The Panzerhaubitze 2000 ("tank howitzer 2000"[2]), (German pronunciation: [ˈpant͡sɐhaʊ̯ˌbɪt͡sə t͡svaɪ̯ˈtaʊ̯zn̩t]) abbreviated PzH 2000, is a German 155 mm self-propelled howitzer developed by Krauss-Maffei Wegmann (KMW) and Rheinmetall in the 1980s and 1990s for the German Army. It is capable of a very high rate of fire; in burst mode it can fire three rounds in nine seconds, ten rounds in 56 seconds, and can—depending on barrel heating—fire between 10 and 13 rounds per minute continuously.[3][unreliable source?] The PzH 2000 has automatic support for up to five rounds of Multiple Round Simultaneous Impact (MRSI). Replenishment of shells is automated. Two operators can load 60 shells and propelling charges in less than 12 minutes.
