AAAV prototype AAAV prototype

Advanced Amphibious Assault Vehicle

The AAAV prototype on display at AMTRAC Museum, Camp Del Mar, USMC Camp Pendleton, CA, USA.

This is a tracked version that could also operate on water. The propulsion unit is placed in a box at the rear with three water jets. This box then lowered in the water and that made the vehicle act like an over-sized Jet ski.

The person standing in front gives reference to the size of the prototype.
It is 75% of the proposed vehicle.

The real AAAV will be capable of transporting 18 Marines and a crew of 3 over water at speeds up to 29 mph, on land speeds up to 45 mph.

Alligator (1937)

The Marine Corps Amphibious Tractor. Developed during World War Two to deliver Marines over the coral reefs of the Pacific islands.

The Gator was invented in 1937 by Donald Roebling for rescue missions. A great hurricane swept through Florida Everglades in 1935 and then it was not possible to rescue people.

The first Gator had:
Engine 92 hp Chrysler
Speed land: 40 water: of 3.5 km/h

The second Gator had:
Engine: Ford V-8 Diagonal cleats attached to the tracks
Speed water: 8.5 km/h
Weight: 4000 kg

The third Gator had an lighter aluminium hull
Speed land: 32 water: 14 km/h

On 2 Okt 1937, the vehicle was presented in Life magazine.
The Alligator amphibian tractor is the predecessor of every landing vehicle with tracks.

The for military use redesigned Roebling Alligator is the 1941 LVT 1

Stollie Prototype

last Stollie of the production line
Alvis Stalwart Proto 1960

The PV 1 is not a true swimmer, it can only float covert with tarps.
In the photo a later PV 2, at first it had a heavy sliding Hatch.
The prototypes ware based on the 1959 Salamander fire tender FV651
The idea was to use the same (spare) parts.

In 1961 the PV3 had a dual hatch and auxiliary air lines for trailer brakes and an Allison automatic gearbox.

In 1963 production of the MK 1 (FV 620) started

In 1966 the MK 2 (FV 620) came into service
It has bigger windows and the weight is 600 kg more.

And on the bottom the last Stollie of the production line in 1971.

Alvis Stalwart DIESEL (1990)

British Stalwart MKII cargo vehicle with crane, 6X6 5 ton diesel amphibian

Also known as (FV622 High Mobility Load Carrier).

This is one of the two prototypes that the Brits had converted to diesel with a Perkins Phaser engine.

It has the same horsepower but increased torque and it turns the same RPMs as the original engine.

Cost to do the R&D and the conversion to diesel was $125 000 per vehicle.
Super Stollie Alvis Stalwart Super Stolly (2000)

The Super Stolly was the exclusive creation of Land and Seas tours. The Super Stolly was without a doubt the most awesome amphibious tour vehicle ever built!

The Super Stolly is a heavily modified Alvis Stalwart MK 2 purpose rebuilt for amphibious tours.

    Mounted crane;
    Aircraft crash recovery;
    Radio rebroadcast stations;
    Casualty evacuation.

Engine: water cooled 1896 cc Volkswagen Diesel 78 pk
Gearbox: torque convertor, VW/Audi Automatic 089 with three forward and one reverse.
Differential: 1 that drives 2 drop gear reduction boxes, Ratio: 3.37 : 1.

That means it is army amphibious, it does not sink in still water.

Supacat became an independent company,
The Alvis history is to complicated to list here.
The photo on the bottom is the cat I hate, it is a driven by a Robot.
What is the fun in that?

Diamond mining Alvis Stalwart (Stollie) Amphibious self contained diamond mining vehicle. (2000)

This vehicle is a totally self contained unit and was originally designed to mine the rivers of Angola. Besides the rather obvious crane, there are also 5 winches, a drilling head and motors driving the various separators and vibrators.

It is a STOLLY :)

Al FAHD AL FAHD (2000)

Designed and built in Saudi Arabia and is in production for the Saudi Arabian National Guard. It is an 8 wheeled armoured vehicle. Wheels were selected rather than a tracked system because they provide better maneuverability and higher road speeds. A hydraulic amphibious system is available as an option. The maximum amphibious speed is 8 km/h The hull is water-sealed and airtight.

Alligo Alligo (2008)

It is more than a Croco clone.

Made in Germany.
It has four wheel steering and four wheel drive through a hydraulic gearbox.

Send in by Jose who is working in Argentina to develop an articulated vehicle similar to this.
