Snowbird 6 IceChallenger 6 aka Snowbird 6 (2002)

Snow-Bird 6 is the first ever land based vehicle to cross the frozen Bering Sea from America to Russia. This journey is only possible in winter when the Strait freezes over and becomes an ice bridge.

It has Tracks and Archimedes screws
The Tracks are used to get some speed on snow and ice
The Screws are used for water propulsion and to clime out of the water onto the ice.

Iguana Yachts Company prototype (2011)

Nice new amphibious concept

The tracks move side ways up for water travel and then
the inside that supports the tracks forms the hull.

Ihtandra 2

Ihtandra 2

Ihtiandra 1 (1979)

Developed by Igor Rikman from Moscow Russia.

Rikman drove this first Ikhtiandr for more than a decade around the Eastern-bloc, approximately 400,000 Km on land and 1,000 Km on rivers, lakes and four seas (Baltic, Caspian, Black, and Barents).

Both vehicles served for camping for a family of five.

Engine: VAZ0-2103
Gearbox: ZAZ-966
Weight:  1100kg Load: 5 persons plus a payload of 300 kg
Hull: aluminium
Waterdrive: water jet -- likely the first civilian use of a water-jet in an amphibious vehicle.

She has an anchor on the bow connected to an electric winch.

Thanks to John for ALL the info!

Ihtandra 2

Ihtiandra 2 (1991)

Developed by Igor Rikman from Moscow Russia.

Rikman drove Ikhtiandr-2 for nine years over 140,000 km by land and several hundred by water.

Both vehicles served for camping for a family of five.

Engine: VAZ - 21213 placed in the rear.
Speed land: 130  water: 16 km/h ??
Length: 5200 width: 2000 height: 1600 mm
Weight: 1450 Load: 5 persons plus a payload of 300 kg

Hull: fibreglass and epoxy body around a square-tube thin-walled steel frame.
The body was filled with 1.6 cubic mtr of PVC foam to provide emergency buoyancy.

It is a 4WD vehicle but the front wheel drive can be disconnected.
The wheels are retracted in the water by a hydraulic device.
The same device makes it possible to raise the vehicle slightly to improve the off-road capacity.

Info was send in by John AND Inna & Eugene Polyakov

Insulaner (1949)

Build by Paul Munig or Manch from Berlin. (Insulaner = German for "islander")

Engine land: radiator water-cooled two-stroke 20 hp
Gearbox: ?
Transmission: driving the front wheels
Engine water: -----  cooled with fresh water
water-propulsion: propeller

The aluminum body housed two.
In the front and rear are foam-filled fins for extra buoyancy.

In the photo is the early version.
That version with very narrow wheels was clocked with a water speed of 70 km/h (?)
The later version has a wider body and a more boot shaped bow.

The top land speed was 130 km/h
There ware plans for a trip around the world, but it stayed at plans.

Both vehicles are lost in time.

Ishikawajima Amphiroll Japan (1967)

Developed by Ishikawajima-Harima Industries

Dorothy is the name of this Japanese amphibious vehicle.

It uses four rotating screws, two screws are counter rotating on each side.

In Popular Mechanics March 1967 there was an article about this vehicle.
Ishikawajima Sumida AMP (1931)

Ishikawajima Sumida AMP (1931)
Ishikawajima Sumida AMP Japan (1931 1933)

Was build by Ishikawajima Motorcar Manufacturing Company
one of the first car manufacturing companies in Japan. (now Isuzu)

The Sumida was the first amphibious prototype for an armoured re-con vehicle.

Engine: Ford type A 4-cylinder gasoline 40 hp
Length: 4000 width: 1600 height: 1900 mm
Weight: 2500 kg
Speed land: 45 water: 9 km/h
Crew: 2 men

Suspension was a copy of the French Kegresse system.
The performance off road was less than expected and it had some engine problems.

It was going backwards in the water, it had a propeller and rudder on the front.

I found it on
Ishikawajima Amphibious Type 92 (1932)
Ishikawajima Japan (1932)

When in 1932 the Type 92 tank was introduced Ishikawajima made an amphibious version. Only a few were made. They saw action but survivors are not know.

The amphibious tank in the photo has 6 boogies and leaf suspension like the Type 92
I give it 80% that it is the right one.
Ishikawajima SR-I (I-Go or Ha-Go ?) Japan (1933)
Ishikawajima SR-I (I-Go or Ha-Go ?) Japan (1933)

SR-I (I-Go) = model 1
It was an amphibious tank that used the Type 92 suspension.
With 8 boogies and leaf suspension.

Engine: air cooled Ishikawajima 6 cylinder gasoline 45 hp ?
Engine: diesel 70 hp ?
Length: 4950 width: 2400 height: 1650 mm
Weight: 3400 to 3700 kg ?
Speed land:
Water propulsion: tracks only but it did had a rudder
Crew: 3 driver, gunner and commander.
Armour: 6 to 12 mm
Suspension: Bell crank

1 prototype only
Ishikawajima  SR-II

Ishikawajima  SR-II

Ishikawajima  SR-II
Ishikawajima SR-II Japan (1934)

SR-II (Ro-Go) = model 2

It had lower and bigger floats and a more boat like hull
The tracks were partly build of type 95 parts
3 boogies and a trailing idler with a bell crank suspension

Length: 4100 width: 1800 height: 1600 mm
Weight 7 000 kg
Water propulsion: 2 propellers
Speed land:
Crew: 3  driver, gunner and commander.
Armour: 6 to 12 mm ?
Suspension: Bell crank with coil-springs

Some production was made. 1 ended in 1945 in Manshuria in Russian hands.

Ishikawajima SR-III Japan (1935)

SR-III (Ha-Go) = model 3 was a remodeled larger SR-II with more and thicker amour.
The goal was an amphibious tank with a big gun! The floats were wider and steering parts of the Ha-Go were used. The hull was partly welded to save on weight.

Length: 4100 width: 2000 height: 1800 mm
Weight: over 7 500 kg
Water propulsion: 2 propellers
Crew: 3 driver, gunner and commander.

A large gun was not possible because then the maximum weight limit set by the army was past.
It went over the 7 500 kg and the army did not want to increase the weight limit.

Production: 2 prototypes ?

After 1935 the Navy took over and
build the Mi-Sha (Type 1) (no info) and then the Ka-Mi (Type 2)
