Taking up Dave's comment..
The TROMP had a Full Load Displacement of 4,308 tons. (Frigate)
In comparison the UK Type 42 Destroyers like NEWCASTLE and GLASGOW were 4,250 fl after refits.
The Duke class frigates like NORTHUMBERLAND were 4,200 fl and the Type 22 frigates like BROADSWORD were 4,400 Full Load.
So our Type 22's, also classed as frigates had a higher Full Load displacement than TROMP.
The new TROMP, still classed as a Frigate is 6,145 tonnes Full Load Displacement.
And the Type 45 Destroyers like DARING are 7,570 tonnes Full Load Displacement.
Now should they have been classed as Cruisers????
