Long Wall Space (formerly ABL Space Systems)

ABL Space Systems (now doing business as Long Wall Space) was founded in 2017 in El Segundo, California. The company developed the RS1 rocket, a 1,350 kg payload two-stage orbital launch vehicle using liquid oxygen and kerosene engines. ABL rapidly iterated its vehicle using modular, rapidly-deployable ground support equipment to minimize infrastructure at launch sites. The company has conducted initial RS1 test campaigns and is working toward commercial orbital missions, targeting the dedicated small satellite launch market.
