The Friedrichshafen FF.33j was a refinement of the FF.33 line, with a two-way radio rather than the 33e's transmitter-only radio. Like most radio-carrying FF.33's, no armament was carried -- protection was expected to be provided by escorting planes.  In May 1917, 30 FF.33j seaplanes were in service.

- An order for 30 was placed in 1918, but it is not certain how many were completed before the armistice.
