FAMAE Piraña I 6x6 HVMS

History:

The construction of the Chilean Mowag Piraña was carried out by Industrias Cardoen and FAMAE (Fabricas y Maestranzas del Ejercito de Chile) in the early 1980s. Industrias Cardoen was a Chilean defense company, owned by Carlos Cardoen. Chile was one of the few countries that had Mowag’s license to build the Piranhas locally, thus building several of these vehicles in different configurations and different types of weapons. This version of the Chilean Mowag Piranha was built by FAMAE and is armed with the 60 mm IMI HVMS (Hyper Velocity Medium Support) cannon of Israeli origin that were obtained by Chile in the 1980s when Chile purchased the M-50 and M-51 from Israel. Later in 1983 the M-50 and the new cannons arrived in the country, then Chile armed its M-50 and M24 Chaffee with the Israeli cannon.

In 1992, a military fair was held in Chile where various companies from around the world showed their military vehicles. Among the companies that made their demonstrations was the Chilean national company FAMAE, belonging to the Chilean army. FAMAE showed two different versions of the Piranha vehicle built by them under license in its 6x6 and 8x8 versions, the 6x6 version was amphibious since it had propellers in the rear of the vehicle, it also had the turret manufactured by Israel Military Industries installed that was initially built to arm the Israeli M113 Zelda HVMS vehicle, the turret was capable of resisting projectiles of up to 14.5 mm which was impressive considering that turrets from other manufacturers only resisted up to calibers of 7.62 mm, the turret was armed with the 60 mm HVMS (Hypervelocity Medium Support) cannon capable of firing APFSDS-T, within the technical specifications of the turret, a laser rangefinder and a ballistic computer are also mentioned.

Turret Features and Specifications

The cannon weighed 700 kg and as its name indicates, it was capable of firing APFSDS-T ammunition at high speed with a muzzle velocity of 1,620 m/s that could penetrate 120mm of armor angled at 60 degrees from a distance of 2,000 meters, which gave the new version of the Chilean Piraña a great anti-tank capacity. There was also supposedly a test where this gun managed to penetrate the side armor of two T-62 side by side at 2000 m, which would be ideal since at that time Chile had to deal with the T-55 of its neighbor Peru in the face of a possible conflict, this being the reason why this gun was installed in most Chilean tanks. It could also use high explosive ammunition that was used more for the destruction of bunkers and other objectives.

The new turret as mentioned above was designed by IMI to use the new gun on Israeli M113, this new turret was operated by 2 people, the commander and the gunner, the commander was located on the left side of the gun where he could operate a machine gun located above his hatch and on the right side the gunner. It Is known that this turret had a manual reload mode and an automatic one, but it is not known for sure which of the 2 systems was finally implemented in the Chilean Piraña. The turret of the Chilean Piraña also carried two sextuple launchers of smoke grenades as can be seen in photos.

Details of the new turret

Finally, it is unknown what happened to this prototype, although it is most likely that it did not receive purchase orders either from the Chilean army or from any foreign country, so serial production of this variant did not occur. Currently the Chilean army still continues to use the Piraña 6x6 so I had the opportunity to record the interior of one of these vehicles, below I leave you the video.

We could say that this Chilean vehicle would be the equivalent of the premium Italian AUBL/74 HVG since the gun is practically the same and the characteristics of the vehicle as well, so the Piraña HVMS would be 7.7, just like the Italian

I think it would be perfect in Israel since the turret and cannon are from that country, or in a future Latin American tree

I share this photo that has more details about the ammunition and the HVMS gun, you can see the HE round, they also mention the new Israeli turret

Just adding this here: Chilean Piranha 6x6 with Engesa ET-90 II turret mounting the EC-90 cannon (Brazilian-produced Cockerill Mk. 3), as seen on EE-9 Cascavel.

Chilean ones should be in Israeli TT as they brought IMI version of system.
HVMS guns were lighter than OTO-MELARA 60/70 because of different breech and recoil system design.

At least the 4 Chilean vehicles that had this Israeli cannon should be in the Israeli tree since they are unique and have ties to Israel. How much did the Italian cannon weigh?

Update:

I added new information about the characteristics and specifications of the turret and added a new photo of the vehicle where you can see the depression of the gun.
