Subjects for discussion to include wheeled and tracked amphibian vehicles such as the LVT, LVTA, LVTP5, LVTP-7 (AAAV-7), and the recently cancelled EFV (aka AAVX). 

While the real AMTRAC and AMTANK vehicles were rather short-lived due to their light construction, they did serve their purpose in getting the troops ashore and providing immediately available fire support until tanks could be landed.

The French made extensive use of LVTs in Indochina, including versions mounting the 40mm Bofors:

Jon,

Thanks for sharing that image.  This is the first image time I have seen of that version which provided sufficient detail of the turret to actually see the thing.  The addition of the two M2 Browning .50s mounted with the Bofors is a very interesting arrangement for the AMTRAC.

Ah, the old motion-sickness inducing tuna boat...man does that beast need to be replaced.  Tall and slow, two great qualities in a target. Whatever is next needs to carry a little more punch than a 40mm Mk-19 and a M2 HMG.

According to one of our members that is currently on active duty and wearing a the uniform of a United State Marine (yes, LemonJello, I am talking about you) the term "Tuna Boat" comes from the very ungainly and high profile of the LVTP-7/AAAV-7 when seen out of the water.  I would have to agree that when viewed on the beach or in the motor park the vehicle does take on a profile that reminds you of a fishing boat in some ways. 

Don't be bringing any apricots on board, either...

Mount the turret from the Saladin or the M113 FSV on the LVT(A)-1 or LVT(A)-4 to create a slightly different fire support vehicle.

Good idea. You could also use the aluminium turret from the Scorpion/Scimitar: the lower weight would probably be an advantage. or another idea: how about a "super" USMC version with a Chaffee turret?

Nickname is explained further back in the thread.

The inflatable tube skirt was to deflate and be covered by hinged panels, from what I can
ascertain it had more in common with the inflatable skirts of the Bell ACLS, than a standard
ACV skirt.

Replace the turret on the LVT(A)-4 or LVT(A)-5 with the turret from the Alvis Salidin Armoured Car.  Something that might be an economical alternative to buying a whole new fleet of amphibious vehicles for a country that is looking for an affordable upgrade to their AMTRAC fleet.

The demilitarized hulls with running gear and drive trains go on auction to the public. What do you make?

The Marine Corps will keep its fleet of decades-old Amphibious Assault Vehicles out of the water except in emergencies, the service announced on Wednesday.

The water ban on the AAVs makes permanent restrictions the Marines placed on the 1970s-era vintage amphibious armored personnel carriers following the AAV incident in 2020 that killed eight Marines and a sailor in a training incident off the coast of California and led to several subsequent investigations.
