The Department of Defense, specifically the Program Manager Ground Based Air Defense (PM GBAD) within the Department of the Navy, intends to negotiate a sole-source contract with Honeywell Aerospace for engineering and technical services related to the Honeywell Tactical Advanced Land Inertial Navigator (TALIN) system. The objective of this procurement is to configure the TALIN inertial navigation system to enhance capabilities for the Marine Air Defense Integrated System program, as Honeywell is the original designer and producer of the system, making it the only viable source for these services. This acquisition is critical for meeting the specific performance and design requirements of the PM GBAD, with a Firm-Fixed-Price contract anticipated for a one-year period. Interested parties may express their interest and capability by submitting information to Mr. Stephen Cunningham and Ms. Stasia Baker via email by 12:00 PM Eastern Daylight Time on May 9, 2025, although no formal solicitation package will be available.
