The Department of Defense, through the Naval Sea Systems Command (NAVSEA), intends to modify an existing contract with Northrop Grumman Systems Corporation for additional engineering support related to the SEWIP Block 3 program for fiscal years 2026-2027. The modification will involve an additional 240,000 hours of Cost-Plus-Fixed-Fee Level-of-Effort and Cost Only contract line items, aimed at enhancing the design agent engineering support without extending the current contract's period of performance. This procurement is critical for maintaining and advancing the capabilities of electronic countermeasures and related systems, which are vital for naval operations. Interested parties may submit capability statements or proposals within 15 days of this notice, and should direct inquiries to Ryan Brophy or Matthew Brimmer at the provided contact information.
