MILITARY IMO NUMBERS

[ALAN]

I understand that military ships are not issued with IMO numbers as merchant ships are but seem to have numbers beginning with 4******.  Where are these numbers obtained from and where can they be found and listed?

I know merchant ships are issued with an IMO registration which is kept for the life of the ship even when it changes name.

I hope someone can direct me to where I can find the registration numbers that are given to warships.

Many thanks

Hi Alan,

you can find numbers for active vessels here:
https://webaccounts.imo.org/Common/weblogin.aspx?ReturnUrl=%2f&error_message=interaction_required

You can register as a "Public User", it's a free account.

However, not all military vessels seem to have an IMO number (e.g. only few Turkish vessels have one) and the IMO database does not list vessels that have already been broken up or are out of service for other reasons.

Hope this helps.

Cheers,

Jens

PS:

Sometimes if you're lucky you can also find numbers for ships that have already been scrapped on Wikipedia, like in the English articles for the British type 42 destroyers...

at least some military/navy vessels do have IMO numbers:

here is one example:
