Cockerill Weapon systems - Which ones, what weapons and what ammunitions

I found a video of this variant; the turret reminds me of the French AML-90’s, but it’s different. It’s not the Brazilian turret either, it might be a Chilean one.

As a side note, the source also allegedly depicts a PT-76 fitted with a Cockerill Mk. III gun.

CMI Defence included the PT-76 among the vehicles covered by its Weapon Systems Modernisation Programmes . The programme presented a range of potential upgrades intended to improve the performance of existing weapon systems.

For the PT-76 specifically, the brochure lists general turret reconditioning , replacement sights , direct day and optional thermal sights , I² night vision , a laser rangefinder , and, most notably, the replacement of the existing gun with a Cockerill Mk3 gun .

The table also indicates that CMI offered this gun replacement for the PT-76 alongside a similar upgrade for the Alvis Scorpion. The brochure does not, however, provide further details on the exact PT-76 configuration, ammunition, or whether a Cockerill Mk3-equipped PT-76 was actually produced.

Indonesian? This is a proposal for the Portuguese Army, I believe in 2007.

Correct, but this vehicle was later also used for the Indonesian army trials, where it succeeded and was subsequently made into the

This exact prototype from 2007, with the CT-CV turret, saw trials in Indonesia? Did Cockerill just have it in storage the whole time or something? And there are no photos of these trials?

that vehicle’s gun barrel is just a mockup

We dont have a lot of info about it but I’ve also surmised from observation about it here:

No, I mean that Indonesia (Pindad) ultimately worked further on that vehicle. The hull was returned to Belgium and later used in the Pandur II 3030 trials with the laser guided rockets, while the turret was used on patria chassis in Finland and Poland.

Yes, there are vehicles in this list that have a mockup gun/turret, like some of the Turkish vehicles too. They could be counted as partial prototypes or (ongoing) projects.

With CT-CV turret though? It seems misleading to label it as an Indonesian Army vehicle even if Pindad did “work on it” at some point because that ignores the originally intended recipient many years prior.

I can remove that label and I’ll just add a small info block under it, but I’ve mostly left context like that out because of the character limit on a single thread/post.

Historical note: This Pandur II FSV fitted with the CT-CV 105HP turret was originally developed as a 2007 proposal for the Portuguese Army, rather than as an Indonesian Army vehicle. The vehicle was later associated with Pindad/Indonesia , which continued work on the design to the Pandur II FSV (Cockerill 3105). The original hull was subsequently returned to Belgium and was later used in trials of the Pandur II 3030, while the CT-CV turret was separately used on other chassis for trials in Finland and Poland.

Just was confused on why you were calling it Indonesian when there are no photos of it in Indonesian service, testing or otherwise.
