Speaking from a maintenance point of view, the harriers are pieces of sh1t sorry to say. It invovles so many man hours in upkeep. Looking at replacing a motor, you have to call the Airframes shop to remove the wing before the Powerline guys come in to remove th motor. That is a pain in the a$$. Check this out, it only takes 1hr 45min to drop and replace a 18 motor get the pilot in the air.
Let me tell you a little history about the harrier and the v-22 in case you all did not know. This concepts were not the United states from the get go. They were copied from Great Britain. That is why we had problems with them when they first brought them into service. The Marine Corp was sticking helo pilots into harriers at first and they were loosing the things left and right until they trained their piltos properly. Secondly we had a problem with the take off until that was resolved. Speaking of the V-22. This concept was first adopted by Britain, but in order for the congress not to seek permission to copy the concept, they asked the miltary contractors to design something which was totally against aerodynamics, so that in adverse weather conditions, them things were blown by cross winds like it was cool.
The F/A 18 will always be the smartest thing the Marine Corp ever spent its money on. It is good for Air to Air and Ait to ground. Should the Corp, get the E/F's probably not, but we cannot always take pass downs from the Navy- in any case like somebody said above let the navy give us the C and D's we will be glad to upgrade it avionics and use it to kill Challie. The Corp does not need anything fast and furious.
To the A-10's. Those things can be the best air to group machines. You are basically flying a gun. That would be a smart pick for the Marine Corp, because this STOVL concept is not really the best. The engines on this things FOD like it is cool and also there are too many moving parts that assist in flight. In the case of a system failure, the pilot might not have too many options. Too many moving parts have a higher possibility of system failure. On other thing, the Marine Corp needs an aircraft with 2 engines and not one, so that incase there is a flame-out or what not we can still get the bird home.
