CALIBRATION TEST PREPARATIONS
SHAGAN RIVER TEST AREA,
Usmr
NPIC/IEG (5/82)
3 MAY 1982
1. (S/D) SIGNIFICANCE: THESE CALIBRATION TESTS ARE PRECURSORS TO
ICBM SILO VULNERABILITY TESTS WHICH ARE PROBABLY SCHEDULED FOR
THIS SUMMER AT SHAGAN RIVER.
2. (S/D) REMARKS: PREPARATIONS FOR BLAST AND OVERPRESSURE
CALIBRATION TESTS ARE UNDERWAY AT SILOS 16 AND 132. SILO 16, AT
LOCATION 122, WAS THE CALIBRATION TEST SILO FOR THE 1981 SILO
VULNERABILITY TESTS AT AREA 89. THIS WILL BE THE FIRST TIME THE
SOVIETS HAVE USED A CALIBRATION SILO TWICE. SILO 132 (LOCATION
132) IS A NEW CALIBRATION SILO BEING BUILT FOR 1982 VULNERABILITY
TESTING AT AREA 89. THE TWO CALIBRATION SILOS ARE ADJACENT TO
EACH OTHER AND TWO MILES WEST OF AREA 89. A THIRD CALIBRATION
TEST, OF A SMALL HIGH EXPLOSIVE SIMULATION TECHNIQUE (HEST)
STRUCTURE, IS BEING PREPARED IMMEDIATELY SOUTH OF SILO 16, NEXT
TO THE REMAINS OF THE 1981 SMALL HEST STRUCTURE TEST.
(S/D) THREE TYPES OF HIGH EXPLOSIVE (HE) SIMULATORS WILL BE USED
AT SILOS 16 AND 132. ARCH-ROOFED HEST STRUCTURES, ROW BERM
LOADED EXPLOSIVE SIMULATION TECHNIQUE (BLEST) BEDS, AND DIRECT
INDUCED HIGH EXPLOSIVE SIMULATION TECHNIQUE (DI-HEST) ARRAYS WILL
BE USED AT EACH SILO. THE HEST COMPONENTS AND TUBULAR EXPLOSIVES
FOR THE BLEST SUGGEST THAT THE HEST AND BLEST SIMULATORS WILL BE
LIKE THOSE USED LAST YEAR. HOWEVER, THE CONFIGURATION OF THE
SHAFTS FOR THE DI-HEST ARRAYS IS NEW.
(S/D) IN 1981, THE DI-HEST ARRAY TESTED AT SILO 16 AND LATER
USED AT SILOS 11 AND 13 IN AREA 89, CONSISTED OF A LINE OF THREE
1-METER-DIAMETER SHAFTS SPACED 25 METERS APART. THE LINE OF
SHAFTS WAS PERPENDICULAR TO A 60-METER LINE BETWEEN THE CENTER
SHAFT AND THE SILO. THE NEW DI-HEST ARRAYS AT SILOS 16 AND 132
HAVE FIVE SHAFTS; THREE IN THE SAME :POSITION AS THE 1981 DI-HEST
ARRAYS PLUS TWO ADDITIONAL SHAFTS ON A LINE PARALLEL TO THE LINE
OF THREE SHAFTS BUT 20 METERS BEHIND THEM. THE TWO ADDITIONAL
SHAFTS ARE ALSO APPROXIMATELY 25 METERS APART AND ALL FIVE FORM A
TRAPEZOIDAL PATTERN.

lytical work. Their use should be restricted to the particular briefing board(s) they were prepared for
and must be considered valid only for the reporting period as indicated by the date of issue.

3 MAY 1982
(S/D) WHILE THE PATTERN AND SPACING OF THE TRAPEZOIDAL DI-HEST
ARRAYS ARE THE SAME AT SILOS 16 AND 132, THE SIZE OF THE SHAFTS
IN THE ARRAYS APPEARS TO BE DIFFERENT. THE SILO 16 DI-HEST
SHAFTS APPEAR TO BE MORE THAN TWICE THE DIAMETER OF THE SILO 132
DI-HEST SHAFTS. ALSO, THE TWO SHAFTS IN THE SECOND LINE OF THE
DI-HEST AT SILO 16 APPEAR TO BE SMALLER THAN THE THREE IN THE
FIRST LINE. THESE DIFFERENCES-IN SHAFT DIAMETER SUGGEST THAT THE
DESIGN OF THE TRAPEZOIDAL DI-HEST ARRAY HAS NOT BEEN FINALIZED,
AND THAT ONLY THE ARRAY WHICH PROVIDES THE MOST DESIRABLE RESULTS
WILL BE USED LATER THIS YEAR TO TEST SILOS 10 AND 12 IN AREA
89. 25X1
