Thats more than the Reaper ?
We only have
your highly-unreliable assertions to go by as to Altius-M's wholely
imaginary payload. And it may never become operational, but given it's Russia it just might get there as they operate all sorts of outmoded junk. And we sure can't, don't and won't be trusting any official Russian claims as you so glibly seem to, as they're notoriously hyped and wildly optimistic, typically over-promising and characteristically hopelessly under-delivering, if anything is delivered at all.
But besides that, the 'Altius-M' contraption is claimed to be a "
Heavy UAV" so you'd naturally expect it to have a hefty payload, plus outstanding altitude range and radius performances--like say, an MQ-4 for instance.
Whereas
according to you the Altius-M will have a range of ~2,000 km, and it's now been independently established that the current engines are certified for a maximum altitude of 25K ft which is comparatively pitiful altitude for what claims to be a "Heavy UAV", in 2018.
But then you claim there's another engine coming ...
oh, you just wait! ... you'll all see!
And you
then compare it to a Reaper, which is
not a "Heavy UAV", it's just a fairly small, light tactical UCAV, which has phenomenal payload, altitude and range performances, and can perform ISR, targeting or BDA, while delivering LGBs to regional ranges, day after day, and can keep doing that for as long as you like. Under FAA certification regulations anything less than
12,500 lbs falls within the category of "
Light Aircraft".
Reaper maximum takeoff weight:
10,494 lbReaper alone puts the wondrous Altius-M to shame. 

But those two
now aging US drone families have just a small and temporary technical and performance edge over the new you-beaut Russian HALE super-duper drones! ... which are just months away! ... ...
no, really! ...
Dude, that's one whole lot of
nuthin' burger.
