[2] The coastal defence vessels are powered by four Jeumont ANR-53-50 alternators coupled to four Wärtsilä UD 23V12 diesel engines creating 7.2 megawatts (9,700 hp).

Two LIPS Z-drive azimuth thrusters are driven by two Jeumont CI 560L motors creating 3,000 horsepower (2,200 kW) and the Z drives can be rotated 360°.

[13] In February 2017, Summerside and Moncton deployed to the coast of West Africa in the Gulf of Guinea as part of the naval exercise Neptune Trident.

[19] In October 2018, Moncton was among the Canadian ships deployed to the North Atlantic and Baltic Sea as part of the large NATO exercise, Trident Juncture.
