Adamant class

The ***Adamant*-class** was a type of spacecraft developed by Starfleet in the early 25th century. It was derived from the *Defiant*-class, incorporated elements from Project Deep Shadow, and was developed alongside the *Valiant*-class. Starfleet rated the *Adamant* as a scale 3 destroyer and it often fulfilled an interdiction operations ship (IOS) role.

## History

While the *Defiant*-class had served with distinction since its introduction in the 2370s, it was found lacking during the events of the Iconian War. During its postwar evaluation, Starfleet Command determined that a new design was needed to fill the tactical role the *Defiant* had played. Two camps formed in the team tasked with the project. One side sought to expand upon the base *Defiant* frame, while the other designers advocated for a more radical departure. After initial presentations, both groups were given the approval to proceed with their ideas and the team split.

Those proposing a more drastic update to Starfleet's destroyer developed the *Adamant*-class, while those pursuing a a rebuild of the *Defiant* frame created the *Valiant*-class.

## Technical specifications

### Propulsion systems

Eight plasma vents, four for each warp drive unit, were situated on the dorsal side of the hull to allow for rapid ejection of warp plasma in emergency situations.

To aid in the *Adamant's* combat role, warp signature masking was incorporated into its drive. This system provided the vessel with superior stealth at ranges greater than fifteen kilometers.

### Science and remote sensing systems

Starships of the class were equipped with active sensor arrays, derived from Project Deep Shadow. Sensor instruments were located in seven pallets on the dorsal hull. The arrays allowed the destroyer to gather information about and expose vulnerabilities in a target in combination with the ship's active sensor probe (ASP).

### Tactical systems

The *Adamant*-class earned its destroyer classification with its heavy armaments. Each vessel mounted two Type-VII phasers, four Type-VIII phasers, six Type-X phasers, four Type-XII phasers, and launch tubes. Both the Type-VIII and Type-X units made use of Annular Confinement Beam-jacketing devices, allowing them to discharge between warp fields. An advanced cloaking device was also integrated into the design, providing a wide range of tactical and surveillance capabilities for each vessel.

One of the most unorthodox systems added to the class was its "wild weasel."

### Auxiliary systems

The transporter system was connected to five emitter pads on the exterior.

Holographic projectors were equipped throughout *Adamant*-class vessels. These allowed for emergency holograms to be quickly activated at any location within the vessel at the time of need. The class' small photonic core stored the programs for an Emergency Medical Hologram and an Emergency Engineering Hologram.
