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

Actions
Preventive / Tactical• Arms control• Port and border security
Tactics • Flying tactics and operating procedures • Speed / altitude• Situational awareness• ConOps
Technical• Hardening of structure• Ruggedized airframe• Blast protection• Signature reduction• System redundancy• Countermeasures
Survivability = 1- (Susceptibility * Vulnerability)
Layers of protection
SAAB PROPRIETARY INFORMATION
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
SAAB PROPRIETARY INFORMATION
TIPS, the idea
To physically counter incoming threats regardless of guidance technology, if at all present....
SAAB PROPRIETARY INFORMATION
Threat characteristics
Counter threats with the following characteristics• Portable by a single person• Speed: 84 – 600 m/s• Mass: 1,9 – 10,8 kg• Body/warhead diameter: 4 – 10,5 cm• Altitude: 0 – 3500 m• Range to shooter: xx – 5000 m

TIPS, one system – all threats
System functions• Detect
• Radar• Short range• High resolution• 360° coverage• Installed on the platform
• Launch• Intercept• Defeat
SAAB PROPRIETARY INFORMATION
TIPS, one system – all threats
System functions• Detect• Launch
• A directional launcher• Azimuth and elevation• Directed towards the incoming threat• Launch of counter-projectile• Sector inhibit function
• Intercept• Defeat

TIPS, one system – all threats
System functions• Detect• Launch• Intercept• Defeat
• Defeat mechanism• The threat defeat mechanism is activated at a suitable
distance from the incoming threat• Remote or proximity activated• Preferably non-explosive
