The Korean People's Army Strategic Rocket Force (KPASRF; Korean: 조선인민군 전략로케트군; Hanja: 朝鮮人民軍 戰略로케트軍), also known as Missile Guidance Bureau (Korean: 미사일지도국; Hanja: 미사일指導局) is a military branch of the Korean People's Army that oversees North Korea's nuclear and conventional strategic missiles. It is mainly armed with surface-to-surface missiles of domestic design as well as older Soviet and Chinese models. The KPA-SRF was established in 1999 when several missile units under KPA Ground Force Artillery Command were re-organized into a single missile force reporting directly to the office of the Supreme Commander of the KPA via the General Staff.
