10 ~12 years.
The Navy's ship-building programs are taking a huge amount of bucks to produce things like the Littoral Combat Ships (too small, too undermanned, armed with Bofors and a 5 inch pop gun), $5+ billion dollar stealth (Zumwalt-class) destroyers, $5~$7 billion dollar Virginia-class submarines, and my personal favorite, the $16~$40 billion dollar Ford-class aircraft carrier. (Arleigh Burke-class destroyers cost at least $1.8 billion dollars; Nimitz-class aircraft carriers averaged around $4.5 billion dollars each prior to the $6.6 billion dollar USS G. H. W. Bush.)
The Air Force has also lent a hand spending $$$$$. Some examples include: the $243 million dollar F-35, $418 million dollar F-22s, $100+ million dollar Ospreys, $100 million dollar F/A-18 Super Hornets and the $$2.1 billion dollar B-2.
The Army wants to replace all it's Hummers with $200+ grand Ground Combat Vehicles, new networks, new camouflage uniforms, and my personal favorite, $89 grand precision 155 rounds.
I think sequestration is stupid, but I also think it may be a chance to stop some of this war and war preparation nonsense.
Taking schools away from kids to keep weapons production going is also stupid, IMO.
