Lockheed Martin Selects Aonix PERC Virtual Machine for Aegis Weapon System
High productivity, determinism key to Aegis Open Architecture Program
Oct 11, 2006 - 17:50 PM
The Lockheed Martin Aegis team was faced with programming language selection for its Open Architecture Program. Java™ was selected for several critical subsystems due to its superior tool and library support along with its superior productivity and portability. However, traditional Java offerings could not meet the challenge of the critical timing requirements for the Aegis project. In contrast to its competitors, PERC Ultra, with its deterministic capabilities and ahead-of-time compilation, offered Lockheed Martin the responsiveness it needed to meet its most demanding timing requirements. In addition to real-time threading and deterministic garbage collection, PERC Ultra provided the instrumentation and VM management tools necessary to support the mission-critical real-time requirements of the Aegis Weapon System.
“While increased developer productivity is a major motivator for using Java, most Java solutions lack the predictable performance required for mission-critical applications,” said Dave Wood, Aonix marketing director. “The experience of the Lockheed Martin Aegis program is yet another in a string of successes proving that PERC solves both the productivity and performance aspects of the equation for embedded Java developers.”
The Lockheed Martin-developed Aegis Weapon System is the world’s premier naval defense system and the sea-based element of the United States’ Ballistic Missile Defense System. The Aegis Weapon System is a radar and missile system seamlessly integrated with its own command and control system, capable of simultaneous operation defending against advanced air, surface and subsurface threats.
Currently, Aegis Weapon System capabilities are on 80 cruisers, destroyers and frigates on station around the world, with more than 25 under construction or planned. In addition to the U.S. Navy, Aegis is the primary naval surface weapon system for Japan, Spain, Norway, Korea and Australia.
First introduced nine years ago, PERC Ultra is the most widely used real-time virtual machine available for Java™ developers, with fielded installations in telecommunications, telematics, avionics, deep space exploration, industrial automation, military, and office automation applications. PERC supports most major real-time operating systems and a variety of target processors including PowerPC, XScale, ARM, and Intel x86 architectures.
