1 A National Stock Number, or NATO Stock Number (NSN), is a 13-digit numeric code, identifying all standardized material items of supplies as they have been recognized by all NATO countries.

2 Alternate source includes parts from a different manufacturer (not already in the applicable technical data package) that meet the part specifications.

4 Design refresh refers to changes that “have to be done” in order for the system functionality to remain useable. Redesign means “want to be done” system changes, which include new technologies to accommodate system functional growth and new technologies to replace and improve the existing functionality of the system (Herald, 2000).
