SINCGARS: Missing Installation Kits

| May 22, 2020

Dear Editor,

I serve as the SINCGARS team lead at CECOM. We manage the SINCGARS installation kits (IKs). From discussions with subject matter experts in our division, we discovered that the available information to the field regarding SINCGARS is inadequate. 

SB 11-131-2 (Oct 11) covers a large majority of SINCGARS IKs for different vehicles and radios. However, there are very important information gaps and instructions that are missing.

As a result, it seems that units are ordering kits they don’t require because they need components in the available kits. Sometimes, this leads to a false demand base being captured, which could lead to a shortage of items the field actually needs. Also, the field could end up spending more money than necessary by procuring the wrong kit.

To help correct these issues, the SINCGARS team put together the following info, which lists kits that weren’t included or didn’t have NSN information listed in the SB. In addition, the team added the installation reference TBs that all of these IKs are covered in.

*SINCGARS system installations on these vehicles require that TACOM platform-specific C5ISR interface kits are installed and complete. See specific vehicle TM(s) for additional C5ISR interface kit component listings. Platform-specific C5ISR interface kits are generally installed in production and include necessary C5ISR LRU mounting provisions and power interconnects.
