exercise. This whole exercise is to show that different countries can rescue personnel out of different countries' submarines. Their rescue asset is going down right now to simulate hooking up to the submarine that's stricken and sitting on the bottom to evacuate the people out of it to bring them back up to safety. So we're taking that learned information and translated it into how do you actually do it, the command and control, the processes, the decision making and how that would look for real and the more we practice it now the better off it will be when we actually have to execute such an event.
