Boeing B-52C Stratofortress

The Boeing B‑52C Stratofortress, the third production variant of the iconic B‑52 family, entered service in 1956 as the United States Air Force’s first true intercontinental bomber capable of delivering nuclear or conventional payloads across the globe without refueling. Developed by Boeing at the Seattle plant, 15 B‑52Cs were built, each featuring a longer, 165‑foot wing span, a reinforced fuselage, and upgraded Pratt & Whitney J57‑P‑25W turbo‑jets that produced 15,800 pounds of thrust each. Unlike earlier models, the C‑version incorporated the “Veronica” radar system and a more sophisticated electronic warfare suite, laying the groundwork for later avionics upgrades.

The B‑52C’s design emphasized endurance; it could cruise at 55,000 feet for over 12 hours and, with aerial refueling, achieve a combat radius exceeding 8,800 miles. Its payload capacity—up to 70,000 pounds—allowed carriage of a diverse mix of bombs, missiles, and reconnaissance equipment. Although quickly superseded by the B‑52D’s larger fuel capacity, the C‑model’s operational experience proved critical in refining maintenance protocols, crew ergonomics, and strategic doctrine that sustained the B‑52 line for decades.

The B‑52C’s legacy endures as a pivotal step in establishing the United States’ long‑range deterrent capability, influencing bomber design philosophy and confirming Boeing’s reputation for building durable, adaptable aircraft that remain relevant well beyond their original service life.
