Could it be possible to have a more mature debate, please ?

Where did this come from ?

EDIT:
 
This 125mm ammo -it's US "black project" of 125mm test APFSDS whit technology of the XM829E1/E2 -so evaluation how good can by Sowiet APFSDS based on build "US 125mm ammo" on best avaibla components. It was XM.... (i will find this marks in my notes and put here).

Oddly enough, the other day I got an email from someone in Jordan looking to purchase engines for a Challenger I.  I don't know why I get these sorts of emails, I certainly don't have a stock of engines in my backyard to sell.
 
It came from someone at raboukh.com and asked:
 
hello sir we need  4 engine diesel rolls royce cv12 tca for tank Challenger 1 
 
Raboukh is a Jordanian outfit from what I can tell.  Their website is unintentionally hilarious.  

Germans wanted to make some profit from BMP-3s of the Greek army. Slav engineering should not be combined with Krupp tech!

Something I came across while looking for something completely different, a patent on kinetic energy projectiles that lengthen after being fired.
 

A quick comparison of the DM11, M339 Hatzav and XM1147 that I slapped together, since they are all programmable 120mm HE rounds that use tungsten pellets.
 

The 35 mm KETF is a very odd round developed for the Royal Netherlands Army. The decision to develop a round with more payload (of smaller tungsten pellets) compared to the already existing 35 mm AHEAD round was the Dutch requirement to have a high probability of knocking out every optic of a T-80U MBT with a single salvo. However in Swiss testing, two 35 mm AHEAD rounds (each with 152 pellets) already were capable of knocking out all relevant optics of a Pz-68 (upgrade prototype), including the gunner's sight, the two openings of the optical rangefinder, the laser rangefinder, aswell as vision blocks of the commander's cupola and the driver. So one has to wonder, if there really is an advantage over the 30 mm KETF round in this regard...

But the one thing that I think is odd in the DTR magazine's article is that they ignore that the Boxer CRV is offered with both options; they speak about possible protection gained by the greater standoff capbility of the 35 mm gun of the Patria AMV, which could equalize the lower armor protection (level 4 vs level 6), but completely forget that one of the two Boxer CRV prototypes has a 35 mm gun, while the other also has Spike-LR launchers...
 
Btw. unprogrammed the 35 mm KETF and AHEAD can penetrate a 55 mm steel plate.

Lets start a thread about the CV-90. Past, present, futur.

The Armored Combat Vehicle Puma started as a privat-venture betwen Krauss-Maffei and Diehl in 1983. The two first prototypes were ready first in spring 1986 with a Kuka 20mm two men turret and second in autumn with a Diehl 120mm mortar turret. 
ACV-Puma was intented as an export armored vehicle of the 16-28 t class. 
 

 
By 1983 original concept, it was offered with two engine options (400/600hp) to cope with the level of armor protection asked.
The running gear was a mixt of both Leopard-1 and 2 components :
- Leo-1 : road wheels, track support rollers, torsion bars and even the driver's seat ;
- Leo-2 : track adjuster, cooling system components and sproket hub.
It was possible to run the engine outside of its compartment. 
 
In 1988, the concept was improved further :
- the class range reached 38t ;
- the engines offer was 440 or 750hp strong ;
- the chassis was now available in two length (5/6 road wheels) and  hight/low profil hull (20cm).

The ACV-Puma was a contender at the Norwegian IFV programme from 1991 and the Turkish 1987 relaunched TIFV programme.
Norway chose CV-90 and Turkey, the AIFV.
(If anyone have information about how it was a serious contender, I'm interested)
It was also evaluated by the Swiss army in 1991. I don't know if it took part to the Char de grenadiers 2000 programme. 
 

In 1983´s concept, the difference betwen the low profil hull and the 20cm higher hight profil hull was obtained by a "box shape vertical raised" rear compartment. With the 1988's design, the front slop is now different to achieve a better ballistic protection. 
 
When considering documentations of this period, it's important to note the mine/IED protection was not a priority like today. 
 
I'll post soon a scan showing general layout of the troop compartment. It's a Marder/BMP old fashion one with soldiers facing outside. 
 
Even if it was not a success at exportation, I think ACV-Puma must be known because of both :
- the outdated combat beliefs of the 80's (still vigourous today) ;
- and advanced proposal  such as the differential hull length from the drawing board. 
 
I have a question :
Does anyone known if a 6 road wheels chassis was ever built ?

There have certainly been a technological transfert between the SNPE and Kaman but the BS-G2 bricks used on the AMX-30B2 Brenus are thicker than the ARA tiles and in addition, provide protection against armor-piercing projectiles fired from medium-caliber autocannons.

And the period is plenty of very interesting news.
