Table 4.7 Militarily useful British-registered merchant specialist and fishing vessels by principal categories and sizes at 31 December each year
Militarily useful British-registered merchant vessels are vessels that could be requisitioned in the appropriate circumstances in support of the Armed Forces. Other types of ship might also be used in certain cases. Foreign-flagged but British-owned ships could also be requisitioned in certain circumstances.

The information in this table is for UK Overseas Territories: Anguilla, British Antarctic Territory, Bermuda, British Indian Ocean Territory, Belize [British], British Virgin Islands, Cayman Islands, Falkland Islands (and Dependencies), Gibraltar, Montserrat, St Helena, Turks and Caicos Islands.
This list of countries differs slightly from the list used by the FCO.

1. The content of the Department for Transport's world fleet database was revised in 2009 to reflect changes in the classification of ships in the underlying data provided by HIS Fairplay. As far as possible 2008 figures have been provided on the same basis. Statistics prior to 2008 were based on DfT information from a range of sources, some of which are no longer available - therefore there are larger discontinuities before 2008.
