**INTRODUCTION**

The Stand-in Attack Weapon (SiAW), Program Office (PO) is responsible for Air Force acquisition of next generation munitions built to rapidly strike mobile targets within an congested enemy environment.  The SiAW PO is currently executing a Middle Tier Acquisition (MTA) Rapid Prototyping phase. The purpose of this RFI is to conduct market research to identify potential sources capable of providing a SiAW equivalent missile system which consists of the All-Up-Round (AUR) missile to include hardware and software, as well as any unique logistics elements, trainers, SiAW flyout model, and all system verification elements. This AUR must be compatible with existing launch platforms and infrastructure currently supporting the SiAW.

THIS SOURCES SOUGHT IS NOT A REQUEST FOR PROPOSAL.  It is a market research tool being used to determine potential and eligible firms capable of providing the capability described herein prior to determining the method of acquisition and issuance of a Request for Proposal. The Government is not obligated to and will not pay for any information received from potential sources as a result of this sources sought.

**BACKGROUND/REQUIREMENT**

The USAF is seeking to enhance its capabilities to suppress and neutralize enemy air defenses in contested environments. This effort aims to identify and potentially acquire a weapon system that provides similar or improved capabilities compared to the SiAW, focusing on extended range, advanced targeting, counter-countermeasures, and integration with existing and future platforms.

**Required Capabilities**

Interested vendors are requested to provide information regarding their capabilities to provide a weapon system (or key subsystems) with the following characteristics (at a minimum):

* **Extended Range:** Weapon system capable of engaging targets at significant standoff distances.
* **Targeting:**
  + Advanced anti-radiation seeker with broad frequency coverage.
  + Ability to target modern and advanced radar systems, including frequency-agile and low-probability-of-intercept (LPI) emitters.
  + Ability to target modern ballistic threats, and other non-cooperative targets
  + Precision navigation and guidance system (e.g., GPS/INS with anti-jamming capabilities).
  + Potential for pre-emptive targeting capabilities.
  + Ability to re-attack.
* **Electronic Counter-Countermeasures (ECCM):** Robust ECCM capabilities to defeat enemy countermeasures, including chaff, flares, and jamming.
* **Lethality:** High probability of kill against a wide range of targets.

* **Logistics Support:** Comprehensive logistics support package, including training, maintenance manuals, spare parts, technical assistance, transportation and shipping at AUR and section level and missile compatibility with both CMBRE + and CE.
* **Cybersecurity:** Compliant with current cybersecurity standards for weapon systems IAW DoDI 8500.01, DoDI 5200.44, NIST SP 800-53, and CNSSI 1253 .
* **Exportability:** Expected to be open and modular such that future exportability and potential partner compatibility is not restricted.
* **Affordability & Producibility:** Capabilities should be affordable and producible in support of delivering quantities of up to 600 production AURs per year.
* **Security:** Expected to already have facilities and personnel to support classified requirements
  + Current access to CORE
  + Current ability to handle and process SECRET and TOP SECRET data and materials
