The Ramses II tank is a heavily modernized T-55 main battle tank designed for and used by the Egyptian Armed Forces. A single T-54 was sent to the United States for upgrading. A primary prototype was sent to Egypt where extensive trials were completed in late 1987. The tank finally entered production in 2004–2005. A total of 425 units have been produced. The tank was originally called the T-54E ("E" stands for "Egyptian").
