My build of the Prometheus II LLV (Leo Launch Vehicle) rocket is Blue Dog Design Bureau’s equivalent of the Titan II GLV (Gemini Launch Vehicle) along with the Leo spacecraft which is analogous to the Gemini spacecraft. The load has been somewhat reduced to give a wider margin of error for newer players including a reduction of the ablative shield, removing about half of the monopropellent, and reducing some of the fuel from the second stage.
This craft can simulate aspects of the earlier Gemini missions such as the maiden voyage of Project Gemini, Gemini 3. However it also includes a docking adapter not otherwise available until Gemini 6 and 7 and enough monopropellent for rendezvous and docking missions as well as fuel cells which weren’t available until Gemini 4.
I recommend an apogee of approximately 150km especially if you intend to perform any rendezvous and docking missions as it gives you plenty of room for orbital maneuvers. The second stage has two pairs of retrograde rockets which should put the spent stage into a decaying orbit to eliminate orbital debris.
The ascent profile is fairly simple but due to a relatively low thrust-to-weight ratio (TWR) the ascent will be somewhat inefficient and require around 4000 dv to achieve an orbit of 150km. There may be unexpected yawing and other effects in the beginning of the second stage and again when you clear the atmosphere but not enough to cause any serious problems.
The re-entry procedure requires you to decouple the Medici service module and needs to be accomplished manually or through the hotkey as for some reason it can’t be staged (unlike the Gemini service module in FASA). A more recent patch has made it so, in theory, it can be staged but I still recommend it be done manually as it seems to be buggy sometimes.
Built in the VAB in KSP version 1.3.0.
