Apaches are no good without the longbow radar, also pretty sure the berev a50 has decent capabilities, not sure of its purely an AWACS platform or can carry other duties. Russias working an the berev a100 but it'll take time before we see those spreading its wings in Siberia. Have they at least considered the mi 28 havoc?
According to SC, Algeria is rumored to have contracted 2 of these bad larrys lol, A-100E! Hard to believe since the A50 seems to have just finished its initial testing and now there's A-100s? This would be a good choice, but I think they can get as much, if not more out of smaller and more modern aircraft like the Falcons etc. These behemoths also make for larger targets, now that there are a slew of long range missiles dedicated to smacking AWACs' out of the air.
Check out the last page of the Algerian Army thread, I posted pics of their Mi-28N Havoc and man, what a friggin sick animal that thing is. Love the Ka-52s without a doubt, even the Mi-24s the EAF picked up, but the Havocs like you said might be better options than the Apaches because of their Arbalet radar. Russia's version of the Long Bow you're 100% on the money. Only problem is they're so committed to the Apaches, how to they get out of that deal? Not to mention the absolutely ridiculous, slap in the face devastating cost of the upgrade on those things WITHOUT the Long Bow!!
