Steamrunner class

## SPACECRAFT CLASS

The ***Steamrunner*-class** was a type of spacecraft developed by Starfleet in the mid 24th century.

## History

Development of the *Steamrunner*-class was authorized under the Perimeter Defense Directive in the 2360s. Starfleet Command instructed Advanced Starship Design Bureau engineers at the Laikan Starfleet Shipyards to design a vessel intended for patrolling the borders of the Federation. Responsibilities of the new design were also to include intelligence gathering at the outskirts of Starfleet's influence.

## Technical specifications

### Physical description

The *Steamrunner*-class had a length of 356 meters, a beam of 263 meters and a total height of 59.5 meters, although the height of the primary hull itself was only 45.5 meters.

### Deck plan

### Command systems

#### Bridge

The bridge layout followed standard Starfleet design principles. Four entries were located in the forward corners, two to port and two to starboard. The foremost on both sides were turbolifts. The second door to starboard led to the commanding officer's ready room. This was mirrored portside with the entry to the Deck 1 corridor, which led to the executive conference room and the head.

#### Ready room

The *Steamrunner*-class included a ready room off the bridge to serve as an office for the ship's commanding officer. Along the viewports was a long couch with a basic consumables replicator integrated into the starboard wall. A entry from the bridge was located starboard, while a door to the executive conference room was port. Between the doorways was a desk for the CO.

#### Executive conference room

Located aft of the bridge and port of the ready room on Deck 1, the executive conference room provided a space where the commanding officer of a *Steamrunner* starship could consult with their senior officers or visiting dignitaries. Central to the space was a conference table with seven chairs. Facing aft were three viewports and opposite these was a interactive display. The starboard doorway led to the CO's ready room, while a corridor was outside the door to port. A basic consumables replicator was mounted just inside this port entry.

### Crew support systems

#### Recreational facilities

Located on the port side of Deck 5, the mess hall aboard *Steamrunner* frigates contained numerous booths, tables, and a bar where crews could relax, socialize, and eat. Four replicators were provided, allowing personnel to order a variety of programmed meals.

## Derivatives

### *Sabrerunner*

A product of the Dominion War, the *Sabrerunner*-class applied the *Steamrunner* layout and armaments to a vessel similar in size to the *Saber*-class.

### *Zephyr*

As the Starfleet Corps of Engineers began a massive refit program in the 2390s, the *Steamrunner*-class was revisited and upgraded. The new *Zephyr*-class applied technological advances from the last twenty years to the *Steamrunner* frame, including tactical elements of the *Akira*-class. The new design was developed alongside, and shared many elements with, the *Oslo*-class, itself a subclass of the *Norway*-class. The nacelles were less-integrated in the *Zephyr's* design compared to the original *Steamrunner*, to make maintenance and replacement of warp coils and other components easier.

### *Appalachia*

Entering service in 2411, the *Appalachia*-class was the 25th century update to the *Steamrunner* design.

## Ships commissioned

It was standard practice to name *Steamrunner*-class vessels after mountain ranges.
