This SOW specifically applies to Delivery Order (DO) 1 for the APAC IDIQ contract. The contractor will ensure understanding of the overall intent and mechanics for issuing Fair Opportunity Proposal Requests (FOPRs) for the APAC MAC IDIQ. The contractor will have the opportunity to present additional propulsion capabilities.

Not explicitly detailed in this section of the SOW.

Not explicitly detailed in this section of the SOW.

• The contractor shall provide a presentation to complete the following tasks:
  • Attend a one-hour virtual post award orientation conference (PAOC).
  • Provide a 30-minute briefing to the Government to discuss future areas of capability relevant to propulsion technology, identify benefits of current and future capabilities, and highlight company strengths.
  • Presentation materials must be provided no later than five business days prior to the PAOC to the PCO via email or DOD SAFE.

Other / Unclassified

This document contains two clauses related to the Advanced Propulsion Acquisition Contract (APAC) IDIQ:

• FA8626.52.219-9ZH1 ON-RAMPING (JULY 2025): This clause outlines the Government's right to reopen competition or "on-ramp" additional contractors to the APAC contract. This can occur at any time during the contract term to enhance competition, particularly if there's a lack of robust competition for Fair Opportunity Proposal Requests (FOPRs) or a shrinking of original awardees. The on-ramp process will involve a reopening announcement on SAM.gov, and new awardees will be evaluated using the same criteria as the initial solicitation. Any new clauses or updates incorporated during an on-ramp will be applied via bilateral modification. Additions will not impact the contract ceiling or extend the ordering period beyond the original IDIQ contract term. Unsolicited requests for addition will not be considered.
• FA8626.52.219-9ZH2 OFF-RAMPING (JULY 2025): This clause details the Government's unilateral right to "off-ramp" non-performing Contractors from the APAC IDIQ. Contractors must have no active task orders to be eligible for off-ramping. Methods for off-ramping include the PCO determining it's not in the Government's best interest, debarment, suspension, ineligibility (per FAR Subpart 9.4), or termination (per FAR Part 49.4).

These clauses are critical for potential bidders as they define the conditions and processes for both adding new contractors (on-ramping) and removing underperforming contractors (off-ramping) from the APAC IDIQ contract. Understanding these mechanisms is essential for assessing the long-term competitive landscape and the stability of the contract awardees.

Amendment / Modification

This document outlines provisions for "On-Ramping" and "Off-Ramping" under an existing contract, likely an Indefinite Delivery Indefinite Quantity (IDIQ) contract.

On-Ramping (FA8626.52.219-9ZH1):

• The Government reserves the right to reopen competition or "on-ramp" additional contractors during the contract term.
• This may occur if the Government determines it is in their best interest to enhance competition, especially if there's a lack of robust competition for Fair Opportunity Proposal Requests (FOPRs) or a shrinking of original awardees.
• On-ramped awardees will be selected based on the same criteria as the initial solicitation.
• The reopening will be advertised on SAM.gov.
• New awardees will compete with existing contractors for task orders.
• The reopened solicitation may include updated clauses, which will be incorporated via bilateral modification for existing contractors.
• On-ramps will not impact the contract ceiling or extend the ordering period beyond the original IDIQ contract's maximum term.
• Unsolicited requests for addition to the contract will not be considered.

Off-Ramping (FA8626.52.219-9ZH2):

• The Government reserves the unilateral right to off-ramp non-performing contractors.
• Off-ramped contractors will have no active task orders at the time of removal.
• Off-ramping methods include:
  • PCO determination that exercising an option is not in the Government's best interest.
  • Debarment, suspension, or ineligibility as defined in FAR.
  • Termination as defined in FAR.
• Contractor's sole remedy for breach by the Government is limited to termination for convenience damages, task order proposal preparation costs, task order award, and/or reinstatement at the Government's discretion. The Government is not liable for expectancy or consequential damages, including lost profits.

Statement of Work (SOW) / Performance Work Statement (PWS)

This Statement of Work (SOW) outlines the requirements for the Advanced Propulsion Acquisition Contract (APAC) Multiple Award Contract (MAC) Indefinite Delivery Indefinite Quantity (IDIQ). The contract aims to provide the Air Force Life Cycle Management Center Propulsion Directorate (AFLCMC/LP) with the capacity to rapidly develop technologies for novel propulsion capabilities, implement unique solutions, advance new technologies, and provide evolutionary, revolutionary, and disruptive capabilities for the U.S. Air Force and strategic partners. It supports all lifecycle phases of propulsion development, from technology maturation to sustainment, while maximizing the use of the digital environment.

The contract focuses on the enhancement of propulsion technology across its lifecycle, including but not limited to:

• Science and Technology (S&T)
• Research and Development (R&D)
• Test and Evaluation (T&E)
• Integration and Assembly
• Production and Fielding
• Operations and Sustainment (O&S)

The evaluation will be based on Factor 1: Technical Proficiency, which includes three subfactors:

• Subfactor 1: Technical Capability: Offerors must submit two detailed efforts demonstrating capability in areas such as Science & Technology, Research and Development, Test and Evaluation, Integration and Assembly, Production and Fielding, Operations and Sustainment, Modernization, Prototyping, Experimentation, Hardware and Software Modification, Propulsion Design, and Data Mining, Collection, and Analysis.
• Subfactor 2: Propulsion Industry Relevance (PIR): Offerors must describe prior experience in performing work related to propulsion-relevant technologies.
• Subfactor 3: Small Business Participation Commitment Document (SBPCD): Offerors must demonstrate a realistic and credible approach to small business utilization.

Subfactors 1 and 2 are of equal importance and are significantly more important than Subfactor 3.

• This is a Multiple Award Contract (MAC) IDIQ.

• The government intends to award to all qualifying offerors.

• Initial Delivery Orders (DOs) will be for $1,000.00 to participate in a post-award orientation conference (PAOC).

• Potential future on-ramp opportunities are planned.

• Proposals will be evaluated on an acceptable or unacceptable basis for Factor 1, Technical Proficiency.

• Offerors must achieve an acceptable rating for all three subfactors to be eligible for award.

• The government reserves the right to award based on the initial proposal without discussions.

• Proposals must comply with all solicitation requirements, including Section L (Proposal Preparation).

• Page limitations will be enforced.

• No specific small business minimum quantitative requirement is specified for the contract, but SB utilization will be considered for all DO/TOs.

• Offerors must identify any exceptions to solicitation terms and conditions with rationale.

• Organizational Conflict of Interest (OCI) plans will be evaluated.

• A compliance statement demonstrating adherence to requirements is necessary.

• Small Business Subcontracting Plans are required for contracts exceeding $950K.

• The Delivery Order 01 (DO1) Statement of Work requires a proposed price of exactly $1,000 for the PAOC, which will be evaluated for reasonableness and balanced pricing.
