It are the first six Su-30MKA of 28 ordered in 2006, they are produced by Irkut, so from the Su-30MKI branch. Looks like they aren't breaking their delivery promises, bravo to them. Irkut has been rolling Su-30s off their production line in full tempo for some time now, completely different story than the Yak-130. But I think the first Yaks for Algeria have been finished now and are undergoing testing?
The AF commander refused some MiG-29SMT's because they were second hand surplus aircraft (which was the deal I think), but the point was that they were not overhauled properly and there was talk the air force rather would buy new ones (MiG-29M/MiG-35) then. This kinda screwed up the delivery and financial schedule of course. As far as I know, it is still accepting the two-seaters though, which are produced up to the desired standard. The Flankers are not replacement for this deal, at least not these 28.
Algeria needs to replace a big fleet, choosing a hi-lo mix of Flankers and Fulcrums makes sense.
T-90, well I'm not watching tanks, but it's all part of that 2006 deal, I wouldn't be surprised if it actually takes longer to ramp up or gear up T-90 production than for these higher priced aircraft.
