that platform is past its prime, and incapable of service against an enemy that can actually fight back. very low survivability, despite what the discovery channel tells you. the gun fires rounds made of depleted uranium, which is not only seriously out-of-step with the times, but may also face production shortages with little or no new nuclear weapons being built and an unfavorable view on nuclear power.
You can't replicate the A-10's low and slow capabilities on any other platform. They are essential for an Afghanistan-like environment and even in western Europe, where it would've engaged Soviet Tanks, it had a better chance against ZSU-23s. It could be flown very low "in the mud", pop up, fire at a target with the gun or launch a Maverick, then make quicker retreating 180 degree turns than an F-16 therefore minimizing ZSU-23 engagement time. Versus SAMs, being low sure helps to prevent enemies having a proper sight picture, as well as having those high bypass turbofans partially shielded by the tail and elevators.
not just the f-4, but the f-111 was 100x the lame duck. the navy pretty much said "if you're going to force these onto carriers, we'll push them off"
But it was an amazing at low level penetration and interdiction as it was intended. Blame Macnamara for being such a dipshit.
the b-1 was another expensive lame duck, and president carter was right to cancel it (and its bespoke nuclear payload). it was incapable of performing its mission. it was rendered obsolete in 1960 when francis gary powers' u-2 was shot down over the ussr, 14 years before the b-1's first flight. the entire concept of a higher, faster bomber was, and always will be, dead. it was revived as a low-level sub-sonic conventional bomber as part of president reagan's spendathon while the b-2 was on the drawing board.
As a low level penetration bomber loaded up with SRAMs, it scared the hell out of the Soviets. It also can carry over twice the payload of a B-52.
the f-14 (yet another drastically overpriced swing-wing) was adequate at its time, in its role as fleet defense fighter. however, it completely sucked at anything else, and the f/a-18 is capable of performing all of those things and more. a single, less expensive and more flexible platform to maintain, support and house aboard a ship - it's a no-brainer.
The F-14 is still the only true long range interceptor the US military has ever had, and the Pheonix the only long range AAM. F/A-18E has a smaller fuel load and of course the F-14 had a huge speed advantage which matters when you're trying to impart energy into a missile to maximize it's range. It's other main problem was the TF-30 engine which was underpowered and tended to suffer from compressor stalls. Admittedly it was an expensive plane, but for the job it was a great aircraft and it's planform podded engine design was as revolutionary as the variable geometry wings. The Tomcat 21 development would've made the design much more capable in all aspects, including 27,000 lb thrust engines, expanded fuel capacity and all the A2G capabilities the F/A-18E has today, but with greater range and speed. F-14s also had larger, higher ranged radars thanks to a larger radome. The Tomcat 21 would have had a much more capable AESA probably in the same class as the F-22's.
there is no way you can convince me the f-4 can be comparable in any way to the f/a-18
So much of a fighter's flight and maneuver performance can be based on it's engines and thrust to weight ratio. The F-16 is the supreme example of a high thrust to weight ratio that provides the engine power to push the plane through constant 9G maneuvering, while still overcoming drag produced by the blended LERXed tailed delta wing design that maximizes vortex lift and deflection lift at medium alpha. It's an energy dogfighter to the extreme :biggrin:
The "Super Phantom" demonstrator flown by Israeli Aircraft Industries with PW1120's gave it a 1:1 air combat load thrust to weight ratio. I would still take the Hornet over the Phantom, but the Super Phantom was close enough in performance to make McDonnell Douglas against selling it or upgrades at the possible cost of Hornet purchases.
There were quite a few Phantom developments, including a serious F-4X reconaissance variant with Mach 3.0 dash capability thanks to water injection.
