Fast Attack – Episode #2 – Harpoons and Fast Ships
In the second part of my new series focusing on the submarine simulation, Fast Attack High Tech Warfare I play the second mission of the campaign. In it I captain the USS Pittsburgh and attempt to stop Iran from using a fast Guided Missile Frigate and a Missile Boat to blockade the Persian Gulf and the worlds oil supplies.
