This protrusion under the vertical stabiliser doesn't look like an air intake?

This is present now on Thunder Block 3 too.

Either missile approach warning system or radar warning receiver. I go with the first one MAW.

The one on Block 3 Thunder is an intake to cool the avionics.

This however, doesn’t seem to have a mouth so this could be part if MAWS or RWR or even a differently designed cooling intake.
