Nick, 

I should have also added, that a service branch often supplied another branch from existing or on going production without issuing a change to the contract number on the equipment tags. If the Navy got an order from the Air Force for one thousand additional Sidewinder, for example, they simply enlarged the existing production order without making any changes to the equipment tag. Of course they kept track of the S/Ns. This means that the equipment tag means nothing about the actual user.

I learned about this when working for a defense contractor. Of course, when things go back to the depot for overhaul, the dice are thrown again….

Best, Francesco

Nick, 

Usually, one of the services owns the production and relationship with the customer for a program. For example, the Navy owned the Sidewinder missile, and the Air Force had to procure them through the Navy.

I believe that the R-390/URR was owned by the ARMY. The contract number tells only who was paying for that radio.

This approach streamlines the procurement process, but can create supply issues for the non owner of the program, as the owner often prioritizes his/her own service needs.

The F-4 program was originally Navy, but then it was split with the Air Force. The Marines owned the RF-4 programs.

Most all the R-390A contracts were numbers like 42428-PC-59, clearly an army Signal Corps contract. But there are some like DAAB05-68-C-0040 - is that also Army?
and what about FR-36-039-N-6-00189(E)???

AFAIK, the only Navy contract was for the 5 Fowler units under N00024-84-C-202 plus an EAC spares contract N00126-70-C-0359

Otherwise all the Navy ones were procured by the Signal Corps?
