Third Generation Forward Looking Infrared (3GEN FLIR) B-Kit

1. Introduction and Purpose

The Army Contracting Command-Aberdeen Proving Ground (ACC-APG) Belvoir Division is conducting market research on behalf of the US Army Product Manager Ground Sensors, in accordance with Federal Acquisition Regulation (FAR) Part 10.

The purpose of this market research has three objectives:

1. To identify potential sources that have the skills, experience, knowledge, and capabilities required to manufacture and deliver Third Generation Forward Looking Infrared (3GEN FLIR) B-Kits.
2. To identify and assess innovative acquisition strategies and business models that can significantly reduce the Government's total lifecycle cost for the B-Kit. The Government is specifically interested in solutions that address the challenges of high unit costs associated with small annual procurements and the long-term risks of component obsolescence. This includes, but is not limited to, solutions involving third-party financing, vendor-managed inventory, and large-scale bulk purchasing arrangements.
3. To identify potential sources capable of serving as a second-source provider to complete the design, development, qualification, and production of the 3GEN FLIR B-Kit.

This RFI is intended to gather information that will inform a follow-on acquisition strategy for both Low-Rate Initial Production (LRIP) and Full Rate Production (FRP) quantities.

2. System Description

The 3GEN FLIR B-Kit comprises a set of common assemblies, including the Dewar Cooler Bench (DCB) (provided as Government Furnished Equipment (GFE), optics (afocal, imager), and circuit card assemblies (CCAs). The B-Kit optics collect radiation in the Mid-Wave (MW) and Long-Wave (LW) infrared bands across four fields of view and focuses it onto a staring Focal Plane Array housed in the DCB. The B-Kit components are intended to be interchangeable Shop Replaceable Units. The 3GEN FLIR B-Kit provides the ability to detect threats at greater distances under a full spectrum of conflict and battlefield conditions. 3GEN FLIR enhances the platform's effectiveness and survivability by providing greater situational awareness promoting combat effectiveness and reducing fratricide. The B-Kit is also integrated into the Thermal Receiver Unit (TRU) as a sub-assembly which includes a Personality Module CCA, Electromagnetic Interference Filter, afocal guard, and electrical flexes mounted in the TRU mechanical bench.

The TRU, B-Kit sub-assemblies, electronic modules, and the DCB, defined under RFI # W909MY-22-C-0023, will be integrated into sight systems for subsequent integration onto host vehicle platforms. The B-Kit provider will be responsible for integrating the GFE DCB into their B-Kit design. The DCB will be provided as GFE to the B-Kit provider for final integration and testing. The B-Kit and TRU components are currently defined by the following technical documents:

• MIL-PRF-A3381791 - 3GEN FLIR B-Kit Performance Specification Low-Rate Initial Production (LRIP)
• MIL-PRF-A3381789 - CPS FDE Performance Specification LRIP
• MIL-PRF-A3381787 – Performance Specification for the 3GEN FLIR Thermal Receiver Unit (TRU) LRIP
• MIL-PRF-A3381783 - 3GEN FLIR Dewar Cooler Bench (DCB) Mechanical Drawing
• A3315467 - CPS FLIR Design Envelope Drawing
• A3381792 - 3GEN FLIR B-Kit Interface Control Document LRIP
• A3347070 - Interface Control Document for the 3GEN FLIR Thermal Receiver Unit (TRU)
• A3381780 - Interface Control Drawing, Thermal Receiver Unit, 3GEN FLIR
• MIL-PRF-A3381785 - Performance Specification for the DCB LRIP
• MIL-PRF-A3381784 - DCB Interface Control Document (ICD) LRIP

3.  Qualification and Technical Responsiveness Criteria

To be considered a responsive source for this market research, interested parties must demonstrate a viable path to providing a fully qualified B-Kit and TRU that meets all requirements in the technical documents defined above. Respondents can demonstrate this capability in one of three ways:

  a.  As a Manufacturer: The source must demonstrate it possesses a fully qualified B-Kit and TRU design that has completed a final System Verification Review (SVR) and Functional Configuration Audit (FCA) or provide data verifying its design meets all performance requirements.

OR

  b.  As a Solution Provider: The source must provide a detailed plan and verifiable evidence of its ability to acquire and deliver a fully qualified B-Kit and TRU from a qualified manufacturer. This includes, but is not limited to, letters of intent, teaming agreements, or other documentation demonstrating an established business relationship with the OEM or other qualified source.

OR

  c.  As a Second Source Provider: The source must demonstrate the technical expertise to design and qualify a 3GEN B-Kit. The respondent must detail its plan to complete the design phase, development phase including the timeline for technical reviews (CDR, TRR, SVR, FCA, and PRR), produce prototype units, achieve full qualification, and manufacture B-Kits and TRUs for LRIP and FRP.

4.  Technical Documentation and Security Requirements

The documents listed above are Distribution D restricted. The documents are authorized for use by the Department of Defense (DoD) and U.S. DoD contractors only. These documents also contain technical data whose export is restricted by the Arms Export Control Act (Title 22, U.S.C., Sec 2751, et seq.) or the Export Administration Act of 1979 (Title 50, U.S.C., App. 2401 et seq.), as amended. Violations of these export laws are subject to severe criminal penalties. These documents will be disseminated in accordance with provisions of DoD Directive 5230.25.

Companies or organizations may request copies of these documents by providing their Point of Contact information listed below to Jennifer Heath at contact@example.gov and must clearly state if and how they meet the conditions under which they can receive the documents referenced above. In addition, companies requesting the above information must register for an account with an internet accessible portal known as the Corporate Management System Online (CMS II). Registrants will access the CMS II website (https://www.mycmsportal.com) and follow instructions to complete registration. Documents are currently available for viewing in the CMS II under the 3GEN FLIR folder so the registrants must specifically request access to only the 3GEN FLIR folder. Access to the 3GEN FLIR folder documents will only be granted upon verification that criteria dictated by Distribution D and export control restrictions are met by registered companies or organizations.

Foreign participation is excluded.

SECRET Clearance, at a minimum, is required.

Section III: Strategic Sourcing and Cost Reduction Approach (For Respondents B)

Acquisition Strategy Proposal: The Government's primary objective is to reduce unit cost and mitigate obsolescence. Describe a comprehensive business model or acquisition strategy your company could offer to achieve this.

  a.  If you are proposing a non-traditional model (e.g., third-party financing, bulk purchasing), describe the flow of funds, the flow of property, how inventory would be managed, and the risk allocation between your company and the Government (e.g., termination liability).

  b.  If you are a manufacturer, what alternative pricing or production strategies could you propose to lower the cost to the Government, aside from simply receiving larger orders?

Obsolescence Management: Describe your company’s approach to manage and mitigate obsolescence over a 5-10 year period under your proposed business model. Who bears the cost and responsibility for redesigns? How would you ensure long-term supply of critical components? (Modified version of original question 8)

Rough Order of Magnitude (ROM) Pricing: Provide ROM unit pricing for the B-Kit based on your proposed business model.
