Russia can make this claim because it’s already been used on the U.S. Navy on Barack Obama’s watch… and nothing was done about it.
That’s right. The USS Donald Cook, while performing duties in the Black Sea, was shut off like a television set by a Sukhoi-24.

RUSSIA has claimed it can disable the entire US Navy using the latest “electronic warfare” technology – as the world braces for conflict.
A recently released Russian news report claims Vladimir Putin’s armed forces can use electronic signal jamming to render missiles, ships and planes completely useless.
In the report, the newsreader said: “Today, our Russian Electronic Warfare troops can detect and neutralise any target from a ship’s system and a radar, to a satellite.
“You don’t need to have expensive weapons to win – powerful radio-electronic jamming is enough.”
The video clip even quotes top US General Frank Gorenc, who said: “Russian electronic weapons completely paralyse the functioning of American electronic equipment installed on missiles, aircraft and ships.”
…
The video describes it as an “invisibility cap from the enemy’s radar” as the report shows how the Russians have developed electronic technology to prevent them from seen by US planes.
The electronic warfare can destroy the American equipment installed on missiles, aircraft and ships.
The video clip claims radio-electronic jamming is better than any other “expensive equipment” needed to win.
