Why a frigate deck is a poor routine base for V/STOL aircraft

Could a V/STOL aircraft operate from an ordinary frigate's helicopter deck?

Emergency use may be possible, but routine operations need a larger deck, and an F-35B also needs reinforcement and heat protection.

Royal Navy experiments with the Harrier included using small ship decks and considering a crane that could recover the aircraft from the air. Such arrangements lacked the landing space of a larger flight deck. A deck on the scale of an Albion-class or landing ship dock is suggested for more practical Harrier use. An F-35 also requires suitable reinforcement and heat treatment. A separate example of an emergency landing on a merchant ship shows that getting an aircraft aboard can create recovery costs without making the vessel a routine aviation base.
