B-52A
Only three of the first production version, the B-52A, were built, all loaned to Boeing for flight testing.
The first production B-52A differed from prototypes in having a redesigned forward fuselage.
The bubble canopy and tandem seating was replaced by a side-by-side arrangement and a 21 inch (53 cm) nose
extension accommodated more [Vous devez être inscrit et connecté pour voir ce lien] and a new 6th crew member.

Re: Boeing B-52 Stratofortress
In the rear fuselage a tail turret with four 0.50 inch (12.7 mm) machine guns with a fire-control system, and a [Vous devez être inscrit et connecté pour voir ce lien] system to augment engine power with a 360 US gallon (1,363 L) water tank was added.
The aircraft also carried a 1,000 US gallon (3,785 L) external fuel tank under each wing.
The tanks acted as dampeners to reduce wing flex and also kept wingtips close to the ground for ease of maintenance.

Liquid oxygen and hydrogen peroxide tanks were installed in the bomb bays to fuel the X-15 before launch.
First flight with X-15 was on 19 March 1959, with the first launch on 8 June 1959.
The NB-52A, named "The High and Mighty One" carried the X-15 on 93 of the program's 199 flights.

B-52B/RB-52B
The B-52B was the first version to enter service with the USAF on 29 June 1955, with the [Vous devez être inscrit et connecté pour voir ce lien] at [Vous devez être inscrit et connecté pour voir ce lien] in California. This version included minor changes to engines and avionics in the attempt to fix minor problems.
Temporary grounding of the aircraft after a crash in February 1956 and again the following July caused training delays, and at mid-year there were still no combat-ready B-52 crews.[Vous devez être inscrit et connecté pour voir ce lien]

Re: Boeing B-52 Stratofortress
Of the 50 B-52Bs built, 27 were capable of carrying a reconnaissance pod as RB-52Bs (the crew was increased to eight in these aircraft).
The 300 pound (136 kg) pod contained radio receivers, a combination of K-36, K-38, and T-11 cameras, and two operators on downward-firing [Vous devez être inscrit et connecté pour voir ce lien].
The pod required only four hours to install.

B-52C
In the B-52C the fuel capacity (and range) was increased to 41,700 US gallons by adding larger 3000 US gallon underwing fuel tanks.
The gross weight was increased by 30,000 pounds (13,605 kg) to 450,000 pounds.
The belly of the aircraft was painted with [Vous devez être inscrit et connecté pour voir ce lien] paint, which was intended to reflect thermal radiation away after a nuclear detonation.

RB-52C
The RB-52C was the designation initially given to B-52Cs fitted for reconnaissance duties in a similar manner to
RB-52Bs.
As all 35 B-52Cs could be fitted with the reconnaissance pod, the RB-52C designation was little used and was quickly abandoned.

B-52D
The B-52D was a dedicated long-range bomber without a reconnaissance option.
The Big Belly modifications allowed the B-52D to carry heavy loads of conventional bombs for [Vous devez être inscrit et connecté pour voir ce lien] over Vietnam, while the Rivet Rambler modification added the Phase V ECM systems, which was better than the systems used on most later B-52s.
