Halifax 57 Art
Below we see the Royal Canadian Navy Halifax-class frigate HMCS Vancouver (FFH 331) arriving at Busan, South Korea last week as part of the RCN’s continuing Operation Neon— Canada’s contribution to the monitoring of United Nations Security Council sanctions designed to pressure North Korea to abandon its weapons of mass destruction programs. Note the art on the rear of Vandy’s Bofors 57mm L/70 Mk3 naval gun.
The dozen Halifaxes all have similar gun shield art as a matter of pride.
