Some common abbreviations are:

Dam - damaged

Sdam - seriously damaged

O/O - on order

Std - stored

Wfs - withdrawn from service

Wfu - withdrawn from use

Scr - scrapped

Ukn - whereabouts unknown

Hope this helps.

Very helpful thanks.

One question - what is the difference between WFS and WFU?

Not quite sure of the official meaning. To me they mean:

WFS means it has been taken out of service and are often stored, sometimes they come out of storage and are re added to the fleet. WFS is sometimes temporary whilst its fate is decided.

WFU means they have been withdrawn from use, often stored and often they are stripped for parts or fittings before scrapping. WFU tends to be permanent leading to being scrapped.

Hi Mark,

In what context is sis used?

Not sure how it was used on the occasion your referring but have seen 'sis' used for 'seen in service'

Not sure if that helps or fits with the one you saw.
