The U.S. Army seeks continued secure storage and support for 155mm artillery ammunition at Camp Navajo, Arizona, primarily to support Modular Artillery Charge System testing at Yuma Proving Ground.
- **Requirement and purpose**
  - Services include secure storage, material handling, maintenance, periodic inventory and inspection, and ground transport of ammunition to and from Yuma Proving Ground.
  - Ammunition must be kept in explosive-rated magazines or igloos and handled by trained, certified personnel following applicable DoD and Army hazardous-material requirements.
  - The work supports scheduled testing and PM CAS program requirements.
- **Source and procurement approach**
  - The Army identifies the Arizona Department of Emergency and Military Affairs (DEMA), Ordnance Operations Department at Camp Navajo, as the sole-source provider.
  - The justification states that Camp Navajo is the only capable nearby explosive-storage facility and that using another source could cause schedule delays or duplicated costs.
  - The initial release describes a one-year extension under contract W15QKN-21-C-0002. The attached procurement summary describes a base year, four option years, and a priced six-month extension under FAR 52.217-8; these are distinct performance-period descriptions in the provided materials.
- **Timing and quantities**
  - The attachment projects award in March 2026. Specific start and end dates are not provided.
  - No ammunition quantities, product part numbers, or contract value are stated.

### Description

<p>In accordance with Federal Acquisition Regulation (FAR) 6.305, the U.S. Army Contracting Command &ndash; Rock Island at Picatinny (ACC-RI-PICA), on behalf of the Project Manager for Combat Ammunition Systems (PM CAS), is hereby posting the Justification and Approval (J&amp;A) for a sole-source action to the Arizona Department of Emergency and Military Affairs (DEMA).</p>

<p>This justification, Control Number CAO-26-0032, provides the authority for a one-year extension of services under contract W15QKN-21-C-0002 for the continued storage, material handling, maintenance, and inspection of 155mm artillery ammunition at Camp Navajo, AZ.</p>

<p>This action is necessary to ensure continuity of these critical services and prevent a gap in mission support while a long-term follow-on contract is finalized. The action was justified in accordance with FAR 13.501(a)(1)(ii), as DEMA is the only responsible source capable of meeting the Government&#39;s requirements without unacceptable schedule delays and duplication of cost.</p>

<p>The redacted Justification and Approval document is attached.</p>
