Boeing is considering bringing back the OV-10 Bronco due to increased global interest in a light strike aircraft of this type.
The last combat engagement for United States Broncos was in Operation Desert Storm. As the Bronco was originally designed for the rigors of tropical jungle operations, Desert Storm proved to be an "acting experiment" for the Bronco system. Some in the USAF were even reluctant to field the type for fear that the system would not match well in the modern conflict across unforgiving desert terrain. Nevertheless, the USMC sent their Broncos into Saudi Arabia making up USMC VMO-1 and VMO-2. In the conflict, the first aircraft lost to enemy fire was an OV-10A from VMO-2.
As of this writing, interest in the OV-10 series is growing to the point that talk of restarting the production lines have been tossed about for both domestic and global markets. Boeing is currently considering such plans and would involve a complete redesign of the internal systems to bring the Bronco up to modern status. These revisions would include a complete all-digital cockpit and support for "smart" guided munitions. By all accounts, the external appearance of the new Bronco would stay the same as their Vietnam-era brethren.
