 Last year we celebrated 100 years of mateship. That's 100 years of the US and Australia fighting side-by-side and the submarine a strategic force is just one of the cornerstones of both our navies. You visit as I have done HMAS Sterling, the naval base on the West Coast. You'll have US personnel clamoring off those submarines. I think it's a force multiplier. We have six members here from the US Navy. That collaboration is just extending that mateship. Coming down here and operating with them you become instantaneously part of their family and part of their force. Basically an extension of the larger Navy family just operating with a different country on a slightly different platform. They do a lot of training here just like we do. We go under way, we do drills, we keep everything so that if there's a situation the submarines can handle that situation to the best of their ability quickly efficiently and smoothly. It really helps with just understanding tactics because not only do I learn the Australian tactics and how they operate as a sub force and how they operate as a diesel boat force but it also helps them understand the American tactics. I think it has definitely given me a lot of respect for what other countries and other navies do. You know like the old walk and mile in someone else's shoes like I am literally doing that right now. The most professional development you could ever get is just seeing literally how another country and another nation and another class type you know diesel versus nuclear operates so it's been it's been great. I can't stress enough how good it is having exchange programs so it's a pleasure having them work with me in Western Australia here.
