The VH-92 was selected to replace the VH-3 Sea King as the new Marine One. But this isn't the first time the Sea King has been supplanted by a variant of the S-92 — in fact, Canada already did the same thing with its fleet of 28 maritime combat helicopters.
Sikorsky S-92s in Canadian service that were modified for anti-submarine warfare are known as CH-148 Cyclones. These aircraft operate primarily from Canada's force of 12 Halifax-class frigates, which are equipped with RIM-7 Sea Sparrow missiles, RGM-84 Harpoon anti-ship missiles, a 57mm gun, and 324mm torpedo tubes.

These versatile helicopters are designed to hunt down submarines using the Mk 46 anti-submarine torpedo, but they also handle search and rescue, tactical transport, and surveillance missions.
The CH-148s are nearing the end of production. Canada has accepted 15 aircraft to date in an interim configuration, and begins accepting aircraft in a final production configuration in June 2018. Initial operational capability is slated to be achieved later in 2018. This much-anticipated helicopter is the result of an extremely long research and development program — the first helicopter that was delivered from the program was seven years behind schedule. To date, the program's total cost has ballooned to over twice its original size.
The CH-148 will also handle search-and-rescue missions, like this S-92 does for the Irish Coast Guard.

The CH-148 has a crew of four. In the anti-submarine warfare mode, it packs two Mk 46s. These torpedoes have a top speed of 45 knots and a maximum range of just under seven miles. As a tactical transport, it can haul 22 troops – roughly two squads of grunts. The helicopter has a top speed of 190 miles per hour and can go just under 280 miles without refueling.
