[Milsurplus] SC-901X questions

[Ray Fantini]

Think they were intended to push up thru tons of debris so what’s a couple inches of as vault and a hybrid going to do to stop it?  There was just a TV show on last night “Mysteries of the Abandon” that profiled the old Safeguard Stanley R. Mickelsen complex in the Dakotas with its PAR radar pyramid, Spartan and Sprint launch sites and everything that was put in place there but never became operational because of the ABM treaty.
They referred to four separate antennas structures that were capable of pushing up thru any blast debris. Would assume that they were the same thing.
Never fails to amaze me the incredible facilities, equipment and expense involved with the cold war and how no one remembers it today.
Have been just getting into Mike missile technology and deployment in the last couple years and am impressed on just how big a program that was, before that reading and learning about how Agena-Corona and the NRO had their own space program and all the people, control sites and facilities involved makes you think that the people of that generation were capable of almost anything. Look forward to visiting the US Air Force Museum in Dayton again this year where they have several exhibits including a Corona payload and the C-119 recovery aircraft just to see that stuff again.
I know that has nothing to do with the SC-901 but just wanted to drive this thread further off target.

Wouldn’t that be funny?

If it’s still there may be an unfortunate hydraulic event can cause it to deploy and harpoon a Prius!

When I worked a Rockwell Collins, there was an underground antenna system in front of building 413.  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….

The good old days…..

Lots of stuff sneaks thru as special requirements or programs, look at the RF-301 that’s not exactly Mill Spec but it became the AN/URC-53 because there was a need. Other radios never got AN designations despite wide use like the VHF-FM RF-403 transceivers.
Would love to speculate that one of the Navy’s most loved family of radios that includes the R-1051 and URT-23 were the love child of the SC-901 and General Dynamics and sprung forth the USAF requirements for a synthesized SSB radio for missile silos.

Have thought about installing a RF Technology RF-403 in the mutt, being it would be a period correct radio that can be installed for two meters. 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.

During the Vietnam War, the USAF developed aircraft jammers such as the QRC-160. 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.

Hue has the SC transceiver so the military “equivalent” is the RT-618/UR info found in the URC-35 manual.

Speaking of which, if this thing was designed for the USAF, why the goofy commercial model number and not an AN/xxx compliant designation????

Has anyone got a dated component or inspection stamp to help figure out the chicken-egg history? I bet there is a good story here but I don’t know what it is.

Yes sometimes the Navy will pay R&D costs on a project that has spinoffs or versions for other services. 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.

I sure wish someone had written a history of all this procurement.

Nick, puzzled as usual.
