An accelerated Grumman fighter sequence

What might follow if the Hellcat and Bearcat each arrived a generation earlier?

The proposed next aircraft is the twin-engined F7F Tigercat.

The question advances the Hellcat into the Wildcat's place and the Bearcat into the Hellcat's. It then asks what might occupy the later slot. The suggested answer is the twin-engined Tigercat. The participants briefly check their recollection before settling on F7F. It is an identification within a hypothetical sequence, without a claim that procurement or carrier integration would automatically follow.
