The UAE has begun production of a greater amount of military equipment, in a bid to reduce foreign dependence and help with national industrialisation. Example of national military development include the Abu Dhabi Shipbuilding company (ADSB), which produces a range of ships and is a prime contractor in the Baynunah Programme, a programme to design, develop and produce corvettes customised for operation in the shallow waters of the Persian Gulf. The UAE is also producing weapons and ammunition through Caracal International, military transport vehicles through Nimr LLC and unmanned aerial vehicles collectively through Emirates Defence Industries Company. The UAE operates the General Dynamics F-16 Fighting Falcon F-16E Block 60 unique variant unofficially called "Desert Falcon", developed by General Dynamics with collaboration of the UAE and specifically for the United Arab Emirates Air Force. The United Arab Emirates Army operates a customized Leclerc tank and is the only other operator of the tank aside from the French Army. The largest defence exhibition and conference in the Middle East, International Defence Exhibition, takes place biennially in Abu Dhabi.
