The intent of the Advanced Propulsion with Onboard Power (APOP) system is to increase the available onboard power for the Stryker from 16kW (570A) to 120kW to support future vehicle capabilities such as directed energy, electromagnetic armor, and electronic warfare. The additional power is also used to run electrified automotive auxiliaries on the vehicle such as the main fan and the hydraulic pump more efficiently. Vehicle test results showed that the APOP vehicle had better or equivalent performance to the baseline vehicle when just the electrified automotive auxiliaries are included, but additional future loads still pose a challenge to meeting vehicle performance requirements.
