the tank's mobility through the adoption of a new engine and gearbox, as well as to the tank's firepower, with the development of a new kinetic energy penetrator and the introduction of a far more complex and accurate fire control system for the tank's gunner, amongst other things. The AMX-30EM1 was termed a "reconstruction" and only saw improvements to the tank's mobility by adopting a new transmission and renovating much of the vehicle's worn out systems, such as the brakes, indicators and controls. These rebuilt AMX-30s were soon replaced by M60 Patton tanks procured from the United States in the early 1990s, while its fleet of AMX-30EM2s was later replaced by the B1 Centauro anti-tank vehicle. In 1972, France was able to gain a contract with Saudi Arabia over the purchase of 190 AMX-30S', designed for the desert environment of the Middle Eastern nation. Named the Palmier Contract, Saudi Arabia's tanks were delivered between 1973 and 1979, while 59 AMX-30Ds were exported between 1975 and 1979, 12 AMX-30Ps between 1977 and 1979, and finally 51 self-propelled howitzers, delivered between 1979 and 1980. Between 1979 and 1981, Saudi Arabia also received 52 AMX-30SAs and later 50 AMX-30C1 Shanine-2s delivered in two batches, between 1980 and 1989. By the 21st century, 50% of Saudi Arabia's AMX-30 fleet were in storage, given that the AMX-30 lacked the capabilities to deal with more modern threats, such as against Iraqi T-62s and T-72s, and Israeli Merkava tanks. These were largely displaced by an order for 315 M1A2 Abrams tanks in 1989, and the acquisition of 450 M60A3 Patton tanks. Although Saudi Arabia planned to procure more M1 tanks, it was unable to do so for financial reasons and the AMX-30 has still not been retired. Venezuela originally placed an order for 142 tanks in 1972, although this was later reduced to 82 and four AMX-30Ds. In the mid-1980s, Venezuela adopted a modernization plan for its deprecated AMX-30s, opting to replace the original engine with a new Continental AVDS-1790-5A diesel engine, producing and exchanging the existing transmission with an Allison CD-850-6A. Venezuelan AMX-30s received new fuel tanks, increasing the tank's road range to , while firepower was improved through the adoption of a modern Lansadot MkI fire control system and Ballistic computer from Elbit Systems. In 1977, France and Qatar signed an agreement which garnered France another 24 AMX-30s sold, which would rise to 54 when
