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.

About D-Day
The 6th June 2019 marks the 75th anniversary of D-Day, the largest combined naval, air and land operation in the history of warfare. On D-Day, 6 June 1944, Allied forces launched a combined naval, air and land assault on Nazi-occupied France. Codenamed Operation 'Overlord', the Allied landings on the Normandy beaches marked the start of a long and costly campaign to liberate north-west Europe from German occupation. Early on 6 June, Allied airborne forces parachuted into drop zones across northern France. Ground troops then landed across five assault beaches - Utah, Omaha, Gold, Juno and Sword. By the end of the day, the Allies had established a foothold along the coast and could begin their advance into France.
Royal Mail is marking the 75th anniversary of D-Day, and its indelible impact on the outcome of WW2 with this set of stamps and products.
Two stamps have a maritime theme:

1st Class
HMS WARSPITE, part of Bombardment Force ‘D’, shelling German gun batteries in support of the landings on Sword on 6 June 1944. viewtopic.php?f=2&t=9921&p=10275#p10275

Commandos of HQ 4th Special Service Brigade leaving their landing craft and wading ashore on Juno.

I found the photo on the net with the caption: Headquarters personnel of the 4th Special service Brigade, making their way from LCI(S) (Landing Craft Infantry Small) onto “Nan Red Beach” JUNO area at St Aubin-sur-Mer at about 9 am on 06 June 1944 (Wikipedia)

The book The D-Day Ships by John de S. Winser gives for the LCI(S) that this craft assembled Solent area.
The following British craft took part in the landings: the numbers 501-510 and 512-540, altogether 37 LCI(S).

Which craft is depicted on the stamp I am not sure the pennant No is very vague. The number starts with a 5 but the other two numbers which are visible I could not read.
I found later on the D-Day stamp of Tristan da Cunha were the numbers are more clearer that she is the LCI(S) 526 which was built in 1942 by the Itchenor Shipyard in the U.K. She took part in the D-Day landing with her sisters.
Her fate is not known.

The British reworked their need for a raiding vessel into something that could be produced natively without making demands on limited resources. Fairmile Marine had already designed a number of small military vessels that were built in wood and they produced the Fairmile Type H which was another prefabricated wooden design. This was taken on as the Landing Craft Infantry (Small) or LCI(S). One Fairmile "H" still survives a veteran of D-Day and the costly assault on Walcheren, it is a houseboat on the River Adur, Shoreham by sea West Sussex,England. https://en.wikipedia.org/wiki/Landing_C ... ntry#LCI(S)

The number 512,517,524,531,540 was sunk by the landings.
