This would have been a Sea Lightning...
Otherwise it should no more be Sea Lightning than the F-4K was the Sea Phantom. The prefix "Sea" in this context has a long history, indicating the kludging of a land-based design into a naval aircraft with greater or lesser success.
WW - According to the great book of SAR the Navy would have money to start buying a future fighter in 2030 once the F-35B/C fleet is done, and as Super Hs start to reach retirement age. Nobody has set a retirement age for the F-22 as yet but as there are only 140-some combat-capable airframes, that in itself is not a big requirement.
