The Department of Defense, through the Naval Air Systems Command (NAVAIR), is seeking to award a modification to the existing Engineering and Manufacturing Development (EMD) contract N0001920C0041 for the AN/AAQ-45 Distributed Aperture Infrared Countermeasure (DAIRCM) Laser 2. This modification aims to update the Non-Recurring Engineering (NRE) scope to include Laser 2, which involves the development of Production Representative Models (PRMs) and prototypes for system qualification and testing. The procurement is critical as it pertains to electronic countermeasures, with DRS Systems, Inc. being the sole source for this requirement due to proprietary data and design ownership. Interested parties must direct inquiries to Contract Specialist Sarah Willis at sarah.m.willis10.civ@us.navy.mil, with responses due by February 14, 2025, as this is not a request for proposals and no contract will be awarded based on responses to this notice.
