The first contract extends MDA's unmanned aerial vehicle surveillance service for the Australian force in Kandahar Airfield for an additional two years.
The second contract provides for a three month assessment activity that will provide critical information in support of Australia's efforts in Afghanistan.
The Richmond-B.C.-based company says the combined contract value of the two deals is in excess of $100 million.
MDA has been supporting the Australian forces by providing important real-time intelligence, surveillance and reconnaissance information to ground commanders since January 2010.
MDA delivers a spectrum of information solutions, ranging from complex operational systems, to tailored information services, to electronic information products.
