SEOUL, Jan 24 (Reuters) - North Korea’s flurry of new missile tests, including what it calls “hypersonic” https://www.reuters.com/world/asia-pacific/nkorea-tests-hypersonic-missiles-global-race-new-rockets-2022-01-11 weapons, has underscored the importance of the country’s missile engineers and scientists, a group that is high profile within his government but opaque to outsiders.

Analysts say Kim Jong Un appears to be taking steps to institutionalize the missile forces, signalling his likely intent to make them a long-term, operational part of his military plans. https://www.reuters.com/world/asia-pacific/nkorea-warns-it-may-rethink-moratorium-nuclear-missile-tests-2022-01-19 Here's what we know – and what we don’t – about these key personnel.

THE SCIENTISTS

Very little is known about the names and positions of the mid-level and working-level scientists and technicians involved in missile research and development.

Analysts say these individuals appear to have guaranteed job security because of the resources and effort expended to educate and train them, and they are sequestered to special districts so they are neither a defection risk nor a political or social nuisance to the regime.

“Unlike economic cadres or even military commanders, this is a population that is not easily replaced,” said Michael Madden, a North Korea leadership expert at the Washington-based Stimson Center.

Many of them attend Kim Jong Un National Defense University, a training ground for North Korean defense-related science and technology specialists that has reportedly added a college focused on “hypersonic missile technology.”

The scientists and engineers often appear split into competing teams designing similar types of weapons, allowing them to go down multiple routes to see which technology is the most promising, said Ken Gause, director of the International Affairs Group at CNA, a non-profit research and analysis organisation based in Arlington, Virginia.

A 2018 study by the James Martin Center for Nonproliferation Studies (CNS) found North Korean scientists had worked with researchers in other countries to co-write at least 100 published articles that had identifiable significance for dual-use technology, weapons of mass destruction, or other military purposes.

THE OFFICIALS

Kim Jong Un relies on three top people https://www.reuters.com/article/us-northkorea-missiles-trio-exclusive-idUSKBN18L302 to lead the secretive country’s rapidly accelerating missile programme.

They include Ri Pyong Chol, a former top air force general; Kim Jong Sik, a veteran rocket scientist; and Jang Chang Ha, the head of a weapons development and procurement centre.
