This is accurate as of USI Kolonization Systems (MKS) version 1.4.1

The Tundra series contains larger, more permanent parts, that can be used for planetary or orbital stations. Many of the components come in both a 2.5m and 3.75m configuration.

The parts can be found in the VAB and SPH in several locations:

• Kolonization
• Manufacturing

Many of the Tundra parts are modules that have the same form factor. The only external differences are the number and image shown on the side, and some come in more than one size. Each module provides specific services and some can be configured to perform different operations. They can be connected sing the various hubs and stands, as shown in these examples:

---

These are the primary parts that are used on most bases, supporting the key MKS goals and allowing parts to be connected. They are found in the Kolonization tab in the VAB and SPH.

A tube suitable for connecting various MKS modules. Attachment styles include 'Ranger' style doughnut connectors, standard 1.25m nodes, and flush mounts suitable for linking trusses together, or attaching to larger surfaces.

Two variants of the truss are provided. The larger MultiTruss has two connection points on each side while the smaller MiniTruss has a single attachment point on each side.

Note that as of KSP release 1.10, MKS uses the stock welding capabilities to attach items.
