Adaptable Strike Frigate

[Colin Parkinson]

My understanding was that we were going back to the 127mm (sometimes called the 5 inch gun ) gun as a surface warfare and land support weapon - not as an AAW weapon at all.

Apparently near the end of the war, the 5" was the predominate plane killer, radar and VT fuzes made the difference. I believe this is the gun we are getting This article goes deep into the Type 26 gun and it gives some good details on it.

In focus: the 127mm Mk 45 gun that will equip the Type 26 frigates - Navy Lookout

When the first Type 26 frigate becomes operational it will introduce another gun type to Royal Navy service. BAE Systems' renowned Mk 45 127mm (5-inch) gun is already proven with navies worldwide and will be a considerable upgrade on the existing medium calibre gun. Here we look at this weapon...

Canada Selects Leonardo Naval Gun Systems for the CSC Combat Ships - Naval News

Leonardo has been awarded a contract to supply four OTO 127/64 LW Vulcano naval guns for the Royal Canadian Navy’s new multi-role combat ships. The contract was further to a competitive international tender.

Going by Wiki there only about 19 mounts in service, so not as much user base as the BAE gun with some 250 mounts in service

Yah but the leonardo system is so much better, at least on paper. Faster rate of fire, higher calibre = higher muzzel velocity = longer ranges, better feed system from the magazine and a bunch of other stuff I can't be bothered to look up right now.

I do get the concern though. I think part of the selection was also because Leonardo submitted for the 30mm as well.
