Many years ago I read about this project (end of 70s or early 80s). It was a short-range small caliber rocket launcher, destroying low flying targets by salvo of unguided rockets. A box with 48 tubes was installed in the turret similar to the turrets of modern AA guns, with integral radar system etc. AFAIR the Javelot was a land version mounted on the tracked vehicle and the Catulle (?) a naval version with a more tubes (64 or 96?). The rockets were small (37 or 40 mm?) but pretty fast (>1000 m/s) and the effective range was 2-3 km.
Maybe someone have more information about this weapon?

I found no information in English. I hope you learn well your French lessons:

Le système lance-roquette Javelot

Le système d’armement anti-aérien Javelot consistait en un lance roquette
multitube, doté d’une grande puissance de feu (64 tubes) lançant par effet canon des
roquettes de 40 mm d’un poids légèrement supérieur à un kilogramme (1.030
grammes) à une vitesse initiale de V0 = 1100 m/s. Ces roquettes pourvues d’une
propulsion additionnelle sur trajectoire et stabilisées par empennage atteignaient 1100
m/s, soit à 2.000 mètres une durée de trajet de 2,8 s. La charge de 400g de la tête
militaire pouvait être déclenchée par une fusée â impact ou une fusée de proximité.
Le tir s’effectuait par salve de 8 roquettes, « organisées » dans l’espace (directions de
tir différentes) et répétées dans le temps (départ successif de salves). L’originalité de
ce principe et la qualité de la conduite de tir sont à mettre au crédit de Thomson-CSF.
Il est reconnu que, pour un même nombre de coups tirés, le tir de salves, s’il est plus
contraignant pour l’affût que le tir en rafale, est plus efficace. L’organisation de la
salve consistait à choisir les tubes lanceurs dans l’ensemble multitube, en fonction de
la présentation de la cible avion (avion vient, avion défilant, etc ...) Les études
Thomson-CSF ont été conduites par MM. BILLOTET et GUILBAUD. Le lance roquette
et les munitions furent étudiées par THOMSON-BRANDT sous la direction de
M.CREPIN..

Le programme, qui était relativement important (environ 100 MF) a été
financé par les États Unis (service de Chicago) au titre des échanges «two way street»
entre la France et les USA , en ce qui concerne le développement exploratoire et la
maquette probatoire lance roquettes multiples. Le programme suivi en France par la
DTAT (ICA de BERNARDI), se déroula de 1970 à 1973 mais ne fut pas poursuivi.

From Bill Gunston "Enzyklopädie der Raketen & Lenkwaffen":

"Project for a close defense weapon, based on a spin stabilised 40mm
rocket with a length of 370mm and a range of 1500m. The magazine
was housing 64 rockets, that could be fired in salvoes of 8, 16, or 32 rockets,
aimed by the integral radar or an optical system.The magazines could be
replaced within 30 seconds, kill probabilty against a target in 1500m
was expected to be around 70%. The design was drawn in 1978 by Thomson-
CSF as the main contractor, a navalised variant was known under the name
Catulle"

A resurrected Javelot might be a very handy (and relatively low cost) anti-drone system. The naval version would also definitely have potential in the current maritime threat environment, especially with some of the poorly designed platforms out there today which are in dire need of firepower improvements, e.g. LCS.

I try my Best on Pepe Rezende French Text

the Anti Aircraft system Javelot consist multitube rocket launcher
Wat give big firepower (64 tubes) launch by gun effect
the rockets of 40 mm ø ( 1,57 inch ø ) and weight of 1030 Gram ( 2,27 US pound)
they have rocket engine with initial velocity of 1100 m/s. ( 3.609 ft/sec)
and make 2000 meter in 2,8 seconds and is spin stabilised
a Charge of 400 Gram (0.881 US pound) of explosive
ignite on impact or proximity
rapid fire goes in salve of 8 rockets "organised" in space
means several direction of trajectories to target
the system can fire of several salve successively

Originally this Principe goes to Thomson-CSF
based on study by MM Biollotet and Guilbuad
the Rocket launcher and Rockets were build by Thomson-Brand
under direction of M. Crepin

this important program (100 million Fr. franc) was finace by USA
under a US French exchange program in multitube launchsystem
the Javelot program R6D was by DTAT (ICA de Bernardi) 1970 to 1973
but not further R&D after that

A few notes on Javelot from the DTIC archives:

First, interesting to read that USA was involved with Javelot development:

The French Javelot, a short-range, low-altitude, surface-to-air, multiple-rocket antiaircraft weapon,
and the FRG Fiakpanzer Gepard, a twin-35 mm antiaircraft gun system, are both interesting candidates
for an offset package.

The United States is working with France in developing the Javelot, and we are testing the Gepard.

Desired dispersion of Javelot:

a.
Javelot, which is reported to have the objective of achieving RAP dispersions
competitive to gun fired unboosted projectiles, should be critically observed in
development and demonstration firings to determine the feasibility and possible
difficulties in achieving these objectives.

I can recall a similar in general Swedish concept from the '90s called Retaliator.Could anyone give me more infos on the swedish system?
