Following the successfull flights of the J1, the IDFLIEG ordered a second experimental type in January 1916. This time IDFLIEG added its specifications for an all-metal fighter aircraft with better climb performances than the J1. This initial order was placed for a total of six aircraft. They were built under construction no. E250/16 to E255/16. The prototype E250/16 performed its first flight six month after the inital order on July, 11th 1916. Again this flight was performed at Doeberitz by Lt. Mallinkrodt.

The basic demands for a better climb performance were fullfilled with the J2 design. Also the payload demands were offered. But the required flighttime of 5 hours per flight as well as the request for better maneuvering could not be offered by the prototype. The following five aircraft therefore were equipped with the stronger Mercedes DIII engine. They also got slightly larger wing than the prototype. But now, the payload had to be reduced by 100kg due to the heavier engine. Finally also the J2 did not match the demands of IDFLIEG and the design was dropped.

During the flight tests of one of the J2s, Max Schade was killed on September, 23rd 1916. He crashed with E251/16 when he lost control during slow flight trials at an altitude of 300m.
