Naval News – The World’s only operational conventionally powered ballistic missile submarine (SSB) may soon emerge in North Korea. The Romeo-Mod submarine, also known as Sinpo-C, was first revealed on North Korean TV on July 23 2019. It will likely be armed with three Pukguksong-3 missiles which are the hermit kingdom’s best performing. So it will, on paper, pose a serious threat to U.S. and allied targets in the region. But how real is the threat?
