The C-37A/B are twin-engine, turbofan aircraft acquired to fill the worldwide special airlift missions for high ranking government and Department of Defense officials.

The aircraft contains a modern flight management system with a worldwide satellite-based Global Positioning System and comes in two variations. The C-37A is based upon Gulfstream V aircraft and the C-37B is based upon Gulfstream 550. Both are capable of high-altitude, intercontinental flight with cruise operations from 41,000 to 51,000 feet.  Features include enhanced weather radar, autopilot, and an ultra-modern heads up display for the pilot. Safety features include Enhanced Vision Systems that allows increased visibility in poor weather conditions. The aircraft is also equipped with both commercial and military communications equipment to provide secure and non-secure voice and data capability.
