IAI stated that they were willing to be highly flexible with the Nammer's launch customers, being open to giving them great leeway over modifying the design and incorporating their own systems as to their preferences.

While the proven delta canard configuration of the airframe had been retained, testing was focused upon the new avionics installed, which were said by IAI to make for a relatively modern fighter aircraft.

[2][1] Speaking on the Nammer, Moshe Scharf, IAI's director of international military aircraft marketing stated of the reasoning behind the initiative: "Upgrading the existing Kfir platform will not be as cheap as building a new airframe based on the proven delta canard concept".

Customers were to have been offered a choice of two basic configurations of the type, one based around re-engining the aircraft with a General Electric F404, while the other was to have retained the Mirage's SNECMA Atar engine but integrated either the Elta EL/M-2011 or EL/M-2032 fire-control radar.

[5][3] It is known that in the course of these negotiations, IAI offered a high degree of customisability to prospective operators, essentially allowing for them to make a significant impact upon the Nammer's design.

[2] During 1990, as part of a renewed sales effort, IAI offered to effectively entirely transfer production of the Nammer, along with the onboard systems and software, overseas to customers.

[6] Externally, the design bore a strong resemblance to the C7 model of the Kfir; however, it could be easily distinguished by the presence of a longer nose and the lack of a dorsal airscoop at the base of the leading edge of the tailfin.

[4] According to IAI, the Nammer was to be equipped with an advanced weapon management system that was directly integrated with a multimode pulse-Doppler radar, while its electronic warfare suite included features originally designed for the cancelled Lavi would also have been potentially used.
