The ship as a weapon system
Combat suite of a frigate / patrol vessel
Mission and Roles (Tasks)
Peacetime Employment:
maritime surveillance
fishery patrol
protection of offshore resources
law enforcement tasks
support tasks: disaster relief, medical evacuation, search and rescue
Time of Tension:
reconnaissance and surveillance patrol
investigation and interdiction of surface contacts
escort and protection of coastal shipping
limited protection of offshore resources and infrastructure
seaward defence of ports
support of land force operations
Threats
medium-sized surface combatants:
OPVs, corvettes, frigates
speed boats armed with small-calibre guns or missiles
land-based attack aircraft armed with small-calibre guns or missile
land-based defence systems:
medium-calibre guns or small-calibre missiles
Selection of sensors and weapons
based on: area of operations, tasks, threats
define a number of reference scenarios
select a proper simulaton device for functional chains
evaluate efficiency of weapons and sensor-weapon combinations under consideration
select sensor-weapon combination with respect to
efficiency in the different reference scenarios defined
number of anticipated sensor-weapon combinations / functional chains
avaible funding
Engagement Sequence I
Check of functional chain feasibility
determine intended weapon/target intercept range
determine necessary weapon release time
add weapon preparation time from target indication until ready to fire
read out the necessary target acquisition range of the weapon guidance sensor
add time for command team decision making and tracker designation/weapon calculation
read out necessary surveillance sensor’s confirmed track range
add time from first detection until track established
read out necessary surveillance sensor’s detection range
Engagement Sequence II
Physical operational conditions of surveillance radars/sonars
Technical operational conditions of fire control radars
TV and IR sensors
IR sensors
Advantages and disadvantages of fire control radar
Advantages of fire control radar:
long detection and tracking range
automatic target acquisition
low weather dependency
Disadvantages of fire control radar:
disclosure of presence due to transmitted energy
multipath effect when tracking low-flying targets
glint effect in case of vast targets
more expensive than EO director
Advantages and Disadvantages of EO director
Advantages of EO director:
most of the time passive operation (laser ranger only used for short time)
optical target identification possible
less multipath effect when tracking low-flying targets
Disadvantages of EO director:
shorter detection and tracking range
target acquisition requires operator support
strong dependence on weather conditions
classification of functional chains
primary functional chains
provide maximum accuracy and the largest operational range
scondary functional chains
provide capabilities similar to those of primary chains but have limitations regarding operational sectors and/or accuracy and/or reaction time
emergency functional chains (casualty)
provide limited weapon capabilities with considerably reduced accuracy and/or reaction time
