Description

After the official decommision of the super sonic reconaissance jet KR-71, she has been repurposed by restructuring her fuel bays and adding twin dual-purpose RAPIER engines. Now she can deploy small surveyance orbital probes, or bring small amounts of snacks to your Kerbal Space Stations.

Only the Panthers are needed for takeoff. In order to conserve fuel, start them in normal mode, switching to afterburning when reaching about 75m/s. Set the climb to a effective 8-10ยบ. At about 4000m, fire the airbreathing mode of the RAPIERs. About 20-21km, switch the RAPIERs to closed cycle. When you reach about effective 40km (NOT 40km apoapsis), hold prograde until your apoapsis is about 90-95km. Then circularize etc etc.

For the reentry, not much to say. If your inclination is close to 0, when reaching Woomerang longitude set the periapsis to 35km approximately. This should keep you a bit short to the mountains next to the KSC.

With FAR, the landing is complex. The plane needs quite high speed to keep herself flying, and below 180m/s it a bit difficult to handle. Align with the landing strip as soon as you can after passing the mountains, trying not to touch much the controls. The added stability from FAR assistance is much advisable. Brake with all you got, and deploy the chute immediately after (or just before) touching the ground.

A mod aircraft called KRB71 mk7. Built with 101 of the finest parts, its root part is mk2FuselageLongLFO.

Built in the SPH in KSP version 1.8.1.
