Engineering technology unlocks radar, nuclear weapons, jet and rocket engines, and improves research speed, encryption, decryption, and rocket artillery attack.

Engineering technology is separate from industrial technology, meaning the player must hire an engineering design company such as the USA's General Electric (+15%) in order to get research bonuses for engineering technology research. A nation may also be offered political decisions, for example "Give refuge to German scientists (+5%)" or "Give refuge to Italian scientists (+5%)", that give a bonus to engineering technology research for a Political Power (PP) cost.
