The Jeanne d'Arc is the Porte-hélicoptères [helicopter carrier]
that has replaced the traditional cruiser of the same name as
the naval training ship of the French Navy in 1964. Jeanne d'Arc
has no sister ships, and has not been much altered in her years
of service with the French Navy.

Of 182 meters length and with a displacement of 12,000 tons, the
"Jeanne d'Arc" is propelled by four boilers supplying two turbines
with vapor, and can reach a speed of 28 knots (50 km/h). Its armament
initially consists of its capacity of carryings of helicopters of all
types, which constitute its true system of weapons. The "Jeanne d'Arc"
also has six Exocet sea-to-sea missile launchers (offensive armament antI - ships)
. The two triple Exocet missiles are fitted on the deck in front of the bridge.
The four turrets with 100 mm guns are used for self-defence anti-air and anti-surface.
Other euqipent includes a sonar (detection anti- underwater and torpedes) as well
as electronic warfare equipment (detection and identification of the electromagnetic
emissions).
