A stock rocket called Zephyr. Built in the KSP 1.11.2 VAB with 89 stock parts.

I packaged Zephyr some time ago with Mosquito Javelin, replacing the original Javelin lifter therein, but here it is now, separately, in its own right.

75 tons dry load to orbit or 170 tons borrowing fuel from the payload; very versatile! I am now using it whenever I can.

It is based on the fundamentals of Atkara’s Mk1a Launch Vehicle with a few alterations. Certainly, please look at his design, too.

Simplified Recovery Procedure:
* lower orbit to 70x70km
* at 110W, lower PE to NEG 260 km; SAS Radial Out
* purge all fuel except the for'ard tank (1350 LF); move fuel to the aft tank
* turn Prograde when unable to hold Radial Out, moving fuel for'ard
* when maneuvering speed is attained, split the fuel between the two S3s
* maneuver to land using thrust as necessary
* preparing to land, jettison all fuel
* throw the drag chutes. they may be cut with [9] if desired
* gear down and brakes set to land. Throw main chutes over the runway
