Hwasong-11B

The Hwasong-11B (), also known as KN-24 under the United States naming convention, is a North Korean single-stage, solid-fueled tactical ballistic missile. A missile cloning the American ATACMS, it was first revealed on 10 August 2019 with a test flight. The official designation was confirmed in October 2021, during a military exhibition. The missile is reported to be used by Russian force during Russo-Ukrainian war.

==Description== The Hwasong-11B is a missile that bears similarities to the American ATACMS and South Korean KTSSM, especially in external resemblance, which is similar to ATACMS. It likely fills a similar role of supporting battlefield operations. The missile's aft-mounted aerodynamic fins are fixed rather than foldable like those on the ATACMS, requiring deployment from rectangular launch canisters. It flies in a "variable ballistic trajectory," flattening out at a lower altitude, below around , than traditional SRBMs like the Scud, where the atmosphere is dense enough, so the missile's fins can maintain aerodynamic control over its entire flight and dive toward the target.
