SCOPE.
a. This manu+mntains a descriptionof the 4.5” Rocket .Launchers MlO, M14, and M~l5. In addition, it contains technical information required for the identification, use, and care of the laun6her and ammunition. This manual does not cover electrical wirine or switches in the plane, or the firing selector mechanism. The pr&rement and installation of such accessories is the responsibility of AAF.
2.
REPORTS.
a. Field Report of Accidents. When an accident involving ammunition occurs during practice, the incident will be reported as prescribed in AR 750-10 by the Ordnance officer under whose supervision the ammunition is maintained or issued. Where practicable,, reports covering malfunctions of amrinmition in combat’ will be made ,to the Chief of ?rdnance, giving the type of malfunction, type of ammunition, the lot number of the complete rounds or separateloading components, and condition unde‘r which fired. . b. Unsatisfactory Equapment Rrsport. Suggestions for improvement in design, maintenance, safety, and efficiency of operation ~prompted by chronic failure or m ‘ alfunction of the weapon, spare, parts, or equipment bhould. be reported on WDAGO Form No. 468, Unsatisfactory Equipment Report, with all pertinent informatibn necessary to initiate corrective action. The report should be forwarded to the Office of Chief of Ordnance,, Field Servicti Maintenance Division, through command channels in accordance with instruction number 7 o‘ n the form. Such suggestions are encciuraged in order that other organizations may benefit. 3.

ROCKET LAUNCHER MIO.
a. The Launcher Ml0 con&ts of a cluster of three lo-foot tubes of N-inch plastic which e?e attached by steel strapping to a slide her, end bv two mounts to the under. side of the wine of the olane (fins. 1 to i). The straps .are tightened *round the i&e by t‘ urnbicie screws tightened end wired in ,place.
b. The front mount consists of a T-shaped hanger attached to the plane, a front mount strep on which are mbunted two hooks, and a deflector ,assembly (fig. 4). TWO set screws are provided to fasten the strep in position on ,the slide bar. The deflector assembly con: sists bf two ,18-inch erms attached to a deflector strep end bearing on the front hanger. When the launcher is dropped, the arms serve to direct the “se of the ,launchir downward es air pressure pushes the tubes to the rear. e. The rear mount (figs. 5 end 6) consists of a hanger containing the release m+chanism end a socket for electrical comiections, end a V-shaped sway brace. The rear mount strap has a suspension lug end two L-shaped detainer supports. When the launcher is dropped, the detainer supports engage the erms of the sway brace end prevent the’ rear end dropping until the deflector pushes the front end downward. The rear mount strep is positioned on the slide bar by e clevis pin.
d. In addition to the f‘ ront end rear mount straps, there is B tenter strap riveted to the slide bar end tightened to proper tension by the manufacturer. One in&ahead of the rear end there is a deflector strap to. protect the release end contact mechanisms from flying links end fired cases from the plane’s guns. 5. /

M ‘ inor flakes or blisters oil the inside of the tubes &ill not affect operation of the launcher. (2) Check the center strep to see that it is tight and safety-wired.’ Do not tamper with this strep unless it has not been safety-wired beceuse it has been properly adjusted for tension et the factor~.,,Cha~ges

(6) Fasten the rear mount strap by inserting the clevis pin into the proper ,hole in the slide bar and secure it with the cotter pin. Tighten the turnbuckle sctew in the rear mount strap. Safety-wire the screw. (7) Lift the launcher to the wing, fit the rear mount strap into the rear mount, and flock it there by using the release lever once (fig. 7). The detainer supports are automati+ly positioned above the swSy braces when the rear strap is attached to the mount. 4 leaf spring is &ached to the top of the rear strap. It is necessary to compress this spring SO that it will lie between the top of the rear strap and the bottom of ,the rear’m ount. 7
TM 9.395 7.8 4.5” AIRCRAFT ROCKET MATERIEL Raise the front of the lauqcher and ,position the &oqt mount (8) strap so that the hooks on the front strap fit snugly (but are not jammed) against the front mount. Be sure that the hooks are parallel to the axis of the tubes. Tighten the set screws on both sides of the strap until they penetrate into the slide bar, to prevent the strap from slipping. Be sure that the conical points of the set screws penetrate the slide bar: T‘ ie with safety wire. Tighten the turnbuckle screw to keep the strap from slipping axid secure it with safety wire. (9) Fasten the sway brace screws at the rear post until they press lightly a&nst the cluster. Slide the defl+tor arm strap rearward until the hooks on‘t he ( 10) deflector arm ,fit snugly against the front of the front mbunt without Be sure that the hooks are in a position to slide freely into jamming. the front post as the front strap leaves it.’ Tighten turnbuckle screw and secure with a safety wire. The shield strap is in its proper position when the launcher (11) is received. If it is necessa~ to mwe it during installations, unlatch the buckle at the bottom of t‘ he strap. Be sure to set the shield strap about 1 inch forward of the, contact arms. Latch the buckle and safety-wire it to prevent a&dental opening. Examine the straps to be sure that all the screws have been (12) Nqscrew should be so tightened correctly tightened and safety-wired. that all of it enters the trunnion blocks or damages the launcher. Tension for the mount straps is controlled by a stop sleeve mounted on the trunnion screw. The proper tension 1s obtained when trunnion screw has been tightened until lock nut comes in contact with trimnion.
