US President Donald Trump has backed away from plans to allow Ukraine to produce Patriot missiles under license, raising new doubts over Kyiv’s ability to strengthen its ballistic missile defenses before Russia’s expected winter campaign, The Telegraph reported.According to the magazine on Tuesday, the dispute centers on the Patriot’s highly sensitive Ka-band Active Radar Seeker, a small radar component that guides the interceptor toward incoming ballistic and cruise missiles during the final stage of flight.JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official.Trump initially said in July that the US would license Patriot production to Ukraine, but later reversed course, citing concerns over transferring sensitive military technology.“It’s a hard thing to give away that kind of technology ... People that you give that technology, they can some day turn on you,” Trump said.Why the Patriot radar is so importantThe Ka-band radar seeker, produced by Boeing in Huntsville, Alabama, acts as the Patriot interceptor’s final guidance system.The component is housed inside the missile’s nose, which is around 10 inches in diameter, with the radar itself estimated to be about eight inches wide.When the interceptor approaches its target, the radar allows it to locate and track fast-moving ballistic or cruise missiles and guide the Patriot into a direct collision.The technology is tightly controlled by Washington. Although around 20 countries operate Patriot systems, Germany and Japan are the only countries currently licensed to manufacture their own missiles, according to The Telegraph.
