Compiler system speeds combat system
design
SSDS Mk 2 is a combat system that integrates and co-ordinates the sensors and weapons systems aboard a US Naval vessel to provide a coherent tactical picture.
Raytheon has delivered the Ship Self-Defense System (SSDS) Mk 2 using Gnat Pro for LynxOS within its multilanguage software development environment SSDS Mk 2 is a combat system that integrates and co-ordinates the sensors and weapons systems aboard a US Naval vessel to provide a coherent tactical picture for situational awareness, command and controls, and quick-reaction self-defence

Development environment upgrades to Ada 2005
The latest and most advanced version of the Gnat Pro open-source Ada development environment supports all the major new features in Ada 2005.
It is a single-source baseline that supports multiple system configuration modifications (MODs) for large deck ship classes (aircraft carriers and amphibious ships).
Gnat Pro was specifically used on the SSDS Mk 2 to support Ada application development on the Intel processors and the LynxOS operating system.
"SSDS Mk 2 is a modular distributed program consisting of C, C++ and Ada software components", says Mark A Hodge, SSDS Mk 2 Technical Director for Raytheon Integrated Defense Systems.

"LynxOS for x86 was selected because of its real-time determinism as we migrated from an older operating system towards a more mainstream OS.
The AdaCore Gnat Pro compile system was selected both for its support for LynxOS and its association with Gnu, which is being used for the C and C++ application components".
"AdaCore's Gnat Pro tool set provided Raytheon with the seamless interoperability it required to support the inherently mixed-language development of SSDS Mk 2", says Robert Dewar, President of AdaCore.
"On large, mission-critical systems, Ada is often used in conjunction with other languages, and the Ada design specifically caters to such usage".
"AdaCore provides complete support for compilation with multi-language build and debug for all Gnat Pro environments".
On many of today's amphibious ships and aircraft carriers, the radar and anti-air weapons used for self-defence are installed as stand-alone systems.
As a result, considerable manual intervention is required to complete the detect-to-engage sequence against anti-ship cruise missiles (ASCMs).
SSDS Mk 2 is designed to expedite that process.
Consisting of software and commercial-off-the-shelf (COTS) hardware, SSDS Mk 2 integrates radar systems with anti-air weapons, both hard kill (missile systems) and soft kill (decoys).
SSDS Mk 2 includes embedded doctrine to provide an integrated detect-through-engage capability with options ranging from use as a tactical decision aid to use as an automatic weapons system to respond with hard-kill and soft-kill systems.
Although SSDS Mk 2 will not improve the capability of individual sensors, it enhances target tracking by integrating the inputs from several different sensors to form a composite track.
For example, SSDS Mk 2 will correlate target detections from individual radars, the electronic support measures (ESM) system (radar warning receiver), and the identification-friend or foe (IFF) system, combining these to build composite tracks on targets while identifying and prioritising threats.
Similarly, SSDS Mk 2 will not improve the capability of individual weapons, but should expedite the assignment of weapons for threat engagement, and provide a "recommend engage" display for operators, or if in automatic mode, initiate weapons firing, ECM transmission, chaff or decoy deployment, or some combination of these.
SSDS Mk 2 integrates previously "stand-alone" sensor and engagement systems for aircraft carriers and amphibious warfare ships, thereby supporting the Joint Vision 2010 concept of full-dimensional protection, by providing a final layer of self-protection against air threat "leakers" for individual ships.
By ensuring such protection, SSDS Mk 2 contributes indirectly to the operational concept of precision engagement, in that strike operations against targets are executed from several of the platforms receiving SSDS Mk 2.
