Surface To Air Weapo Systems Flashcards
CYCLIC RATE OF FIRE (ROF)
MAXIMUM THEORETICAL ROUNDS PER MINUTE (RPM) THAT THE SYSTEM IS CPABLE OF FIRING.
Caliber
Bore diameter of the gun and is normally measured in millimeters (mm).
PRACTICAL RATE OF FIRE
MAXIMUM ROF THAT TAKES INTO ACCOUNT THE SYSTEM’S LIMITATIONS OF ADA.
TOWED ADA
ADA PIECE THAT REQUIRES ANOTHER VEHICLE TO MOVE THE ADA SYSTEM.
***CAN BE IDENTIFIED IN IMAGERY BY THE “V” SHAPE IN FRON OF THE ADA PIECE***
SELF-PROPELLED ADA
ADA PIECE THAT IS TRACKED OR WHEELED AND CN MOVE WITHOUT HE HELP OF ANOTHER VEHICLE.
SMALL ARMS/AUTOMATIC WEAPONS(SA/AW)
INCLUDES:
- SMALL ARMS AND MACHINE GUNS BELOW 12.7MM
- SA/AW CHARACTERIZED BY HIGH CYCLIC ROF
- THIN TRACER PATHS
- NO SELF DESTRUCT (SD) ELEMENT
ARMOR PIERCING (AP) ROUNDS
- DESIGNED TO PENETRATE ARMOURED VEHICLES USING PRIMARILY KINETIC ENERGY
FRAGMENTATION (FRAG) ROUNDS
- BURSTING CHARGE THAT SHATTERS THE SHELL INTO HUNDREDS OF STEEL SHARDS
- FRAG ROUNDS PRODUCE A LARGE UNSHAPED FRAGMENTARY BLAST
- USUALLY TIME OR ALTITUDE FUZED
INCENDIARY (I) ROUNDS
- HAVE ELEMENTS ADDED THAT BURN INSTENSELY AFTER ROUND DETONATION
- CAN CAUSE FUEL SUPPLY IGNITION OR BURN CRITICAL COMPONENTS
- ALSO ADDED TO OTHER AMMUNITION TYPES
***EXAMPLE: AN AP OR HE ROUND COULD ALSO HAVE INCENDIARY EFFECTS MAKING THEM API OR HEI RESPECTIVELY***
TRACER (T) ROUNDS
- HAS AN ELEMENT THAT BURNS BRIGHTLY TO ALLOW THE GUNNER TO TRACE THE PATH OF THE PROJECTILE WHEN FIRING IN LOW-LIGHT CONDITIONS
- IF TRACER IMPACTS PRIOR TO TRACER BURNOUT, IT MAY CAUSE INCENDIARY EFFECTS
AIMED FIRE
- PREFERRED METHOD
- MOST CONTROLLED TYPE OF FIRE
- ADA WEAPONS ARE AIMED SPECIFICALLY AT THE AIRCRAFT
BARRAGE FIRE
- LEAST CONTROLLED TYPE OF ADA FIRE
- LAYS A CLOUD OF PROJECTILES AT VARIOUS ALTITUDES ACROSS THE PROBABLE PATH OF THE ENEMY AIRCRAFT
- USED WHEN THE FC SYSTEM CANNOT ACCURATELY TRACK THE TARGET
CURTIN FIRE
- DIRECTED AT A FIXED POINT IN FROT OF THE TARGET ALONG THE TARGET’S COURSE UNTIL THE TARGET PASSES THROUGH THE CONE OF FIRE
- MOST EFFECTIVE MEANS OF EMPLOYING SA/AW
- A TECHNIQUE MOSTLY USED BY INSURGENTS
AIR DEFENSE ARTILLERY RANGES
- ACTUAL THREAT RANGE DEPENDS ON MANY FACTORS INCLUDING
- TYPES OF FIRE
- SHELL TYPE
- FUZE TYPE
- ENVIRONMENT
- TARGET TYPE
- TARGET FLIGHT PROFILE
- EMPLOYMENT DOCTRINE
- NO SINGLE RANGE VALUE CAN ADEQUATLEY PREDICT THE “SAFE” DISTANCE OR ALTITUDE FOR AIRCREW
- AS A RESULT ADA HAVE MUTIPLE RANGES ASSOCIATED WITH IT
- ENVIRONMENTAL CONDITIONS SUCH AS AIR DENSITY CAN AFFECT THE RANGE OF A ROUND
TACTICAL RANGE
- SLANT RANGE AT WHICH A NON-MANEUVERING FIGHTER AIRCRAFT CAN EXPECT TO RECEIVE FIRE FROM A PARTICULAR GUN WITH A HIGH PROBABILITY OF HIT (Ph)
- THIS WHEN ONE CN EXPECT TO RECEIVE AIMED FIRE
MAXIMUM VERTICAL RANGE
- GREATEST RANGE A ROUND CAN TRAVEL IN ALTITUDE (AT SEA LEVEL) ASSUMING IT IS FIRED AT MAXIMUM ELEVATION AND NO FUZE OR SD FUNCTIONS
- RANGE IS NORMALLY ACHIEVED BY ARMOR-PIERCONG (AP) ROUNDS ONLY
- PROVIDES A TRUER THREAT PICTURE FOR BARRAGE AND CURTIN FIRE
OPEN FIRE RANGE
- THE DISTANCE A GUNNER BEGINS TO FIRE SO THE ROUNDS IMPACT THE TARGET AT THE TACTICAL RANGE
MISSILE GUIDANCE TYPES
- BASIC GUIDANCE CONCEPTS
- HOMING GUIDANCE
- COMMAND GUIDANCE
HOMING GUIDANCE
- USED BY SYSTEMS WITH SEEKERS THAT CAN SENSE A TARGET AND THEN GUIDE TO THE TARGETBY SENDING COMMANDS TO THE MISSILE INTERCEPT TARGET
- USED FOR ENTIRE FLIGHT OR TEMINAL PHASE
HOMING GUIDANCE
- DIVIDED INTO THREE GROUPS
- ACTIVE
- SEMI-ACTIVE
- PASSIVE
COMMAND GUIDANCE
- TYPICALLY MISSILES WITHOUT SEEKERS
- REQURE COMMANDS FROM OUTSIDE SOURCES SUCH AS GROUND TARGET TRACKING RADAR (TTR)
MISSILE GUIDANCE LAWS
- IS THE RELATIONSHIP BETWEEN THE MISSILE AND THE TARGET USED TO GENERATE MISSILE STEERING COMMANDS
- ARE TEH WAY THE SYSTEM COMUNICATES STEERING COMMANDS TO THE MISSILES BASED ON THE SYSTEM’S GUIDANCE LAW
MISSILE GUIDANCE LAWS
- DIVIDED INTO THREE CATEGORIES
- PROPORTIONAL NAVIGATION (PN) GUIDANCE LAW
- COMMAND-TO-LINE-OF-SIGHT (CLOS) OR 3-POINT GUIDANCE LAW
- LEAD ANGLE/HALF-RECTIFIED GUIDANCE LAW
PROPORTIONAL NAVIGATION GUIDANCE LAW
- PRODUCES THE MOST EFFICIENT TRAJECTORY OF ALL THE GUIDANCE LAWS
- ALLOWING LOWER MISS DISTANCES
- IMPROVED MISSILE KINEMATIC RANGE
COMMAND-TO-LINE-OF-SIGHT-GUIDANCE-LAW
- ALSO CALLED THREE POINT
- ISSILE IS FIRED STRAIGHT AT THE TARGET AND STEERED TO KEEP IT ON A DIRECT LINE BETWEEN THE TER AND THE TARGET
CLOS
- DIVIDED INTO THREE CATGORIES
- MANUAL CLOS
- SEMIAUTOMATIC CLOS
- AUTOMATIC CLOS
MANUAL CLOS
- SYSTEM REQUIRES AN OPERATOR TO VISUALLY ACQUIRES AND TRACK THE TARGET AND USE A JOYSTICK TO FLY THE MISSILE TO IMPACT THE TARGET
SEMIAUTOMATIC CLOS
- SYSTEM REQUIRES AN OPERATOR TO VISUALLY ACQUIRE AND MAINTAIN TRACK ON TARGET WITH AN OPTICAL DEVICE
- BUT A SEPERATE AUTOMATIC TRACKING DEVICE TRACKS THE MISSILE AND AUTOMATICALLY UPLINKS GUIDANCE COMMANDS TO THE MISSILE VIA RF SIGNAL
AUTOMATIC CLOS
- SYSTEMS AUTOMATICALLY TRACK THE MISSILE ON TARGET
- ONCE TARGET HAS BEEN LOCKED ON OPERATOR INPUTS ARE NO LONGER REQUIRED
LEAD ANGLE GUIDANCE LAW
- FOUND ON OLDER TRACK-WHILE-SCAN (TWS) COMMAND-GUIDED SYSTEMS
LEAD ANGLE GUIDANCE LAW
- STEERS THE MISSILE TO A CONSTANT ANGLE AHEAD OF WHERE THE TARGET IS CURRENLTY LOCATED
LEAD ANGLE GUIDANCE LAW
- HALF-RECTIFIED GUIDANCE LAW STEERS THE MISSILE TO A POINT HALFWAY BETWEEN THE PREDICTED INTERCEPT POINT TO THE CURRENT TTR-TO-TARGET LINE-OF-SIGHT
LEAD ANGLE GUIDANCE LAW
- SAMS EMPLOYING EITHER LEAD ANGLE OR HALF-RECTIFIED GUIDANCE LAW WILL APPEAR TO DRIFT SLIGHTLY AFT OF THE CANOPY (OF A NON-MANEUVERING TARGET)
MISSILE FLIGHT PROFILE
- IS THE TRAJECTORY THE MISSILE TAKES TO GET TO THE TARGET
SAM ENGAGEMENT SEQUENCE
- 7 STEPS TO THE SAM ENGAGEMENT SEQUENCE
- SEARCH
- DETECTION
- TRACK
- FIRECONTROL AND LAUNCH
- MISSILE CAPTURE
- MISSILE FUSING AND DETONATION
- KILL ASSESSMENT
- ALL SAM SYSTEMS DESPITE GUIDANCE TYPE, GUIDANCE LAW, OR FLIGHT PROFILE, HAVE THE SAM GENERAL STEPS TO COMPLETE TO SUCCESSFULLY INTERCEPT A TARGET
SEARCH
- IAR DEFENSE SYSTEMS MUST INPSECT A VOLUME OF SPACE INORDER TO LOCATE AIRCRAFT
- THIS CAN BE PERFOEMD BY A RADR LOCATED FAR AWAY FROM THE FIRE UNIT SINCE TAREGET INFORMATION CAN BE PASSED VIA DATA LINK OR BY A SEARCH RADAR LOCATED NEXT TO OR EVEN ON THE SAME VEHICLE AS THE TTR
DETECTION
- WHILE SEARCHING A TARGET IS SCANNED BY THE ANTENNA BEAM AND SUFFICENT ENERGY IS REFLECTED FROM THE TARGET TO THE RADAR
- DETECTION CAPABILITY IS DEPENDENT OF FACTORS SUCH AS THE RADAR TRANSMITTER POWER, ANTENNA GAIN, RECEIVER CHARACTERISTICS, AND TARGET’S RADAR CROSS SECTION (RCS)
TRACKING
- WHILE TRACKING THE TARGET THE SAM SYSTEM WILL COMPLETE THREE DIFFERENT TRACKING PHASES
- NON-PRECISION TRACKING
- DESIGNATION AND TARGET RADAR ACQUISITION
- PRECISION TRACKING
NON-PRECISION TRACKING
- ONCE TARGET IS DECLARED CHANGE IN POSITIONS FROM SCAN TO SCAN IS MEASURED AND TRACKED AND AN ESTIMATE OF THE TARGET’S POSITION BETWEEN SCANS IS MADE
DESIGNATION AND TARGET RADAR ACQUISITION
- THIS IS WHEN TEHE TTR OR TER REEIVES THE AZIMUTH AND ELEVATION ANGLES OF THE TARGET FROM SEARCH RADAR AND IS SLEWED TO POINT AT THE TARGET
- TTR PERFORMS A LIMITED SEARCH AND DETECTS AND STARTS TO TRACK THE TARGET
- NORMALLY ACCOMPLISHED BY ON-BOARD ACQUISITION RADARS IN THIS PHASE
PRECISION TRACKING
- AACURATE AND FREQUENT MEASUREMENTS OF THE TARGETS POSITION ARE MADE
FIRE CONTROL AND LAUNCH
- ONCE ACCURATE TARGET INFORMATION IS KNOWN THE FINAL DECISION TO LAUNCH AND AT WHAT RANGE IS MADE
- DECISION IS BASED ON SHOT DOCTRINE, SYSTEM LIMITATIONS, TARGET CHARACTERISITICS, AND OTHER VARIABLES
MISSILE CAPTURE
- ALLOWS THE TTR TO TRACK THE MISSILE AS IT FLIES TO THE TARGET
- SINCE MISSILE GUIDANCE CANNOT START UNTIL MISSILE TRACK BEGINS AND ACCURATE INTERCEPTS CANNOT OCCUR UNTIL SOMETIME AFTER THE GUIDANCE INITIATES, MISSILE CAPTURE TIME DIRECTLY AFFECTS THE MINIMUM EFFECTIVE RANGE OF THE SYSTEM
MISSILE FUZING AND DETONATION
- MOST RF SAMS ARE EQUIPPED WITH A RF OR OPTICAL PROXIMITY FUZE
- PROXIMITY FUZE IS DESIGNED TO DETECT WHEN THE MISSILE IS CLOSE ENOUGH TO THE TARGET TO DETONATE THE WARHEAD AND CAN BE ACTIVE OR PASSIVE
KILL ASSESSMENT
- FINAL PHASE OEMF SAM ENGAGEMENT SEQUENCE
- SAM CREWS WILL DO IN ONE OF TWO WAYS:
- CHANGES TO THE TARGET’S TRAJECTORY AFTER DETONATION
- INPUT FROM EXTERNAL SOURCESE
- THE CYCLE MAY BEGIN AGAIN IF THE TARGET IS NOT DESTROYED
KINEMATIC RANGE
- POTENTIAL RANGE AT WHICH A GUIDED MISSILE COULD INTERCEPT A TARGET DISREGARDING ALL DOCTRINAL AND SENSOR LIMITS
MAXIMUM INTERCEPT ALTITUDE
- A MISSILE CAN INTERCEPT A TARGET
PREEMPTIVE MANEUVER
- AIRCREWS EXECUTE THIS MANEUVER PRIOR TO ACTUALLY DSETECTING A THREAT SYSTEM
- DEISNGED TO AVOID INDIVIDUAL THREATS
- DENY EARLY ACQUISITON
- COMPLICATE EARLY INDENTIFICATION AND TRACKING
- PROVIDE THE AIRCREW WITH A POSITIONAL ADVANTAGE IF AN ENGAGEMENT IS INITIAITED
REACTIVE MANEUVER
- IN REPSONSE TO THE INITIATION OF A SPECIFIC ENGAGMENT SEQUENCE
- USUALLY EXPLPOIT THE TRACKING, KINEMATIC INTERCEPT, GUIDANCE AND FUSING PORTIONS OF THE ENGAGEMENT SEQUENCE
TOD

- AOR SPECIFIC BRIEFING INCLUDES
- THE CAPABILITES ARE SPECIFIC FOR ALL KNOWN/SUSPECTED VARIANTS OF THE SYSTEM IN THE AOR
- EMPLOYMENT DOCTRINE AND TACTICS ARE COUNTRY SPECIFIC
- RATHER THAN PROLIFERATION YOU ARFE CONCERNED WITH HOW MANY SYSTEMS ARE IN THE AOR AND WHERE THEY ARE LOCATED
