VOICE-OVER:
A modified Navajo
missile—test article for an XK-PLUTO payload—dives away from a
carrier plane. Unlike the real thing, this one carries no hydrogen
bombs, no direct-cycle fission ramjet to bring retaliatory
destruction to the enemy. Traveling at Mach 3, the XK-PLUTO will
overfly enemy territory, dropping megaton-range bombs until, its
payload exhausted, it seeks out and circles a final target. Once
over the target it will eject its reactor core and rain molten
plutonium on the heads of the enemy. XK-PLUTO is a total weapon:
every aspect of its design, from the shock wave it creates as it
hurtles along at treetop height to the structure of its atomic
reactor, is designed to inflict damage.
