The Julang-1 (Chinese: 巨浪-1; literally: "Huge Wave-1"), also known as the JL-1 and in US nomenclature as the CSS-N-3, is China's first submarine-launched nuclear ballistic missile. According to a 2011 US Department of Defense, the operational status of the JL-1 was "questionable".[1]


Research and development began in 1967 and detailed design in the early 1970s, with a first land launch 30 April 1982 and a sea launch from a Project 629A (Golf) class submarine on 12 October 1982. The general designer of the missile is Huang Weilu (Chinese: 黄纬禄) 1916-2011;[2] academician Chen Deren (Chinese: 陈德仁, 1922 - December 21, 2007) served as deputy chief designer. The missile was assembled at Factory 307 (Nanjing Dawn Group Limited Liability Company [南京晨光集团有限责任公司]).

The JL-1 was deployed on Xia class submarine in 1986. The Type 092 Xia class nuclear submarines have 12 launch tubes.

The JL-1 was initially tested and deployed on the PLAN's modified Golf class SSB. The Golf has since been modified again for further testing of other missiles, such as the JL-2, which has test-launched multiple times with varying levels of success.

The DF-21 appears to be a land-based version of the JL-1.
