The US Coast Guard Cutter James arrived around 2pm today. She is brand new, having just been commissioned on August 8 in Boston.
The 5th National Security Cutter, at 418′ in length they are similar in size to a Canadian Patrol Frigate. They also Use the same 57mm gun. The builder has proposed 2 frigate variants, so this may be a technology show for the Single Surface Combatant to be built under NSPS.
I believe she is the First National Security Cutter to Visit Halifax.
