Integrated Air and Missile Defence

Integrated Air and Missile Defence

The threats facing commanders in the defence and security domains remain challenging and uncertain, while the capabilities and forces at their disposal have never been more complex.

At L3 ASA we understand this complexity and recognise the absolute need for capability integration, interoperability and system agility at every C2 level.

We have delivered decision support tools across the air and missile defence environments, developing a reputation for overcoming the most demanding information and data fusion challenges.

Our core C2 products are modular, scalable and adaptable to suit any operational timeline, with a proven pedigree of safety and security assurance that can only come from fielding within operationally mission-critical systems.

Above all, they provide the practical means to integrate force elements across the battlespace.


L3 ASA is responsible for producing the “Situational Awareness Component” (SAC) for the UK’s Land Environment Air Picture Provision (LEAPP), Counter Rocket Artillery and Mortar (CRAM) and Automated Sense and Warn (AS&W) systems. All these systems produce a Local Air Picture (LAP) or Local Air and Missile picture using TOTS to fuse data from locally-connected sensors and to correlate this with the LAP’s from other system nodes as well as with the Recognised Air Picture (RAP) provided by Link 16.


ASA provided experimental TOTS-based tracking systems for a series of Integrated Air Defence Combat ID exercises in the US to demonstrate the benefits of TOTS’s data fusion approach in maintaining combat ID with data from multiple radars in a complex air and missile target environment.
