These other bombers “proceeded quietly to the east with minimal communications throughout the 18-hour flight”, he explained.

Pentagon chief Pete Hegseth has said that the US had used other methods of deception as well, such as deploying fighters to protect the B-2 bombers that dropped 14 bunker-buster bombs on Iran’s most powerful nuclear sites, according to an Associated Press report.

Caine explained that a US submarine in the vicinity of Iran had “launched more than two dozen Tomahawk land attack cruise missiles against key surface infrastructure targets” at the Isfahan nuclear site, the CNN report added.

Opening with this, the US employed more deception tactics to enable numerous fourth- and fifth-generation aircraft to push out in front of the “strike package at high altitude and high speed, sweeping in front of the package for enemy fighters and surface-to-air missile threats”.
