Roberts Space Industries (RSI), founded in the early 21st century SEY, is one of the oldest and most influential space technology companies in the United Empire of Earth (UEE). Spacecraft, spacecraft components, and terraforming technology make up the bulk of their products. In 2075, RSI created the quantum core engine, and in 2113, the company released the earliest terraforming machinery utilized by Humans. RSI entered a period of decline during the Messer Era (2546 - 2792), when their military contracts were terminated in favor of Aegis Dynamics, and further shrank 2757, when Ulysses Messer X publicly blamed the company for the death of Anthony Tanaka. It wasn't until the end of the Messer Era that RSI's military contracts were reinstated. Today, their Bengal line of carrier ships and Pegasus line of escort carriers are utilized by the United Empire of Earth Navy (UEEN).
