Built as Kfir C1 (IAF serial 709) and later modified to Kfir C1P. 709 was leased to the USN between Apr'85-May'88. The USN/USMC leased 25 Kfirs between '85 and '89, which were officially designated F-21A. They were modified for use as unarmed adversaries. 12 F-21s were painted in this 3-tone blue-gray "ghost" scheme and were operated by Fighter Squadron (VF) 43 "Challengers" ('AD'), operating out of Oceana. In 1988 they were returned and replaced by the F-16N. The other 13 were assigned to VMFAT-401 at MCAS Yuma (AZ), these were replaced by the F-5E in '89. 709 is last seen stored at Tel Aviv.
