The US military spends more on R & D then most of the world combined for it's military, but is all this money well spent? Many could argue that alot of the current or upcoming war machines are no better and maybe worse than what they are replacing. Let's look at a few: The M1A2 Abrams SEP(10.68 million) vs the M60A3 Patton (1.4 Million) [ame]https://www.youtube.com/watch?v=h_XGIy77lZQ#t=12[/ame] F22 Raptor (150 million)vs F35 Joint Strike Fighter (237 million) http://www.washingtontimes.com/news/2013/mar/6/report-super-fighter-will-get-pilots-shot-down/ Arleigh Burke-class destroyer (1.8 Billion) Vs. Zumwalt-class destroyer (3.45 Billion) http://stevenmcollins.com/WordPress/?p=5314 I for one favor a strong US Military and don't have a problem with alot of Tax dollars spent on R & D IF they are actually designing better war machines....if not....the money should be going somewhere else. IMO. Thoughts?
