The Sabra (Hebrew: סברה, 'prickly pear') is an extensively upgraded M60 Patton tank developed by Israel Military Industries.[unreliable source?] Mk II version of this upgrade package was used in one of Turkish Army's modernization programs. The Sabra is known as the M60T in Turkish service. The Sabra was initially developed as a further evolution of the Magach 7C. The ballistic profile of the appliqué armor was improved and it incorporated the MG253 120 mm gun developed by IMI. The upgrade package was first offered to Turkey as an option for its tank modernization program and later offered for general export. The Turkish government selected the Sabra Mk II (a further modified version of the Sabra) for its upgrade program, which was intended as a stopgap measure. A contract estimated to be worth $688 million USD was signed on March 29, 2002. The first Sabra Mk II was delivered for Turkish trials in 2005 and passed qualifications in May, 2006. 170 were upgraded between 2007 and April, 2009. The upgrades were undertaken by the Turkish Army's 2nd Main Maintenance Center Command, with upgrade kits supplied by IMI. (Source: Wikipedia.org, CC BY-SA)
