MACKINAW USCGC icebreaker-buoy-tender

Built as a icebreaker-buoy-tender under yard no 601 by Marinette Marine Corporation (MMC), Marinette, USA for the USA Coastguard.

Laid down: February 09, 2004.
Launched: April 2, 2005 under the name USCGC MACKINAW (WLBB-30), the name Mackinaw has its roots in the ancient Native American language of the Great Lakes. Specifically, it is derived from the word Michilimackinac in the Ojibwa language, meaning "Island of the Great Turtle." Both Mackinaw (the English derivation) and Mackinac (the French derivation where "ac" is pronounced "aw") are derived from this word and pronounced Mak'ino.
Displacement 3,500 ton, dim. 73 x 17.8 x 4.9m. (draught), length bpp. 69.9m.
The ship is powered by 3 Caterpillar Turbocharged V-12 engines that drive 2 ABB electric propulsion drives that deliver a combined 9,200 horsepower. They are Caterpillar 3612 engines, turning Kato Generators. Mackinaw has 3 MDG’s. Each producing about 3.5 Megawatts of electric power. Mackinaw has an integrated electric plant. This means that the main generators provide electric power for both propulsion (ABB Azipods) and ship’s electric services (everything else). Speed 16 knots.
Crew 9 officers and 46 enlisted.
Commissioned: June 10, 2006, Homeport: Cheboygan, Michigan IMO No 9271054.

WLBB: The W preceding the number of all Coast Guard ships since World War II signifies them as Coast Guard vessels. WLB is the Coast Guard’s designation for seagoing buoy-tenders. The L stands for load-bearing working boat, and the B specifies its size category (big). The LB designates this vessel as a big buoy-tender, and the last B stands for icebreaker.

USCGC MACKINAW (WLBB-30) is a 240-foot (73 m) vessel built as a heavy icebreaker for operations on the North American Great Lakes for the United States Coast Guard. IMO number: 9271054. She should not be confused with a namesake ship, the USCGC MACKINAW (WAGB-83), IMO number 6119534, which was decommissioned on June 10, 2006.
MACKINAW was delivered to the Coast Guard on November 18, 2005 and commissioned on June 10, 2006. In addition to her ice-breaking duties, the MACKINAW will also serve as an Aids to Navigation ship, able to perform the same duties as the Seagoing Buoy Tenders (WLB) of the Coast Guard fleet. Further, she can conduct law enforcement and search and rescue missions and can deploy an oil skimming system to respond to oil spill situations and environmental response. One of the MACKINAW's unique features in the US Coast Guard fleet is the use of two Azipod units, ABB's brand of electric azimuth thrusters, for her main propulsion. These, coupled with a 550 hp (410 kW) bow thruster, make the ship exceptionally maneuverable. The Azipod units also remove the need for a traditional rudder, as the thrusters can turn 360 degrees around their vertical axis to direct their thrust in any direction. The MACKINAW also lacks a traditional ship's steering wheel. Much of the ship’s technology, including the Azipod thrusters, is from Finnish Maritime Cluster. Additionally, the MACKINAW can continuously proceed through fresh water ice up to 32 inches (81 cm) thick at 3 knots or 14 inches (36 cm) at 10 knots. She can also break smooth, continuous ice up to 42 inches (107 cm) thick through ramming.

The MACKINAW got off to a rocky start before being commissioned. While en-route to her new home port of Cheboygan, Michigan, the MACKINAW struck a seawall in Grand Haven, Michigan on December 12, 2005. The accident caused a 10-foot (3.0 m) dent in the bow of the MACKINAW on her starboard side. Shortly after the accident, Captain Donald Triner, the commanding officer of the MACKINAW, was temporarily relieved of duty pending an investigation into the accident. The accident did not delay the ship's scheduled arrival in her new home port; she arrived on December 17, 2005. Captain Triner was later permanently relieved of duty and replaced by Captain Michael Hudson, who was replaced in turn by Commander John Little in April 2006. CDR Scott J. Smith assumed command in July 2008 and was relieved by CDR Michael J. Davanzo in Aug, 2011. In June 2014, CDR Vasilios Tasikas assumed command. In June 2017, CDR John Stone assumed command. The MACKINAW is stationed at Cheboygan, Michigan. It can be seen and toured at Grand Haven's Coast Guard Festival every summer. The ship was also featured on the television series Modern Marvels. Katmai Bay, stationed at Sault Ste. Marie, Michigan, helps the USCGC MACKINAW (WLBB-30) in ice breaking duties.
2019 In service.

In the margin you see a freefall lifeboat and a helicopter picking up survivors. I have been sailing on ships fitted with a freefall lifeboat and in my eyes she are the best system for a lifeboat to get safely and very quickly of a vessel.

Wikipedia gives for the freefall lifeboat:
Some ships have a freefall lifeboat stored on a downward sloping slipway normally on the stern of the vessel. These freefall lifeboats drop into the water when the holdback is released. Such lifeboats are considerably heavier as they are strongly constructed to survive the impact with water. Freefall lifeboats are used for their capability to launch nearly instantly, and high reliability in any conditions. Since 2006 they have been required on bulk carriers that are in danger of sinking too rapidly for conventional lifeboats to be released. Seagoing oil rigs are also customarily equipped with this type of lifeboat.

June 2019 marks the 75th anniversary of D-Day.
On 6 June 1944, Allied forces launched the largest combined naval, air and land operation in the history of warfare. The combined assault on Nazi-occupied France was codenamed Operation 'Overlord' and the Allied landings on the Normandy beaches marked the start of a long and costly campaign to liberate north-west Europe from German occupation.

Normandy was chosen because of its close proximity to the British coast, thus allowing Allied aircraft to effectively support troops landing during the initial phase of the assault (Operation Neptune). Also, the German defences along this stretch of the coastline were less formidable than in the north as the German Command expected the Allies to land where the Channel was at its narrowest.
The invasion was conducted in two main phases - an airborne assault and amphibious landings. Shortly after midnight on 6 June, over 18,000 Allied paratroopers were dropped into the invasion area to provide tactical support for infantry divisions on the beaches. Allied air forces flew over 14,000 sorties in support of the landings and, having secured air supremacy prior to the invasion, many of these flights were unchallenged by the Luftwaffe.
Nearly 7,000 naval vessels, including battleships, destroyers, minesweepers, escorts and assault craft then took part in Operation 'Neptune', the naval component of 'Overlord'. Naval forces were responsible for escorting and landing over 132,000 ground troops on the beaches. They also carried out bombardments on German coastal defences before and during the landings and provided artillery support for the invading troops.
The ground troops landed across five assault beaches - Utah, Omaha, Gold, Juno and Sword. Despite poor weather conditions and fierce resistance from German units the operations were successful and by the end of the day, the Allies had established a foothold along the coast and could begin their advance into France.
D-Day was mostly an Anglo-American effort: British, American and Canadian troops made up most of the numbers, but no less than 17 Allied countries participated on the ground, the sea and in the air. The landings of 6 June 1944 entered history under the now legendary name of D-Day.
Three stamps have a maritime theme.
