Prometheus was the Titan that gave fire to man, in essence, technology.
Prometheus - Designed to conquer low Kerbin orbit; can put 50+tons of payload into a 250 KM orbit w/ 600m/s dV left over for orbital maneuvers. Also capable of down orbiting 50tons of payload for reentry and safe landing at KSC. Can also be launched w/o payload and sent to Mun or Minmus should you so choose (why send wings that far out though?) or trade payload mass for more fuel (external tank is only half full) and put ~30 tons into a 120KM orbit at 3.2X scale.
Utilizes SRB's, each SRB is made up of 13 kickbacks each, thrust limited in pairs to provide a thrust curve over time giving incredibly stable control throughout the 1 min 55 sec burn. SRB's are equipped with 8 cubs and some LFO to provide critical gimbal capability to the SRB, further smoothing control. They are also fully recoverable. 335ton gross mass, 75 ton empty, each. So the only launch expense is the External Tank and fuel. *The blue dots are Mk16XL parachutes.
The high dihedral angle of the wings provides perfect stability throughout reentry, approach, and landing. The canted stabilizers can add additional pitch authority for high mass payload returns. Utilizes 2 pairs of aerospikes for primary orbital maneuvering and a pair of Puff engines for docking maneuvers.
*NOTE: This craft is not on KerbalX. It must be flown as designed which requires an instructional video. It has also taken a LOT of time to develop, specifically the SRB's in order to create the thrust curve and have it be stable so I am not in a rush to give that away.
