F35 A, B & C models
The C variant lands like most navy jets by snagging a wire with a tailhook at over 100 knots, when these landings go wrong 'nobody died' is a good result.
Landing (Automated or not) in anything other than a flat calm become progessively more dangerous as the seas worsen to the point of scrubbing flight operations entirely due to deck pitching*. The old Harrier showed it could land in far worse conditions by arriving alongside the centre of the ship and side stepping onto the deck slowly.
The F35 has three concurrent models in production, 'A' is land based, non carrier & non VTOL, 'B' is VTOL, 'C' is a non VTOL and has a larger wing area.
the A & C models are very similar in design & capabilities while the B only looks the same but has a massive lift fan & gearbox behind the pilot taking up space that on the other models would be fuel & internal weapon space.
The 'B' variant exists because the USMC (and many other users) really like the Harriers ability to operate from anywhere their helicopters can.
On a side note the Japanese lost an F35A in 2019 most of which is still missing after crashing into the sea north of Japan.
*Aircraft arriving at the stern while it's moving up or down at speed risk either missing the wires and collecting the up swinging bow or hitting far too hard and being wrecked.
