If you're referring to the F35, I encourage you to look at the evidence about it. LazerPig [1] does a great job in presenting some of the hair brained ideas of reformers [2]. I used to be firmly in the reformist camp until I actually examined the evidence. The A-10C for example, has one of the highest rates of friendly fire, affecting both US [3] and British [4] servicemen. Using binoculars is not a great way of navigating an aircraft.
I'd also ask you to consider: Is it better to make an affordable aircraft, if it means the pilots flying it are more likely to die?
There's more than enough avenues which can be done to reign in Military overspending. No one is denying that the Military overspends on many things. It's a serious problem. Generally though, targeting the machines keeping people from crashing into the ground is not the one to aim at.

Edit: I think this comment sounded a bit rude the first way I worded it. Hopefully it doesn't now. ¯\_(ツ)_/¯
