HMS Trusty
Five ships of the Royal Navy have borne the name HMS Trusty:

Because Trusty served in the navy's Egyptian campaign (8 March to 2 September 1801), her officers and crew qualified for the clasp "Egypt" to the Naval General Service Medal, which the Admiralty issued in 1847 to all surviving claimants.
