Destroyers Maxed Out, Navy Looks To New Hulls: Power For Radars & Lasers

The Navy has crammed as much electronics as it can into its new DDG-51 Flight III destroyers now beginning construction, Rear Adm. William Galinis said this morning. That drives the service towards a new Large Surface Combatant that can comfortably accommodate the same high-powered radars, as well as future weapons such as lasers, on either a modified DDG-51 hull or an entirely new design.

William Galinis “It’s going to be more of an evolutionary approach as we migrate from the DDG-51 Flight IIIs to the Large Surface Combatant,” said Galinis, the Navy’s Program Executive Officer for Ships. (LSC evolved from the Future Surface Combatant concept and will serve along a new frigate and unmanned surface vessels). “(We) start with a DDG-51 flight III combat system and we build off of that, probably bringing in a new HME (Hull, Mechanical, & Engineering) infrastructure, a new power architecture, to support that system as it then evolves going forward.” “Before the end of the year, we’ll start reaching out to industry to start sharing some of the thoughts we have and where we think we’re going,” Galinis told a Navy League breakfast audience. “We’ll bring industry into this at the right point, but we’re still kind of working a lot of the technology pieces and what the requirements are right now.” Aegis cruisers and destroyers. Evolution, Not Revolution This evolutionary approach is similar to how the current Aegis combat system entered service on the CG-47 Ticonderoga cruisers in 1983 but came into its own on the DDG-51 Arleigh Burke destroyers. (Despite the difference in names, the two classes are virtually the same size). The DDG-51 is now the single most common type in the fleet, a vital part of the hoped-for 355-ship Navy, with some ships expected to serve into the 2070s: There are now 64 Arleigh Burkes of various sub-types in service; nine of the latest Flight IIA variant are in various stages of construction; and work is beginning on the new Flight IIIs in Mississippi (Huntington Ingalls Industries) and Maine (General Dynamics-owned Bath Iron Works). Navy photo The USS McCain (DDG 56) The Navy is doubling down on long-standing programs to keep its older warships up to date and on par with the newest versions. But the current destroyers just won’t be able to keep up with the Flight III, which will have a slightly modified hull and higher-voltage electricity to accommodate Raytheon’s massive new Air & Missile Defense Radar. A stripped down version of the AMDR, the Enterprise Air Search Radar (EASR, also by Raytheon) is already going on amphibious ships and might just fit on older Burkes as well, however.
