This antenna was deployed in all Titan silos to work with the SC-901s and to be used as the backup antenna after a nuclear blast hit the silo.  I don’t what happened to that antenna, since now that field is a parking lot….

Been using a Motorola URC-110 but that’s just a little too new to go with the rest of the equipment and think I know where I can get a 403 for the cost of shipping, then have to deal with the whole rock issue.

QRC stands for Quick Reaction Capability and relates to development and deployment of weapon systems ahead of the standard AN/xxx process.  The QRC-160 was developed by the USAF and deployed with the Navy as well.  It later became the ALQ-71.

USAF used a number of Navy-developed equipments but I haven’t come across USAF to USN transfers. Army-Navy sharing was not common (R-390A being a notable exception) And of course USMC used lots of Army gear.
