Vector Acquisition Corporation was established in 2020 as a special purpose acquisition company, operating out of San Francisco, California. Its primary objective involved pursuing and executing a strategic business combination, such as a merger, stock exchange, or asset acquisition, with an existing enterprise. The firm successfully completed this mission by merging with Rocket Lab USA, Inc., a prominent entity in launch and space systems, in August 2021. Following this transaction, the company adopted the name Rocket Lab USA, Inc., and its shares subsequently began trading under the ticker symbol RKLB on the NASDAQ exchange.
