For instance, the fact that Russia has more bombers than the US is rather interesting. One of the main reasons for this is that Russia has many old bombers still in service that are cheap, instead of spending their money on new, costly projects to create the \"bombers of tomorrow\". Russia\u2019s main bombers are still the Tupolev 95(Introduced in 1956), Tupolev 160 (introduced in 1981) and the Tupolev 22M (introduced in 1972). Even though many of them have been upgraded since they came in service, the cost can not be compared to both the development cost as well as the unit cost of some of the extreme US projects like the Northrop Grumman B-2 Spirit bomber. As an example, the unit cost of a Tupolev 160 is about $40mill while the one of the Northrop Grumman B-2 is over $2 billion each (unit cost USD 737m - total program cost as of 2004 USD 44.75b with only 21 aircraft produced).\n\n \n\nThe same principle applies to fighters, where the US truly flexes its muscles by having not only more but also more expensive jet fighters than Russia has. The most recent US multirole fighter is the Lockheed Martin F-35 Lightning II (first flight 2006) and the Russian is the Sukhoi-35 (2008). While the cost of the F-35 is around $125 mill, the Su-35 only cost $50 mill. So the fact that the USAF has more expensive and at the same time almost the double amount of jets than Russia has, could explain why the United State\u2019s military budget is so comparatively high See the table below for more details on the different concepts behind these air forces.\n\nEarly Warning aircraft, or as many call it \u201cEyes in the sky\u201d are aircraft with the capability to scan the area around itself looking for incoming aircraft, like a mobile radar station. Since permanent radar stations exist on the ground, early warning aircraft are primarily (almost) used with aircraft carriers and amphibious warfare ships. Because the US has 19 aircraft carriers compared to Russia\u2019s only one, and 31 amphibious warfare ships in contrast to Russia\u2019s two there is an obvious reason to why the US's need of AEWACs is much greater than Russia's currently is.\n\nTransports and tankers are used by all nations, but they are obviously not used as much if the country uses a big part of its military force as a defence as if it operates a lot in another country or on another continent. Because the US maintains a world-spanning network of military bases, protects trade routes worldwide and with the operations in Afghanistan and Iraq, they need to transport their troops and supplies great distances, which is why they have such a bigger number of transports and tankers than Russia has.\n\nTrainers are used as can be easily figured to train pilots. There is basically only one reason why the US Air Force has so many more training aeroplanes: the extreme amount of personnel. The Russian air force has approximately 140 000 persons involved at the moment, while the USAF has almost 700 000! This means that the latter has to train a lot more persons and therefore needs a lot more training jets.\n\n
