EDICs have the typical landing craft utility design with a bow ramp and have a large aft superstructure compared to the derivative CDIC.

A sub class, called the Engin de débarquement ateliers or EDA was constructed between the first and second groups but were fitted out as repair craft.

They were powered by two MGO diesel engines driving two shafts rated at 750 kilowatts (1,000 bhp).

The EDIC III type have capacity for 200 t (200 long tons) of vehicles and can carry up to 180 personnel.

The two landing craft are powered by two SACM MGO 175 V12 M1 diesel engines turning two shafts rated at 890 kilowatts (1,200 hp).

They can carry up to 96 troops and 11 lightweight fighting vehicles such as AML 90, Humvees or M113 armored personnel carrier.

[5] Four ships were constructed to similar dimensions and propulsion system to the first two EDIC groups in 1964–1965 and called the Engin de débarquement ateliers or EDA.

Instead of being landing craft, they were equipped as repair and logistics ships for service on overseas stations.

Seven were built by Chantier Naval Franco-Belge, three by the Toulon Dockyard and two by La Perrière in France.
