When you say "non-ACAT" program, what do you mean? Do you mean not a Major Defense Acquisition Program (MDAP)? I am not familiar with the term "non-ACAT". Document requirements can be found in two places, DoDI 5000.02 and on our Milestone Document Identification Tool (https://www.dau.mil/tools/t/Milestone-Document-Identification-Tool-(MDID)-). As you will see, all ACAT levels, from I through IV require an LCSP.
