  10. Logistics Support


Lockheed Martin has successfully completed these replacements and enhancements for our customers and have extended the life of their radars well beyond the original designed life expectancy.



*Performance Enhancements (PE) – Enhancements allow reliable performance in more challenging environments.  LM continually adds performance improvement features to an already robust set of FPS-117 and TPS-77 upgrades. We developed features based on prior customer needs, and leverage more than 25 years of LM investments in the continuous improvement of radar technology. LM’s commitment to making steady internal Research and Development (IRAD) investment in the product enable features to be available for little or no Non-Recurring Engineering (NRE) customer investments.


** Reliability & Maintainability (RM) – Enhancements relate to maintain & replacement for existing hardware. New equipment offers improved reliability at the Line Replaceable Unit (LRU), assembly, and system level, resulting in increased Operational Availability (Ao). Operations and maintenance organizations can reduce their maintenance actions and enhance overall depot supportability.



If you do not find the enhancement you are looking for, we can customize to meet your request.
