Description

THIS SOURCES SOUGHT IS FOR INFORMATIONAL PURPOSES ONLY. THIS IS NOT A REQUEST FOR PROPOSAL. IT DOES NOT CONSTITUTE A SOLICITATION AND SHALL NOT BE CONSTRUED AS A COMMITMENT BY THE GOVERNMENT. RESPONSES IN ANY FORM ARE NOT OFFERS, AND THE GOVERNMENT IS UNDER NO OBLIGATION TO AWARD A CONTRACT AS A RESULT OF THIS ANNOUNCEMENT. NO FUNDS ARE AVAILABLE TO PAY FOR PREPARATION OF RESPONSES TO THIS ANNOUNCEMENT. ANY INFORMATION SUBMITTED BY RESPONDENTS TO THIS TECHNICAL DESCRIPTION IS STRICTLY VOLUNTARY. ALL CAPABLE COMPANIES ARE ENCOURAGED TO RESPOND, REGARDLESS OF SIZE. Introduction: The Department of the Navy, Naval Air Systems Command (NAVAIR), on behalf of Program Executive Office Tactical Aircraft Programs and Program Manager, Air (PMA-265), is conducting market research to identify interested and capable sources that may be able to support a potential future effort related to the AN/APX-111(V) Combined Interrogator-Transponder (CIT) Redesign. This notice is issued solely to conduct market research and for planning purposes only. The AN/APX-111(V) CIT provides Mark XIIB Identification Friend or Foe (IFF) interrogator functionality, supporting autonomous, beyond-visual-range positive identification and fratricide risk reduction for tactical aircraft operations. Its transponder function supports applicable civil and military air traffic control requirements. The current system relies on the KIV-78 cryptographic applique for secure Mode-5 capability. The existing Receiver-Transmitter configuration is affected by hardware Diminishing Manufacturing Sources and Material Shortages (DMSMS) issues that threaten long-term readiness and sustainment. To address these issues, PMA-265 is assessing industry capability to support a redesign of the RT-1763/APX-111(V) Receiver-Transmitter and associated activities necessary to maintain operational relevance and support continued integration on F/A-18E/F and EA-18G aircraft. The redesign is expected to include forward-compatible provisions for future cryptographic modernization, including accommodation of the KIV-78A effort and potential future KIV-78 variants compliant with newer security requirements. PMA-265 is responsible for the CIT Redesign effort. The contemplated redesign effort is expected to consider structural and interface provisions for future cryptographic updates, qualification, integration, testing, radio frequency spectrum certification, Department of Defense (DoD) Air Traffic Control Radar Beacon System Identification Friend or Foe Mark XIIB System (AIMS) certification, Communication Navigation Surveillance/Air Traffic Management (CNS/ATM) certification, and limited Operational Flight Program administrative updates, as applicable. The Government seeks information on industry capability to support a solution that sustains readiness, survivability, secure combat identification, and future compliance without creating a capability gap. The objective of this market research effort is to identify vendors with the technical capability, production capacity, certification experience, integration expertise, repair capability, and long-term sustainment capability to support a potential future effort for the AN/APX-111(V) CIT Redesign and lifecycle support, including Avionics Redesign, Form-Fit-Function-Interface (FFFI) replacement development, prototype and engineering services, qualification and certification, F/A-18E/F and EA-18G platform integration, new production, repair, spares, and sustainment through end of service life.
