The Lince was a Spanish development programme for a proposed main battle tank that unfolded during the late 1980s and early 1990s. The intention was to replace the M47 and M48 Patton tanks that the Spanish Army had received under the U.S. Mutual Defense Assistance Act between 1954 and 1975, and to complement the AMX-30E tanks manufactured for the army during the 1970s. Companies from several nations, such as German Krauss-Maffei, Spanish Santa Bárbara, and French GIAT, made bids for the development contract. The main priorities were mobility and firepower, with secondary priority placed on protection; the Lince tank was to have been lighter and faster than its competitors. To achieve a sufficient level of firepower and protection, the Lince was to use Rheinmetall's 120 mm L/44 tank-gun and German composite armour from the Leopard 2A4.
