An impulse engine (a colloquialization of internally metered pulse drive) was a type of propulsion system technology used for sublight speeds. This technology was used by United Earth, and later the Federation, beginning around the 21st or 22nd centuries. (TOS novel: Final Frontier; ENT novelization: Broken Bow)

The components of the Vorl-tak could be used to construct an impulse engine. (EV - Cloak and Dagger comic: ^{[citation needed]})
