Defensive Aid Systems
Modern, robust technology
We are highly experienced in DAS design, manufacture and support.
Countermeasures Dispensing Systems (CMDS)
Petards Defence Services offer a full range of technical support services for Countermeasures Dispensing Systems (CMDS), including cockpit control, programming, build, installation advice, repair and servicing.
ALE-47 Threat Adaptive Countermeasures Dispensing System (TACDS)
We are the licensed manufacturer of the internationally renowned ALE-47 Threat Adaptive Countermeasures Dispensing System (TACDS), including the Pre-Flight Message creation and validation systems. TACDS is used by the Royal Air Force and the Royal Navy across a range of rotary and fixed wing platforms.
Petards Defence Services has supported the integration of the ALE-47 TACDS into the Common Defensive Aids Suite (CDAS) and NATO Defensive Aids Suite (NDAS) introducing Open Architectures and Common Message Sets between DAS equipment.
We have developed a Pre-Flight Message/Mission Data File Validation Facility for the ALE 47 TACDS, which is installed on the majority of the UK's military aircraft. This allows engineers to fully exercise a development PFM/MDF, including its integration with associated elements of a Defensive Aids Suite (DAS), before it is installed on an aircraft, enabling huge reductions in flight line testing and verification.
Support and test equipment
We also manufacture and supply a wide range of related support and test equipment including the Mk 6 Voltage Detector, WED 21329, NSN 6625-99-105-7080, (for which we are the Design Authority and hold IPR) and its range of associated Adapters and Interconnecting Cable Assemblies.
