Also under NASA's CCDev program, SpaceX was awarded $75 million for the development of their own version of a "pusher" LAS. Their Dragon 2 spacecraft will use its SuperDraco engines during a launch abort scenario. Although often referred to as a "pusher" arrangement since it lacks a tower, the Dragon 2 LAS removes both the capsule and its trunk together from the launch vehicle. The system is designed to abort with the Super Draco engines at the top of the abort stack as occurs with a more traditional tractor LAS. The concept was first tested in a Pad Abort test conducted at SLC-40, Cape Canaveral Air Force Station, on May 6, 2015. SpaceX tested the system on January 19, 2020 during ascent of the Falcon 9 rocket in Kennedy Space Center Launch Complex 39 from where it has launched crews to the International Space Station.
