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. The results of this Sources Sought RFI will be utilized to determine if the required product or service exists in the marketplace and if any Small Business (SB) Set-Aside opportunities exist. All SB Set-Asides for small business concerns will be considered per FAR 19.104-1(e). Key Requirements and Recommendations for Interested Businesses: System for Award Management (SAM): To be eligible for government contracts, your business must be registered in the SAM database at https//:sam.gov/. You do not need to be registered to respond to this notice, but you will need to be registered if NAVAIR decides to request proposals and award a contract. Small Businesses (SB): To assist in our market research and determination of any applicable SB set asides for this effort, please address the following as appropriate: Identify your business’ CAGE code and Unique Entity Identifier (UEI). Identify if your business is considered small under the size standard associated with the North American Industry Classification System (NAICS) for this effort. Identify your business’ socio-economic status (Please list all applicable designations and indicate which are officially SBA-certified: Women-Owned Small Business (WOSB), Economically Disadvantaged Women-Owned Small Business (EDWOSB), Service-Disabled Veteran-Owned Small Business (SDVOSB), HUBZone, Small Disadvantaged Business) SDB, 8(a)). Note: To be considered for a targeted socio-economic Small Business Set-Aside (HUBZone, SDVOSB, WOSB, or 8(a)) as a Prime Contractor, your firm must possess an active Small Business Administration (SBA) official certification in the Dynamic Small Business Search (DSBS) / SAM.gov. Self-certification is not sufficient for set-aside prime awards under these programs. Address if your SB is interested in participating as a prime or subcontractor. If your SB is interested in the prime contractor role: Identify anticipated teaming partners by name and their role in the overall acquisition (provide each partner’s CAGE Code, size and status of the partner, approximate workshare, and specific capabilities/solutions that partner brings to the acquisition, etc.). If your SB plans to utilize “similarly situated entities” to meet the Limitations on Subcontracting, identify the name & CAGE Code of the specific firm(s) you intend to partner/subcontract with to meet the requirements as well as their SB size status under the NAICS that you as the prime would assign for their workshare. Information regarding any planned similarly situated entity should be included in answering any questions outlined in this Sources Sought Notice (SS-N) in order to assist the Government’s capability determination. SB’s that have not worked with the U.S. government or NAVAIR before are encouraged to visit the NAVAIR Office of Small Business Programs (OSBP) website at https://www.navair.navy.mil/osbp/. It is also recommended to review the Federal Acquisition Regulation (FAR) Part 19 Small Business and FAR Clause 52.219-14 Limitations on Subcontracting (https://www.acquisition.gov), which covers SB programs. Partnership and Feedback: NAVAIR encourages all interested companies to respond. Market research and industry feedback are essential to the acquisition process and assist the Government’s capability determination. The information you provide will be used for internal decision-making at NAVAIR and may be shared within the Government support team for market research purposes. Confidentiality: It is your responsibility to ensure that you are not violating any confidentiality agreements by providing the requested information. Proprietary Information, if any, should be clearly marked. The Government will use reasonable efforts to protect properly marked Proprietary Information in accordance with applicable law and regulations. Submission Details: Capability Statement Requirements: Your business' response must be a comprehensive package that demonstrates your ability to provide the requested AN/APX-111(V) CIT Redesign and Lifecycle support. Responses should be specific, practical, and tailored to the contemplated effort. Marketing materials alone are not sufficient. The Government requests that respondents clearly identify which portions of the effort they are capable of performing directly and which portions would require subcontractors, teammates, or Government support. Responses should, at a minimum, include the following: Business name, CAGE code, and UEI Business size and socioeconomic status OEM status Place(s) of Performance, manufacturing location(s), and repair location(s) (if different) Facility clearance level, if any Primary technical Point(s) Of Contact (POC) Major teammates or subcontractors Active corporate quality management system certifications and relevant technical process standards Technical capability summary Relevant experience and past performance summary Production capability summary Repair capability summary Certification and integration experience summary Technical data/intellectual property position Cybersecurity/export control posture Schedule assumptions Major risks and mitigation approach Recommended acquisition approach SB participation or teaming concept Formatting and General Guidelines: Requirement & Specifications Page Limit: 10 pages maximum, excluding a cover page and administrative identifiers.
