The KV-1 'Onion' Reentry Module is a Command Module housing one Kerbal crew member during their mission. It has a rounded shape, similar to an onion or Stayputnik.


Generally placed at the top of the rocket, the KV-1 Onion provides basic command module functionality.

It features a 0.625 m radial size node on top, typically used for parts like the Mk16 Parachute, docking ports, service bays, or SAS modules. On the bottom, it has a 1.25m radial node. As the node is part of the heatshield, it includes a "free" decoupler. This decoupler does not take up any additional mass, but can only be fired if the pod is attached to something else.

Notably unlike the previous pods, the KV-1 has a small heatshield integrated in, no monopropellant, and no reaction wheels. The last one requires extra care in craft design, else a mission could be curtailed or lost due to limited control options. Against the the Mk1 pod specifically, it is comparable in cost (590 funds vs 588 with all resources removed), can handle somewhat higher temperatures (both in general rating, and the aforementioned heatshield), has a slightly lower impact tolerance (12 vs 14 m/s), and is and marginally lighter (0.75 vs 0.8 tonnes without resources).

Product description

The design bureau cried when the finance department cried "that's your lot!"



  • The part's CFG file suggests that this capsule was originally named "Shallot".

Real-world comparison

The KV-1 was inspired by the Vostok.
