North Korea is proving its nuclear prowess with land and sea missiles

The advent of mobile land and sea-based missile systems bring several benefits to Pyongyang.

For one, missiles will be harder to detect and target, according to Bruce Klingner, senior research fellow for northeast asia at the Heritage Foundation. That could increase the regime"s risk to its adversaries, namely Washington, Seoul and Tokyo.

By simultaneously launching multiple missiles from the field, North Korean leader Kim Jong-un can reduce the viability of allied preemptive attacks, launch surprise attacks, engage in coercive diplomacy and have a second-strike capability, Klingner said in a recent commentary.

Moreover, "Pyongyang"s success of solid-fuel engine tests and launches means less time is necessary for a launch, thus constraining warning time," he continued.

Land and sea missiles were two of four strategic goals that North Korea adopted following the death of former leader Kim Jong-il in 2011. A dual-use space program and solid-fuel rocket technology were the other two, Lorenzo Mariani, researcher at Istituto Affari Internazionali, an Italian non-profit, wrote in a report last month.
