Christy M1923 in water
Christy M1921 (1921 to 1923)

Christies Schwimmpanzer, USA.
The first amphibious self-propelled gun in the world.

It is not a 6x6, only the rear axle is driven, the front wheels can steer.
If the steering is locked tracks can be used. An extra propulsion mode was to connect the rear and mid axle by an external chain.

Engine: 6 cylinder 90 hp Christy in the rear
Gearbox: 3 speed
Weight 6500 kg.
Road speed on wheels 50 km/h.
Off-road speed on tracks 28 km/h.
Water speed 12 km/h.

In 1922 it was rebuild in to the M1922 with a bigger gun, more free board and a 4 cylinder engine.
The weight was 6.750 kg.
The rear axle was raised when tracks were used.
Later more armour was added to the M1922.

!n 1923 a make over was done with a fourth axle
a 75 mm gun, coil suspension on 3 axles except the driven rear axle
that was still to be raised when tracks were used.
The 2 rear wheels where larger than the front wheels.

On the rear where the same two 3 blade propellers that were used with the M1921and M1922.

In the end the M1923 had a sort of closed hull and that makes it also the first amphibious tank.

It floats because there is a thick foam layer under the car.

Water propulsion comes from a Yamaha 650 jet ski in the trunk.

This vehicle was for sale on Ebay.

Chrysler LVW-XI (1958)

LVW = "Landing Vehicle Wheeled".
  It was designed for use in/after a nuclear war.

It was a project of the United States Marine Corps and BUSHIPS. First it was build by Borg Warner, in Kalamazoo, Michigan then Chrysler took over. (after 1963) How, when and why is unknown.

The task was to provide a one-hour time transport for men and materiel from ships 56 km off shore and carry a 5000 kg load up on the landing site and down the highway.

Engine: Lycoming gas-turbine 1500 hp
Gearboxes: XX
Speed land: 56 water: 56 km/h
Maximum speed at FAC sea 67 km/h on the Potomac River.
Water propulsion: two propellers.

The wheels and propellers are mechanically driven through a series of gearboxes and drive shafts. The wheels have portal-hubs and can be moved upwards to minimise drag in the water.

With the vehicle in the water and the wheels retracted,
the next step was to extend the side planing plates. (mounted behind the rear wheels) That provided more planing area to get her up out of the water.

The prop shafts struts are secured to the aft planing plate.
In photo 5 in the up-most position.
That aft planing plate is hinged at the front edge and pushed down hydraulic so that the trailing edge is level with the bottom edges of the hull sides. That provides even more planing area and puts the props deeper into the water to reduce cavitation damage while absorbing the 1500 horsepower produced by the gas turbine engine.

Chrysler LVH-XI-I (1963)

Chrysler LVH-XI-I (1963)

Chrysler LVH-XI  (1963)

LVH = "Landing Vehicle Hydrofoil"
Build by Lycoming that was bought by Chrysler (1960?) it is listed here.
There are two types of hydrofoils:
1- fully submerged hydrofoils
2- surface-piercing foils (sliding partly on top of the water)

The submerged hydrofoils need a control system to adjust there angle to keep the vehicle on the same hight above the water. In the time before the computer a hard nut to crack.
When air comes under the foil, this happens when a wave hits one side, ("venting the foil") then it looses lift and the vehicle leans over to that side. This in combination with hydraulic leaks made the LVH a project were Chrysler found his Nemesis.

Engine: Lycoming TF 1460BIA gas turbine 900 hp
Length: 12 000 width: 3550 height on wheels: 3660 mm
Speed land: 64 water: 67
Load: 5000 kg

The wheels were mounted at the ends of struts like those of an air-plane. On land the hull was lowered to make loading more easy.

2 prototypes were build. LVH-XI-1 and LVH-XI-2

Top photo and much info George McClellan.
Second photo enhanced from s#!t by me with GIMP ;-)

Both the LVW and the LVH can carry 5000 kg at 50 km/h
But then the hovercraft (
LCAC) came into view.
It can carry over 50 000 kg at a speed over 100 km/h

The production model was LCAC and it used four 4000 hp turbines.
The Navy ordered about a 100 of them.

Chrysler Marsh Screw Amphibian

Chrysler Marsh Screw Amphibian
Chrysler Marsh Screw Amphibian (CMSA)(Amphiroll) (1964)
Same principle as the DAF/Bakker (1960) Amphiroll.
But with a lesser steering system.
But Chrysler owned the patent rights. So exit DAF/Bakker.

The Marsh Screw was propelled by two large Archimedean screw-type devices
that run on the length of the vehicle on each side.

Engine: Chrysler 225 cubic inch, 140 hp, 6 cylinder gasoline
Gearbox: automatic
Speed mud: 22.5 water:13 snow: 32 km/h

The counter rotating screws driven through an automatic gearbox propelled the vehicle through water and marsh terrain adequately, but failed miserably on soil surfaces, especially sand. The average maximum speed attained on test lanes was a meagre 2.5 km/h.
Steering was also not good with the straight mounted rolls.

On hard pavement the only way to operate was to roll side ways.
But without steering as the "DAF/Bakker".

Chrysler MOFAB

Chrysler MOFAB
Chrysler MOFAB (1962) Mobile Floating Assault Bridge/Ferry

The hull is designed to give stability in the water without the use of (inflatable) pontoons.

Engine: Detroit Diesel V8-7.1
Length is 14 500 width: 3600 height: 3500 mm
Weight: 27 000 kg

It is 4 wheel drive with retractable wheels and on the road it is steered in the front. In the water it is propelled by a very large semi out board and steered at the rear by a very large steering wheel.

The tread-way, not there any more in the first photo, turns 90 degrees and opens to meet the next unit tread-way. MOFAB's can build a 30 feed bridge in 30 minutes without water preparation. 4 MOFAB's together can carry 70 ton.

The first photo was send in by Laura from Kansas.
The Mofab is still a funktion amphious vehicle but it lost her bridge ferry parts

The second photo is from a Chrysler advert.

(3-  The green one on the photo is number 6 and is in private hands)

4 wheel drive, aluminium body and 4 wheel independent suspension.

Engine: 318 V8 diesel 150 hp
Gearbox: automatic Dodge transmission with the internal parts of a racing transmission.
Speed land: 80 km/h
Weight: 2727 kg
Water propulsion: tires

Chrysler - River Utility Craft RUC (1969)

Disappointing results in the Marsh Screw tests did not end ambitions for screw-type mobility systems.

In 1969 Chrysler produced the Riverine Utility Craft (RUC) for the Navy. The RUC travelled on two aluminium rotors, 39 inches in diameter.

Engine: twin  Chrysler 440-cubic-inch auto-mobile
Length: 7000 width: width: 4750 height: 3900 mm
Weight 5900 kg
Speed land: 50 km/h water: 28 km/h (WES test program in south Louisiana)

Speeds on firm soils proved disappointing, 23 km/h maximum and only 6.5 km/h in MUCK.

Screw vehicles failed big time compared with the more conventional wheeled and tracked vehicles.

It is NOT a full colour fantasy of an artist.

The vehicle was build by the Chrysler Defence Operation Division.
But it was only a full size mock up specially made for an military exhibition.

Chrysler XM 410 (1958)

Amphibious 2.5 ton truck

The XM410 was built around 1958-1959 by Chrysler Co.
6 prototypes were made.

Engine: 361 industrial
Gearbox: push button automatic transmission
The front 4 wheels do the steering
Brakes: disk brakes on all 8 wheels
Water propulsion: with the wheels
The bodies were made out of aluminium.
They are 8x8 with full independent suspension on all wheels

The XM 410E1 was also built by Chrysler around 1965 25 trucks were built.
They use a Continental multi-fuel engine

The first photo is from a Chrysler advert.
The last 2 photo's are of a nice XM 410 modification. :-)
