Darpa contract numbers

Hi Guys,

Does anybody here know where I can lookup a DARPA contract number and find
out details of the project?

I picked up a VHF aviation radio from a surplus store and for the life of
me, I can't seem to find any information on it. There is a sticker on the
back stating serial number, DARPA contract number and few other things, but
I need to find pinout information. I believe the unit is an ADF (by the
frequency range on the dials) but I really would like to find any info
available.

Can anyone help?

Thanks
