Major Data Source:  Orion Sector Intelligence

The Ohmera class of patrol ship is one of the few standardized classes of ships in the Orion Frontier Mercantile Association (located in the Triangle) or any other Orion government. Constructed in and around the Rigel system near the Orion home world, the 25 B-1’s were then transferred to the OFMA for patrol and system defense. It is reported that some 150-odd more ships of this class are elsewhere in Orion controlled space, some of which have been given various design modifications in keeping with usual Orion practice. Loosely based on some older Orion blockade runner designs, the Ohmera class is able to catch anything it can defeat in battle and run away from anything that it cannot. Her nine disruptors are placed in three groups of three each located on the bow and one on each side of the hull. These weapons are fired independently by gun crews near their weapons. One shuttlecraft is usually carried on these vessels.

The Ohmera class patrol ships are usually seen in and around the systems of the OFMA. They are used mainly as police and customs ships by the carious corporate interests in the area, although they are considered a part of the permanent Navy of the Orion Frontier Mercantile Association. These ships have also been seen as convoy escorts on the more dangerous trade routes within the Triangle, but this is rare. Interestingly, rumors are becoming more widespread that OFMA Ohmera ships have, on occasion, been involved in some “privateering” of their own in the usual Orion fashion. This has never been proven, however, and these vessels are still considered part of a bonafide Navy rather than as pirates.

It is reported that some ships of this class were patrolling the Workday system during the recent “Devon Incident.” The explosion of this Federation warship seems to have caused considerable damage to the facilities there, including the loss or crippling of at least one vessel of the Ohmera Class.

Like many Orion vessels, production of the Ohmera class has slowed and is now by contract only. Of the estimated 175 hulls built so far, only 60 are officially registered for sale along with the 25 currently in use by the OFMA. Reports from the Klingons indicate that they have captured several of these vessels. The Romulans are known to have destroyed two, although who owned those vessels remains a mystery. The IKS is rumored to own several, including 5 A-1s and possible a B-1. It is unknown if these were traded or captured. Ohmera Arms of Rigel originally owned the design patent until 2281 when it was sold. The current design holder is unknown.
