DOT&E warns on DDG 1000 self-defence capability

10 February 2020

Test events conducted on the US Navy's (USN's) Self-Defense Test Ship (SDTS) have revealed significant problems affecting the ship self-defence capability of the new DDG 1000 Zumwalt-class destroyer, according to the Pentagon's Director, Operational Test and Evaluation (DOT&E).

The poor results to date have forced the navy to suspend the test programme while the root cause of the problems is identified. In the meantime, there is a risk that key command and sensor equipment will be removed from the one-of-a-kind SDTS asset before the live-fire test programme completes.

Three DDG 1000 Zumwalt-class ships are being built for the USN, with the first, USS Zumwalt , currently completing combat system activation activities.
