The $3 billion cost of design and production (equivalent to $51 billion in 2022), [1] far exceeding the $1.9 billion cost of the Manhattan Project, made the B-29 program the most expensive of the war. The B-29 remained in service in various roles throughout the 1950s, being retired in the early 1960s after 3,970 had been built.
The newer, but still 1980s-era B-2 Spirit stealth bomber costs $150,741 an hour to fly. The older and notoriously hard to maintain B-1B Lancer swing-wing bomber costs the most of all at $173,014 ...
The LRS-B is intended to perform any long range mission, rather than one specialized mission, which drove up the cost of the B-2. The USAF expects it to cost $1 billion each with development costs factored in, and aims for a per-aircraft cost of $550 million, considered reasonable for a limited production run military aircraft.

The USAAF chose to attack aircraft factories and component plants. On August 17, 1943, 230 Fortresses attacked a ball-bearing plant in Schweinfurt and again two months later, with 291 bombers, in the second raid on Schweinfurt. The works was severely damaged but at a huge cost: 36 aircraft lost in the first raid, 77 in the second.
In December 2022, the cost of the B-21 was estimated at $700 million per aircraft. [46] At the time, Air Force officials estimated that they would spend at least $203 billion over 30 years to develop, purchase, and operate a fleet of at least 100 B-21s.
The B-29A was an improved version of the original B-29 production model. This is the definitive wartime variant of the B-29. All 1,119 B-29A's were built at the Boeing plant in Renton, Washington, formerly used by the United States Navy. Enhancements made in the B-29A included a better wing design and defensive modifications.
The sticker price is expected to be part of the appeal of the B-21, which clocks in at $692 million per aircraft. That price is a relative bargain compared to the over $2 billion cost per plane of ...
A B-29 nicknamed "Slick's Chicks" collided with a B-29 (42-24815) on 10 February 1945. Both planes crashed into the fields of Akuzuma. Both planes crashed into the fields of Akuzuma. The bomber had broken up into two pieces not far from each other, fuselage landing at a paddy field while the tail landed next to the Akizuma Bridge.
