Yes, it is. The XB-52 was the very first sample, and it was a test model.
And being "rolled out" doesn't mean that it flew: it was simply rolled out
to display it to the public. Here is a brief synopsis:
JUL 48 USAF orders two prototypes of B-52 w/turboprop engines
DEC 48 Turboprop model scrapped for all-jet Model 464
FEB 51 13 production B-52's ordered
29 NOV 51 XB-52 (49-230) rolled out for display, then returned for further
2 OCT 52 XB-52 (49-230) flew
15 MAR 52 YB-52 (49-231) rolled out
15 APR 52 YB-52 (49-231) flew
5 AUG 53 first production model. B-52A (52-001) flies -- later joined by
52-002 and -003
29 JUN 55 93rd HBW at Castle AFB in California receives first operational
