The EWK M2 is an amphibious bridge and ferry vehicle designed and built by Eisenwerke Kaiserslautern (EWK) in West Germany. Known in its main version as the M2B 'Alligator', it was used by both the German and British armies for close to 30 years, until it was replaced by the M3.

Design

The M2 is a large four-wheeled vehicle about 11.3 m long and 3 m wide on the road, weighing around 22 tonnes. Two side pontoons fold onto its back for road travel and swing out for use in the water, widening the vehicle to about 5.9 m. The front and rear axles are hydraulically adjustable in height, which helps off road and lets the wheels be drawn right up into the hull when swimming. In the water it is driven by a central steering propeller and two propellers in the pontoons. Each of its two Deutz air-cooled diesels (about 178-180 hp) can drive the wheels and the water propulsion at the same time.

On the road it reaches about 60 km/h and has a range of about 1,000 km. As a single-bay ferry it does about 14 km/h unladen and 13 km/h with 12 tonnes aboard; a three-bay ferry carrying MLC 60 loads makes about 11 km/h. A small crane (600 kg at 2 m) and a winch are fitted.

Use

A single M2 serves as a ferry with a 12-tonne payload. Several can be coupled side by side into multi-bay ferries for two or three vehicles, or 10 to 30 units can be joined into a bridge rated up to MLC 60, usable in currents of up to about 3 m/s. When the Challenger 1 tank entered service, British vehicles were upgraded to M2D standard with strengthened ramps, air bags and compressors. In German service the M2 was withdrawn in 1996 when the amphibious engineer battalions were reorganised and the M3 took over.

The M2 also formed the basis of the ALF-1 amphibious fire appliance. After military service some vehicles were sold on: one advertisement offers a demilitarised M2 with full specifications, and another offers two 'AMF' amphibians with the same dimensions and engines that had been coupled together to carry a tunnel-dredging machine on an artificial lake in Spain.
