Allison J35 Turbojet

Developed by General Electric in parallel with the Whittle-based J33, the J35 was the U.S. Air Forces first axial-flow compressor turbojet.  The J35 first flew in the XP-84 in 1946.

Like the J33, responsibility for developing the J35 was transferred to Allison in 1946.  More than 14,000 had been built by the time production ended in 1955.
