A generation ago, the distinction in size and firepower between a frigate and a destroyer would have been quite different. Nowadays, they've probably morphed in size of ship.
I think what has happened is, as we've retired our Tribal-class destroyers, the two capabilities that were unique to them in the navy were command and control of a task group and what we would call area air defence, which is an umbrella of missile capability that could protect all of the ships.
We have had evolution in both areas that has enabled us to do some work with our Halifax-class frigates and we've fitted the first four ships, which is the part that you're talking about. We literally moved bulkheads. We moved walls and did everything and actually designed, quite frankly, a better command and control capability than the destroyers had. We've completely modernized all the command and control, so there's the ship command and control, but there's also the task group commander's command and control that we've fitted in the ship.
We have retained the ability to command a Canadian task group, but we can also command an international task group by retrofitting and also deploying those ships. Interestingly, there was a bigger challenge. You have to embark a lot more people, because the commodore comes with a lot of staff, and we had to do a lot of work around habitability or what we would call heads and wash places, and bunks. That was an interesting challenge. The navy has basically maintained, and in fact from the early feedback we're getting from ships in the Black Sea or otherwise, improved, and not so much made it a destroyer, but provided it with the task group command and control capability that was otherwise being retired with the destroyers.
