The Royal Australian Air Force will receive rapidly deployable air traffic management and control systems from Indra Australia.

The two systems, plus a larger one, are being procured through a contract worth more than $43.7 million.

"Recent global events have seen Australia's air capabilities come to the fore to assist our friends and allies ...," said Minister for Defense David Johnston said.

"These deployable air traffic control systems will enhance the RAAF's future operations both overseas and domestically."

Johnston said the systems, which will help Australia's military manage airspace during humanitarian assistance and disaster relief missions as well as deployed combat operations, will also benefit the country's economy by providing employment opportunities during the integration and through-life support phases of the deployable air traffic control project.

Additional details of the contract were not disclosed.

Indra Australia is a subsidiary of Indra Sistemas and specializes in air traffic management systems, navigation systems and electronic warfare solutions.
