Description
DD(X) will have a "tumblehome" hull form, i.e. a design in which hull slopes inward from above the waterline. This will significantly reduce the radar cross section since such a slope returns a much less defined radar image rather than a more hard-angled hull form. Requirements for the Integrated Deckhouse EDM is that it is fully EMC (Electromagetic Compatibility) shielded with reduced infrared and radar signatures. Measures to fulfil these conditions include an all-composite superstructure, low signature electronically steered arrays, an integrated multi-function mast and low radar and infrared signatures. Other measures to reduce the vessel's infrared signature include the development of an exhaust suppressor. Harris Corporation has been awarded a contract for the development of the Common Data Link (CDL) X/Ku-band phased array antenna systems, which will be integrated into the Integrated Deckhouse Assembly. The multi-beam electronically-steered antenna will allow connectivity with up to eight CDL terminals. The DD(X) is planned to have a displacement of around 12,000t, less than the 14,000t or more of the DD-21, with a sustained speed of around 30 knots.
