The objective
Complete the mission objectives
Achieve 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

SAAB PROPRIETARY INFORMATION
The problem in a nutshell
A plethora of existing and emerging threats
Limited knowledge of installed seeker/guidance technology
Unguided threats do not respond to decoys
Proliferation of developed weapons
Development trend of consumer electronics

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 threats
Use knowledge of common threat characteristics
No such system exists today for flying platforms
SAAB PROPRIETARY INFORMATION
TIPS, the idea
To physically counter incoming threats regardless of
guidance technology, if at all present....
