1. AS A RESULT OF THE SAM ACTION ENCOUNTERED DURING MISSION
BX6734, I BELIEVE A COMPLETE EXAMINATION AND ANALYSIS OF OUR EWS
CAPABILITY AND INTELLIGENCE ESTIMATES ARE DUE. IN REVIEWING OUR
INTELLIGENCE BRIEFINGS TO THE DRIVERS IT IS OBVIOUS WE HAVE EITHER
UNDERESTIMATED THE CAPABILITY OF THE SAMS USED IN NORTH VIETNAM
OP THEY ARE USING A NEW WEAPON SYSTEM. STATEMENT THAT
OF THE APPROXIMATELY SIX SAMS OBSERVED, ALL GUIDED VERY ACCURATELY,
ALL EMITTED CONTRAILS THROUGH HIS ALTITUDE (ESTIMATED 90,000 FEET)
LEVELED OFF AND DOVE BACK DOWN LEVELING AGAIN IN A STERN CHASE STILL
EMITTING CONTRAILS. HE OBSERVED AT LEAST THREE DETONATING ON AZIMUTH
AND ELEVATION IN A CLOSE TRAIN POSITION. DURING THIS PERIOD EWS
LIGHTS WERE INDICATING NORMAL WITH MAD -MOTH AND LAUNCH LIGHTS `SON-.
ALTITUDE WAS APPROXIMATELY 53,500 AT 3.15/3.2 MACH. THE MISSILE

ESTIMATED AND CONNING AS IT WENT OUT OF SIGHT ABOVE. A LATER LOOK IN
REAP VIEW MIRROW SHOWED ALL CONTRAILS FLYING THE SAME PATTERN, THEPE-
FORE, ASSUME THIS ONE ALSO PUSHED OVER TO DIVE ON HIM. IF EXAMINATION
OF THE HOLE AND FRAGMENT FOUND I N THE A IRCRA-FT SHOWS IT CAME FROM A
MISSILE, WHICH I STRONGLY SUSPECT V THIS SERVES, AS PROOF OF ACCURACY.
IT APPEARS TO US AS THOUGH THIS MAY .HAVE BEEN A FLOCK OF THE GRIFFON
TYPE SAM (ZUP-D) PERHAPS WITH TERMINAL GUIDANCE WHICH MAY HAVE
BEEN IF e
2. BELIEVE WE SHOULD ALSO EXAMINE AND CHANGE OUR OPERATIONAL
TACTICS IN AS MANY AREAS AS POSSIBLE. AS A START IN THE TACTICS AREA
I SUGGEST THE FOLLOWING FOR YOUR CONSIDERATION:
A. SINGLE PASS OVER THE TARGET AREA CHANGING THE PENETRATION
ROUTING AS MUCH AS POSSIBLE FROM THAT PREVIOUSLY USED.
B. PLANNING THE FLIGHT FOR MAXIMUM ALTITUDE AND SPEED OVER
THE KNOWN SAM DEFENSE AREAS.

POSSIBLE
CHANGE TIME OF OVERFLIGHT OUT OF THE ROUTINE 020OZ AREA.
COORDINATE OUF OVERFLIGHT TO COINCIDE WITH TACTICAL
OPERATIONS IN THE SAM AREAS. THIS TU INCLUDE BOTH AF AND
ELIMINATE OR REDUCE NOTIFICATION PRESENTLY PROVIDED TO
ORGANIZATIONS THROUGH 313ADIV IAW THE JCS DOCUMENT.
PROGRAM ROUTE SO AS TO PPOVIDE OBLIQUE PHOTOGRAPHY OF
AREAS TO AVOID D IPECT OVERFLIGHT OF KNOWN HEAVY SAM AREAS.
CONSIDERATION` SHOULD BE GIVEN TO USING PKG FOUR IN THIS TYPE
OPFRAT ION.
G. CHANGE ROUTING TO TARGET AREA AS REQUIRED TO PROVIDE A

CONSIDERABLE CHANGE IN TIME ENPOUTE FROM TAKE OFF TO OVERFLIGHT.
H. USE OTHER REFUELING AREAS TO POSSIBLY PRECLUDE ANY TIPOFF
OF OUF ROUTE OF FLIGHT .
I. STAGE TANKERS TO ELIMINATE POSSIBLE CONNECTIONS OF LOCALLY
BASED TANKER ACTIVITY WITH OUF AIRCRAFT OPERATIONS.
J. PROGRAM ROUTE FOP A TURN OVER THE SAM DEFENSE AREAS.
AGAIN PACKAGE FOUR COULD BE USED. AND PROGRAMMED FOP OBLIQUE OPERATION
IN THIS TURN TO OBTAIN VERTICAL OR NEAR VERTICAL PHOTOGRAPHY.
K. TAKE OFF KADENA MAX GROSS WITHOUT TOPOFF AND PROCEED
DIRECT TO AIR STEEL BRIDGE.
L. STAGE ARTICLE OUT OF TAKHLI WITH WITHDRAWAL AIR OFF
CLAPK, P.I.
3. SUGGESTION'S IN THE EWS AREA APE t
A. ALTERNATE USING MAD MOTH AND BIG BLAST.
B. STUDY ANTENNA PATTERNS AND EFFECT OF EIS SYSTEM IN TURNS
(THHIS INCLUDES BOTH DF AND JAMMING SYSTEMS).
C. EXAMINE POSSIBILITY OF INSTALLING CHAFF SYSTEMS IN THE
AIRCRAFT .
D. STUDY EFECTS OF EWS SYSTEMS ONCE SAM PROCEEDS TO A
POSITION ABOVE THE AIRCRAFT.
E. EXAMINE POSSIBILITY OF INSTALLING IR MISSILE DEFENSIVE
SYSTEMS IN THE AIRCRAFT.
4. A S STATED ONCE BEFORE, IT BECOMES A SIMPLE TIMING PROBLEM TO
CALCULATE A SECOND PENETRATION TIME USING TACTICS SUCH AS WE HAVE BEEN
USING, IT APPEARS THE SECOND PASS IS THE MOST VULNERABLE. WE MUST
GIVE OUR OPPONENTS THE CREDIT FOP BEING ABLE TO MAKE THESE CALCULATIONS
AND/OR CHANGE THEIR TACTICS TO COUNTER THIS AIRCRAFT. A DETERMINED
EFFORT ON THEIR PART COULD VERY LIKELY GET US UNLESS WE KEEP AHEAD

AND KEEP THEM GUESSING. THEIP EFFORT AGAINST BX6734 WAS TOO CLOSE
FOR COMFORT.
5. I'M SURE YOU FOLKS APE ALSO THINKING HARD ABOUT THIS PROBLEM
AS WE WOULD ALL LIKE TO SEE A GOOD COUNTER TO THE THREAT. THE ABOVE IS
SUBMITTED BECAUSE I BELIEVE THE OLD ADAGE "TWO HEADS APE BETTEP THAN
ONE" APPLIES. KEEP US POSTED ON ANY UPDATED INFO YOU RECEIVE ON SAM
