Rigging Supply Loads on a 12-Foot, Type V Platform for
Low-Velocity Airdrop
DESCRIPTION OF LOAD
3-1. Bulk supplies consisting of rations, equipment, fuel, ammunition, or other items of general supply
are rigged on a 12-foot, type V airdrop platform with G-11 cargo parachutes. Items packaged or configured
so that they can be restrained by endboards and lashings can be airdropped using these procedures.
Modifications to the honeycomb, endboards, and lashings may be necessary to allow for items of different
sizes and shapes from those shown. For extraction purposes, the rigged load must weigh at least 3,780
pounds. Refer to FM 4-20.102/MCRP 4-11.3J/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5 for the
weight limitations for the number of parachutes to be used.
PREPARING PLATFORM
3-2. Prepare a 12-foot, type V platform as shown in Figure 3-1.

Step:
1. Inspect, or assemble and inspect, a 12-foot, type V platform as outlined in TM 10-1670-
268-20&P/TO 13C7-52-22.
2. Install a tandem link to the front of each platform side rail using holes 1, 2, and 3.
3. Install a tandem link to the rear of each platform side rail using holes 22, 23, and 24.
4. Starting at the front of each platform side rail, install clevises on the bushings bolted to
holes 4, 5, 6, 7, 8, 9, 10, 15, 16, 17, 18, 19, 20, and 21.
5. Starting at the front of the platform, number the clevises 1 through 14 on the right side,
and 1A through 14A on the left side.
6. Label the tiedown rings according to FM 4-20.102/MCRP 4-11.3J/NAVSEA SS400-AB-
MMO-010/TO 13C7-1-5.

PLACING HONEYCOMB
3-3. Place the honeycomb on the platform as shown in Figure 3-2.
Notes.
1. When ammunition is dropped, two layers of honeycomb are required.
2. When rigging this load for airdrop on a drop zone with ground elevation of 6,000 to 10,000
feet, add an additional layer of honeycomb.
3. Adjust the dimensions of the honeycomb to fit the items being dropped.
4. Do not cover the extraction bracket with honeycomb.

1 Glue two full 36- by 96-inch sheets of honeycomb together. Center them 16 inches from
the front edge of the platform.
2 Make a stack as in step 1 above and place it flush against the stack placed in step 1.
3 Make a stack as in step 1 above and place it flush against the stack placed in step 2.

POSITIONING AND SECURING LOAD
3-4. Place six 30-foot lashings on the honeycomb, place the load on the honeycomb, and secure the
lashings as shown in Figure 3-3. Adapt the procedures shown for loads configured differently.
CAUTION
Only ammunition listed in FM 4-20.153/MCRP 4-11.3B/TO 13C7-18-41
may be airdropped. Hazardous material must be packaged, marked,
and labeled as required by AFMAN(I) 24-204/TM 38-250.

Notes.
1. This drawing is not to scale.
2. All dimensions are in inches.
3. The dimensions of the endboards will vary, depending on the load being rigged. The
endboards must be even with the top of the load.

Rigging Forward Area Surgical Team (FAST) Equipment on
a 12-Foot, Type V Platform for Low-Velocity Airdrop
DESCRIPTION OF LOAD
4-1. The FAST equipment is rigged as a bulk supply load on a 12-foot, type V airdrop platform with G-
11 cargo parachutes. These procedures may be used to rig other bulk supply loads consisting of rations,
equipment, fuel, lubricants, ammunition or other items of general supply. As load weights can vary widely,
the parachute requirements must be computed for each load. For extraction purposes, the rigged load must
weigh at least 3,780 pounds. Refer to FM 4-20.102/MCRP 4-11.3J/NAVSEA SS400-AB-MMO-010/TO
13C7-1-5 for the weight limitations for the number of parachutes to be used.
PREPARING PLATFORM
4-2. Prepare a 12-foot, type V platform as shown in Figure 4-1.
