DoD's ATS policy per the 28 July letter is quoted here:
Designated DoD ATS Families are:
Consolidated Automated Support System (CASS)
Integrated Family of Test Equipment (IFTE)
Marine Corps Automatic Test System (MCATES)
Joint Service Electronic Combat Systems Tester (JSECST)
In September 2004, the Service Acquisition Executives agreed upon processes and procedures to implement OSD's policy via a Joint Memorandum of Agreement.
On 2 December 2008, DoD 5000.2 was reissued. The above policy is continued in paragraph 8c(1)(c)2c which states "...a preference for approved DoD Automatic Test Systems (ATS) Families to satisfy ATS requirements."
USAF policy designates the Air Force's Versatile Depot Automatic Test Station as an approved ATS Family as detailed in the Assistant Secretary of the Air Force (Acquisition) memo of 26 November 2007.>>Click Here to View the USAF ATS Policy Letter (29 Sept 2012)
