The lyrics are about the Intercontinental Ballistic Missile called Titan II.
lyrics
From the depths of the earth
A titan shall rise
Free from it's prison it takes to the skys
back to the earth it shall return
Nations shall tremble and cities shall burn
Emerging from the depths
Satan's power reviled
Rejoicing in your death
Your fate is sealed
Science and Technology
Discovering new ways to kill
Religion and Philosophy
To justify the blood we spill
There are some shots you cannot retake
There are mistakes you cannot unmake
Damocles' sword dividing us all
Millions shall perish when the titan falls
