SBIRs, STTRs, DoD, and R&D. Vertx presents a Rosetta Stone for understanding the myriad of federal contracting acronyms businesses may encounter.

If you’re new to the world of federal contracting – particularly to contracting through the U.S. Air Force and/or Department of Defense – then this short guide can help you decipher several of the most commonplace acronyms/initialisms you’re likely to encounter. The distinction between an acronym and initialism, if you’re unfamiliar, is that an acronym takes the first letter of each word and arranges it into a new word to be pronounced, like NASA. Initialisms (sometimes called alphabetisms) see each letter pronounced separately, like the term CIA.
Let’s take a look at a few:
Governmental Entities
- USAF (initialism) – United States Air Force; the air service branch of the U.S. Armed Forces.
- DoD (initialism) – Department of Defense; an executive branch agency that is the largest in the nation. They are charged with managing all national security efforts in the United States. The USAF and all other service branches fall under their jurisdiction.
- USA (initialism) – United States Army; the operational military branch of the U.S. Armed forces.
- UMSC (initialism) – United States Marine Corps; the maritime land branch of the U.S. Armed Forces.
- USN (initialism) – United States Navy; the maritime service branch of the U.S. Armed Forces.
- USSF (initialism) – United States Space Force; the space service branch of the U.S. Armed Forces.

- ARNG (initialism) – Army Reserve/National Guard; the state-based reserve wing of the United States Army and United States Air Force.
