APX-119 Identification of Friend or Foe (IFF) Transponder

Solicitation FA852526RB012 is a firm-fixed-price request for the procurement of APX-119 Identification of Friend or Foe (IFF) Transponder software licenses for the C-5M Super Galaxy fleet. Managed by the Department of Defense through the AFLCMC WLSKA at Robins AFB, Georgia, the primary objective is to implement a software upgrade that enables Traffic Collision Avoidance System (TCAS) capabilities while selectively inhibiting position reporting systems to reduce aircraft movement signatures during worldwide operations. The government intends to purchase 60 proprietary software licenses from Raytheon, as the original equipment manufacturer is considered high risk for alternate vendors. The contractor is responsible for compiling, delivering, and maintaining the L4 executable software application, along with critical technical data including software version descriptions, release notes, and installation procedures. Deliverables must be submitted electronically via the Multi-user ECP Automated Review System and physically via two encrypted optical discs to Robins AFB within 60 days of contract award. The contractor must provide comprehensive technical support during the government acceptance period and adhere to strict cybersecurity and quality standards, including DFARS 252.204-7012, NIST SP 800-171 Rev 3, and military airworthiness certification processes such as MIL-HDBK-516C.
