Strawberry-5

The Strawberry 5, S-5, or as it is officially known (Unuvi: Kamei Hvàvichahye-5 Kizhakea, lit. Kamei Strawberry-5 Commercial Spaceplane), is a 20-seater sibling crosser developed in the Nautical Peace by Kamei Ultraheavy Industries. It was the first member of the Strawberry family made commercially available and remains the most widespread sibling crosser of all time.

The Strawberry-5 was a major factor in the plummet of intersibling transport costs, and is celebrated as the 'spaceplane that began the era of mass-spaceflight'. It is fully resuable and, unlike other early spaceplane designs, is uniquely easy to repair with common tools and materials. It also held the record for safest sibling crosser of all time until it was surpassed by later models of the Strawberry family.
