Bespan

The Bespans were a spacefaring race whose homeworld was located in an unexplored nebula within the Typhon Sector

First Contact
First contact was officially made with the Bespans when one of their vessels arrived outside of Outpost 119 around Stardate 68056.22. At that time, the captain of the Bespan ship exchanged pleasantries with Outpost 119's Commander D’Jal and said a diplomatic representative would return shortly.

The NX-76948 Incident
The next contact with the Bespans occurred on Stardate 68097.5 when a Bespan vessel appeared at Outpost 119 and began attacking. An unsuspecting Starfleet Saber Class cruiser arrived at nearly the same time. That ship, known only as NX-76948 was on a secret R&D mission for Starfleet Intelligence. It's skeleton crew was caught off-guard and overpowered. Once in control of the Federation vessel, the Bespans fled back toward their home world.

The USS Bellerophon was dispatched to the outpost and pursued the stolen vessel. The Bellerophon crew was able to recapture the NX-76948 and returned it and several Bespan prisoners to Starbase 719.

Appearance
The Bespans encountered by the Bellerophon crew were all male. They stood about two and a quarter meters tall and were solidly built. Their skin was mostly blue, but there were what appeared to be red markings on the sides of their faces. Rather than hair, their heads were topped with a ridged crest.

Technology
The Bespan vessel that attacked Outpost 119 was about the size of a B’rel-class Klingon Bird of Prey It fired a type of rail gun that used a radioactive isotope as its base ammunition. The vessel's maximum velocity was Warp 5.

Following the attack on Outpost 119, the Bespans deployed a device that jammed communication within a 25,000 kilometer radius. The device, only 10 centimeters in diameter, also had a sensor aversion technology that made it impossible to lock transporters or tractor beam on it. The Bellerophon crew were eventually able to temporarily disable it with a non-targeted, wide-spectrum burst of verdion particles.
