Nexter's answer to Lockheed's 40mm CTA Turret:
Nexter has been working on a brand new Two-Men Turret based on the Franco-British 40mm Cased Telescoped Weapon System CTWS40.
CTWS uses a rotating breech mechanism and Cased Telescoped Ammunition where the projectile is fully or partly buried inside the propellant.
The Nexter T40 turret is one of the two ongoing projects that use the CTWS40 as the main armament. The other one is Lockheed Martin UK's turret for the Warrior IFV Upgrade Programme / Warrior Capability Sustainment Programme.
Nexter has developed this turret for the French Army's new reconnaissance vehicle project to replace the 6x6 AMX-10RC and ERC-90 Sagaie platforms.
ERC90 Sagaie Reconnaissance Vehicle
T40 is a Two Men Turret with 40mm CTWS as the main armament. The turret structure is constructed from aluminum with add-on steel armor. The turret offers STANAG 4569 Level 4 protection all around that satisfies immunity against 14.5mm heavy machine gun rounds. The turret has a weight of 4.2 tonnes.
From the images it seems that the there isn't a coaxial machine gun rather a 7.62mm machine gun in a Remote Weapon Station (RWS) on the roof.
The commander is located on the left hand side of the turret, whereas the gunner sits to the right of the commander.
The main gun elevation is 45 degrees. I was unable to see a panoramic sight for the commander and this led me to believe that the commander uses the sight in the RWS as the dedicated commander's sight. There are laser warning recievers on four corners.
There is also a situational awareness system consisting of cameras providing all around vision on the sides of the turret. The commander also has a bunch of periscopes around his hatch.
