The company announced Monday that it has a shovel-ready site in Meridian for the plant, which spokesman B.J. Boling says would create hundreds of jobs.
Three other international partnerships are competing: One includes Northrop Grumman Corp. and BAE Systems of London; another incluses Boeing and Saab AB of Stockholm; the third is Lockheed Martin and Korean Aerospace Industries.
Raytheon's principal partners are Leonardo-Finmeccanica of Rome, CAE USA and Honeywell Aerospace.
Boling says in an email that the Air Force is expected to formally ask for proposals in December.
