The Porcupine class destroyer is a relic of a bygone era. The first Porcupines were ubiquitous during the Solar War, serving in both Terrestrial and Colonial navies. Ships of this class were fielded in especially large numbers by the Martian and Jovian powers because of their relative hardiness.
 

These ships are little more than heavily armored gun platforms. Each destroyer is equipped with eight twin-barreled autocannons along its equatorial radius, as well as four box missile launchers (four tubes each) located two each dorsal and ventral.
 

The Terran Navy acquired a number of Porcupines (15 in total) from various member nations in the first five years after the Commonwealth Charter was signed. These forces formed the core of the early Commonwealth naval forces and were the entirety of its force until 2189.
 

The original Porcupine-A (ISD: 2154) was slower and possessed less efficient weaponry than the Porcupine-B. The Commonwealth began refitting its fleet of Porcupines to the “B” standard in the early 2190s, completing the refits by 2198.
 

The final two Porcupines in active Commonwealth service, TCS Sea Lion DD-4 and TCS Mongoose DD-11, were mothballed at Sol in 2228.
 

Despite being obsolete by the standards of the Terran Navy, some independent terrestrial nations and colonies continue to operate destroyers of this class. For instance, as of 2238, the Mars Libertarian Militia fielded a fleet of four Porcupine-B destroyers.
 

The class earned its name based on the number of radiator and sensor spikes that emanate from its bulbous hull, making the ship resemble a porcupine. As such, ships of the class were named for tenacious or annoying animal life (Badger, Raccoon, Wolverine, Tasmanian Devil, etc.).

Named for the Greco-Roman god, the Apollo class of light cruisers was the first new warship class to be deployed by the Terran Navy in the interstellar era. The Apollo was conceived as a short-range defense vessel that could be deployed to protect the Commonwealth’s fledgling colonies. One of these cruisers is larger than a destroyer, and commensurately better-armed. This makes them a more formidable opponent for lowly raider threats, this class’ intended adversary.
 

Because of its primarily anti-piracy fleet role, the Apollo class is not as large or as durable as an Atlatl or other heavier cruiser class. However, the class is far more economical to build and maintain than other cruisers. In some circles the Apollos are referred to not as cruisers but as heavy destroyers; while their official designation is as a light cruiser, heavy destroyer is actually a more apt name for the warship given its capabilities.

A notable weakness of this class is its lack of a FTL Drive. This necessitates the class to rely on civilian jump stations to move between systems, or else the assistance of FTL-capable Jump Carriers (such as those of the Marathon class).
 

Within the first year after conception, a group of nine Apollo cruisers were launched. These vessels formed the backbone of the Commonwealth’s frontier defense force, supplementing the Afridi and Fletcher destroyers already on patrol in these areas.

Ships of this class are named for places and figures related to the myth of the god Apollo.

The Europa Light Carrier was developed as a stopgap solution to the Commonwealth’s need for a new, modern carrier prior to the development of a replacement for the aging Eisenhower Heavy Carriers. Because of its unabashed existence as a transitional hull, the Europa class was designed to be a light carrier that would be smaller and less capable than a heavy carrier, but also quite a bit cheaper to build and maintain.
 

Ships of this class are named for the moons of Jupiter.
