thanks for the information. I remember now that they want to build a military version of that chopper for the Canadian Air Force to replace the old sea Kings still flying. It is a long and stupid story which cost us billions. This one is probably an experimental craft.

It is actually an older Sea King type airframe--just tailored for civil use.

The military Sea King replacement in Canada is as baffling as the F-35 saga here. A lot of money and a lot of promises which turn into expensive empty promises.
