		   ELECTRONIC EQUIPMENT OF B-29 "Enola Gay."

              (As furnished by the Smithsonian Air-Space Museum)

Designation	  Description and Main Component
--------------------------------------------------------------------------
APN-9		LORAN Receiver.  R-65; 1.6-3.3 MC
APQ-2		Radar Jammer.  T-9/ Xmtr, 200-550 MC, 15 W
APT-1		Radar Jammer.  T-28/ Xmtr, 70-210 MC, 30 W
APT-2		Radar Jammer.  T-26/ Xmtr, 450-710 MC, 8 W
ARC-3		VHF Command Radio Set. R-77/ & T-26/, 100-156 MC, 8 W
ARN-5		Glide Path ILS Receiver.  R-47 or R-57, 332-334 MC
ARN-7		Radio Compass Receiver.  R-101/, 100-1750 KC  
ARR-5		Countermeasures Receiver.  R-44/, 0.5-143 MC
ARR-7		Countermeasures Receiver.  R-45/, 0.54-43 MC

Note:	It seems strange that no HF (3-9 MC) communication gear was aboard.
	The ARC-5 radio set (improved SCR-274N) was in use at this time; 
or an ART-13 transmitter could have been used in conjunction with counter-
measures receiver R-44/, or a separate BC-348. Perhaps the VHF ARC-3 radio 
was used to communicate with the accompanying photo-reconnaisance B-29, 
which could then have then relayed the information back to Siapan.

    But the list is according to the Smithsonian Museum's date as to when
they acquired the aircraft, and not necessarily that which was aboard for 
the Hiroshima Mission.  In this case, the gear might well have included 
an IFF set, such as the familiar APX-6.

    The equipment roster of the Nagasaki Mission B-29 "Bach's Car" would also
be desirable to have, especially for comparative purposes....
