- The U.S. Army extended the deadline for proposals under RFP W519TC-25-R-0034 and issued updated requirements for 5.56mm, 7.62mm, and .50 caliber ammunition production.
- The Army adjusted sourcing, quantity limits, and nitrocellulose pricing rules as part of new guidance to bidders preparing offers for the second-source ammunition contract.
The United States Army has issued updated solicitation materials for a new second-source supplier to manufacture 5.56mm, 7.62mm, and .50 caliber ammunition, releasing revised documentation.
The updated announcement was published on January 6, 2026, extending the proposal deadline and issuing new guidance on production requirements.
According to the notice, Amendment 0001 moves the proposal submission deadline to February 17, 2026, and updates several clauses and provisions. The Army said the change was made following industry requests for additional time to review the technical data packages and submit detailed questions to the contracting office. The service stated that the full solicitation and attachments are available through the Procurement Integrated Enterprise Environment (PIEE), which remains the primary submission portal.
The Army released an extensive Questions and Answers document to address industry concerns, including production thresholds, sourcing rules, scheduling, technical data controls, and pricing structures. The document clarifies that the service will not provide minimum guaranteed quantities for any caliber but has adjusted its procurement ceiling for .50 caliber ammunition. The Army said it will reduce the maximum quantity from 20 million to 15 million rounds per Ordering Period and will allow deliveries over 10 million rounds to be completed within two years of award.
In the Q&A, the Army confirmed it will not authorize foreign sourcing of finished components outside the U.S. and Canada. The service stated that any item called out in a controlled or advisory drawing—such as case cups, projectiles, cores, and penetrators—must be sourced domestically or from Canada, and importing partially finished components for domestic completion does not meet the requirement.
The Army also announced structural changes to the contract’s ordering periods. The government agreed to expand the structure from five to six Ordering Periods, with Ordering Period 5 running from October 1, 2029, to September 30, 2030, and Ordering Period 6 extending from October 1, 2030, to five years from the date of award. The service said this revision is intended to balance performance timelines and avoid extended single-period durations.
In response to industry questions on cost adjustments, the Army said it will maintain baseline pricing rules for Economic Price Adjustment materials, with the exception of nitrocellulose. The service agreed to include Ordering Period 1 in the nitrocellulose re-opener language and will add a reconciliation process to match actual pricing delivered by Radford Army Ammunition Plant. Other categories—including overhead and general administrative adjustments—will not be included in price revisions.
The Q&A also clarifies restrictions surrounding Controlled Unclassified Information (CUI). All Distribution D Technical Data Packages will be treated as CUI, and the Army confirmed that contractor-generated outputs such as ballistic testing, quality reports, and consistency data must also be handled under CUI protocols.
The Army said it will furnish required test equipment after contract award and will add the M4A1 carbine to the list of government-provided items. The service plans to coordinate quantities directly with the selected contractor to ensure required testing can be completed.
The solicitation—classified under NAICS 332992 (Small Arms Ammunition Manufacturing)—is intended to expand U.S. production capacity across three core calibers following sustained demand for training and operational stocks. The Army contracting office reiterated that Ordering Period 1 will not be skipped and that the minimum guaranteed quantity will be awarded in the first period.
The Army’s updated solicitation signals a clear intent to expand domestic ammunition manufacturing capacity and secure a stable second source for key calibers used across U.S. forces.
