A simple 5 seats shuttle, able to ensure crew transfers and to reach the Mun or Minmus
Vishnu got a particular place for me. Named after the famous divinity of Time from the Hindu mythology, the X-21A was originally developed to study lifting bodies and an efficient wing. Not too heavy but sufficiently potent to ensure a stable re-entry and descent. The final result now is good as the craft is braking softly but surely and without touching any controls, the S.A.S ensuring the work by itself. But, it always be better to transfer the remaining fuel to the nose if possible.

The launch sequence for itself is pretty easy. Propelled by a Mainsail and four Thud the main stage is more than maneuverable for any request while the pair of Kickback is ensuring a good acceleration. After only 62 seconds the S.R.Bs are ejected with the support of their Sepratron.
The main stage then is able to put the apogee at 300 km and circularize. Some fuel still being available for the next maneuver.

Once in orbit the spacecraft got around 2.6 km/s of impulsion available, enough to visit the Mun, circularize around then transfer to Minmus, circularize once again and finally come back to Kerbin. Or a visit to just one of them if you want to keep enough fuel for re-circularizing around Kerbin.

Equipped of one braking chute and three parachutes, the X-21A can be landed the classic way at the K.S.C runway or make a vertical and soft landing anywhere else under its slings.

A stock rocket called Sleg X-21A Vishnu. Built with 109 of the finest parts, its root part is Mark1Cockpit.

Built in the VAB in KSP version 1.3.0.
