USCGC Alexander Hamilton

USCGC "Alexander Hamilton" (WPG-34) was a . She was named after the first U.S. Secretary of the Treasury, Alexander Hamilton. Sunk after an attack by a German U-boat in January 1942, the "Hamilton" was the U.S. Coast Guard's first loss of World War II.
Design.
The design of the "Alexander Hamilton" was based on the U.S. Navy's Erie-class of gunboats. This "Treasury"-class of U.S. Coast Guard cutters was sometimes referred to as the "Secretary"-class.
History.
The "Hamilton" was built at the New York Navy Yard for the U.S. Coast Guard. Her keel was laid on September 11, 1935 and she was launched on January 6, 1937. The U.S. Coast Guard had truncated her name to "Hamilton" that year, but resumed using the full name in January 1942 after a request by the U.S. Navy to avoid confusion with the destroyer USS "Hamilton".
Sinking.
On January 29, 1942, the "Hamilton" was torpedoed on the starboard side by the , which had been patrolling the Icelandic coast near Reykjavík. The explosion killed twenty men instantly and the total death toll was 26. After she capsized on January 30, salvage attempts were abandoned and the American destroyer USS "Ericsson" fired upon the wreck three times to send her to the bottom of the sea, from the coast.
Discovery of shipwreck.
On August 19, 2009, the Icelandic Coast Guard discovered a shipwreck believed to be the "Hamilton" in Faxaflói. After she was positively identified using the technology of a Gavia AUV (Autonomous Underwater Vehicle), Microsoft co-founder Paul Allen flew to Iceland in August 2010 with an entourage to visit the wreck in a mini-submarine. His luxury yacht, the "Octopus", arrived separately at Reykjavík Harbor for the trip.
On June 26, 2011, a team of divers including Team Blue Immersions Jonas Samuelsson, Aron Arngrimsson and Valgeir Petursson left Reykjavik at 5am departing for "Alexander Hamilton" wreck. At 30 miles out and 95 meters down, the wreck lies upside down. This is the first dive team that ever dived this wreck.
The dive went without any problems and the conditions were better than expected. The sea at the surface was pretty rough and most (including Icelandic Coast Guard) warned not to take the boat out, saying the dive was impossible to conduct under current conditions . Visibility at the wreck was around 4 meters. Temperature was 7° C (44.6° F) at 90 meters, which was warmer than divers prepared for.
During the deep dive the divers set three Icelandic diving records: Deepest wreck dive in Iceland, deepest sea dive in Iceland, and deepest dive ever made in Iceland.
Attaching memorial plaque on Alexander Hamilton.
Team Blue Immersion, including divers Jonas Samuelsson, Aron Arngrimsson, Erik Brown, Chris Haslam in partnership with the diving company OceanReef returned to "Alexander Hamilton" in August 2013. On the assignment from the families related to the men that served on the cutter during World War II the Team dived down and attached a memorial plaque on the ship. The plaque listed all men that served and died during the attack by the German VII Submarine on the 29th of January 1942, just seven and a half weeks after the attack on Pearl Harbor.
On August 10, just two days before the Team Blue Immersions reached the 1937 Cutter "Alexander Hamilton", a new US Coast Guard Cutter Hamilton was launched in the water for the first time. This ship is the sixth cutter named after "Alexander Hamilton".
