My comment:
(a) Please read the first 2 1/2 paragraphs only.
(b) The report says Tomahawk Block IV (other blocks are similar in this aspect) has "a speed of 600-900 kilometers an hour." Everybody knows Tomahawk is subsonic.
* speed of sound en.wikipedia.org/wiki/Speed_of_sound
("In dry air at 20 °C, the speed of sound is 343.59 metres per second (1,127 ft/s). This is 1,236 kilometres per hour (768 mph)")
