This Air Force publication implements DoD Directive 4120.15E, Designating and Naming Military Aerospace Vehicles.  It provides guidance and procedures for designating and naming defense military aerospace vehicles across the DoD.  This AFI defines the roles and responsibilities of required organizations, the processes for requesting new or retiring old designators and popular names, and the relationship between and military aerospace vehicle designators and names.  Additionally, descriptions of standardized Mission Design Series (MDS) designation symbols, military department contacts, and sample MDS and Popular Name request letters are provided.  This instruction applies to all military services and departments, including Reserve and National Guard components, which require official designators or names for defense aerospace vehicles. Ensure that all records created as a result of processes prescribed in this publication are maintained in accordance with AFMAN 33-363, *Management of Records*, and disposed of in accordance with the Air Force Records Disposition Schedule (RDS) located at https://www.my.af.mil/afrims/afrims/afrims/rims.cfm.

Refer recommended changes and questions about this publication to the Office of Primary Responsibility (OPR) using the AF IMT 847, *Recommendation for Change of Publication*; route AF IMT 847s from the field through the appropriate functional's chain of command.

## Summary Of Changes

This document has been substantially revised and must be completely reviewed.  Major changes include MDS roles/responsibilities and request processing have been implemented in this Air Force Instruction revision.  These changes assign HAF/A8PE as the primary focal point for collecting, assigning, and processing both designator and popular name requests.  AFMC has been relieved as the MDS entry point DoD-wide.  Additionally, SAF/PA has been reassigned as coordinating POC only for popular names and SAF/GCQ has gained the responsibility of conducting trademark search from AFLOA/JAQ.  The request process has been redefined to reflect the realignment of responsibilities and detailed to provide clear MDS request criteria, request preparation, submission, and close-out.  All references to organizations and office have been updated as appropriate.  Acronyms and terminology have been updated as necessary; references to unmanned aerial vehicles (UAV) have been replaced with unmanned aircraft (UA).
Added request and processing time constraints, MDS designator position interpretation tables/examples, emphasis between standard and non-standard aircraft, and sample MDS designator and popular name packages.

## 1.  **Overview.**

1.1.  This Air Force instruction establishes guidance and procedures for requesting a Mission Design Series (MDS) designator and/or an MDS popular name for military aerospace vehicles.  All requested and approved MDS designators will adhere to the DoD designator reporting system established in 1961 to standardize identification of military aerospace vehicles.  This system uses letters and numbers to symbolize identifying characteristics of military aerospace vehicles of direct interest to the DoD (reference Attachments A3 and A4). All requested and approved MDS popular names will be suitable, in accordance with Air Force standards and values, for public release and not violate registered brand names, trademarks, or otherwise infringe upon copyright laws. 1.2.  The Secretary of the Air Force (SECAF) serves as the DoD Executive Agent (reference DoDD 5101.1, *DoD Executive Agent*) for the MDS program (reference DoDD 4120.15E). The SECAF delegated authority relating to standardizing references to military aerospace vehicles to HAF/A8PE (reference HAFMD 1-56, Deputy Chief of Staff Strategic Plans and Programs).  Acting on the behalf of the DoD Executive Agent, HAF/A8PE may not redelegate full authority of the MDS program, but does reserve the authority to arrange for and execute inter-Service support agreements, memoranda of understanding, and other necessary arrangements, as required, to fulfill assigned DoD Executive Agent responsibilities, functions, and authorities (reference DoDD 5101.1). 1.3.  This instruction provides DoD-wide guidance on the following: generating, collecting, evaluating, and processing MDS designator and popular name requests, specifying required and essential coordinating organizations, outlining MDS designator and popular name approval authorities, determining "next-in-series" MDS designators, and publishing updates to this instruction and a single DoD-wide list of approved MDS designators and popular names for aerospace vehicles.  Additionally, this instruction will provide the required evaluation criteria and MDS request package templates, standardized MDS designator symbols, and respective military department points of contacts. 1.4.  For the remainder length of this instruction, it will be understood that either "MDS
designator" or "MDS popular name" terms will relate to the designator or name for military defense aerospace vehicles and/or DoD aerospace vehicles only.  Furthermore, when references are made to the generic term "vehicle," it will be understood that it is in reference to military aerospace vehicle unless otherwise described.  This instruction does not apply to ground-based systems or vehicles (except for UAV control segments related to aerospace vehicles required to be controlled by rated pilots), any hybrid ground/aerospace vehicle in which its intended operational environment is ground-based, or any specific attachment or subsystem of a military defense aerospace vehicle.

## 3.  **Relationship Between Mds Designator And Popular Name.**

3.1.  The MDS designator is the official designation for military defense aerospace vehicles. The designator represents a specific category of vehicles for operations, support, and documentation purposes.  The MDS popular names characterize aerospace vehicle missions and aid communications and media references.  You may use either reference as a management tool; however, only refer to the MDS designator in official publications and technical manuals. 3.2.  The MDS designator and popular name for a military defense aerospace vehicle are requested in separate packages and processed and staffed separately.  An MDS designator for a new aerospace vehicle or a new configuration of an existing aerospace vehicle must be approved first before the popular name can be approved.  Requests for both an MDS designator and popular name relating to the same aerospace vehicle may be submitted simultaneously.  Stand-alone requests for an MDS popular name will automatically be rejected if it relates to the following: an unapproved MDS designator, an aerospace vehicle without an MDS designator, or any anticipated MDS designator request that has not yet been submitted and accepted for processing.

## 4.  **Mds Designator.** 4.1.  Designator Definition:

4.1.1.  The MDS designator is an official DoD recognized alpha-numeric symbol designation of a military defense aerospace vehicle.  A standardized set of symbols, established by the Secretary of Defense (SECDEF), are used for solely designating military defense aerospace vehicles categorized as: aircraft (standard or non-standard), guided missiles, rockets, probes, boosters, and satellites.  The designator describes the aerospace vehicle in two components where the components are separated by a dash. The first component, comprised only of alpha characters, describes the mission of the vehicle.  The second component, comprised of both alpha-numeric characters, describes the design number and design series of the vehicle. 4.1.2.  Standard aircraft MDS designators are comprised of the following: *status prefix* (optional), *modified mission* (optional), *basic mission* (required), design number
(required), design series (required).

4.1.3.  Non-standard aircraft MDS designators are comprised of the following: status prefix (optional), *modified mission* (optional), *basic mission* (required), *vehicle type* (required), design number (required), design series (required). 4.1.4.  Guided missiles, rockets, probes, boosters, and satellites MDS designators are comprised of the following: *status prefix* (optional), *launch environment* (required), basic mission (required), design number (required), design series (required). 4.1.5.  Only one designator symbol can be selected from each optional and required symbol categories.  For example, standard aircraft may only have one symbol selected (as applicable) as a status prefix, *modified mission*, and *basic mission*. 4.1.6.  For aircraft (standard and non-standard), *modified mission* symbols cannot be attached to similar *basic mission* symbols (e.g. "FF-16A") except for the modified and basic mission symbol "L". 4.1.7.  Designators not assigned and approved through the process outlined herein, but by the aerospace vehicle's manufacturer or another non-DoD agency or country is strictly prohibited and is not recognized as an official MDS designator.  Furthermore, the current format of the MDS designator was established by the US DoD on 18 Sep 1962 with the publishing of AFR 66-11, AR 700-26, and BUWEPS Instruction 13100.7 (a joint service instruction) and therefore the MDS designator format is owned by the DoD.

## 4.2.  Designator Request Eligibility:

4.2.1.  Prior to submitting any MDS designator request package, the following basic criteria must be met:
4.2.1.1.  The request pertains to an aerospace vehicle intended to become part of or already is part of the active DoD inventory. 4.2.1.2.  The designator is intended for a permanent aerospace vehicle acquisition.

4.2.1.2.1.  Requests are not accepted for military aerospace vehicles procured to meet Urgent Operational Needs (UON) or other temporary/non-permanent acquisition requirements including lease of the vehicle.

4.2.1.3.  The request pertains to a new designation or modification/revision to an existing designator.

4.2.1.3.1.  For military defense aerospace vehicles with an extensive history of MDS designations, requests are not accepted for designators in reverse or skipped sequences.

## 4.3.  Procedures For Requesting A Designator: 4.3.1.  Preparing The Request.

4.3.1.1.  Fully complete the MDS Designator Request Letter (reference Attachment A6)
4.3.1.1.1.  Request letter paragraph two and attachment one will remain blank or completed notionally until the Program Executive Officer (PEO) or Program Manager (PM) and/or Lead and Using Command/Service Department concurs with requested MDS designator 4.3.1.1.2.  Research and determine the "next-in-series" MDS designator to be requested (reference the MDS page on the DTIC DoDTechipedia website, see Attachment A1, or contact HAF/A8PE, see Attachment A5).  For standard aircraft, reference the *basic mission* designator and research the last approved design number and design series of that *basic mission* designator to determine the "next-in-series" MDS designator.  For non-standard aircraft, guided missiles, rockets, probes, boosters, and satellites, reference the *basic mission* and vehicle type designators and research the last approved design number and design series of that basic mission/*vehicle type* designator to determine the "next-in-series" MDS designator.

4.3.1.2.  Coordinate letter with requesting organization's respective Military Department point of contact (reference Attachment A5).

4.3.1.2.1.  **(For Air Force)**  Coordinate letter through requesting organization's applicable PEO or PM.

4.3.1.2.2.  **(For Air Force PEO/PM)**  Coordinate letter through the applicable lead command at the O-6 level.

4.3.1.3.  Update request letter paragraph two and attachment one to reflect PEO/PM and/or Lead and Using Command/Service Department concurrence with requested MDS designator.

## 4.3.2.  Submitting The Request.

4.3.2.1.4.  Ensure the name, office symbol, email address, and telephone number of the requesting official and agency is listed
4.3.2.2.  If designation request is classified, include declassification instructions.
Additionally, include an unclassified vehicle description for publication on the DTIC DoDTechipedia webpage.  Classified designation requests must adhere to the process outlined herein and routed to the appropriate organization and/or workflow account on a classified environment or communications system. 4.3.2.3.  Send completed, fully coordinated MDS designator request letter to the requesting organization's respective Military Department point of contact.

4.3.2.3.1.  **(Air Force, PEOs/PMs, and Lead/Using Commands)**  Send completed request letter package to HAF/A8PE.

4.3.2.3.2.  **(POCs for Military Departments)**  Send completed request letter package to HAF/A8PE after receipt, review, and approval from respective military department.

## 4.4.  Designator Request Letter Status And Closure:

4.4.1.  Upon receipt of a fully completed, coordinated MDS designator request letter package, HAF/A8PE will acknowledge the requesting department or agency normally within five working days as either "Accepted" or "Rejected."
4.4.1.1.  If the MDS designator request letter is accepted, the requested designator will be processed within 90 calendar days after acceptance.  Processing includes designator review and assignment,  staffing the designator through HAF and SAF at the four- (O-6), three- (O-7 or O-8), and two-letter levels (O-9), and final approval determination by HAF/A8.  The organization or agency requesting the designator will only be notified upon approval/disapproval of the designator or if processing exceeds 90 calendar days, whichever occurs first. 4.4.1.2.  If the MDS designator request letter is rejected, the requesting department or agency will be immediately notified with concise rationale for rejection.  Request letter packages requiring revision or modification in order to re-apply for requested designator must be fully re-submitted by the requesting department or agency. HAF/A8 or HAF/A8PE will not retain partial or rejected request packages.

4.4.2.  Request letter acceptance does not constitute approval of the MDS designator. Referencing an unapproved or pending MDS designator in regards to military defense aerospace vehicles in public announcements or other documentation is strictly prohibited. 4.4.3.  Upon approval of the MDS designator, HAF/A8PE will notify the Service POC, the SECAF, the CSAF, and other offices and agencies as appropriate, and provide a courtesy copy of the signed MDS designator approval letter (reference Attachment A12).

4.4.3.1.  HAF/A8PE will add/update the MDS designator on the DTIC DoDTechipedia webpage (monthy update, if changes occur) or other appropriate venue for public release.

## 5.  **Mds Popular Name.**

5.1.  Popular Name Definition:
5.1.1.  The MDS popular names characterize military aerospace vehicle missions and aid communications and media references.  Names should consist of no more than two distinct words.

5.1.2.  Names assigned or used by the aerospace vehicle's manufacturer are prohibited from use or reference as a DoD MDS popular name without the manurfacturer's permission and DoD approval.  Manufacturer assigned names may be requested after a trademark review and the manufacturer's permission is granted - all transactions must be routed through local PA offices and documented.

## 5.2.  Popular Name Guidelines:

5.2.1.  Names must be brief.  Use no more than two short words.  Choose a name that characterizes the mission and operational capabilities of the vehicle (see DTIC
DoDTechipedia for examples).

5.2.2.  Do not request a name that sounds phonetically the same as another (i.e. gryphon, griffin). 5.2.3.  Each MDS with the same *basic mission* and design number will normally keep the same popular name assigned to the original MDS, regardless of variations in manufacturer, operational use, or change in series.

## 5.3.  Popular Name Request Eligibility:

5.3.1.  Prior to submitting any MDS popular name request package, the following basic criteria must be met:
5.3.1.1.  The popular name to be requested is intended for a military aerospace vehicle that has been assigned an MDS designator or that has a designator request currently being processed.

5.3.1.1.1.  The aerospace vehicle has reached production or has immediate prospects of entering the DoD active inventory.

5.3.1.2.  The popular name does not violate any known brand names, trademarks, or otherwise infringe upon copyright laws. 5.3.1.3.  The popular name is within scope of DoD values and morals such that the name would not reflect negatively upon the DoD and is suitable for public release.

## 5.4.  Procedures For Requesting A Popular Name: 5.4.1.  Preparing The Request.

5.4.1.1.  Fully complete the MDS Popular Name Request Letter (reference Attachment A8)
5.4.1.1.1.

Design numbers run consecutively from "1" to "999" and will appear to the immediate right of the basic mission or vehicle type symbols, separated by a dash.

A2.1.6.1.1.  In the event that a *design number* of an aerospace vehicle reaches "999", the *design number* range will be expanded to "9999" and future *design numbers* will be assigned accordingly.  The designator character positions to the right of the dash separator will be expanded to accommodate the increased *design number* range. A2.1.6.1.2.  HAF/A8PE reserves the authority to skip *design number* at discretion. Skipped *design numbers* cannot be requested or used.

A2.1.6.2.  It will appear to the immediate right of the basic mission or *vehicle type* symbols, separated by a dash. A2.1.6.3.  For example, in the designator F-16A, the *design number* "16" represents the sixteenth approved MDS designator for an aircraft with a fighter mission under the current MDS reporting system.

## A2.1.7.  **Series**:

A2.1.7.1.  Is a required designator symbol for all standard and non-standard aircraft and all guided missiles, rockets, probes, boosters, and satellites.  It identifies the production model of a particular *design number* and later models representing major modifications that significantly alter the aerospace vehicle's systems, components, or change the logistics support of the vehicle. A2.1.7.2.  It will appear to the immediate right of the *design number* and follows a consecutive assignment starting with "A".  To avoid confusion with the *design number*, the use of letters "I" and "O" for this symbol are prohibited.

A2.1.7.2.1.  At the end of the *series* symbol "Z", the next sequence will be to advance the *design number* to the next consecutive unused number and begin with *series* symbol "A".

A2.1.7.3.  For example, in the designator F-16C, the *series* symbol "C" indicates the third production model of the F-16.

## A2.1.8.  **Aerospace Vehicle Configuration Or Specification**:

A2.1.8.1.  The following descriptions for configuration, block, and serial numbers further identify configuration or specific vehicles, but are not part of an MDS designator.
