Below are the set of rules that are to be followed for the purpose of naming files posted for upload in the main archive.
Basic file name is to consist of up to three main elements (application of which will be further explained below) plus a filename extension:
1) hull classification symbol denoting the ship's purpose,
2) ship name, further subdivided into:
2.1) pennant number (if applicable),
2.2) name itself,
3) other information as needed,
and filename extension (preferably ".png")

It should be noted, that SB hull classification symbols are meant to serve as clear reference regarding the ship's purpose and to ease browsing the archive folders. Therefore these symbols, besides certain general simplifications, generally take precedence over classification peculiarities of particular operators. For example, we have accepted the convention that symbol MS (motor ship) denotes passenger(-capable) ships, while MV (motor vessel) denotes cargo/freight carrying ships (without significant passenger-carrying capabilities). Many operators, however, use either symbol for both these categories, therefore in the filename this distinction is to be observed, while the name of the ship given on the template is to be applied as in the real-life.
Vessels of the US uniformed services (US Navy, USCG, NOAA) using modern system of hull classification symbols (instituted on 1920 July 17), as well as ships of certain other navies that have adopted these rules (Republic of China Navy since 1950s, Republic of Korea Navy, Japanese Maritime Self-Defence force, Royal Canadian Navy since 1950s) use appropriate hull classification symbols in lieu of both point 1) and 2.1).
Files with all other vessels of these countries will be named according to basic rules.
Particular parts of the file name should be divided by space, but since many of the picture sharing services do not allow for spaces, the sign " _ " can be used instead.
Hull Classification Symbol (Hull Code)
For practical reasons three sets of hull classification symbols are to be in use.
- Generic set, largely derived from the US Navy set of symbols but for practical purposes not identical with it - in fact significantly diverging from it in some places. List of officially-approved symbols is posted below.
- Set of codes used by the US uniformed services and several other navies (as mentioned above) - these are to be followed literally along their real-life counterparts.
- Set of codes in the Russian language (but written in Latin alphabet) used by the Soviet/Russian Navy and navies created after the break-up of Soviet Union, with the exception of Lithuania, Latvia and Estonia. Symbols used by the Soviet Navy often did not correspond properly with the western warship classification, therefore a separate set is needed. Warships used by other countries (and posted to their respective folders) but built by Soviet Union will have generic set applied to them, though, NOT the Soviet one.
It has to be remembered, that sets 2) and 3) are to be used only for the appropriate navies and only in the valid timeframe. Civilian ships or military vessels that existed before the real-life implementation of these sets are to be named with "generic set".
If a drawing represents some very specialized ship, whose purpose can't be properly described by any of the mentioned symbols, Administrators may allow for additional symbol to be introduced. It would be suggested, however, to avoid creating new categories unless genuinely unavoidable.
This part consists of two elements: pennant number and name itself.
Pennant number is added whenever applicable, typically only on military vessels, in such form as in the real-life.
When a picture represents a whole class of ships, then the name and pennant number of the name ship of the class are used.
When a picture represents a particular ship from the class, then the name and pennant number of that particular ship are used.
In case of ships being obtained from outside sources, only the local name is used, with original (previous, in case of second-hand vessels) omitted, for example:
picture showing British frigate HMS Broadsword (pennant number F88) after it was sold to Brazil and named there Greenhalgh (pennant number F46) should not be named "FF Broadsword - Greenhalgh.png" or anything like that, but simply:
If a particular navy uses some country-specific class naming, like Soviet/Russian "project numbers" (Pr.205, Pr.956 etc.), German "type codes" (Kl.122, Kl.143 etc.) or Mainland Chinese "type numbers" (Type-053, Type-092 etc.), then a drawings representing whole classes may use such names instead, but only in their country of origin. Ships exported abroad will have only their local names given. Only partial exception to this are Soviet-bloc countries, where Soviet "project numbers" were/are functioning as de-facto local names, and also applied similarly to local designs (Poland, East Germany, Romania, Bulgaria, Cuba, Vietnam, North Korea, partially Mainland China).
In the case of Soviet/Russian and Mainland Chinese ships, the filename for is to contain the project/type number and NATO code, for example:
(hull code) Pr.956 Sovremenny.png
SSBN Type-092 Xia.png
When a ship class did not have NATO code (for the ships chronologically preceding creation of NATO) or has more well-known other name, the NATO code could be skipped or replaced with that name, for example:
(hull code) Pr.194 BMO.png
In case of Soviet/Russian ships transferred to Chinese Navy, pictures showing the whole class may be named with Soviet project number and Chinese type name instead of NATO code, for example:
The last rule is for ships with MARAD hull type codes - these are much more rare (and mostly US), but are rendered with the Hull code with spaces as the breaks followed by the ship's name:

We do not use prefixes like HMS, USS, SMS, ARA, ORP etc.
Other information as needed
Here additional information can be posted, like year, a digit extension (if there are more than one drawing of a ship at a particular year, or if there is a series of drawings representing several sub-variants of particular class etc.) or a brief bit of text.
