Federal Agency Name: Air Force Lifecycle Management Center, F-15 Directorate

(AFLCMC/WAQ)

REQUEST FOR INFORMATION: THIS IS NOT A SOLICITATION: This Request for Information (RFI) will be utilized in acquisition planning for Depot Activation capabilities to support the F-15 Program. This RFI does not constitute an Invitation for Bids (IFB), a Request for Proposal (RFP), or a Request for Quote (RFQ), nor does its issuance obligate or restrict the Government to an eventual acquisition approach. This RFI does not obligate the Government to issue a solicitation. This RFI is being conducted solely for information and planning purposes and does not constitute a solicitation. Neither unsolicited proposals nor any other kinds of offers will be considered in response to this request or accepted by the Government to form a binding contract. No solicitation document exists, and a formal solicitation may or may not be issued by the Government because of the responses to this RFI. The Government will not be liable for payment of any response preparation expenses and is not obligated by the information received.

Any costs incurred by interested companies in response to this announcement will NOT be reimbursed. The information provided may be used by the Department of the Air Force in developing future acquisition strategies. Interested parties are responsible for adequately marking proprietary or competition sensitive information contained in their response.

1. Background and Scope

The F-15EX program is a multi-role weapon system that leverages more than $5B of foreign military sales investment and capability enhancements on an even more robust F-15 airframe.

This new advanced fighter aircraft will be replacing the existing F-15C/D fleet and augment an aging F-15E fleet. This system will be core for the Air Force.

In accordance with Federal Acquisition Regulation (FAR) Part 10, the F-15 Program Office (AFLCMC/WAQ) is conducting market research to identify potential sources capable of fielding Depot Activation capabilities. Specifically, this RFI seeks insight on information towards developing a Long-Term Support Strategy to improve supply chain efficiencies, material availability and supplier base for multiple LRU’s and their subcomponents for all Original Equipment Manufacturers (OEMs). F-15EX will leverage to the max extent, when possible, to align with current F-15 sustainment. The plan is to utilize Key Performance Indicators to measure and incentivize awardee’s performance to meet critical goals in support of the warfighter mission.

2. Need Statement

Depot Activation is broadly defined in 10 USC Section 2460 as material maintenance or repair requiring the overhaul, upgrading, or rebuilding of parts, assemblies, or subassemblies, and the testing and reclamation of equipment as necessary. The objective of this depot activation program is to establish F-15EX organic maintenance capabilities while maximizing utilization of existing F-15 legacy assets. This contract will support Air Logistics Complex (ALC) stand-up through contractor identification of requirements and design/build/purchase of Specialized Test Equipment (STE), Test Program Sets (TPS), and Interface Test Adapters (ITAs) required for depot-level hardware testing and repair. The United States Air Force (USAF) will provide all Department of Defense (DoD) common support equipment for this activation effort. Due to proprietary restrictions on F-15/F-15EX Line Replaceable Units developed through private investment, complete technical data provision is limited by intellectual property rights, Last Time Buy (LTB) constraints, and licensing requirements for sensitive manufacturing processes and components.

This request for information focuses on the provision of the above-referenced Depot Activation capabilities for the F-15 EX’s current Priority Valve. The repair and maintenance of the Priority Valve requires not only the Priority Valve itself but all associated parts/spares and the rights in technical data necessary to maintain and ensure the software used in the displays functions correctly to support verification of repairs at designated ALC.

A Priority Valve is specialized, high-pressure, aerospace-grade, hydraulic control devices designed to ensure a steady, priority supply of fluid to critical sub-systems while diverting excess flow to secondary, non-essential systems. The valve automatically manage flow based on pressure demand. Priority Valve acts as a safety mechanism that shuts off or reduces flow to users if system pressure drops, ensuring high pressure, designed for demanding aerospace applications and are used in load-sensing systems to prioritize critical functions over other, less critical actuators. The Contractor’s plan for work will be coordinated through the F-15EX Depot Maintenance Activation Working Group (DMAWG). The Contractor’s plan shall focus on depot level repair work transitioned to Government organic depots. Additionally, the Contractor shall negotiate and implement required Partnering Agreements (PA) and Implementation Agreements (IA) between the Contractor, Original Equipment Manufacturer (OEM), and the Government as required. The Contractor shall provide transition planning that identifies areas that must be transitioned from contractor support, e.g. Interim Contractor Support (ICS) to Government support.

To facilitate the depot stand-up, the Contractor is expected to identify all necessary requirements, maximizing the utilization of existing F-15 legacy capabilities (equipment, testers) and documenting any discrepancies in required testing and repair processes unique to the respective Air Logistics Complex (ALC).

Government training and materials: The Contractor shall provide the USAF Maintenance

Technicians with training in the test and repair of all units under test to the piece part level with emphasis on parts requiring special processes and equipment. Training shall include operation, maintenance, and calibration (as applicable) of the STE. The training shall allow for USAF Maintenance Technicians to participate and complete the training within 30 days of final acceptance. The Contractor shall identify training facility requirements 6 months prior to training commencement.

This RFI seeks rapidly fieldable, producible, scalable Depot Activation. This includes access to the necessary hardware and software to enable the F-15E/EX.

3. Questions to Industry

The following questions aim to enhance the Government’s understanding of current industry capabilities, emerging innovations, and alternative approaches that may have been overlooked in developing an effective acquisition strategy.

Offerors should consider the recurring cost of hardware, the ease of installation or deployment, sustainment approach, and the rate at which solutions can be manufactured and fielded.

Respondents should assume close partnership with a government-led team to enable integration, interface development and architecture implementation.

1. The government is interested in industry input in developing the most efficient solution/capability to organically repair components related to Depot Activation.

2. The government is interested in a solution to address/resolve Technical Data (TD)/data rights/Intellectual Property (IP) rights.

3. The government is interested in cost, schedule and performance for components related to Depot Activation.

4. The government seeks the most efficient solution for contracting and is interested in what the Contractor has on contract with the DoD.

4. Responding to this RFI

This RFI invites respondents to submit an unclassified White Paper (CUI is acceptable) describing their system. In addition, respondents are encouraged to submit corporate overview information and basic qualifications in managing hardware and software development projects traditionally associated with Depot Activation as well as any such projects that are similar in scope. The Government intends to consider all Industry inputs and initiatives. The F-15 Program

Office plans to leverage industry recommendations on the delivery and performance of Depot Activation supplies and services to implement best practices, improve productivity, gain programmatic and operational efficiencies, and realize cost savings.
