Colin (and Jack), I think you are treading the same path as the critics of the Yankee LCS programme - in days gone by guns were the only means of reaching out and touching somebody. Missiles changed that game and perhaps more thought should go into leaving deck space for bolt on systems like the Harpoon and SeaRAM. But most folks don't seem to see the role of the armed helo, and more to the point the armed UAV (like the Firescout), in extending the surveillance envelope as well as the range at which targets can be engaged while the launching platform is mast-down over the horizon.
If any CF vessel on patrol is actively engaged by a near-peer vessel in a one-on-one engagement I am guessing that that is not a preferred scenario for any skipper. Ideally I would think the preferred plan would be to detect before being detected and then vector HE to the target. That HE can be delivered by Patrol Aircraft, Fighter, Armed Helo, Predator, Firescout or those traditional, disposable UAVs -guided missiles.
But the AOPS, I don't believe, is expected to be operating in those types of situations. Most of its time is going to be spent in boring show-the-flag sovereignty patrols in a very quiet arctic while standing as gate guard on the Northwest Passage and as SAR guard for civil air traffic.
The rest of the time will be spent with the following comms "Radio Check" and "Nothing to Report".
But....
Having said that, it is important that those negative reports be filed as they verify our claim to the territory by right of regular usage.
