Stealth won't help the crews attacking the Russia defense, it will be overwhelming force by the US low level at the fringe of the radar coverage. We know we can't take them on high altitude so you wouldn't see it happen. There is a very good plan and probably would even up the score pretty fast but we would lose a lot of aircraft. Drones and cruise missile would probably be the weapons of choice to cut a path. The S-400 is named 400 because it has a range of 400 miles or kilometers. They just make the tubes larger for added fuel load. I think the grand strategy is to let Russia dry up on the vine rather than hit the beaches. Actually I don't think there is a real good chance we would ever go to war with Russia. Now having them join up with another country like Iran and or China is a real possibility. They only have a little over 140 million people so they are numerically already at a disadvantage. Their homeland defense is all mobile, even their aircraft are designed to land on non cement runways because they know the first thing to go is the airfields so they don't invest heavily in fancy large airfields. All their hardware is spread out all over their territory. We have very little left here in the USA after the thieves in congress closed all our bases. I guess in a big war we would have to bunk the troops in our homes like the British did in WWII. They all got rich in real estate sales. Just think, Fort Ord was 90 years old and the largest Infantry training center in the US. Fort Wolters is closed, all the air force bases in the south are gone. I always said for us to win a war we would have to arrest most of our own government and imprison them, these slugs we have today don't have what it takes to win anything. Oh and I have no idea how many misfires they have, but consider they don't waste a lot of money on live fire like we do. When I was in Nike Hercules we had live fire once a year at white sands, of course that was a half a century ago ;0) Oh and when a Herc gets the spark that bastard is down range damned quick, it is so fast on ignition even if it failed it would be a mile or two from the base. It used solid ether motors (4). Only 90 miles but then it was a defense weapon built by Bell Telephone using the latest tube technology and precision machine work to build each guidance computer for each missile, the computers were actually made of metal gears and electro relays mounted in a large aluminum suitcase, easily removed for replacement. Civil Service in Fort Worth took care of any major repairs for our battery and Battalion. The missiles were guided to target by radar that received the input from those computers , they were not a part of the missile itself. I often wonder why they broke up Ma Bell who was a hell of a good defense company. Yet they can't break up something like google or facebook.
