WASHINGTON (NNS) -- The Navy concluded a successful light-off test of its upgraded Periscope Detection and Discrimination (PDD) capability for the AN/SPQ-9B Anti-Ship Missile Defense Radar aboard USS Lake Champlain (CG 57), March 12.

The upgraded PDD capability represents a noteworthy improvement in submarine detection in support of the Navy's overall anti-surface warfare efforts.

Champlain is currently conducting live-fire testing off the coast of California with its 5-inch guns to verify the new mode on the SPQ-9B while the crew undergoes operator training to ensure proficiency with the new capability.

"Our men and women have worked so hard to develop the technology for this key capability," said Rear Adm. Jon A. Hill, program executive officer for Integrated Warfare Systems (PEO IWS). "We are eager to move forward with delivery of this upgrade to the fleet to improve their warfighting capability."

In December 2015, the Navy awarded a contract for AN/SPQ-9B production to Northrop Grumman to provide radar systems with the PDD mode to DDG 51-Class Destroyers.

"This award was a huge milestone for our SPQ-9B team," said Capt. Seiko Okano, SPQ-9B program manager. "The Navy is counting on us to deliver this vital system on schedule and this contract award keeps us on track to do exactly that."

The delivery of this capability represents the culmination of almost a decade of Navy investment in developing a periscope detection mode for the AN/SPQ-9B Radar and the collaborative efforts of NAVSEA agencies, Office of Naval Research, the Naval Research Laboratory, and Naval Surface and Expeditionary Warfare Command.

PEO IWS is an affiliated Program Executive Office of the Naval Sea Systems Command. IWS is responsible for spearheading surface ship and submarine combat technologies and systems, and for implementing Navy enterprise solutions across ship platforms.
