An active countermeasure system for helicopter applications
SAAB PROPRIETARY INFORMATION
The objective
Complete the mission objectivesAchieve the same amount of landings as take-offs…Survivability• Increased Aircraft Combat Survivability (PS)
• Susceptibility to threats (PH)
• Maximizing PS = 1 - PHPK|H (1- Susceptibility * Vulnerability)
• Increased likelihood for mission success

Analysis, threat matrix
Analysis of common threat characteristics• Highly transportable• Designed to fly…• On-board propellant• Similar physical attributes• Similar kinetic energy
SAAB PROPRIETARY INFORMATION
Analysis, proliferated threats
SAAB PROPRIETARY INFORMATION
Result of analysis
A CMDS is needed to address the plethora of current, emerging and future threatsUse knowledge of common threat characteristics
No such system exists today for flying platforms
