Zumwalt: The Navy's massive, high-tech destroyer is here

Big ship, low profile

The absence of high-profile masts and rotating antennas, combined with a composite-material deckhouse, means the Zumwalt-class destroyer will be extremely low profile.
Water sleeting along the sides, along with passive cool air induction, also reduce signature thermal emissions, and although it's almost 40 percent larger than a current Arleigh Burke-class destroyer, the radar signature will be more like that of a simple fishing boat than a menacing military machine.
