MC-1C Steerable Troop Parachute Assembly

    All MC1-1C Canopy Assemblies are manufactured using the latest revision of material listed in Technical Data and new U.S. Army material color Camouflage Green #483. All MC1-1C Canopy Assemblies are manufactured in strict accordance with Personnel Parachute U.S. Military Specifications MIL-DTL-6645, MIL-DTL-7567 and MIL-STD-849, latest revisions. All MC1-1C Canopy Assemblies are preserved, packaged and packed in accordance with U.S. Military Specifications or customer's specific packaging instructions.
    The MC1-1C maneuverable parachute assembly designed by the United States Army in 1988 from the basic MC1-1B canopy is used primarily for a premeditated jump when a precision soft landing in a small target area is necessary. The basic canopy is the same as the MC1-1B except 1993, 1995, and 1996 drawing changes as noted are incorporated:

1) The cloth was changed to 0-5-5.0 CFM porosity, specification PIA-C-44378, Type I;
2) The old eleven (11) orifice design was revised to seventeen (17) orifices in the same 11 of the 30 gores; three (3) openings on Gore Nos. 4 and 26;
3) Orifices are tape reinforced horizontally on Gore Nos. 4 and 26 between upper edge at large orifice and lower edge of new lower small opening;
4) Shorter (22') suspension lines are arranged eight (8) lines each instead of seven (7) on the back risers;
5) Shorter (25') control lines are used;
6) The 11-3/4" length pocket bands are used instead of the old 8-3/4" length;
7) All material colors are new U.S. Army color Camouflage Green #483;
8) Reinforcement zigzag stitching was added for main seams Nos. 6 through 25 (orifice area only) – 30" length about suspension lines;
9) Radial tape cut length is now cut 2-1/4" shorter (17') to insure cloth fullness in main seam length.
10) A Reinforcement tape was added under each bridle line on inside of canopy – main seam #5 and #6; #25 and #26. Zigzagged stitched reinforcement on the noted main seams was to provide greater tear resistance of the canopy. Bridle line zigzag stitching is also now backstitched 1-1/2" at beginning of
line stitching.

    These changes create a fast opening canopy with a gliding type descent rate of approximately 4 to 5 feet per second, with more steerability (forward drive) possible. The one disadvantage to this canopy is the higher opening shock, especially of the soldier is heavily loaded with equipment. The drawing changes of 1995 and 1996 were developed by the United States Army to reduce canopy damages from the higher opening shock and other factors. This problem area of canopy damage during deployment is being further evaluated by United States Army Engineering for possible redesign in the near future.
    An additional change was made to the canopy in 2003 incorporating Fluorocarbon treated suspension and vent lines. This treatment of the nylon cord, Type II, 400# tensile strength protects 
the cord from collecting dirt and grit from the drop zone and increases the service life of the canopy. The Pack Assembly P/N 62J4342 was revised in June 1995 by adding one (1) each Static Line Stow Bar to each side of present webbing loops used for stowing the Static Line. These new Stow Bars are used for additional stows at the folded ends of 15'-5" yellow Static Line.
    When packed for service, the complete assembly weighs approximately 32 pounds. The canopy has a nominal diameter of 35 feet and a projected or inflated diameter of 24.5 feet. 
    The deployment bag body is made from 9 ounce Camouflage Green #483 cotton sateen, nylon webbing, cotton webbing and cotton tape. A static line is attached through the break cord strap on inside of the bag under strap pocket and around deployment bag main strap. The body of the pack tray is made from Camouflage Green #483 nylon pack cloth and the components that are sewn to the body are made from nylon pack cloth and nylon webbing. The harness assembly is made primarily from Type XIII Camouflage Green #483 nylon webbing. The chest, back, and leg straps permit size adjustments. Each riser is 30 inches in length with the male fitting of the canopy release permanently attached. The risers are designed so that the control lines may be threaded through the fluted portion and are readily accessible to the jumper. The Capewell lanyard pull release, P/N 100681, or the newer P/N 100681-2 Stainless Steel Slider (Cadmium Chromate Plated) for the canopy risers is incorporated as a safety feature, and allows quick and reliable release of the canopy when landing under high wind conditions or in the water.
