Editing Katyusha rocket launcher (section)

== Post-war development ==

The success and economy of [[multiple rocket launcher]]s (MRL) have led them to continue to be developed. In the years following WWII, the BM-13 was replaced by the 140&nbsp;mm [[BM-14]] and the BM-31 was replaced by the 240&nbsp;mm [[BM-24]].<ref>{{Cite web|url=https://milinme.wordpress.com/2011/01/08/the-bm-24-12-in-the-idf/|title=The BM-24-12 in the IDF|date=8 January 2011}}</ref> During the [[Cold War]], the Soviet Union fielded several models of Katyusha-like MRL, notably the [[BM-21 Grad]] launchers somewhat inspired by the earlier weapon, and the larger [[BM-27 Uragan]]. Advances in artillery munitions have been applied to some Katyusha-type multiple launch rocket systems, including [[bomblet submunition]]s, remotely deployed [[land mine]]s, and [[chemical warfare|chemical warheads]].

BM-13s were used in the [[Korean War]] by the Chinese [[People's Volunteer Army]] and [[Korean People's Army]] against the [[Republic of Korea Armed Forces|South Korean]] and [[United Nations Command|United Nations forces]].<ref name="Korea">{{cite book|title=Korean War Order of Battle: United States, United Nations, and Communist Ground, Naval, and Air Forces, 1950-1953|first=Gordon L. |last=Rottman|page=198|date=December 2002|publisher=Praeger|isbn=978-0-275-97835-8|url=https://books.google.com/books?id=NpOp2OO1-DAC&pg=PA198}}</ref> Soviet BM-13s were known to have been imported to China before the [[Sino-Soviet split]] and were operational in the [[People's Liberation Army]].
