STATEMENT OF REQUIREMENTS

For

Hillstone 270 VDC Load Bank

1 MXS/MXMG

6 December 2024

Purpose: This Statement of Requirements outlines the need for the Hillstone 270 VDC Load Bank to support the Aerospace Ground Equipment Flight of the 1st Maintenance Squadron. Theis new load bank is critical for testing our current fleet of power carts. The load bank is also compact and portable, making it easy to transport and use at various Temporary Duty (TDY) and Deployment locations to support three separate Fighter Generation Squadrons (FGS) simultaneously, often operating in different locations across the globe. Additionally, the Hillstone 270 VDC load bank has been specifically designed to meet the unique requirements of our power carts, which are used to support critical mission operations.

Our existing load bank is not portable and does NOT meet mission requirements if needed in another location, as our current one is not portable. It is made for home station and not for use at TDY and deployment locations.

Internal Configuration: The ISUs must be designed to support two separate work centers, allowing efficient storage and organization of deployment assets for UTC HFBE1 missions and TDY certification events for Fighter Generation Squadron and training exercises.

Quick Access to Tools & Equipment: The layout must ensure rapid access to tools and equipment without needing to unpack or reconfigure to get any one tool/item. Reducing response times and allowing seamless integration into Agile Combat Employment configurations.

Airworthiness Compliance: Each ISU-90 must meet all airworthiness standards to support worldwide deployment to any location including bare base environments.

Hazardous Materials Storage: The ISU-90s must be able to safely store and transport hazardous materials, including flammable liquids and corrosives.

Efficient Layout for Tools & Parts: The internal layout must organize all tools and supporting equipment efficiently, with room to store unserviceable parts for return transport.

Split Serviceability: The ISU-90 must be designed with a split configuration, where one side supports the Egress section and the other supports Fuel Systems.

Note: Attached are photos showcasing the storage requirements (and lack thereof) and the current unserviceable condition of the existing units for your reference. We need to fabricate and deliver ISU-90 containers to the Accessories Flight, 1st Maintenance Squadron, ZIP code 23665 prior to April 1, 2025.
