United States Mythic Materiel Nomenclature — Prefix System

Design principle

The creature name is the primary and unmodified name. The designation is only a compact prefix that tells you what the equipment is, its role, and its generation.

<service>.<class>.<tier> <Creature Name>

Optional role suffixes may be inserted only when two live designs of the same class and tier must be distinguished:

<service>.<class>.<tier>.<role> <Creature Name>

The system therefore favors names exactly as written in HOI4-mythic-nomenclature.md—including spaces, hyphens, and established wording. Do not alter a creature name into a compound or append a descriptor merely to make it unique. The prefix already provides the practical identification.

Examples:

Ar.MT.I Lion
Ar.MT.II Tiger
Ar.MTD.III Peryton
AAF.FTR.III Giant Eagle
N.DD.II Barracuda
N.CF.III Gargoyle
J.SP.IV Iron Golem

Prefix key

Service codes

Class codes

Tier codes

A Roman numeral is intentionally preferable to a presumed calendar year. It keeps the designation valid whether you use historical research timing, rush technology, design a variant, or play with a technology-altering mod.

Optional role codes

Complete primary-name roster

Use every mythic name below unchanged. The prefix is the only systematic identifier normally needed.

Armored vehicles

Land-based aircraft

Carrier aviation

Naval vessels

For ships, assign the first four names to standard hull generations. Preserve the fifth as a reserved designation for an extraordinary refit, special-project hull, post-war continuation, or a mod-added fifth hull.

Special project reserve

Applying the system in-game

• Enter the displayed string directly as the design name whenever the equipment designer allows it.
• Use the class prefix to identify the item instantly in production, logistics, stockpile, and division-equipment lists; the mythic name remains visually dominant and flavorful.
• For an alternate design using the same role and tier, add a short, technical role code without changing the creature name. For example: Ar.MT.III.Gun Saber-Toothed Tiger and Ar.MT.III.Atk Saber-Toothed Tiger.
• If two otherwise identical production variants must coexist, use a final letter only: Ar.MT.III.A Tiger-A and Ar.MT.III.B Tiger-B. This is preferable to altering the source creature name.
• Where the same raw creature occurs in two source rows, keep it unchanged. Context is supplied by the systematic prefix: AAF.FTR.IV Wyvern and AAF.CAS.III Wyvern are immediately distinguishable.

Scope boundary

This is intentionally a naming standard rather than a claim that every listed role has a separate, five-generation vanilla HOI4 technology line. The source framework itself defines its five tiers as a sequence of names rather than a literal historical generation or a creature combat-rating scale. The prefix system preserves that approach while making each name legible at a glance in a full-DLC campaign.
