Operation Spruance: The Naval Warfare Simulation

Operation Spruance is a sequel to USS John Young, and lets you command a US
destroyer of the Spruance class in the Persian Gulf.

The game has missions where you must defend civilian cargo ships against enemy
aircraft and prevent attacks from both Iranian and Russian naval forces, who
are using both surface ships and submarines.

The Spruance has many of the actual systems available for your use, selectable
from the function keys, e.g. satellite & radar threat screens and
missile/cannon weaponry & defense systems. Its submarine hunter helicopters,
towed arrays and sonar screens are not implemented, nor are the Phalanx anti-
missile cannons in place.
