The Schützenpanzer Lang HS.30 (also Schützenpanzer 12-3) was a German infantry fighting vehicle developed during the 1950s. It was a Swiss Hispano-Suiza design, with a Rolls-Royce engine. After some early mechanical problems only some 2000 were built of the 10,000 planned. It was armed with a 20 mm cannon which was an unusually powerful weapon for an armoured personnel carrier of the period but, on the other hand, it had many flaws and drawbacks. Its construction was followed by a great political scandal in West Germany in the 1960s. 2176 SPz 12-3 and variants were built until 1962, for which the German government paid 517 million DM, or about 238,000 DM per vehicle. The SPz 12-3 was first deployed in 1958 and was replaced by the Marder infantry fighting vehicle from 1971.
