1. Responsibilities:
1.1. Department of the Air Force:

1.1.1. SAF/PA:

1.1.2. HQ USAF/PE:
1.1.3. HQ USAF/PED:
1.1.4. HQ USAF/JA. The Air Force Legal Services Agency (Judge Advocate General Patent Division) conducts a trademark search of proposed aerospace vehicle popular names.
1.1.5. HQ AFMC Aeronautical Systems Center (ASC):
1.1.6. HQ AFMC Public Affairs. Reviews requests for aerospace vehicle popular names from ASC.
1.2. Department of the Army--Office of the Assistant Secretary of the Army (Research, Development, and Acquisition [OASA [RDA]). The Deputy Assistant Secretary for Plans, Programs, and Policy is the Army single point of contact and is the official requesting agency for the Department of the Army.
1.3. Department of the Navy--Naval Air Warfare Center Aircraft Division Lakehurst/SRD Code SR32. The Systems Requirements Department is the Navy single point of contact and is the official requesting agency for the Department of the Navy.

2. Aerospace Vehicle Designation System. HQ ASC/ENOS assigns and HQ USAF/PE approves DoD aerospace vehicles according to their Mission Design Series (MDS). DoD established the current designator reporting system in 1961 to standardize identification of military aerospace vehicles. This system uses letters and numbers to symbolize identifying characteristics of aerospace vehicles of direct interest to DoD. This instruction specifically standardizes designation symbols according to AFI 33-105, C4 Systems Information Technology (formerly AFR 700-9, Volume 1) and DoD Manual 5000.12, DoD Manual for Standard Data Elements (Microfiche), July 1989.

3. Procedures for Requesting an MDS Designator:
3.1. The Military Departments must submit a written request for assignment of a distinctive MDS designator as early as possible in the development cycle. Coordinate requests with the Military Department point of contact and HQ ASC/ENOS as soon as possible to have an MDS designator assigned. HQ ASC/ENOS will assign the next available consecutive design number within each basic mission for new vehicles. Do not use MDS designators before approval. NOTE: Air Force agencies must coordinate MDS requests through the applicable system program office (SPO).
3.2. The Military Departments must request new designators, changes, or deletions through their single point of contact (see attachment 5). The department contact will send the request to HQ ASC/ENOS. NOTE: Air Force agencies send their requests to HQ ASC/ENOS.
3.2.1. HQ ASC/ENOS will assign the MDS designator and transmit the request to HQ USAF/PED, 1070 Air Force Pentagon, Washington DC 20330-1070, for processing and approval.
3.2.2. Use the reverse order to notify requesters of approval or disapproval.
3.3. Each request for new designations, changes, or deletions must include:

department.

3.4. Aerospace vehicles undergoing significant modification or design modernization need a new MDS designator to change the status prefix, modified mission, launch environment, or series symbols. Requests for these changes must comply with paragraph 3.3. To justify the new MDS designator, the request must include information on changes in operational capability, structure or system design, and logistics support requirements. The vehicle description should differentiate the new vehicle from other models with the same basic mission and design number.
3.5. The Military Department must include declassification instructions for classified designation requests. DoD Regulation 5200.1, Information Security Program Regulation, and departmental directives provide guidance. The vehicle description must be unclassified for publication in DoD 4120.15-L.
3.6. The Military Departments must coordinate with the Deputy Assistant Secretary of Defense (Production Resources) through the channels stated in paragraph 3.2. before:
3.6.1. Changing a basic mission or vehicle type symbol of an approved MDS designation (extraordinary circumstances must exist before taking this action).
3.6.2. Referencing aerospace vehicles in public announcements and other documentation.

4. Aerospace Vehicle Popular Name Guidelines. Military Departments will submit requests only for those aerospace vehicles that have reached production or have immediate prospects of entering the inventory.
4.1. Make names brief. Use no more than two short words. Choose a name which characterizes the mission and operational qualities of the vehicle (see DoD 4120.15-L for examples).
4.2. Submit at least three popular names in order of preference to ensure one will clear the review process.
4.3. Coordinate requests with the Military Department point of contact and HQ ASC/ENOS as soon as possible to get a popular name assigned. Do not use a popular name before approval. NOTE: Air Force agencies must coordinate popular name requests with the applicable SPO.
4.4. Note that each MDS with the same basic mission and design number will usually keep the name assigned to the original MDS, regardless of variations in manufacturer, operational use, or change in series. Use the procedures in paragraph 5 to request consideration of exceptions.
4.5. Note that the manufacturer or military services may reserve a set of names for future models for their exclusive use.

5. Procedures for Requesting a Popular Name:
5.1. The Military Departments must submit a written request for assignment of a popular name through the Military Department's single point of contact (see attachment 5). The department contact will send the request to HQ ASC/ENOS. NOTE: Air Force agencies send their requests to HQ ASC/ENOS.
5.1.1. HQ ASC/ENOS will check requested names for duplication against the master list of popular names and send the request to HQ AFMC/PA, 4375 Chidlaw Road, Suite 6, Wright-Patterson AFB OH 45433-5006.
5.1.2. HQ AFMC/PA will review the request and forward to SAF/PA, 1690 Air Force Pentagon, Washington DC 20330-1690, for processing and obtaining approval.
5.1.3. Processing must include a trademark search. Final coordination must come from the Assistant Secretary of Defense (Public Affairs) (ASD/PA) to ensure public suitability.
5.2. Use the reverse order to notify requesters of approval or disapproval. HQ USAF/PED will add the approved popular name to DoD 4120.15-L on notification from HQ ASC/ENOS.

6. Relationship of MDS Designator and Popular Name. MDS is the official designation for aerospace vehicles. The MDS represents a specific category of vehicles for operations, support, and documentation purposes. Popular names characterize aerospace vehicle missions and aid communications and media references. Use either reference as a management tool; however, refer to the MDS in official publications and technical manuals.

7. Retirement of Aerospace Vehicle Designator or Popular Name. When all aerospace vehicles with a specific MDS or popular name have retired from Service inventories, the Military Departments will notify the Service point of contact who will notify HQ ASC/ENOS. HQ ASC/ENOS will place these MDS designators and popular names on the retired list and will notify HQ USAF/PED in order to remove them from DoD 4120.15-L. NOTE: Air Force agencies will notify HQ ASC/ENOS through the applicable SPO.

8. Publication of Approved MDS Designators and Approved Popular Names. DoD 4120.15-L lists approved MDS designators for all military aerospace vehicles in the DoD inventory. The list displays MDS designator, manufacturer, approved popular name, engine data, using department, and a brief description.
8.1. All DoD Components must use DoD 4120.15-L. DoD Components can get copies through their own publication channels.
8.2. Other Federal Agencies and the public may get copies from the U.S. Department of Commerce, National Technical Information Service, 5285 Port Royal Road, Springfield, VA 22161.
