Sojourner class

## SPACECRAFT CLASS

Class development project patch (Thomas Marrone).

The ***Sojourner*-class** was a type of spacecraft developed by Starfleet in the early 25th century as a refit of the *Odyssey*-class.

## History

Developed in the aftermath of the Second Battle of Earth, the *Sojourner*-subclass was a concerted effort by Starfleet engineers to create a new generation of the *Odyssey*-class, designated Block II. Designed alongside the *Endeavour* and *Yorktown*-classes, the *Sojourner* (Block II/O) was an update of the Block I operations variant and was focused on tactical readiness.

## Technical information

### Physical arrangement

A new design for *Odyssey-*class space-frames, the *Sojourner*-subclass used the same basic arrangement common to most Starfleet capital ships. The vessel was composed of two hull sections: an ovular, domed primary hull and a detachable secondary hull housing the main engines and warp drive. The two hulls could be reversibly separated, affording the stardrive section improved agility.

### Command systems

#### Main bridge

The main bridge of an *Sojourner*-class was little different from an *Odyssey*-class bridge. It covered two decks with a vaulted ceiling on the underside of the inner pressure hull. It had an observation deck by the forward viewport that afforded a panoramic view of space. Chairs for the commanding officer and two bridge officers were in the center with a view of a large viewscreen, and surrounded by crew stations. The bridge turbolifts were on the port side, the captain's ready room was to starboard, and a seven-pad transporter was set into the aft wall. The lower deck was below the observation deck and included additional crew stations.

### Propulsion systems

Standard equipement for the class was a Yoyodyne 47B M/ARC Warp Core, two HeliosCorp Hyper Impulse Engines, two Inline Flux Secondary Impulse Engines on the primary hull, and two HeliosCorp HERMES-type Impulse Maneuvering Manifolds.

### Science and remote sensing systems

Ten DYN-90 Multi-band Linear Sensor Suites, four Omniwave Passive Sensor Matrices, and a J-DOME Active Omni-Directional Sensor Array were equipped on vessels of the class.

### Auxiliary systems

In addition to a dedicated transporter in the aft portion of the bridge, the *Sojourner*-class featured transporters at strategic locations throughout the ship.

### Auxiliary craft systems

As with the *Odyssey*-class, the main shuttlebay of the *Sojourner*-class was situated on the aft rim of the primary hull between the impulse engines. The class also carried a specialized berth for an embarked *Aquarius*-class corvette in the aft section of the secondary hull.

### Crew support systems

Holographic projectors were equipped throughout *Sojourner*-class vessels. These allowed for emergency holograms to be quickly activated at any location in a time of need. As such, the starship's computer stored the programs for six Emergency Medical Holograms, six Emergency Engineering Holograms, and eighteen Emergency Security Holograms.
