The U.S. Air Force Symbol is a registered trademark. The Army Air Corps symbol (Hap Arnold Wings) and Air Force Emblem are two of many Air Force trademarks. Permission to use them for commercial use, in marketing materials, in advertising (free or paid), or by any non-federal organization/activity, including non-profit organizations, is required. The use of these trademarks for commercial purposes, including reproduction on merchandise, is expressly prohibited unless the producer completes a license agreement with the Air Force. Use is governed by the terms of the agreement.
Department of Defense and Air Force policy and regulations prohibit use of official Air Force markings, insignia and symbols in ways that imply endorsement of a commercial or non-federal entity or activity. (See CFR Part 2635.702 and the DoD Joint Ethics Regulation, DoD 5500.7-R.) This applies to all Air Force markings and symbols, including the Air Force Symbol.
The Air Force retains the right to withhold licensing of certain products, which includes, but is not limited to, alcohol, tobacco, drug or smoking paraphernalia, firearms, weapons of any type, undergarments, products sexual in nature, food or drink items (consumables), cosmetics (to include fragrances, soaps and hair products), medical devices or products contrary to the good order and discipline of the USAF.
Department of Defense employees, their families and veterans are required to get a license if they have a company, small business or hobby that intends to sell products bearing any Air Force trademark.
