North Korea to Expand Nuclear Arsenal

Leader Kim Jong Un approves sweeping weapons modernization and expansion plan

North Korea announced that it will dramatically expand its nuclear arsenal and conventional military forces, with leader Kim Jong Un formally approving an ambitious plan to accelerate weapons production and modernization. The announcement, carried by the state-run Korean Central News Agency (KCNA), frames the move as a necessary response to what Pyongyang describes as “imperialist aggression” from the United States and South Korea.

According to KCNA, Kim authorized an expansion program designed to ensure “absolute nuclear superiority” by the end of the decade. The plan calls for an exponential increase in the production of nuclear warheads, along with the development and deployment of advanced delivery systems. These include intercontinental ballistic missiles (ICBMs) capable of striking the U.S. mainland, as well as submarine-launched ballistic missiles (SLBMs).

Alongside its nuclear program, North Korea is preparing to overhaul its conventional forces. Plans include modernizing the army, navy, and air force with new artillery systems, submarines, and fighter aircraft. Pyongyang also intends to ramp up production of hypersonic missiles and advanced drones, underscoring its focus on emerging technologies in modern warfare.

“Our military’s might is the cornerstone of national sovereignty,” Kim was quoted as saying. “We must not hesitate to invest all resources in defense against imperialist aggression.”

The announcement comes after a flurry of missile tests in August, including a simulated nuclear strike drill that heightened tensions on the Korean Peninsula. The U.S. and South Korea swiftly condemned Pyongyang’s plans, warning that continued weapons development undermines regional stability.

China, however, limited its response to expressions of “regret” without direct criticism, while Russia remained silent. Analysts note that Moscow’s reluctance to rebuke Pyongyang reflects deepening military cooperation between the two countries. Reports over the past two years suggest Russia has shared technical expertise and technology, helping accelerate North Korea’s weapons programs.

Current estimates suggest North Korea possesses between 50 and 70 nuclear warheads, with the Hwasong-15 and Hwasong-17 ICBMs capable of targeting the U.S. mainland. Its SLBM program, including the Pukguksong-3, remains under development.

Diplomatic channels remain strained. Earlier this year, reports surfaced that U.S. President Donald Trump attempted to send a personal letter to Kim Jong Un through North Korea’s delegation at the United Nations. Pyongyang declined to receive it, a move interpreted by observers as a sign of Kim’s strengthened position due to his alliance with Russia and expanding military capabilities.
