VB-3 Razon Bomb
Razon allowed a bomber crew to send radio corrections in both range and azimuth after release. The name combined the words range and azimuth. A control operator watched flares on the weapon and transmitted commands intended to correct its path. B-29 crews used Razon against bridges and other point targets that were difficult to hit with unguided bombs.

The story behind the display
Guidance did not remove uncertainty. The crew needed a clear view, accurate judgment, reliable control signals, and time to remain on a predictable course. Razon nevertheless formed part of the practical experience that led toward later precision-guided weapons.
History & service
The VB-3 Razon (for range and azimuth) was a standard 1,000-pound general purpose bomb fitted with flight control surfaces. Development of the Razon began in 1942, but it did not see use during World War II.
19th Bomb Group B-29s dropped 489 Razons during the Korean War, the first in August 1950. Razons were not ideal weapons. For instance, the warhead was usually not big enough to drop a bridge (it took on average four Razon hits). Also, about one-third of those dropped did not respond to radio control. Despite these difficulties, B-29 bombardiers destroyed 15 bridges with Razon bombs.

Air power in a limited war
The Korean War brought early jet combat into the same theater as piston fighters, large bombers, helicopters, and transports. Different technologies served different needs. Fast fighters contested the air, while other aircraft attacked supply routes, supported troops, carried equipment, gathered information, and evacuated casualties. The mountainous terrain and severe weather made those tasks especially demanding.
The conflict also exposed the limits of air power used within a larger political and military struggle. Aircraft could damage bridges and transportation networks, but opposing forces adapted, repaired, dispersed, and moved under cover. Supporting troops required communications and coordination close to the ground. Maintaining operations depended on suitable bases and an extensive flow of supplies.
The surviving artifacts show why a gallery cannot be understood through jet fighters alone. A tent, vehicle, radio, flight nurse's equipment, or rescue helicopter belongs to the same operational history. The stories of individual airmen are compelling because they took place within that complicated setting. Cross-links to the Second World War and later Cold War galleries reveal both continuity and change: familiar aircraft found new roles, jet performance expanded, and rescue systems developed further. The war ended in an armistice, making its history one of service and sacrifice within an unresolved division as well as one of technological change.
