The K9 Thunder self-propelled howitzer, which Estonia wants to add to its inventory, can be postponed to a later date due to the rapid spread of the coronavirus. Estonia, which previously bought 12 howitzers from the Republic of Korea, wanted to supply six additional platforms. Estonian Defence Minister Jury Luik, who is expected to visit Seoul last month, has cancelled his trip. Many speculate that the abrupt cancellation was related to COVID-19. “I don't believe the virus situation would affect Estonia's plan to buy them, but related procedures could be postponed,” a source said.
