JDAMs are cheap. They come in a few varieties and they work. You can load up a B- (fill in the blank 1, 2, 52) with a bunch of these things, go loiter for hours and effectively take out a lot of patrol boats or larger. This fills a valid need that carrier-based aviation cannot provide. They can do a lot of things, but are limited by the size of aircraft. This is a win in my book.
