Stockholm-based Enea said Lockheed Martin U.K. selected its Polyhedra database management system for use in the Merlin Capability Sustainment Program (MCSP). Financial terms of the deal were not disclosed. Lockheed Martin UK serves as the prime contractor for MCSP, a multiyear project to upgrade the weapon system in the Royal Navy’s Merlin helicopter. The project aims to utilize open systems technology to reduce full-life-cycle cost of ownership, facilitate technology refresh and insertion and improve the helicopter’s mission system display and radar/sonar capabilities. The first flight of the upgraded helicopter is planned for 2010. Polyhedra will be used to provide real-time data storage and management for the Merlin Helicopter’s Tactical Mission Computer (TMC) System. “As avionics software becomes more complex, developers are finding it increasingly more difficult to provide reliable, high-performance data management using home-grown solutions,” said Virginia Walker, senior vice president of corporate strategy and marketing at Enea. Enea said Polyhedra provides a persistent, fault-tolerant data repository for embedded systems applications. Polyhedra’s event-driven technology makes databases more robust, simplifies applications and enhances performance, the company said.
