4.7.44 Launcher tubes boresight test. To determine conformance to 3.6.14.3, the boresight
elevation and azimuth angles of the launch tubes relative to the optical line of sight shall be
tested using ITV peculiar support equipment, boresight target board, boresight test aperture and
the boresight adapter tool. The test procedures listed in 4.7.45.1, shall be followed to assure that
these angles are within specified tolerances.
4.7.45 Launcher tubes boresight retention test. To determine conformance to 3.6.14.3, the
boresight angles of the launch tubes shall be tested using ITV peculiar support equipment,
boresight target board, test aperture and adapter tool. To assure that boresight angles are within
specified tolerances and procedure, the test procedures specified in 4.7.45.1 shall be followed for
launcher elevation angles near maximum depression and elevation, and mid-range.
4.7.45.1 Launch tube boresight test procedure.
a. Apply power to the turret and erect launcher.
b. Install and test daysight/tracker, as applicable.
c. Insert drawing 12277611 boresight adapter and remote arming device alignment tool
into right or left launcher in the same way a missile is loaded. Position RAD in the
"ARMED" state. Insert shank of telescope boresight into socket of adapter with light
finger pressure.
d. Open cargo hatch cover.
e. Set SELF TEST switch on Missile Guidance Set (MGS) to position 7 and depress
OPERATE switch. Adjust azimuth and elevation knobs on daysight/tracker, and for
mid-scale reading on MGS ELEVATION and AZIMUTH self test meters.
f. Close cargo hatch cover.
g. Set up drawing 12277600 target board at a distance of 100 feet 6 inches from the
turret elevation axis.
h. Fit drawing 12277608 pinhole cover over daysight/tracker objective lens.
i. Set turret power switch on control panel to ON.
j. Set 3X, l3X, WFOV switch on turret hand controller to 13X.
k. Sight through turret eyepiece and operate turret to position sight on target.
l. Rotate the target board and center the vertical strip about the daysight vertical reticle.
Secure the target board in this position.
m. Operate the turret to position daysight/tracker reticle on target board reticle.
n. Sight through the boresight telescope and verify that the crosshair reticle of the
boresight is within the launch tube boresight launcher field check window on the
target board.
o. Boresight the other launch tube in the same way.
