Which NSN part numbers can you supply and how is a NSN number made?
The NSN part numbers that Anemo can supply are listed on following websites:

The 13-digit NATO Stock Number is comprised of three separate sections:
The first four digits of the code (FSCG) represent the Federal Supply Classification Group and were initially categorised according to classes of similar parts. Federal Supply Group 14, for example, is the class of guided missiles, with different categories within that class having 14 as the first two digits.
The second two digits -10, 20, 30, 40, etc. - represent the classification of a particular item within that class. Thus 1410 is the FSC for a guided missile, while 1430 is the missile's remote control system and 1440 the launcher.
The group of two digits following the first four shows which NCB assigned the NSN, with the USA being 00 and 01, and the UK 99. A guided missile launcher issued with an NSN by the UK, therefore, would be 1440-99.
The last seven digits of the NSN are each part's own identification number and are randomly allocated by a computer so that no significance should be given to any sequence or place in it. However, these last seven digits may be the same as the last seven digits assigned to a different item by a different NCB, but the preceding two digits will then be different.
Furthermore, it is possible that NATO may revise the first four digits of the supply classification so that the part numbers are regrouped, but the final nine digits (the NATO Item Identification Number, or NIIN) represent the fixed identity of the NSN, and will be unchanged throughout the item's lifecycle.
The NSN system works because it is uniform in its structure, composition and use, and can be applied to any supply item without modification. This unique numbering system is easy to assign, flexible and easily recognised by all its user nations, allowing the same equipment to be used everywhere. It also allows simple expansion, as each NCB code can support ten million different NSN parts.
The NSN is usually written for human users in this xxxx-yy-zzzzzzz fashion, but for automated readers, the dashes are omitted.
In the UK an additional alphanumeric code may be appended to the NSN for domestic management of military parts, which is known as the Domestic Management Code (DMC).
