She was designed by Fredrik Henrik af Chapman, built at Djurgårdsvarvet in Stockholm in the summer of 1778, and launched the same year.

Amphion, named after Zeus' son and culture patron in Greek mythology, served as a royal yacht and headquarters ship.

The ship was essentially a modified turuma, a type of shallow-draught frigate that served in the Swedish archipelago fleet.

Amphion's figurehead and stern castle with the royal command room were spared, and can be seen at the Maritime Museum in Stockholm.
