Having served in the Navy I can tell you that this is a very tough school to complete. The drop out rate is very high, above 70%, but if your son is disciplined and focused the rewards and bonuses can be very good not to mention the long term job prospects with nuclear power plants. The "Nuke" program is a minimum six year commitment not four as stated in previous post. The first two years are school heavy in math, electronics,physics,operating systems,etc, this was not my specific rating but knew people who served in the nuclear ratings.Hope this helped a bit
