L-3 Communications announced that its Integrated Systems division (L-3 IS) has been selected as the preferred contractor by the New Zealand Ministry of Defence to upgrade mission and communication-navigation systems for New Zealand's fleet of P-3 Orion (P-3) patrol aircraft. The upgrade to the six aircraft operated by the Royal New Zealand Air Force will include the replacement of the data management system, radar, electronic sensors, communications and navigation systems. The upgraded P-3 fleet will be equipped to meet both civilian agency and military requirements, as well as provide interoperability with New Zealand's security partners. Contract value will be determined through negotiations which are under way now and expected to conclude in October.
