Description

Collapsar is a stock spaceplane SSTO that, in fact, comes in three variants. Each of them is about 230 meters long, consists of ~1.4k parts and weights about 9600 tons if fully loaded.
243 R.A.P.I.E.R. engines, 4 Mammoth engines and 4 Goliath engines consume about 20.5 tons of fuel each second on takeoff. Total atmospheric thrust peaks at about 130 000 kN.

This is a version of the craft with bigger cargobay (fairing, actually). Use closed cycle of rapiers paired with mammoths on takeoff. Dont try to takeoff from the KSC runway with craft weighing more than 7600 tons. Use polar ice caps for that.

KJR MOD STRICTLY RECOMMENDED!
