North Korea is about to celebrate the three-year anniversary of its last intercontinental ballistic missile (ICBM) test, and a state-run publisher has now commemorated the country’s weapons development with a new photo book.

The 63-page book is titled “For Strengthening the National Defense Capability” and tells the official story of how Kim Jong Un built “Juche-type weapons,” meaning new missiles and nukes developed to defend the country and raise pressure on the U.S. 

It could be a useful cheat sheet for what Pyongyang sees as the most important weapons developments of the last decade.
