for Dassault Mirage III upgrade with over sixty-five sold to Pakistan for PAF Mirage-IIIs upgrade under Project ROSE, including the complete radar sets at the beginning of the program and kits for local assemblies in the latter stage of the program. Grifo-M5: As a daytime fighter version of Mirage III, Dassault Mirage 5 lacks radar and the avionics rack behind the cockpit is relocated into the nose, with the space left behind is filled with a 470 liter fuel tank, resulting in Mirage 5 has greater range and slimmer nose than Mirage III. Grifo-M5 is designed to be fitted into the smaller nose of Mirage 5 for its upgrade market, but despite the smaller size of Grifo-M5, the avionics rack must be relocated somewhere else on the airframe of Mirage 5 to clear the room for Grifo-M5 installation, thus requiring more extensive work in comparison to earlier Grifo radars that only require simple installation/replacement, and this is a job for aircraft manufacturing and maintenance firms. As a radar house, Leonardo S.p.A. did not have the capability for airframe upgrade at the time, compounded with aging airframe of Mirage 5, despite successful flight tests, no known sale has been achieved. Grifo-S Grifo-S is a series of large radars the Grifo family designed for medium and heavy fighters, but most of them failed to enter series production. As with earlier Grifo series in the family, models in this series also share the same components except the antenna, and due to the different sizes of antenna, the maximum range of each model also various somewhat. In comparison to earlier series, Grifo-S has the additional compatibility with semi-active radar homing air-to-air missiles, and SAR mode. Grifo-S1: designed for Dassault Mirage F1 & MiG-23, no known sales achieved. Grifo-S5: As an upgrade of earlier Mirage 5, Mirage 50 has a more powerful engine and longer nose to house the X-band Agave radar. Grifo-S5 is designed to be fitted into the more spacious nose of Mirage 50 for its upgrade market. As with earlier Grifo-M5, more extensive work is needed to relocate the avionics rack to clear the space for Grifo-S5 installation on Mirage 50, and for the same reason, no known sales were achieved despite successful flight tests as Venezuela, one of the only two foreign users of Mirage 50, retired its aging Mirage 50 fleet, and Chile, selected Israeli EL/M-2032 for upgrade.
