Continuing pressure on the military services to become more interoperable and for their weapon systems to be more compatible is the driving force in most defense acquisition programs today.

A case in point are unmanned air vehicles, which rapidly are gaining acceptance and accolades for their role in helping commanders scope the battlefield and find targets. But like most defense systems in the current inventory, UAVs from different services cannot share information or communicate with one another. Each type of UAV also requires unique command and control systems.

With 138 different UAVs in production today, the time has come for the Defense Department to enforce common standards for the operation, command and control of these vehicles, said a study sponsored by the Air Force deputy chief of staff for war-fighting integration. The Air Force is concerned that, as more UAVs from every service join the battle,

it will become increasingly difficult to manage and coordinate air combat operations, and that keeping trained operators and maintainers for each system will drive up the cost of employing UAVs.

On the tactical communications front, the lack of interoperability among military radio systems has been a problem in the field for many years. That prompted the Defense Department to launch the Joint Tactical Radio System program, in an effort to consolidate 750,000 military radios into a single family of software-programmable devices.

The $3 billion JTRS program, however, is experiencing a few hiccups along the way, given the technical complexity of the project and the services'...
