-F model Super Hornet is the replacement.

From what I've read, the Super Hornet doesn't have nearly the range or the
payload of a Tomcat.
True?

Yes, the result of a drag penalty of the new wing and underwing stores.

Three missions from one basic airframe.
F-18E single seat fighter/bomber replaces the F-18C "Hornet"
F-18F two seat fighter/bomber replaces the F-14D "Tom Cat"
and another version, the EF-18G "Growler", replaces the Grumman EA-6B
"Prowler" ECM aircraft.
