invested in in the last few years. these are $250 million each. the government spent over $32 billion just in the last few years implementing this poseidon program. it s very valuable. it s looking for submarines. that s what it s designed for, among other things. when you re looking for a submarine, you ve used as much spread as you can. it s like taking this airplane and expanding the width to as far as the drones can fly, coordinating that information and back to see what the results of the drone search is. more of an argument for more assets. the more you have doing it, the better you can be. the last thing you want in this grid is to have another airplane flying over and confusing things. have you to have a centralized location. as david pointed out, you re clearing an area. clearing is we know it s not here. so as this progress less in each area actually helps the search. more is not necessarily better. that s correct. david funk, thank you very much for joining us.
