Interesting facts: Tomahawk is today the US's top-of-the-line operational long range weapon for land attack. Currently in development is the replacement, named Tactical Tomahawk (TACTOM), which will feature in-flight retargeting, loitering capability (talk about a diplomatic tool!), enhanced navigation capabilities, at less than half the cost of the currently planned block IV variant.
