The Department of Defense, through the Naval Information Warfare Systems Command (NAVWAR), intends to modify a sole source contract (N00039-17-D-0004) to increase the ceiling for the Environmental Satellite Receiver Processor (ESRP) procurement. This modification will support the continued procurement of specialized technical, engineering, and sustainment services, as well as hardware, including up to five Engineering Development Models (EDM) of the modernized AN/SMQ-11 variant, provided by Vertex Modernization and Sustainment (V2X), the Original Equipment Manufacturer (OEM). The ESRP program is critical for delivering real-time environmental data to support mission planning and execution across various warfare areas. Interested vendors with the necessary expertise and capabilities are invited to submit their statements of capabilities within 15 calendar days of this notice, and inquiries should be directed to Tyler Joworski at tyler.j.joworski.civ@us.navy.mil or Julie Ward at julie.a.ward38.civ@us.navy.mil.
