North Korea’s Kim Ju Ae: The “Successor-Designate” on the Rise
Kim Jong Un’s young daughter, Kim Ju Ae, has been thrust into the state spotlight since late 2022, marking a historic shift in the North’s royal succession narrative.
A Rapid Ascent
Since her first public appearance in November 2022 at an intercontinental ballistic missile test, Kim Ju Ae—identified by external sources as approximately 13 years old—has been increasingly featured in state media. South Korea’s National Intelligence Service (NIS) now assesses that she has officially progressed from "successor training" to a "successor-designate stage," a designation shared with lawmakers during a closed-door briefing in early 2026.
Key Appearances Fueling the Assessment
The NIS bases its conclusion on a series of high-profile public engagements alongside her father:
- Weapons Demonstrations: She accompanied Kim Jong Un during a live-fire test of multiple rocket launch systems and observed the launch of nuclear-capable cruise missiles from a naval destroyer.
- Factory Inspections: At a light munitions factory, both she and her father tested newly produced pistols. The Korean Central News Agency (KCNA) reported Kim Jong Un rated the new pistol as "excellent."
- Military Parades: She has regularly attended major military parades, including one concluding the ruling Workers' Party congress.
- Diplomatic Trip: In September 2025, she traveled by train to Beijing for a summit with Chinese leader Xi Jinping, attending a military parade commemorating the end of World War II.
- Mausoleum Visit: On January 1, 2026, she visited the Kumsusan Palace of the Sun alongside her parents—a site housing the embalmed bodies of Kim Il Sung and Kim Jong Il. This family outing is considered a powerful symbolic endorsement.
"Acting Missile Director" and Other Titles
While North Korean state media has not officially released her name, referring to her only as Kim’s "most beloved" or "respected" child, she has reportedly been given the symbolic title of "acting missile director" in some reports. Analysts caution this is likely for public presentation rather than an indication of operational authority.
Context and Expert Skepticism
Despite the NIS’s shift in assessment, several analysts and officials urge caution:
- Hong Min (Korea Institute for National Unification) noted that Kim Jong Un’s solo military appearances during his own grooming phase contrast with Kim Ju Ae’s heavy chaperoning, arguing that tank appearances alone are insufficient proof of succession.
- A South Korean Unification Ministry spokesperson stated it is "premature" to conclude she is a successor, citing her age and lack of an official position.
- Party Membership Hurdle: Kim Ju Ae cannot join the Workers’ Party until age 18—a prerequisite for holding official power. Kim Jong Un himself was named heir at age 26 in 2010.
- Rule by Male Leaders: North Korea has been ruled exclusively by male members of the Kim family since 1948. Some experts argue that naming a young female successor so early could undermine her father’s current authority.
"The public appearances contrast with Kim Jong Un's solo military appearances during his own grooming phase—making the tank appearances alone insufficient to confirm her as heir."

Kim Jong Un Remains in Command
While grooming his daughter, Kim Jong Un continues to oversee military and policy developments. During the same period:
- He has observed multiple weapons tests, including ballistic missiles and cruise missiles capable of delivering nuclear warheads.
- He stated a drill involving large-calibre rocket launchers was intended to expose enemies within 420 km to the "destructive power of tactical nuclear weapon."
- The NIS reported he is developing a large submarine capable of carrying up to 10 submarine-launched ballistic missiles.
- At the first Workers’ Party congress in five years, he reaffirmed plans to accelerate the nuclear arsenal and maintained a hard-line stance toward South Korea while signaling openness for dialogue with the U.S.—contingent on Washington abandoning demands for denuclearization as a precondition.
The Kim Yo Jong Factor
The NIS has also assessed that Kim Jong Un’s sister, Kim Yo Jong—recently confirmed as general affairs director of the party’s central committee—does not hold independent power, further suggesting that Kim Ju Ae is the sole intended successor.
Regional Tensions
These internal developments unfold amid ongoing regional security dynamics:
- Weapons tests often coincide with U.S.-South Korean joint military exercises, which North Korea condemns as provocations.
- South Korea’s national security council characterized the ballistic missile launches as a violation of U.N. Security Council resolutions.
- U.S. President Donald Trump has expressed interest in meeting Kim Jong Un, while Kim has stated that expanding a "self-defensive nuclear deterrent" is essential to North Korea’s security.
