Emergency holographic program

An **emergency holographic program** was a sophisticated computer program designed to project a hologram that could fill a particular function in an emergency. Originally pioneered by Starfleet, such programs eventually saw use among civilians and other state forces.

After the formation of the Khitomer Alliance, Starfleet developers adapted the various emergency holograms to be used on new Allied Fleet Service vessels, such as the *Khitomer*-class.

## Types

### Emergency Command Hologram

The Emergency Command Hologram (ECH) was introduced in the early 2380s for the specific purpose of taking command when the crew was incapacitated or forced to abandon a starship or facility. A number of programs, with various personalities, were developed by the 25th century and an ECH was standard for Starfleet vessels by the time of the Last Federation-Klingon War.

#### Executive Officer Hologram

A similar program the, Executive Officer Hologram (EOH), was developed concurrently with the ECH. It received a trial-run aboard the USS *Ross* beginning in 2381, but was ultimately deemed impractical for fleet-wide use.

### Emergency Engineering Hologram

The Emergency Engineering Hologram (EEH) was designed to assist or replace engineering staff in times of emergency. They were first used aboard Starfleet starships and facilities in the 2380s. A number of programs, with various personalities, were developed by the 25th century and an EEH was standard for Starfleet vessels by the time of the Last Federation-Klingon War.

### Emergency Medical Hologram

The Emergency Medical Hologram (EMH) was a sophisticated holographic program originally designed to assist medical staff in times of emergency. They were first put into use aboard Starfleet starships and facilities in the early 2370s.

The Mark IX EMH program was stolen by the Orion Syndicate and served as the basis for their holographic programs.

### Emergency Security Hologram

The Emergency Security Hologram (ESH) was designed to be activated in an emergency to supplement or replace security personnel. They were first put into use aboard Starfleet starships and facilities in the 2380s. A number of programs, with various personalities, were developed by the 25th century and the holograms were standard for Starfleet vessels by the time of the Last Federation-Klingon War.

### Emergency Tactical Hologram

The Emergency Tactical Hologram (ETH) was designed to serve as a tactical officer in the event of an emergency.
