The U.S. Air Force and Army have jointly developed a lightweight electrical power system that can be transported by air to serve provisional bases. The engineering contractor for the new Deployable Power Generation and Distribution System chose S&C Vista Underground Distribution Switchgear, Chicago, for primary switching and secondary distribution. The SF-6 insulated Vista UDS is small and lightweight, making it suitable for airlifting.

All of the units have a 600A continuous current rating and 16kA short-circuit and fault-interrupting capabilities. Each unit includes two load-interrupter switch ways and four fault-interrupter ways. Optional voltage indicators are also included.
