The Navy awarded Northrop Grumman a cost-only modification valued at $9 million related to its work on a portion of the Navy’s premier electronic warfare system.

The award relates to Block 3 of the Surface Electronic Warfare Improvement Program, or SEWIP Block 3, provides ships a scalable electronic warfare enterprise suite with improved electronic attack capabilities.

Last year, the Department of Defense’s Inspector General’s office found that the $5.7 billion SEWIP was experiencing significant cost overruns that could put the program behind schedule.

Though much of the specific amounts were redacted, the report called the overruns “significant increases” over the budget for the engineering and manufacturing development phase of SEWIP Block 3.

Naval Sea Systems Command on Feb. 12, 2015, awarded the SEWIP Block 3 design and development contract to Northrop Grumman with an option for the EMD phase originally valued at $91.7 million.
