Description
A stock rocket called Kerbal X3a. Built with 93 of the finest parts, its root part is mk1-3pod.
Almost exactly the same as the Kerbal X3, with the only substantial difference being the replacement of the X3’s second-stage Poodle engine with the more-efficient and much-more-powerful Wolfhound, allowing the X3a to hold a lower pitch angle than the X3 during orbital insertion (reducing cosine losses) in addition to increasing its fuel efficiency directly (through the Wolfhound’s greater specific impulse).
Built in the VAB in KSP version 1.10.1.
