The BTG II is a small capsule meant for basic LKO (Low Kerbin Orbit) operations including basic rendezvous and docking. It’s meant to be a fairly simple ferry or emergency pod that can house up to (3) Kerbonauts at a time. It’s equipped with a service module with monopropellent engines and several small solar panels to recharge the craft.

The BTG II launcher is based after a number of Ariane launchers such as Ariane 3 and 4 but has been simplified with only a single main stage combined with four boosters. The boosters only last a couple of seconds and are meant to only help with the initial launching, afterwards they are decoupled while still in the lower atmosphere. The main stage handles the rest of the ascent and the circularization, which I recommend an initial orbit around 100km. Unfortunately this will leave the main stage as sufficient orbital debris.

The craft itself has fairly monopropellent engines, rated at around 110 kN, and a very large quantity to allow for extensive orbital changes including extreme inclination changes. It should be able to reach any target in LKO and potentially also targets in either MKO (Medium Kerbin Orbit) or HKO (High Kerbin Orbit). It’s equipped with a CIDAS A-9 docking port, although this could be replaced with similarly sized docking port.

One of the more unique features of the BTG II is that it possesses heat shields for both the service and crew modules. This means the service module can be left on during atmospheric re-entry and could even potentially land with the crew module. It could also be left on as an emergency backup if confidence in the crew module’s heat shield has been compromised. The triple parachutes are located at the top of the crew module and are deployed in the lower atmosphere.
