 * ''"Apparently, the Americans have not forgotten the April 2014 incident when one Su-24 practically 'blacked out' all of the electronics on board the newest American destroyer Donald Cook," the source said.
 * According to documentary film Crimea-the road to the Motherland (Крым. Путь на Родину), Russia deployed in Crimea modern coast defense missile system Bastion, and made sure it is visible from space. They than illuminated Tomahawk-equipped Donald Cook, with Crimea in the range, with "Bastion" radar. At that point, Donald Cook turned back.
