The Department of War’s Public Affairs office (Office of the Assistant to the Secretary of War for Public Affairs / Public Affairs) publishes the daily contract announcements; contracting activities submit award information to that office for public release.
The postings include large awards for goods, services, construction, and research & development when each award (or action) meets the $7.5 million reporting threshold; DoD-style daily contract lists generally cover multiple types of contract actions.
War.gov posts new contract announcements each business day (daily) at or about 5 p.m. Eastern/ Washington, D.C. time.
On the linked War.gov contract page, detailed award information (contractor name, award amount, contract scope, work locations, contracting activity) appears in the body text of each dated ‘Contracts for [date]’ entry—scroll to the entry’s full text or click the individual dated article link for the full award list.
Yes. War.gov offers RSS feeds of its news/contract pages (content feeds with headlines, summaries and links) that can be used to receive automated updates; agencies like DoD also publish contract announcements to machine-readable feeds or data endpoints.
The $7.5 million threshold refers to the face value of an award/action used for reporting/announcement purposes (i.e., awards or modifications with a face value of $7.5M or more); guidance treats the threshold as the reportable award amount, not an unrelated aggregate unless an agency rule specifies otherwise.
