https://www.theengineer.co.uk/issues/february-2013-online/this-month-in-1955-the-steam-catapult/

"Prior to the use of steam catapults, aircraft had been propelled into the air
using a hydro-pneumatic system which used steel wire ropes to drag a small
trolley along the flight deck, with the aircraft towed along behind. This was
fine for the relatively small and lightweight aircraft carried by naval vessels
in World War II, but with the advent of jet engines, carrier-borne aircraft
became heavier and needed to be launched at greater speed. For a while, naval
architects just increased the power of the hydrodynamic system, but the heavier

catapults were growing too large to be installed even on the biggest ships.
