Sinai-23

     Notes: This is an Egyptian modification of the M113A3 armored personnel carrier.  In this role, the M113 is fitted with a turret mounting twin ZU-23 autocannons and six launchers for Sakr Eye SAMs (an Egyptian improved SA-7 Grail SAM); the launchers may also launch Stinger SAMs.  The vehicle also has a radar set and a fire control computer with one-axis (up-down) stabilization for the guns.  Applique armor

     The Sinai-23’s engine develops 275 horsepower; in addition, the Sinai-23 has a conventional steering yoke and a brake pedal instead of the differential steering and braking system.  This greatly reduces driver fatigue.  The passive IR periscopic sight was replaced with a thermal imager.   An improved neutral steering system was fitted, restoring the pivot steer capability.  Kevlar anti-spalling liners were fitted to increase protection for the occupants.  Finally, the external fuel cells were made standard equipment on the M113A3, also greatly increasing crew survivability.

     The Sinai-23 is not “officially” amphibious; buoyancy cells can be added to the M113A3’s sides and to the trim vane, but swimming a Sinai-23 is even more dangerous than swimming an M113A2-based vehicle.  An appliqué armor kit called SIFV has been devised for the Sinai-23.
