ABL Space Systems is a private aerospace company based in El Segundo, California. The company was founded in 2017 by Harry O'Hanley and Dan Piemont, two former SpaceX engineers.
ABL Space Systems specializes in developing and manufacturing low-cost, rapid-turnaround launch vehicles and launch systems for commercial and government customers.
The company's flagship launch vehicle is called the RS1, which stands for Rapid Strike 1. The RS1 is a two-stage rocket that uses a combination of liquid oxygen and kerosene propellants.
It is designed to be highly mobile and can be transported to launch sites by truck or airplane. The RS1 is capable of launching payloads weighing up to 1,200 kg into low Earth orbit.
One of the unique features of the RS1 is its reusable first stage. The first stage of the rocket is designed to detach and return to Earth after liftoff, where it can be recovered and refurbished for future launches. This helps to reduce launch costs and increase the overall efficiency of the launch system.
ABL Space Systems has already secured several launch contracts with commercial and government customers, including the U.S. Department of Defense and NASA.
The company is also working on developing a larger launch vehicle called the RS2, which will be capable of launching heavier payloads into orbit.
