Based on the Mercury-Class from Star Trek Online which itself is a futuristic variant of the Defiant from DS9. Added the Nalroni 'star wars phasers turrets' that look a bit like the NX-class' phase cannons and greebled it up.
*170m long hybrid of a system-patrol craft and a frigate.
*Massive forward-facing firepower using the Nalroni particle beam turrets and turbolasers.
*The blue glowing 'eye' in the center had two coaxial mass-driver cannons which use the oval-shaped magnetic pads infront of it to propel a 1.2m wide slug forward at incredible speeds.
*Can carry two Vertex-class fighters in its ventral hanger bay.
*Has a very small, cramped crew. Most systems are only accessible via small crawlspaces that droids would maneuver through to make repairs.
*Extremely thick 1.6m Ceramisteel-Durasteel armor.
*Shield emitters focused around the center of the ship allowing an even distribution.
