===Scaled-down tests===

In January 2012, ISRO announced that a scaled prototype, called '''Reusable Launch Vehicle-Technology Demonstrator''' ('''RLV-TD'''), was approved to be built and tested.<ref name="FinalTouches2015">{{cite news |url=http://idrw.org/indias-futuristic-unmanned-space-shuttle-getting-final-touches/ |title=India’s Futuristic Unmanned Space Shuttle Getting Final Touches |work=EXPRESS NEWS SERVICE |publisher=Indian Defence Research Wing |date=20 May 2015 |accessdate=2015-05-20 }}</ref> The aerodynamics characterization of the RLV-TD prototype was done by [[National Aerospace Laboratories]] in India.

By May 2015, engineers at the [[Vikram Sarabhai Space Centre]] (VSSC) in [[Thumba Equatorial Rocket Launching Station]] were installing thermal tiles on the outer surface of the 'RLV-TD', so it can withstand the intense heat during [[Atmospheric entry|atmospheric reentry]].<ref name="FinalTouches2015"/> This prototype weighs around 1.5 tonnes and would fly up to an altitude of 70&nbsp;km.<ref name="FinalTouches2015"/> ISRO has tentatively slated the prototype's test flight from the first launchpad of [[Satish Dhawan Space Centre]] for December 2015.<ref>http://www.newindianexpress.com/states/kerala/RLV-TD-Mission-to-be-Delayed-At-least-Till-the-Year-End/2015/10/02/article3058357.ece</ref> The RLV-TD will be mounted on top of a rocketsolid booster HS9<ref>{{Cite web|url = http://www.sc.iitb.ac.in/~pdsc2014/MVD_talk.pdf|title = Modeling &Control of Launch Vehicles by M.
