Hello; Russia needs such a large helicopter to supply parts to remote nuclear silos. There is no asphalt in Siberia, Russia, and trucks cannot move because of heavy snow in winter. Russian helis are way better than US expensive CRAP due to over priced, but offering the same service as Russian. Half of the Super Stalion's price is world's largest, weight lifting Russian heli. Shame on US products. Another interesting thing is that many do not know that MI26 was modernized. Now he can dive up to 100 meters under water, and also include turbo-hyper in the stratosphere! If your going to include the MI-10 (only has 8 ton carrying load) which is no longer flying then you should include the MIL V-12. which was designed to carry 25 tons, ended up carrying 40 tons. The Mi-26 is only 20 tons. At 5.00 is an A model, not a B. CH-54A. The B model has a different rotor head/swash plate, landing gear, bigger horizontal stabilizer. Those are the visible differences. One questions? Can the power of helicopters be combined? And after that can these lift up the RMS TITANIC from the atlantic ocean?
