Replace the nuclear program with a missile program, which only costs $30,000. There are three unlockable work modes, Nuclear Warhead, Chemical Warhead, and Satellite Program.

To unlock nuclear warhead, have nuclear power plant set to enrich uranium. This, like the current nuclear program, will stop invasions. It will also lower relations with China, the Middle East, and Europe.

To unlock chemical warhead, have a chemical plant. This will prevent rebel attacks, as you are able to gas the jungle until the rocks asphyxiate. This lowers relations with the US and USSR.

To unlock satellite program, have an academy of science. Tropico will handle the world's communications. Each month $10,000 is made charging for this communication. Relations with the intellectuals is greatly increased.
