The B-29B was a lightened version on the Superfortress that was built exclusively by Bell-Atlanta. It had all but the tail defensive armament removed, since experience had shown that by that stage in the war the only significant enemy fighter attacks were coming from the rear.

The tail gun was aimed and fired automatically by the new AN/APG-15B radar fire control system that detected the approaching enemy plane and made all the necessary calculations.

The elimination of the turrets and the associated General Electric computerized gun system increased the top speed of the Superfortress to 364 mph at 25,000 feet and made the B-29B suitable for fast, unescorted hit-and-run bombing raids and photographic missions. Most of the weight saved by stripping off the defensive armament was devoted to additional bomb capacity. The right and left side gunners were not carried and the central fire control gunner occasionally acted as an observer and the bombardier's duties could often be performed by the radar operator. The plane could operate with a crew of seven to eight, since fewer gunners were now required. However it often carried up to ten (commander, pilot, navigator, radar operator, bombardier, radio opperator, flight engineer, tail gunner, and two scanners). The scanners were supposed to look out for other planes, both friendly and enemy.

The B-29Bs were not ordered in a single large batch, but were ordered in small batches (sometimes singly) from B-29-BA production lines. It is often difficult to distinguish B-29Bs from "ordinary" B-29s which had been stripped of their machine gun turrets to save weight during General LeMay's fire bombing campaign against Japan during 1945. However, they could be distinguished from B-29s by their serial numbers and by the presence of the external radar antenna in the extreme tail.

A total of 311 B-29Bs were built between January and September of 1945. Most of the B-29Bs were issued to the 315th Bombardment Wing in the Marianas in 1945.

After the war, a special B-29B named Pacusan Dreamboat (44-84061) was converted for long-range flights. It was fitted with modified "Andy Gump" nacelles originally intended for late-model B-29As, R-3350-CA-2 fuel injection engines and specially-designed three-bladed paddle-type propellers. It made several record-breaking long-distance flights, including a nonstop distance record of 7916 miles from Guam to Washington, D. C. in November of 1945.
