Southbound off Quadra Island, BC; December 11, 2012;
RCN Iroquois-Class (Tribal-Class or 280-Class) air defence destroyer;
gloomy weather and navy grey colours of the vessel make the photograph look like a Black and white one.

note: add the last part(DDG_283) that is not highlighted in blue, as shipspotting fails to highlight this part
