Falcon-9 v1.2(ex) (EchoStar 23)
Falcon-9 v1.2 or Falcon-9FT is a liquid fueled orbital launch vehicle for medium sized missions, which is developed by SpaceX (Space Exploration Technologies Corp.). It is a improved version of the Falcon-9 v1.1(ex) launch vehicle without reusable first stage for increased performance. Both stages are Kerosene / LOX fueled.
The Falcon-9 v1.2 is mostly identical to the Falcon-9 v1.1, but features some improvements. The Merlin-1D are uprated to provide thrust increased by 15%. Propellant densification is introduced to increase the fuel load and the upper stage tank volume is increased by 10%. This results in overall 30% increase in performance, alowing stage 1 recovery also on GTO launches.
The first stage is powered by 9 of the SpaceX built uprated Merlin-1D engines with regenerative cooling. The Falcon-9 is offered with a 5.2 m fairing.
Launch site for low inclination launches is Cape Canaveral launch pad SLC-40. High inclination launches are performed from Vandenberg AFB launch pad SLC-4E. An additional launch site at Boca Chica near Brownsville, Texas, is also under construction.
The expendable version is only used for rare cases, where the full performance is needed, so that no fuel for the powered landing remains.
