The Navy’s Plan B is still taking shape. But its outlines are coming into view, thanks in large part to recent comments from its top officer. It involves fewer F-35s (the Navy’ll still buy some) and more copies of the older Boeing F/A-18E/F Super Hornet carrier-based fighter, which the Lockheed Martin-built F-35 was originally meant to replace. In the unlikely event the F-35C — the naval version of the radar-evading plane — gets canceled, the Super Hornet could be upgraded past its current shelf life. The twin-engine F/A-18E/F is already getting new weapons. Extra fuel tanks and some stealth treatments could be added as well.
