Nothing wrong with any of the Cormorant, Cyclone or Chinook for moving light vehicles from ship to shore. Especially when they don't actually have to be based on the ship. They can lift off from Resolute, Iqaluit, Rankin or Inuvik, fly out to the ship, refuel, pickup cargo and deposit it on some other island, another ship or on the ice, then return to primary with a refuelling stop on the AOPS along the way.
We have the kit. We even have the bodies. We don't seem to have a plan or the inclination.
