Why the Kiev class was built around the wrong aircraft

What warship class was the biggest design lemon?

The Kiev class, because it was built around the badly limited Yak-38 Forger and became a cruiser with a flight deck attached.

The Kiev differed from the earlier Moskva helicopter carrier, which performed a clear anti-submarine role. Kiev instead combined a cruiser with a flight deck to support a vertical-takeoff aircraft that imposed severe limits on the whole concept. The problem is not eccentric appearance alone but designing a large ship around an inadequate air system. The class is the leading candidate here for a modern warship design that failed as a system.
