Underway on USS America

This is simply a glorified LPH(Iwo Jima class) with no well deck flexibility will be lost.

Bring these back


Flood victims could use the help and so could our beach landing military troops. You’ve probably seen them hauling tourists around the streets of America’s biggest cities, but in spite of that carefree utility, the wartime history of the “Duck” is one of significant import. In April 1940, GMC Truck Engineering began to build a prototype of model DUKW353 2½-ton 6x6 amphibious cargo/troop carrier truck for the U.S. Army. After completion in June, that prototype passed Army acceptance tests and a purchase contract was issued. Production started on Nov. 10, culminating a very short concept-to-production period. This model was nicknamed the “Duck” because its coded serial letters were “DUKW.” The first model DUKW353 “Duck” trucks were delivered in late 1943. The chassis was based on model CCKW353 with high forward controls. A central tire inflation system was available, which allowed the driver to adjust tire pressure from his seat. Lowered pressure provided better flotation and traction on soft ground. Initially, Ducks were built on Chevrolet’s Plant 2 assembly line in St. Louis, which previously built buses. (131,733 GMC trucks were produced that year, all of them military vehicles.) Loaded with troops and fighting equipment, Ducks were part of the first waves of assaults from New Guinea to Normandy during World War II. And after those beachhead ballets were won, theses versatile vehicles continued to work, transporting tons of supplies from ships at sea to inland depots. After playing an important role in the landing in Sicily, Ducks were used by the hundreds when the British invaded the “toe” of Italy. Then as Allied Forces began closing in on the Axis, Ducks helped to make successful landings at Salerno, Naples, Anzio and Nettuno. They were also used extensively at Tarawa, Kwajalein, Arawe, Hollandia, and Saipan in the South Pacific. For navigation on the high seas, the Duck was designed with a 31-foot steel hull that surrounds the truck frame assembly. The driving power was switched from the wheels to a rear-mounted propeller with the flip of a lever. The rudder and front wheels were steered by the same mechanism. To keep the hold “high and dry” when the water was rough, the Duck had a “surfboard” at the front, a tarpaulin top and powered bilge pumps. The chassis and wheels gave the vehicle additional balance and stability as well. The Duck could reach speeds upward of 50 miles per hour on hard-surfaced roads, but those were a luxury in both theaters of the war. The vehicle was equipped with a unique tire inflation control system -- innovative engineering for the time -- that allowed drivers to adjust the tire pressure to give the best possible traction for whatever terrain they encountered. And as the Nazis retreated eastward, the Duck’s half-boat-half-truck capability came in handy, allowing the vehicles to cross waterways where bridges had been destroyed. In March 1944, production of a limited selection of medium- and heavy-duty trucks for civilian use resumed under the control of the U.S. War Production Board. Those trucks were available only to operators certified worthy by the WPB. That year, GMC received the Army-Navy “E” Award for Excellence in the war effort. The U.S. Army considered the GMC 2½-ton 6x6 the best trucks in service during the war, and the GMC “Duck” as the most outstanding of new ordnance weapons. During World War II, GMC built a total of 583,925 multi-drive military vehicles, including: 528,829 6x6 trucks, 21,147 Ducks (in Chevrolet’s St. Louis plant) and 32 armored cars. Fifty-nine U.S. War Department contracts were fulfilled plus contracts with Great Britain, France and other allies. The value of GMC military sales during the war totaled $1.5 billion.

Harriers have been retired

Someone forgot to tell the Marines at MCAS Yuma.

[fella]

That’s a lot of assets in one spot.

[SandRat]

Read up on the DUKW amphibious truck.

[fella]

Saw DUWK on The College of the Ozarks campus just a little over a week ago. They tour around Branson and the school is on the tour.

[SandRat]

The WWII Army DUKWs sure could be used by the 'Cajin NAVY' of Louisiana to help the flood victims.

[wbarmy]

True, but the USS America is 250 feet shorter than the Nimitz class.

[sean327]

Not yet. The AV8B will remain operational until at least 2020. VMA-214 and VMA-311 remain Harrier squadrons in Yuma AZ. VMA-211 transitioned to the f-35 and became VMFA-211 6 months ago. VMA-513 was disbanded and VMFA-121 transitioned from the F/A-18 to the F-35 18 months ago and moved from Miramar to Yuma. None of the Cherry Point AV8B squadrons have transitioned yet.

Sure, and half the displacement. It's all relative. We forget how much smaller ships, planes, etc. were a couple of generations ago.

I just looked it up, BTW ... USS America displaces about 5000 tons more than the French aircraft carrier Charles de Gaulle.

[tarawa]

I still don’t understand why they did not change the designation when it is really a separate class of ship from the “real” LHAs. Without the well deck, makes it a bit higher dive when swim call goes out....

[RollingThunder]

You are pf course correct, but that was a different time. In today’s world, with the dangers, especially with threat of radical Islamic terrorists and their allies. The need for special landing craft is apparent. I am not saying that the LHA-6 is not useful. But that it has major flaws do to its lack of a landing deck.

And other amphibious platforms don't have USS America's ability to land large numbers of troops behind the beach as rapidly. Different platforms fill different functions. Let's face it. In the event of an amphibious assault the U.S. is not going to commit a single battalion landing team. They are going to move large numbers of troops on multiple amphibious ships, some with landing docks and some without. The America will operate as part of that task force.
