Question:  Henry Eugene "Red" Erwin, Sr. is a recipient of the Medal of Honor which he earned aboard a heavy bomber whose design exceeded the cost of what?

<P0-S0>  He earned the award as a staff sergeant and radio operator aboard a B-29 Superfortress in the Asia-Pacific theater. <P0-S1>  During a 1945 bombing mission over Koriyama, Japan, a white phosphorus bomb prematurely ignited in his aircraft and seriously wounded him. <P0-S2>  As smoke filled the plane, he picked up the burning device and carried it through the aircraft to the cockpit where he tossed it out a window. <P0-S3>  Although he suffered severe burns, he successfully saved his plane and all crew members aboard by disposing of the incendiary/smoke-generating bomb. <P0-S4> Henry Eugene "Red" Erwin, Sr., (May 8, 1921 – January 16, 2002) was a United States Army Air Forces airman and a recipient of the U.S. military's highest decoration—the Medal of Honor—for his actions in World War II. <SEP> <P1-S0> "Kampfgeschwader" 40 (KG 40) was a Luftwaffe medium and heavy bomber wing of World War II, and the primary maritime patrol unit of any size within the World War II Luftwaffe. <P1-S1>  It is best remembered as the unit operating a majority of the four-engine Focke-Wulf Fw 200 "Condor" maritime patrol bombers. <P1-S2>  The unit suffered from the poor serviceability and low production rates of the Fw 200 bombers, and from repeated diversion of its long-haul capability aircraft to undertake transport duties in various theatres, especially for the airlift operations to supply encircled forces in the Battle of Stalingrad. <P1-S3>  Later in the war, KG 40 became one of several Luftwaffe bomber wings to use the Heinkel He 177A heavy bomber. <SEP> <P2-S0>  It was one of the largest aircraft operational during World War II and featured state of the art technology. <P2-S1>  Including design and production, it was the single most expensive weapons project undertaken by the United States in World War II, exceeding the cost of the Manhattan Project by between $1 and 1.7 billion. <P2-S2>  Innovations introduced included a pressurized cabin, dual-wheeled, tricycle landing gear, and an analog computer-controlled fire-control system that directed four remote machine gun turrets that could be operated by a single gunner and a fire-control officer. <P2-S3>  A manned tail gun installation was semi-remote. <P2-S4>  The name "Superfortress" continued the pattern Boeing started with its well-known predecessor, the B-17 Flying Fortress. <P2-S5>  Designed for the high-altitude strategic bomber role, the B-29 also excelled in low-altitude nighttime incendiary bombing missions. <P2-S6>  One of the B-29's final roles during World War II was carrying out the atomic bomb attacks on Hiroshima and Nagasaki. <P2-S7> The Boeing B-29 Superfortress is a four-engine propeller-driven heavy bomber designed by Boeing, which was flown primarily by the United States during World War II and the Korean War. <SEP> <P3-S0> The Boeing B-17 Flying Fortress is a four-engine heavy bomber developed in the 1930s for the United States Army Air Corps (USAAC). <P3-S1>  Competing against Douglas and Martin for a contract to build 200 bombers, the Boeing entry (prototype Model 299/XB-17) outperformed both competitors and exceeded the air corps' performance specifications. <P3-S2>  Although Boeing lost the contract (to the Douglas B-18 Bolo) because the prototype crashed, the air corps ordered 13 more B-17s for further evaluation. <P3-S3>  From its introduction in 1938, the B-17 Flying Fortress evolved through numerous design advances, becoming the third-most produced bomber of all time, behind the B-24 and the multirole Ju 88.
