On the other hand, it's perhaps so modest that it does raise some sovereignty protection implications, which the committee might like to address. In terms of possible measures we could take, I'll run through these very fast: additional land, sea, and air deployments from southern Canada; improved multi-agency data sharing and analysis; the creation of a modest, and I stress modest, northern training centre; the retention and upgrading of the Arcturus, Arctic sovereignty aircraft, or what was nominally supposed to be an Arctic sovereignty aircraft but is now scheduled to be disposed of; acquire a supplement to the Twin Otter aircraft currently stationed in Yellowknife; acquire and we're looking at ...[+++]naval options an ice-capable seabed operations vessel; explore a full range of space-based sensors, unmanned aerial vehicles, and subsurface surveillance systems, northern terrain vehicles; explore the utility of high-frequency surface wave radar in the north I believe Dr. Leggatt spoke to you about that and acknowledged that it had some potential utility, but there were limitations; and, in the longer term, continue to explore the potential for installing air-independent propulsion power plants on the four recently acquired submarines.

Hon. Douglas Young (Minister of National Defence and Minister of Veterans Affairs, Lib.): Mr. Speaker, there are negotiations ongoing with the United States as a result of several installations, including the installations to the north for the radar warning systems that were there for many years, Argentia and other areas where American facilities were stationed for long periods of time.

In the 1960s, the naval radar station was expanded and a new high frequency direction finder centre was constructed and manned by almost 200 personnel.
