Trump has raised security concerns about handing over highly secretive Patriot blueprints in their entirety to Ukraine. Ukraine could benefit from a Lockheed Martin project to build a new, lower-cost Patriot interceptor , the PAC-3 Adapted Capability Effector (ACE) missile , Reuters has reported. Lockheed Martin suggested an accelerated timeline for Patriot PAC-3 ACE in an announcement on 20 July, emphasising that the use of the same launchers and software would speed up development. The interceptors would cost less than half of a normal Patriot missile, it claimed. Over Wednesday night the Russian regional governor announced Ukrainian drones were attacking Yaroslavl oblast.
