no, its an extension cover to protect the extended composite from view and damage. There is an extra plate that mounts on top, you can see the mounting bolts there.
Hard to say. I would say some kind of cover for now.

British Army posted a video of the CR3, it gives a slightly better view of the engine deck than the previous videos. Looks very similar to the CR2, of course most engine changes will be internal though. Known/claimed powerpack changes include:
- New engine cooling fans
- Improved fuel injection
- Improved 3rd generation hydrogas suspension
- other unnamed upgrades
I also read somewhere that the engine has new computer controls, but I cant say for sure thats just from memory.
edit: I didnt mean to reply to your post S8IG, sorry

some kind of a powerpack, might be old, might be new.
I’d hazard a guess at new. the old fans have the belt drive and mounts for that on this side from the camera’s perspective, however that could just not be mounted.
its there

Not confirmed.
The only thing that is confirmed is fans.
and radiators
are they?
yep
good spot. Might be new then. The old fans had very pronounced mounts
:shrug: You probably have better idea about this sort of thing than I lmao
i remember seeing only fans.
perspective makes it hard to tell, but they can be the old one. You can not see the slope while looking perpendicularly from that distance

Yep, it isn’t confirmed. I just added it because it has been mentioned quite often.
Once again, this isn’t a 100% credible source, but Military Leak’s article on the Challenger 3 from Army Expo 2024 (published yesterday) states it has improved fuel injection. The rest of the article checks out pretty well, so I’m hopeful its true.
But tbh, the part that the belt is set over looks differently


Much smaller
That whole part looks differently
And here is Cr1

The new one are much smaller
Just me saying, but reduction in diameter of pulley, and bigger metal circle udner it

might suggest increase in RPM of fans
The actual intake portion looks much smaller, with a bigger axle(?) imo. but eh, my eyes can’t be trusted atm lmao. broke my glasses the other day, so I’m sat here in my (prescription) sunglasses looking like someone with more money than sense lmao.
OLD

NEW
